It's been a while now since I've purchased those headphones. I appreciate them more and more since then. My previous headphones were high class Sennheiser and I was very hesitating going over to AKG. I don't regret it a bit. THose 2 brands are very different and still offer a high quality of their own. This model from AKG is very typical. The sound in general is so clear, so transparent. So clear that sometimes it can feel like it's emphasizing trebles and high-middle-register and a bit shy on the bass-side. Well in fast it's not really the case, those stay pretty true compared to the used source ( they're so clear so they made me replace my phono-preamp that I've had for years and was satisfied with but they allowed me a new comparison -level and I had to upgrade). We're used to boosted bass so those can seem pretty cold in sound-color when listening to them, but they're not, they're only pure, with maybe a slight slight tendenses to a bit wright sometimes but that suit me well. When listing to classical and voices they're amazing, the stage-picture is incredibly clear and pronounced, the brass sounds so real, the voice are very present?
Sometimes I miss the warmth of the sennheisers when listening to rock but I would NOT change back as the sennheisers today sound very muddy in comparison today when I'm used to those. To me they are the perfect mixing-headphones ( still very comfortable and relatively light for the size) and very very capable HIFI headphones, I would highly recommend them to anyone, very good price as well here on Thoman, worth even euro!
