Salut.En qu'ingnieur as sound, and having read the reviews "CONSSO consumers" I do not drive the use of this casque.Un headphone headset and not a MUCH monitor mixing. I do not know ingnieur a sound worthy of not mix with headphones that "any brand" on the ears !!!!. It verifies the mix in the headphones, delays, rverbs the balances etc., but mostly we do not mix with, or is 90 sur100 chance to go straight into the mur.Ce headset is great, flattering trs in serious highlights reverbs "well Equalizer", good grain in mdiums, and pleasure in HF! If you want to please your artists, musician, singer, euse, producer, 7506 ... sony !!!!!, when an artist is cool in the headphone it will give the best of him .. and even what he's all of grace demande.Mais laissont headphones vocation Premire ...., do not make noise with his fucking And he is ....., l! but especially not mix with your monitors avec.Mixer "kind NS10M yamaha" or whatever, and listen APRS To check on 7506, but certainly not the opposite! To finish .. SUPER headphone warranty cost and pleasure of great singers in studio.Musiciens and / ravies.BETON keynote speakers, what else? SONY, You do not have a Walkman version? ???????? for the purists !!!!!
