Open-Ear Bluetooth 5.4 Headphones

These open-ear headphones rest on top of the ears without entering the canal. They suit listeners who want environmental awareness during workouts, commutes or office calls. The 16.1 mm drivers deliver bass, mids and treble, while built-in microphones target voice isolation for clearer calls. Buyers who need full passive noise blocking or in-ear seal will not get it here.

Bluetooth 5.4 range and latency

Bluetooth 5.4 provides a stable link up to 10 metres or 33 feet. The connection supports audio and video sync for gaming and movies. Obstructions and interference can reduce the practical range below the quoted figure. The headphones have no wired connector, so they cannot be used with devices lacking Bluetooth.

12-hour buds and 60-hour case

Each charge gives 12 hours of continuous play from the earbuds. The charging case stores an extra 48 hours, reaching 60 hours total before the case itself needs recharging. A full recharge of the buds takes 12 hours. Users who need multi-day use without access to a power source will run out.
