I don't know the difference in spec, but I recommend you to get the Sennheiser HD25-II... it OWNS!

Don't know how big of a difference it will be but I've only heard good things of the HD 25-1 II.

Never heard anything about the PX 210 BT, but the accolades about the hD25-1 II have been seemingly never-ending. If this is the choice, the choice is easy.

Ok and many thanks for that, going to get the sens hd25 1 11 then as yes they certainly look and sound great, i take it that these will be louder than the sens px 210 as they are only 107db and the sens hd25 1 11 are 120db, am i correct that they will go louder driven by a portable amp such as a ibasso td3 or fiio e7 ?
