[EX Q]: For some reason these earphones produce an almost constant buzzing when I have them on or turn the volume up. Even at max volume. Very annoying. I've gotten two sets of those cheap chinese junk ones. They're worth it to spend just a few bucks more. You get what you pay for. Spend your money wisely folks. These are a total waste. I'm very unhappy with this purchase. Don't waste time and money. Get something good. That's where I've ended up now.
[EX A]: Bad review

[EX Q]: You have got to be kidding me? These look so cool but when you receive them they are not at all what is was pictured as being!!! I'm very disappointed!
[EX A]: Bad review

[EX Q]: The sound is great but the bass is lacking. I find that when listening for more then 30 minutes the top portion of my head will burn from ear pressure. Other headphones I've owned are extremely comfortable and offer very good bass. You can still hear other noises at full volume though which makes me a little irritated as I like to have private time while listening. These go back in less than an hour. They do look cool if you aren't overly concerned with their comfort level.
