After going through several cheaper bluetooth speakers, we couldnt be happier with this one! There is no latency that I have ever noticed while using it and battery life is decent, with the lighting off the mouse battery life improves greatly and I have been using it like that for a bit for the extra life, however it is very convenient to use the charging dock to charge with when Im not using it and the charging dock looks very nice when lit up. Use painters tape if youre worried. I would not expect this OEM product to fail as others have suggested unless Sennheisers overall quality has diminished. The batteries have lasted longer than I need them every time. If you?re lucky enough to have narrow feet then get these, they?re a nice mix of dressy, casual, and sporty. I would definitely buy this again App, so I saw a lot of people mention you cant connect the headset to the app. These are perfect for guests that are unable to bend and need their suitcase to be lifted off the floor. So when it came to working out, I would never wear my airpods to the gym for the fear of losing them while lifting.
