Very disappointed 267

At first I ordered the corsair pc in 1500 the sound was rather good on all but ecoutes ergonomics and finishes did not like so I decided to buy this Sennheiser PC 350 is to replace it. When I received the corsair was near for the return and fortunately I was able to compare the two helmet before making the return, well in audio quality there is no sound picture of corsair is very very front Loint suddenly I kept the corsair and returned the PC 350 there is 120 euros which separates the price of the Sennheiser is a foutage of mouth I'm a melomane when I decided to buy the stuff I am willing to pay but I want bang for my argent.Merci Amazon has for its customer service to top
