Dark Black In-Ear Earbuds

These wireless earbuds use Bluetooth 5.4 and active noise cancellation rated at 45dB to suppress up to 90% of ambient sound. The package includes two earbuds, a wireless charging case, a charging cable and three sizes of silicone tips for a secure in-ear fit.

Commuters and Active Users

The 48-hour total playback time with the case suits long travel days or back-to-back shifts, while IPX7 protection handles sweat and rain during workouts. Buyers who need wired connectivity or on-ear comfort should consider a different form factor.

45dB Active Noise Cancellation

The headline specification is the ANC depth of 45dB combined with ENC call clarity, which determines whether these earbuds will meet the noise-reduction needs of a given environment.

Questions about this item

How often will the ear tips need to be replaced for the best seal and hygiene?

The package includes three sizes of silicone ear tips; swap them when they lose elasticity or show wear to maintain the fit needed for 45dB ANC performance.

What limits continuous playback before the case must be recharged?

Each earbud runs up to 6 hours on a single charge, and the case extends total use to 48 hours before you need to plug it in for 1.5 hours.

Do the earbuds get hot or noisy during all-day use?

The in-ear design has no moving parts or fans, so they stay silent and cool even after hours of Bluetooth 5.4 streaming with ANC active.
