I like these headphones, I really do! Good mids, I hear things I have never heard before (Brand new - Gasoline) but I don't hear highs like my klipsch speakers. I know that isn't fair to headphones but I heard it it with Bose Airport and those are sopposedly a scam.I paid much lower then any Grado set, so I like 'em. They are portable and I feel like laughing at people who bought anything beats... But...these are not as high fidelety as I'd like. I may not have burn them in enough... but the highs are just not there.
If you're considering beats ... don't, these are better at cheaper price. If you are looking for a replacement to a king headphone setup, the m-80 will let you down... the highs cannot match the big boys
