I had this, audio-technica M50 and Bose QC15. After 2 weeks, I returned the other headphones.Bose QC15 was worst among these three for music. It was good only for noise cancellation.M50 was great sound for the price ($150).This is the BEST sound I have ever had. Both Mid range vocal and treble are very smooth and clean. Base is tight and precise. Unless you are in tight budget, you should get this one. Look no further.This is open headphone. The person seat next to you can easily recognize the song you are listing. This can be an annoyance for some people.I take away one star because of comfort. I feel pain after like 30 min of wearing this. But I still love it's sound and have to adjust it so I can wear it longer.
