The performance and simplicity of our advanced, comprehensive solutions offer unprecedented levels of functionality, reliability and scalability. Basis of Presentation: The fiscal year for ClearOne is the 12 months ending on December 31. The consolidated financial statements include the accounts of ClearOne and its subsidiaries. All significant inter-company accounts and transactions have been eliminated.These accompanying interim unaudited condensed consolidated financial statements have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) and are not audited. Certain information and footnote disclosures that are usually included in financial statements prepared in accordance with generally accepted accounting principles in the United States (“GAAP”) have been either condensed or omitted in accordance with SEC rules and regulations. The accompanying condensed consolidated financial statements contain all adjustments, consisting of normal recurring accruals, necessary for a fair presentation of our financial position as of March 31, 2018 and December 31, 2017, the results of operations for the three months ended March 31, 2018 and 2017, and the cash flows for the three months ended March 31, 2018 and 2017. The results of operations for the three months ended March 31, 2018 and 2017 are not necessarily indicative of the results for a full-year period. These interim unaudited condensed consolidated financial statements should be read in conjunction with the financial statements included in our Annual Report on Form 10 -K for the year ended December 31, 2017 filed with the SEC.Significant Accounting Policies: The significant accounting policies were described in Note 1 to the audited consolidated financial statements included in the Company’s annual report on Form 10 -K for the year ended December 31, 2017. There have been no changes to these policies during the three months ended March 31, 2018 that are of significance or potential significance to the Company except for the change in revenue recognition policy described below.Adoption of New Revenue Standard: On January 1, 2018, as required, the Company adopted ASU No. 2014 -09 - Revenue from Contracts with Customers (Topic 606 ) (“ASU 2014 -09” ), ASU No. 2015 -14 - Revenue from Contracts with Customers (Topic 606 ): Deferral of the Effective Date (“ASU 2015 -14” ), ASU No. 2016 -08 - Revenue from Contracts with Customers (Topic 606 ): Principal versus Agent Considerations (“ASU 2016 -08” ), ASU No. 2016 -10 - Revenue from Contracts with Customers (Topic 606 ): Identifying Performance Obligations and Licensing (“ASU 2016 -10” ), ASU No. 2016 -12 - Revenue from Contracts with Customers (Topic 606 ): Narrow-Scope Improvements and Practical Expedients (“ASU 2016 -12” ) and ASU No. 2016 -20 - Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers” (“ASU 2016 -20” ) (collectively “the New Revenue Standard”). To conform to the New Revenue Standard, the Company modified its revenue recognition policy as described further below.Change in Accounting Policy: On January 1, 2018, the Company adopted the New Revenue Standard using the modified retrospective method, applying the guidance to all open contracts and recognized an adjustment to increase retained earnings by $2,783, reduce deferred product revenue by $4,338 and reduce distributor channel inventories by $1,555 as of that date. The comparative financial information has not been restated and continues to be presented under the accounting standards in effect for the respective periods. The Company applied the practical expedient and has not disclosed the revenue allocated to future shipments of partially completed contracts.Our accounting policy before this change is described below. Revenue from product sales to distributors was not recognized until the return privilege had expired or until it can be determined with reasonable certainty that the return privilege had expired, which approximated when the product was sold-through to customers of our distributors (dealers, system integrators, value-added resellers, and end-users), rather than when the product was initially shipped to a distributor. At each quarter-end, we evaluated the inventory in the distribution channel through information provided by our distributors. The level of inventory in the channel fluctuated up or down each quarter based upon our distributors’ individual operations. Accordingly, each quarter-end deferral of revenue and associated cost of goods sold were calculated and recorded based upon the actual channel inventory reported at quarter-end. Further, with respect to distributors and other channel partners not reporting the channel inventory, the revenue and associated cost of goods sold were deferred until we received payment for the product sales made to such distributors or channel partners.Now, after the change in the accounting policy, substantially all of the Company’s revenue is recognized following the transfer of control of the products to the customer, which typically occurs upon shipment or delivery depending on the terms of the underlying contracts. During the quarter ended March 30, 2018, revenue decreased by $852 due to the impact of the adoption of the New Revenue Standard.Revenue Recognition Policy: The Company generates revenue from sales of its audio and video conferencing equipment to distributors, system integrators and value-added resellers. The Company also generates revenue, to a much lesser extent, from sale of software and licenses to distributors, system integrators, value-added resellers and end-users. The Company recognizes revenue when it satisfies a performance obligation in an amount reflecting the consideration to which it expects to be entitled. For sales agreements, the Company has identified the promise to transfer products, each of which are distinct, to be the performance obligation. The Company applies a five -step approach in determining the amount and timing of revenue to be recognized: (1 ) identifying the contract with a