[EX Q]: This is an excellent product. It replaces a unit that broke after some time. The old one had the battery door open and needed to be recharged. You need two AAA batteries. It's lightweight - good to travel with. Batteries can last 2-3 weeks between charging. All in all I'm very satisfied with performance - no complaints.
[EX A]: Good 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]: For the price, you can not beat this battery pack and charger. You get 2 batteries, a charger plug in unit, charger, usb cord and wall mount. The batteries charge fast, but hold their power very long. I have charged them both 3 times, sometimes all night if i don't use them.
[EX A]:
Good Review
