Warranty

1 of 1 differ

Manufacturer warranty (source market)iThe maker's warranty period for the exact SKU or configuration and market named in the source note. It applies only to that stated market, not every regional variant. Statutory consumer rights are excluded. The base term is stored. An extension that needs registration goes in the source note.

1year9Maker product pagesupport.jbl.com/howto/jbl-warranty-information-us/000028546.htmlRead 8 October 2026US powered Home Audio warranty is one year from delivery for authorized-US-reseller purchase and US use, unless the supplied warranty card states another term. Five-year passive-speaker term and Australian statutory coverage are not applied.

2years6Maker product pagemarshall.com/us/en/policies/warrantyRead 8 October 2026Current US Headphones & Speakers policy provides two years for purchases through Marshall.com or an authorized US dealer. Policy states applicable to purchases after February 13, 2025. Generic embedded product return copy says one year except two years direct, and B&H says one year. Current explicit US warranty terms are used, with those conflicting summaries preserved. Statutory rights are separate.