customer, (2 ) identifying the performance obligations in the contract, (3 ) determining the transaction price, (4 ) allocating the transaction price to the performance obligations in the contract and (5 ) recognizing revenue when the performance obligation is satisfied. Substantially all of the Company’s revenue is recognized at the time control of the products transfers to the customer.Sales agreements with customers are renewable periodically and contain terms and conditions with respect to payment, delivery, warranty and supply, but typically do not require mandatory purchase commitments. In the absence of a sales agreement, the Company’s standard terms and conditions at the time of acceptance of purchase orders apply. The Company considers the customer purchase orders, governed by sales agreements or the Company’s standard terms and conditions, to be the contract with the customer. The Company evaluates certain factors including the customer’s ability to pay (or credit risk).In determining the transaction price, the Company evaluates whether the price is subject to refund or adjustment to determine the net consideration to which the Company expects to be entitled. Sales to distributors, are typically made pursuant to agreements that provide return rights with respect to discontinued or slow-moving products, referred to as stock rotation. Sales to distributors can also be subject to price adjustment on certain products, primarily for distributors with ship and credit rights. Although payment terms vary, most distributor agreements require payment within 45 days of invoicing.The Company recognizes revenue when it satisfies a performance obligation. The Company recognizes revenue from sales agreements upon transferring control of a product to the customer. This typically occurs when products are shipped or delivered, depending on the delivery terms, or when products that are consigned at customer locations are sold to dealers or end users. Revenue recognized during the quarter ended March 31, 2018 for equipment sales was $7,109 and for software and licenses was $180. Sales returns and allowances are estimated based on historical experience. Provisions for discounts and rebates to customers, estimated returns and allowances, ship and credit claims and other adjustments are provided for in the same period the related revenues are recognized, and are netted against revenues. For returns, the Company recognizes a related asset for the right to recover returned products with a corresponding reduction to cost of goods sold. The Company reviews warranty and related claims activity and records provisions, as necessary.Frequently, the Company receives orders with multiple delivery dates that may extend across reporting periods. Since each delivery constitutes a performance obligation, the Company allocates the transaction price of the contract to each performance obligation based on the stand-alone selling price of the products. The Company invoices the customer for each delivery upon shipment and recognizes revenues in accordance with delivery terms. Although payment terms vary, distributors typically pay within 45 days of invoicing and dealers pay within 30 days of invoicing. As scheduled delivery dates are within one year, revenue allocated to future shipments of partially completed contracts are not disclosed.The Company has elected to record freight and handling costs associated with outbound freight after control over a product has transferred to a customer as a fulfillment cost and include it in cost of revenues. Taxes assessed by government authorities on revenue-producing transactions, including value-added and excise taxes, are presented on a net basis (excluded from revenues) in the Consolidated Statements of Operations and Comprehensive Income. Recent Accounting Pronouncements: In February 2016, the FASB released ASU No. 2016 -02, Leases (Topic 842 ) to bring transparency to lessee balance sheets. The ASU will require organizations that lease assets (lessees) to recognize assets and liabilities on the balance sheet for the rights and obligations created by all leases with terms of more than 12 months. The standard will apply to both types of leases-capital (or finance) leases and operating leases. Previously, GAAP has required only capital leases to be recognized on lessee balance sheets. The standard is effective for fiscal years beginning after December 15, 2018 and interim periods within fiscal years beginning after December 15, 2018. Early application will be permitted for all organizations. The Company has not yet selected a transition method and is currently evaluating the effect that the updated standard will have on the consolidated financial statements.In August 2016, the FASB released ASU No. 2016 -15, Classification of Certain Cash Receipts and Cash Payments, which addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. ASU 2016 -15 became effective for the Company on January 1, 2018. ASU 2016 -15 had no material impact on our consolidated financial statements.In May 2017, the FASB issued ASU No. 2017 -09, Compensation-Stock Compensation (Topic 718 ): Scope of Modification Accounting. The new guidance provides clarity and reduces both (1 ) diversity in practice and (2 ) cost and complexity when applying the guidance in Topic 718, Compensation-Stock Compensation, to a change to the terms or conditions of a share-based payment award. The accounting standard update became effective for the Company on January 1, 2018. ASU 2017 -09 did not have any material impact on our consolidated financial statements. |

