They sound well, but they arent the most durable ones, the plastic of the headband gets spoiled aftr 1-2 years like the plastic is degrading itself and the headband is hard to find, there are other headbands compatible but since they cost like 30-4' usd sometimes is just better to get new headphones, i won't recommend the HM5 as a buy, they sound quite well for their price, but the headband quality isnt good
SnidelI used to disagree with you, but since Fischer discontinued the metal headband, it is hard to recommend this. That said, I have had mine for a couple of years and used them extensively, and only the pads show any signs of wear.
The_JniacMine came with replacements for the cups, but the band has at least 3 cracks and now only duct tape holds it. Anyway, about the sound its quite neutral and for the price i agree i haven't tried anything better sounding headphones
SnidelSo is it the headband itself or the gimbals that break? You can get plans to 3D print the gimbals. I'm not sure if it is 100% compatible with the HM5, but you can get replacement headbands for the NVX XPT100:

JamieNZGimbals -they're made of a soft plastic that cracks over time. I've 3D printed them to replace my broken gimbals, but that's not a good sign that you need a backup plan before buying.
