so after using these for 4 months they have been awesome, the sound have been awesome apart from a lose connection on the left headphone which was easily fixed, I got these for £220 from richer sounds which may sound a lot of money but the sound is amazing the bass and the treble have an amazing effect from my htc m8 which i think is the best phone for sound quality.
 
Just ordered the Audio-Technica ATH-M50x to compear  these with, after compearing them with the beats and sony for the same price range.
