- Balanced sound
- long service life
- convenient
- Centres unclean
- Voices partly nasally discoloured
The Ultra Open earbuds have a warm and balanced sound. However, the mids are not flawless and voices are sometimes nasal. The bass lacks a little power, which is somewhat due to the model type. They cling comfortably to the ears and offer a very long battery life.

- Light and compact
- External noise is not sealed off
- Good sound despite open design
- Very good 360-degree audio
- Simple and precise operation
It's off to a good start - Bose is entering the still young market with an open-ear that sounds good thanks to its close fit to the ear canal and can even keep up with many in-ears. The ear clip design makes them ideal for cyclists. But don't overdo it with the impressive volume in road traffic, because then you might as well go for in-ears!
