I really love my new headphones. I wanted a good pair of bluetooth headphones for travel and taking walks and these seemed to fit the bill. I didn't read all the features and was pleasantly surprised that it has a micro sd card slot for mp3's, an FM tuner and a 3.5mm cord so you can use them wired as well as wirelessly. I was also pleased with the fact that you can use them while they charge. The sound quality is great and has good sound canceling. I love how small they fold and that they came with such a nice carrying case as well.
