got HD650 it is really good for what i need yet one big problem is they do leak the sound that even the one who is outside the room can hear it, i listen to music on the PC with 52% vol and even the player is 50% too! and the amp/dac less than 50% still this massive leakage.
will the TH900 solve this problem? also from reading i know that the TH900 will serve my need of music so for now i need to know about the leaking level.
The TH-900 have a closed back but they still leak a little bit of sound because they have a vent/gap around the cup which lets air in and out.
