I'm not sure about wireless earphones that has less than 20ms of latency..
I'm currently using kz zs3 iem earphones, bass optimized and fairly comfortable to wear. Maybe around 12 hours until I feel the strain on my ears. It has an optional bluetooth attachment you can buy, but I'm not too sure about the latency.
Anything that is wireless isn't very compatible to rhythm games and that's mainly due to latency. Instead, i'd suggest you to get wired headset. I got Turtle Beach Elite Atlas Pro Headsets and I must say that they are among some of the best headsets I have ever purchased.
