still waiting for full burn in. But on first try you can immediately feel it is much more comfortable than the piston v2.1 that I had. Ive been using it for gaming most of the time BF4 and BF Hardline(ada sales on origin ma) Can feel the bass wise slightly if not better than the piston v2. As for songs I mostly listen to ballads. But I would give 10 thumbs up for the comfortabiliy of it compared to Piston v2.1. I can easily wear it for 2-3 hour straight without feeling uncomfortable and also the noise isolation is much better that the v2.1. I'm not sure about others but my v2.1 feels unbalaced (right side if fully seal but left side prone to more sound leakage even with 2 XL size one its the same.) Overall quality I would definitely recommend the v4 over v2.1.

hope that helped a little. ^^v
