Single-Ear Open-Ear Headset

The No Sew Bt55-180 is a mono Bluetooth 5.5 headset that hooks over the ear with a 180° rotatable shaft for left or right wear. An open-ear driver leaves the canal unobstructed so the user hears surroundings while listening. It weighs 42 g and charges via Type-C.

Suited for Calls and Awareness

Drivers who need hands-free calls and office workers who must stay alert to conversation will benefit from the open design and 30 h operating time. Buyers who want stereo music, active noise cancellation or a sealed in-ear fit should look at something else.

30 Hours Mono Playtime

The internal battery delivers up to 30 hours of talk or audio playback on one charge and an LED readout shows remaining level. Multi-device pairing lets two phones stay connected without re-pairing. A single 15 mm driver covers 20 Hz response at 32 Ω impedance for voice and light media.
