Query: Great Sound, Pretty Good Battery Life

Having known Sennheiser's reputation for quality, I look for their products any time I am considering headphones. This model is pretty impressive, especially for the price. The sound quality is great, and the reception range is good. The only complaints I can think of are reception can be tricky to dial in once in a while, and battery life isn't fantastic. When compared to others, though in the price class, this is an outstanding product. The performance is only exceeded by other models much more expensive. In the future, though, I would like to see a model from Sennheiser that recharges via the stand for a few dollars more.
