Love the sound quality and how the bass sounds. The only thing about it is that when having the earphone in my ear for a long period the back side of it hurts my ear.
I've had my Bose Ultra Open earbuds for several months now and use them mainly for listening to music during my early morning exercise walks. Also use them with my iPhone for phone calls. Before buying these, I switched between Airpods Pro and Bose QuietComfort earbuds. The open earbuds are the best I've ever used for my walks. The sound quality is excellent, clearly up to Bose standards, and the ability to hear approaching traffic has been a lifesaver.
Spectacular sound quality. However does not work with multiple BT connections. Even when Multipoint is disabled, Open Earbuds randomly drop one source and connect to another. I finally had to delete connections and just connect to a single device (android phone). Another annoying issue is noticeable time lag for audio to be heard. This makes it impossible to use any app where audio stops and starts - can't use Babel. So I just use them for music and podcasts.
My wife bought these awesome little headphones for me shortly after I first heard about them. I love them and use them very often. If I have one issue with them, it is that they are a little tight on the helix of my ear, no matter how high or low I place it. The sound is great and the battery life is amazing.
Excellent sound as Bose is known for, the eq section is awesome, my only complaint is my ears are huge, and they fit tight, but still comfortable, could be a bit louder, as I’m an older guy, with hearing loss, but I recommend them,
