[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]: I recently received a Roku 2XS so I could cut my cable service. The device is very easy to set up but the setup disc did not work. It would ask for authorization several times before it allowed me to. After 2 hours, and lots of frustration, resetting all settings as if on the tv screen, etc. finally finished with just using the TV remote.
[EX A]: Good Review

[EX Q]: I bought this for my wife's car that doesn't have a cd player and the cassette player. It works but you must keep making sure it lines up perfectly or else the sound becomes distorted. The product itself is OK though.
[EX A]:
Good Review
