I bought the original HE-400 when they went on close out for cheap after being hyped on headfi for being so awesome. They sounded so disjointed and incoherent. Like if someone decided to build their first 3 way speaker by randomly selecting parts and picking bad Xover points. Maybe they were defective but I sent them back after a couple of weeks. then I went to K-701s. These were better, comfortable, but had no soul. I think I had an original Vali at the time and then a Lyr 2. I just couldn’t listen to more than a couple songs at a time. Replaced them with HD-598s and was a lot happier.
