What owners love

4
  • Sound far better than the price and the 1980s looks suggest
  • Very light on the head; several owners wear them for years
  • Easy to drive from a phone, no amp needed
  • Some owners keep them alongside much pricier sets as a daily driver

The complaints

3
  • No isolation at all; open on-ear design leaks sound both ways
  • Build is basic; one owner says the Bluetooth version is poor
  • On-ear pads can get uncomfortable after a few hours for some

Where owners disagree

Everyone agrees they are a bargain; the split is whether an on-ear with zero isolation is usable outside the house.
