I looked at the Plantronics Back Beat Go 2s with the battery case, before even buying the Bluebuds, but figured I made the better choice, among purely Bluetooth IEMs.
I used to consider the Sure 215s, but I hear things from both corners so, I'm not terribly confident.
I'd like to try the GR07s, but that's just out of reach, for now.
Possibly the Yamaha EPH-100s, HiFiMan Re-400, Etymotic hf5, other pairs similar.
I was pretty content with the sound on the Bluebuds and the wireless is definitely a nice thing to have, but I know I have room to improve with sound, and not being able to use them at all when they die is a bummer, especially when Android isn't supported for monitoring the percentage left.
