We're supposed to be getting them into the store where I work, so I've been doing a bit of research. Apparently the Go2 (
click here) addressed all the problems the first model had (except the low battery life) and are apparently more comfortable based on the reviews I've seen.
This probably wasn't very helpful, but if you do happen to get them could you let me know what you think? I'm also considering getting them when they arrive in store, and unfortunately they don't allow me to test out products lol.