| Fair Value Disclosures [Text Block] | 9. Fair Value MeasurementsThe fair value of the Company’s financial instruments reflects the amounts that the Company estimates it will receive in connection with the sale of an asset or pay in connection with the transfer of a liability in an orderly transaction between market participants at the measurement date (exit price). The fair value hierarchy prioritizes the use of inputs used in valuation techniques into the following three levels:Level - Quoted prices in active markets for identical assets and liabilities.1 Level - Observable inputs other than quoted prices in active markets for identical assets and liabilities; quoted prices in markets that are 2 not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. This category generally includes U.S. Government and agency securities; municipal securities; mutual funds and securities sold and not yet settled.Level - Unobservable inputs.3 The substantial majority of the Company’s financial instruments are valued using observable inputs. The following table sets forth the fair value of the financial instruments re-measured by the Company as of March 31, 2018 and December 31, 2017:

| Income Tax Disclosure [Text Block] | 10. Income TaxesThe Company’s forecasted effective tax benefit rate at March 31, 2018 is 27.0%, a 16.2% increase from the 10.8% effective tax rate recorded at December 31, 2017. The 16.2% increase is primarily due to the enactment in 2017 of the Tax Cuts and Jobs act, which resulted in a lower corporate tax rate and a revaluation of the Company's net deferred tax assets. The forecasted effective tax benefit rate of 27.0% excludes jurisdictions for which no benefit from forecasted current year losses is anticipated. Including losses from such jurisdictions results in a forecasted effective tax benefit rate of 26.0%. Our forecasted effective tax rate could fluctuate significantly on a quarterly basis and could change, to the extent that earnings in countries with tax rates that differ from that of the U.S. differ from amounts anticipated at March 31, 2018. After a discrete tax expense of $62, the effective tax benefit rate for the quarter ended March 31, 2018 is 23.7%. The discrete tax expense of $62 is primarily attributable to changes in income tax reserves related to an income tax audit in Hong Kong. |

| Accounting Policies [Abstract] | |
| New Accounting Pronouncements, Policy [Policy Text Block] | Significant Accounting Policies: The significant accounting policies were described in Note 1 to the audited consolidated financial statements included in the Company’s annual report on Form 10 -K for the year ended December 31, 2017. There have been no changes to these policies during the three months ended March 31, 2018 that are of significance or potential significance to the Company except for the change in revenue recognition policy described below.Adoption of New Revenue Standard: On January 1, 2018, as required, the Company adopted ASU No. 2014 -09 - Revenue from Contracts with Customers (Topic 606 ) (“ASU 2014 -09” ), ASU No. 2015 -14 - Revenue from Contracts with Customers (Topic 606 ): Deferral of the Effective Date (“ASU 2015 -14” ), ASU No. 2016 -08 - Revenue from Contracts with Customers (Topic 606 ): Principal versus Agent Considerations (“ASU 2016 -08” ), ASU No. 2016 -10 - Revenue from Contracts with Customers (Topic 606 ): Identifying Performance Obligations and Licensing (“ASU 2016 -10” ), ASU No. 2016 -12 - Revenue from Contracts with Customers (Topic 606 ): Narrow-Scope Improvements and Practical Expedients (“ASU 2016 -12” ) and ASU No. 2016 -20 - Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers” (“ASU 2016 -20” ) (collectively “the New Revenue Standard”). To conform to the New Revenue Standard, the Company modified its revenue recognition policy as described further below.Change in Accounting Policy: On January 1, 2018, the Company adopted the New Revenue Standard using the modified retrospective method, applying the guidance to all open contracts and recognized an adjustment to increase retained earnings by $2,783, reduce deferred product revenue by $4,338 and reduce distributor channel inventories by $1,555 as of that date. The comparative financial information has not been restated and continues to be presented under the accounting standards in effect for the respective periods. The Company applied the practical expedient and has not disclosed the revenue allocated to future shipments of partially completed contracts.Our accounting policy before this change is described below. Revenue from product sales to distributors was not recognized until the return privilege had expired or until it can be determined with reasonable certainty that the return privilege had expired, which approximated when the product was sold-through to customers of our distributors (dealers, system integrators, value-added resellers, and end-users), rather than when the product was initially shipped to a distributor. At each quarter-end, we evaluated the inventory in the distribution channel through information provided by our distributors. The level of inventory in the channel fluctuated up or down each quarter based upon our distributors’ individual operations. Accordingly, each quarter-end deferral of revenue and associated cost of goods sold were calculated and recorded based upon the actual channel inventory reported at quarter-end. Further, with respect to distributors and other channel partners not reporting the channel inventory, the revenue and associated cost of goods sold were deferred until we received payment for the product sales made to such distributors or channel partners.Now, after the change in the accounting policy, substantially all of the Company’s revenue is recognized following the transfer of control of the products to the customer, which typically occurs upon shipment or delivery depending on the terms of the underlying contracts. During the quarter ended March 30, 2018, revenue decreased by $852 due to the impact of the adoption of the New Revenue Standard.Revenue Recognition Policy: The Company generates revenue from sales of its audio and video conferencing equipment to distributors, system integrators and value-added resellers. The Company also generates revenue, to a much lesser extent, from sale of software and licenses to distributors, system integrators, value-added resellers and end-users. The Company recognizes