Bose Ultra Open Earbuds

Practical Design

The premium Bose Clip-on headphones feature an unusual flexible Flex-band clip: it gently wraps around the ear edge, does not create extra pressure, and securely holds the device in place. The design also includes a cylindrical battery module functioning as a counterweight, making the model almost unnoticeable even during prolonged use. These cylinders also house mechanical buttons with clear tactile feedback — this control reduces the risk of accidental presses typical of touch panels. IPX4 protection ensures that you don’t have to fear sweat during workouts and light drizzling rain, but the headphones are not intended for heavy rain.

Excellent Sound by Bose

The main advantages of Bose Ultra Open Earbuds are linked more with audio quality than with ergonomics. Dynamic drivers work in tandem with the proprietary OpenAudio directed sound technology, which helps reduce leakage. Engineers achieved rich, spacious bass — a rarity for open-type models. The high playback level is complemented by support for Immersive Audio spatial sound and the aptX Adaptive codec. The first function creates a concert presence effect and adapts the soundstage to the user’s head movements, which is rare among Open-Ear solutions. The second codec reduces latency and allows high-resolution audio transmission without noticeable quality loss.

Decent Autonomy

It is also worth noting the support for Multipoint and extended customization options through the proprietary app. On a single charge, the model works for up to 7.5 hours, and with Immersive Audio activated — up to 4.5 hours. With recharging from the included case, the total autonomy reaches 19.5 hours. In this aspect, the headphones lag behind many competitors, so this can be considered a weak point of the model. Another obvious downside is the high cost. But if you need one of the best Clip-on headphones in terms of sound quality, Bose Ultra Open Earbuds are a top favorite.
