The sound is truly great. You feel like you are inside the sound without playing the speakers at extremely high, damaging volume. Yet you can hear environmental sounds like people talking, sirens, etc. However others can hear your music as well and phone conversations are as public as a speaker phone. It is not a noise cancelling or privacy device and probably not for dorm rooms or airplanes. But if you don't like things in or over your ears and you want the best, fullest sound ever, this is a great choice. The sound comes from speakers located on the collar directly below where your ears would be when you wear it. It is quite comfortable, although I probably would not wear them jogging or working out because there is nothing to prevent the device from falling off your neck. But I cleaned house, walked around outside without any problems. I certainly would recommend for people who want sound quality above all else.
