I am a business executive who needs ANC headphones for travel and for use at home. I also don't like to throw away?my investors heard earned money. After my last pair of noise cancelling Bose headphones (a gift from my wife) lost their ear pad and eventually broke, it was time for a new pair. I was looking for great sound, ear comfort, ANC and look? I was initially a little skeptical that Cowin could meet these requirements, but felt that I could always return them if required. My Cowin SE7 ANC headphones have exceeded expectations. I hope Cowin continues to develop and market high quality headphones! Buy a pair and you will not regret it!
