Built for long listening sessions

These in-ear earbuds deliver up to 100 hours of total playtime from the charging case, with each bud lasting 8 hours per charge. Bluetooth 5.4 provides a stable connection up to 10 metres. Active noise cancellation reduces ambient sound by 42 dB while four microphones with ENC suppress 90 percent of background chatter during calls. Touch controls handle playback and calls without reaching for your phone.

Upgrade from shorter-life or wired buds

The jump is worth it when you need all-day battery without daily recharging and want effective noise reduction for commuting or open-plan offices. Bluetooth 5.4 cuts latency compared with older versions, and the 10 mm dynamic drivers cover a 60 Hz to 18 kHz response. IP5 water resistance adds durability for workouts or rain that basic models lack.

Check your device and fit before ordering

Ensure your phone, tablet or laptop supports Bluetooth 5.4 for the full feature set. The single-ear coupling design means each bud works independently, so verify mono-mode suits your workflow. A USB Type-C cable is required for the 1.5-hour case charge and the one-hour bud charge. Confirm the in-ear seal feels comfortable for extended wear.
