After listening for only a couple hours starting with a full charge, it was already 3/4 drained. I workout every day, using light weights (12-35lb) to do a variety of HIIT, strength & endurance, and plyometrics exercises. The blue color is the same as a pair of light-medium color denim jeans and also looked great with light blue nail polish. Works greT! For me to pair to each device I have to unpair the other device. I bought this microphone to record covers for YouTube and SoundCloud but had some issues when recording my vocals into Logic Pro X as no audio was getting picked up from the microphone. I didn?t know they were the tiny kind of beads, but my daughter and I still really like them! Definitely will wear again and would recommend. Jims Review Room and Sound guys have a more comprehensive analysis that comes to a similar conclusion, but they do great, especially for canceling the low end. As others have mentioned, the small size, does get tiring on the ears after a while, but I find theyre find if I just shift them forward on my head a bit.
