SuperTooth U8 True Wireless Earbuds

The SuperTooth U8 are in-ear Bluetooth 5.3 headphones built for sport and daily use. They ship with four pairs of ear caps so you can secure a stable, comfortable fit during workouts or commutes.

Bluetooth 5.3 range and latency

Bluetooth 5.3 delivers a 30 ft line-of-sight range and 10 ft through obstacles. The standard does not support smartwatch pairing, so a phone, tablet or computer is required for audio streaming and calls.

IPX7 rating and USB-C charging

An IPX7 coating protects the buds from sweat, rain and splashes during intense sessions. A USB-C cable recharges the case in two hours for up to 16 hours of total playback.
