OMG, I am not the only one, started having problem with tinnitus after buying BOSE QC35II headphones, I cant believe I am not the only one. I thought it is weird that I felt a lot of pressure and started feeling discomfort. And the reason I am here is because, after paying for the money for speakers that I love, I started feeling more ringing, with Old Onkyo Speakers this problem was not there, I feel 2k frequency is too loud as well on Klipsch - perhaps ? Denix8 could you please tell me what changes you have made to your lifestyle, it seems you are one step ahead of me for this problem - sorry to hear. .. Thanks for help!