revenue when it satisfies a performance obligation in an amount reflecting the consideration to which it expects to be entitled. For sales agreements, the Company has identified the promise to transfer products, each of which are distinct, to be the performance obligation. The Company applies a five -step approach in determining the amount and timing of revenue to be recognized: (1 ) identifying the contract with a customer, (2 ) identifying the performance obligations in the contract, (3 ) determining the transaction price, (4 ) allocating the transaction price to the performance obligations in the contract and (5 ) recognizing revenue when the performance obligation is satisfied. Substantially all of the Company’s revenue is recognized at the time control of the products transfers to the customer.Sales agreements with customers are renewable periodically and contain terms and conditions with respect to payment, delivery, warranty and supply, but typically do not require mandatory purchase commitments. In the absence of a sales agreement, the Company’s standard terms and conditions at the time of acceptance of purchase orders apply. The Company considers the customer purchase orders, governed by sales agreements or the Company’s standard terms and conditions, to be the contract with the customer. The Company evaluates certain factors including the customer’s ability to pay (or credit risk).In determining the transaction price, the Company evaluates whether the price is subject to refund or adjustment to determine the net consideration to which the Company expects to be entitled. Sales to distributors, are typically made pursuant to agreements that provide return rights with respect to discontinued or slow-moving products, referred to as stock rotation. Sales to distributors can also be subject to price adjustment on certain products, primarily for distributors with ship and credit rights. Although payment terms vary, most distributor agreements require payment within 45 days of invoicing.The Company recognizes revenue when it satisfies a performance obligation. The Company recognizes revenue from sales agreements upon transferring control of a product to the customer. This typically occurs when products are shipped or delivered, depending on the delivery terms, or when products that are consigned at customer locations are sold to dealers or end users. Revenue recognized during the quarter ended March 31, 2018 for equipment sales was $7,109 and for software and licenses was $180. Sales returns and allowances are estimated based on historical experience. Provisions for discounts and rebates to customers, estimated returns and allowances, ship and credit claims and other adjustments are provided for in the same period the related revenues are recognized, and are netted against revenues. For returns, the Company recognizes a related asset for the right to recover returned products with a corresponding reduction to cost of goods sold. The Company reviews warranty and related claims activity and records provisions, as necessary.Frequently, the Company receives orders with multiple delivery dates that may extend across reporting periods. Since each delivery constitutes a performance obligation, the Company allocates the transaction price of the contract to each performance obligation based on the stand-alone selling price of the products. The Company invoices the customer for each delivery upon shipment and recognizes revenues in accordance with delivery terms. Although payment terms vary, distributors typically pay within 45 days of invoicing and dealers pay within 30 days of invoicing. As scheduled delivery dates are within one year, revenue allocated to future shipments of partially completed contracts are not disclosed.The Company has elected to record freight and handling costs associated with outbound freight after control over a product has transferred to a customer as a fulfillment cost and include it in cost of revenues. Taxes assessed by government authorities on revenue-producing transactions, including value-added and excise taxes, are presented on a net basis (excluded from revenues) in the Consolidated Statements of Operations and Comprehensive Income. Recent Accounting Pronouncements: In February 2016, the FASB released ASU No. 2016 -02, Leases (Topic 842 ) to bring transparency to lessee balance sheets. The ASU will require organizations that lease assets (lessees) to recognize assets and liabilities on the balance sheet for the rights and obligations created by all leases with terms of more than 12 months. The standard will apply to both types of leases-capital (or finance) leases and operating leases. Previously, GAAP has required only capital leases to be recognized on lessee balance sheets. The standard is effective for fiscal years beginning after December 15, 2018 and interim periods within fiscal years beginning after December 15, 2018. Early application will be permitted for all organizations. The Company has not yet selected a transition method and is currently evaluating the effect that the updated standard will have on the consolidated financial statements.In August 2016, the FASB released ASU No. 2016 -15, Classification of Certain Cash Receipts and Cash Payments, which addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. ASU 2016 -15 became effective for the Company on January 1, 2018. ASU 2016 -15 had no material impact on our consolidated financial statements.In May 2017, the FASB issued ASU No. 2017 -09, Compensation-Stock Compensation (Topic 718 ): Scope of Modification Accounting. The new guidance provides clarity and reduces both (1 ) diversity in practice and (2 ) cost and complexity when applying the guidance in Topic 718, Compensation-Stock Compensation, to a change to the terms or conditions of a share-based payment award. The accounting standard update became effective for the Company on January 1, 2018. ASU 2017 -09 did not have any material impact on our consolidated financial statements. |
