What to know before buying

Battery figures depend on operating mode: the detailed specifications list 9.5 hours per charge and up to 42.5 hours with the case when ANC is off, versus 5.5 hours and up to 24.5 hours with ANC on. The general 42.5-hour claim is not an ANC-on estimate.
Customer feedback praises sound and noise cancellation, but reports vary on whether the earbuds stay secure, remain comfortable over time, charge reliably and continue working. Consider fit especially if you plan to wear them for long sessions.

Listing details to confirm

The listing is inconsistent about water protection: one field says "Waterproof," while the manufacturer detail specifies IP54 for the earbuds and IPX2 for the case. Check the protection rating relevant to your use rather than treating the broad label as a rating.

Who is it for?

A good fit for

Listeners wanting adaptive noise cancellation and the option to adjust it in an app.
People who move between phone and laptop and want to keep both connected.
Buyers who prefer in-ear earbuds and want distinct ANC-on and ANC-off battery estimates.

Less suited to

Anyone who needs the longest stated runtime while keeping ANC on.
Buyers who need a confirmed water-protection rating without resolving the listing’s conflicting descriptions.
People who already know in-ear earbuds tend to loosen or cause soreness for them.
