I have a set of AKG K240'a and a set of AKG K271's (originals) and I'm looking into buying 6 sets of AKG K44's. I run a home based studio where I record and mix indie bands. In a studio setting there are 3 general uses for headphones and, ideally, you want 3 different types for those uses. Mixing/listening // Vocal booth monitoring // live room monitoring. For mixing and listening you want true hi fidelity, an accurate non-fatiguing sound you can reference from and enjoy. I'd never mix on K44's and that's not what they're for... I'd rarely listen to...
