I don't recommend this headphones for bassheads, they have a bright sound perfect for rock or jazz. I specially enjoy its sound with live concerts.One interesting thing is that you can share the sound with someone, it has an extra 3.5 plug on the headphones

If you want cheap, good, and well made you can usually pick two. In my search for headphones, I compared these to the AKG K371 which was decently priced and good but had QC issues, and the Audiotechnica M50x which were good and well made but expensive. These are somehow relatively cheap, sound great, and are well made.

They are warm sounding but very fun. They look great and blocks quite a bit of out side sound
