True Wireless Earbuds with Bluetooth 5.4

These earbuds use Bluetooth 5.4 for stable connections up to 15 metres. Each bud weighs 1 gram and houses a 13 millimetre dynamic driver. The IP7 nano-coating protects against sweat and rain during workouts. A USB-C case provides 60 hours of total playback.

Suits active listeners wanting long battery life

The earhook design keeps buds in place while running or training. Touch controls handle calls and music without reaching for a phone. Four microphones with ENC reduce background noise by 80 percent for clearer calls. Buyers needing aptX or LDAC codecs should look elsewhere.

60-hour total playtime from the charging case

Each charge gives 8 hours of listening and the case recharges the buds six times. A 10-minute top-up adds 2 hours of use. The dual LED display shows exact battery percentage from 1 to 100. This single figure decides if the endurance matches your routine.
