What to know before buying

Listing details to confirm

The listing's ANC claim is limited to reducing low-frequency background noise and does not promise complete quiet, especially for sharp or high-frequency sounds. Playback duration is not specified numerically and depends on volume and ANC use. Confirm that the fit and stated moisture resistance suit your needs. The listed 6 millimeter driver conflicts with the feature description's 14.2mm driver, the listed 5.13 g item weight conflicts with the claim of 3.0g per earbud, and Bluetooth version is listed as 5.3 while a highlight claims 5.4. Treat these specifications as unconfirmed and check the selected listing before purchase.
