Hard to tell! I can only seem to get 45-60 minutes of earphone use at a time before charging and now only the same time! I then get two beeps for several minutes at a time and then they no longer work. I believe I used to watch a 3 hour football game with them, now still only the 45-60 minutes before having to re-charge them. What's up with this?
