After 3 months of use I can say the Ultra Open Earbuds’ sound/fit/comfort are all great. Battery life Is…ok. Luckily they charge relatively quickly. The Bluetooth connection (iPhone 15 Pro Max) has been terrible. I lose connection to one earbud pretty often with PiP. The app will also unpair randomly, so I can be connected in phone settings while listening to something, but the app will report a failure to connect. I’ve been through all the recommended steps to resolve without any improvement. That said, I didn’t have any issues until the latest firmware update, so hopefully that goes away soon. I see the UO Earbuds as the more convenient and discreet evolution of the Bose Soundwear, which I still love and use …while my buds charge. Overall, the concept is awesome and the initial execution is promising but leaves me wanting more. I hope Bose expands on the UOE and delivers a polished 2nd gen.
