I have long worked with a relatively neutral closed headphones (Sony MDR-CD270) ... so I did not have the impression of hearing the bass, midrange and treble redistributed with this semi-open headphones AKG K702 .. . by against I clearly gained momentum and clarity! Now all the subtleties of a mix of a song or orchestral music are clear! The restitution accuracy is diabolical! The ears are not flattered ... they are just perfectly nourished! I tested several models before it, including some that were heavily loaded with serious ... and I admit that this neutral and respectful listening is a delight for the ears (like I ask the bypass to my calibrated monitors, I am demanding, I work in the audiovisual and cinema). The helmet is relatively light (I feel absolutely not, it is very comfortable), the finishes are really neat, detachable cable is a real plus compared to K701 (I destroyed my old helmet because of its integrated cable and jack I could not easily shake off the computer). At price / quality it is hard to beat (the helmet was proposed to 210 euros on Amazon at a promo, still I paid a little more than the Q701 which also has a detachable cable .. . but I prefer the design of the K702 few dollars difference ... to avoid the green stitching and the "Q" on the ears ... and see 10 years - at least I hope - on my table while beautiful, in harmony with my machines ... it was worth it! ^^).
