  • +Great value

Cons

  • โˆ’Inferior to susvara
  • โˆ’Can seem bland compared to 'party trick headphones'
  • โˆ’Isn't even going to be available new anymore
  • โˆ’Ear cups may not fit large ears well
โ€œI've had mine for a few years as well, and I love them. It's so good that makes well made music pop a lot more... I replaced my HD6XX pads recently with these and they've been great.โ€
