Business Combination and Asset Acquisition [Abstract]
Business Combinations	Business CombinationsDuring the first quarter of fiscal 2022, the Company completed two acquisitions for a combined aggregate cash consideration of approximately $27.1 million. The acquisitions brought talented employees and strategic intellectual property ("IP") to enhance the experience of Sonos products. The Company accounted for these transactions as business combinations and allocated the purchase consideration to assets acquired and liabilities assumed. In aggregate, $0.2 million was attributed to net assets acquired, $6.2 million to intangible assets, $1.5 million in deferred tax liabilities, and $22.2 million to goodwill. The goodwill recognized was primarily attributable to the assembled workforce and expected post-acquisition synergies from these acquisitions. Goodwill is not deductible for tax purposes. The transaction costs associated with the acquisitions were not material and were expensed as incurred, as general and administrative expenses in the condensed consolidated statements of operations and comprehensive income. Pro forma results of operations for these acquisitions have not been presented because they are not material to the Company's condensed consolidated financial statements, either individually or in the aggregate.
