[EX Q]: This should be more than an $18 speaker system. You will waste time and money.
[EX A]: Bad review

[EX Q]: I have purchased many headphones and ear buds from other manufacturers in the past. The only ones that worked were Monster cable brand. After my purchase of a pair of Turbine Ear Muffs for $300, there is no way I would pay anything close to $400 these things are terrible. They did not fit well on my head, they just hung off because even when you adjust them it still looked like your ears had an overfull muffer. It sounded terrible as well.
[EX A]: Bad review

[EX Q]: This is clearly a defective model if it can fail so quickly. I've bought two and had problems with both. After just six months my first pair died, but the warranty did have an option to get another pair. On this second pair, after only eight months, they're both dead. If you need something for office use, DO NOT BUY.UPDATE #2Well, I received the replacement set in July 2012. They now aren't working.
