Excellent headphones

Comments about Koss Bt540i Wireless Bluetooth Headphones:

These really aren't bad at all. I started off with a smaller pair of Panasonics and didn't like the range at all. It was very distant and tinny sounding so I started reading around. Something I read at CNET led me to get a pair of Sonys but I wound up sending them back. They were loud and bass'y but didn't offer anything crisp. I think if I would have spent a little more on Sony, I would have been fine, but I was led to these Koss by a review from POC Network ( ) who thought very well of them. They were the same price as the more expensive Sony option I probably would have ended up with outside of the fact that the Koss were wireless. I've never owned a pair of wireless headphone before so I thought hey, this would be cool. Well it was as I use them all over the place. I walk to work since I only live about 3 blocks away and tend to wear them there as well (when I can get away with it at least) ^_^. If they were waterproof, I would bring them to the gym with me and listen to something zen-like, but they aren't. I look back at the Panasonics and laugh :)
