Bitch please, surround sound
The A40's are great. Honestly when it comes to headset's it's either go big or go home for me. Never buying a $100 headset ever. They either have terrible crackling, poor quality, or just look ugly and are made from cheap plastic. Although I don't have these earphones I can say these are a great buy.
They look like they do have some weight to them, by that I mean they are not cheap. And the band that runs over your head looks thick, not some flimsy piece of plastic or something.
If money isn't an issue, they are a great buy.
