That Is what is stopping me from buying the sennheiser momentum true wireless. The battery life is too low. They need to release a second gen with more features and battery life.
Have been following this thread for the last week or so and finally gave in (thanks guys and gals..I think) and picked up a pair of the MTWs at BB on my way home today. I've been using a pair of SE425s with the Mee Audio BTX1 cable and couldn't take the dropouts anymore (now I just use them in the office) so I was back to my Shure SE535 wired IEMs. However the more I read this thread, the more I miss having (somewhat) wireless IEMs. Just can't beat wireless for the daily 1 1/2 hour commute. My first pair of TWS and so far I'm impressed witht the sound (did not have high expectations). I did find the bass a bit bloated for my taste but sounds much better after some EQing. Cant wait to test out the connectivity during my commute next week
