1:1 replica of the Bose Ultra clip-on open-ear design -- 12 mm driver, 7-hour playback, IPX4 sweat resistance, unique ear-clip that doubles as an ear accessory.
The Bose Ultra Open Ear replica faithfully reproduces the brand's signature clip-on design that grips the ear without entering the ear canal, making it both a listening device and a subtle ear accessory. The ultra-soft silicone flex loop conforms to different ear shapes and stays locked in place during running, cycling, and other vigorous movement without discomfort. A 12 mm dynamic driver unit powers the audio, delivering clear vocals, defined mids, and enough bass to make music engaging. Bose Immersive Audio spatial processing widens the soundstage beyond the physical driver size. Battery life reaches 7 hours per charge; the included charging case contributes an additional 19.5 hours of reserve, and a 10-minute quick-charge session restores 2 hours of playback. IPX4 water resistance handles sweat and light rain. Each unit carries a unique serial number and supports registration. Three-month return window for non-cosmetic defects.
Correct -- the open-ear clip design does not seal the ear canal, so ambient sound passes through. This is a feature for situational awareness, not a noise-canceling setup.
Buyers typically report around 6-8 hours of playback from the earphones, with additional charges available from the carry case.
Yes, the over-ear clip holds the earphones firmly during moderate exercise. For high-intensity training, we recommend testing the fit with your specific ear shape first.
