Hello, Im an owner of a Brainwavez HM5 and I find it it outstanding. Im from Argentina and I bought it from China for 140 dollars last year. Now, I want to buy good headphones to my wife and Im considering buying this ones for her. Now, however Im travelling to the States in January so I can buy her headphones there. Are there better options than the Brainwavz HM5 for that money ?
