Recently,just upgraded my headphone from Sennheiser HD201 to Audio Technica ES7.I think it is my best decision on buying headphone so far,though my real target is its bigger brother,the ESW9.Maybe next time,but to be honest,the Audio Technica vocal signature is the best one for me,maybe listening too much JPop?Got great price for them too,bought it at Jaben Store during recent PCFair.What impressed me the most is how different its sound(maybe my brain?) after 100hrs+ burn in.Its like it couldn't stop getting better each day passed.Never once I think I made a bad choice,though the comfort is really a bit turn off.Though its increase after done a little headband bending mod and leave it to my bear wearing them at night to increase the comfort.Maybe because I am wearing glasses and the supra aural design just a bit irritating to me.Nevertheless,it is the perfect headphone for me,except the comfort,which I am still trying to improve on.

Each person have their own taste,for my ear,the M50 vocal is not too close to you compared to ES7 and flat sounding with a bit more bass than ES7.I am looking for something fun also.Anyway,it is better not to have the feeling of upgrade,as your wallet will suffer.
