I do collect DJ headphones...just love it, have Senheiser HD 25 II, Senheiser HD 7, Auditechnica ATH 50X, XONE XD2-53 and having bought these TMA2 Dj Preset im quite dissapointed with the isolation for this reference (dont know if with another ear pads they might isolate better), along with the XONE's both of them have very poor isolation, as far as sound goes the sound is really good, punchy bass, at the moment the ones i have bought no of them beats the HD25's, ordered Pioneers C70s to also compare, will look forward to listen to Beyerdinamic 1350...as far as for DJ'ing they are like meeeh.
