My HE-560s are on their last legs and I'm looking for a suitable replacement (not necessarily an "upgrade", just something similar). I love my HE-560s dearly, and with a little bit of EQing for increased bass, I think they're the perfect sounding headphones. Unfortunately the build quality is probably the worst I've ever experienced with a pair of headphones, and I've had to replace almost every part, sometimes multiple times. I've replaced the cable, the headband, and the earpads, and now the audio jack on the left ear cup is starting to die. The HE-560s are apparently discontinued and Hifiman said I should order a replacement pair soon if I intend to do so, because they are low on stock. I think I've spent close to $350 on parts alone, and a replacement pair would run me almost another $200. So what I'm really looking for is a pair of headphones that sounds similar, with the same amount of clarity and detail, and a slightly recessed/dry midrange. Are the higher end Hifiman headphones any better, in terms of build quality?
