yes a lot if our are using it on laptop or pc it leak sound a lot I mean if u listening at 20% of sound then also the guy setting next to you can listen the music clearly and at the full sound it just become a loud speaker. trust me I m using it and I have this issue in my headset.
Actually yes but only when you are listening at 40+ on pc. I don't go beyond 20 because they are very loud and 20% is enough to do gaming, movie etc. But i m sure you can not tolerate it 60%+ sound for more than 10 minutes on pc with 3d, virtual 7.1 on.
