I have the kind of ears that don't fit the earbuds, they don't stay in place even when I sit, let alone move around. I used to be skeptical that these headphones would make a difference, but I decided to try them out because I needed Bluetooth headphones since my phone connection had stopped working. They met all the requirements: They are lightweight, the battery lasts a long time, they have built-in controls and microphone, and they let me hear ambient sounds so I can wear them while hiking without noticing my surroundings. The battery lasts for over 10 hours of use, and charging is done with a regular micro USB cable. It comes with 3 adapters of different sizes so you can adjust it to your ears. I use the large size in one ear and the medium size in the other. With the clip that holds the cable in place, the headphones stay in place pretty well and don't get pulled around by the cable moving one way or the other. They do still occasionally fall out, but they seem to fit much better than any previous in-ear earbuds I've used. The audio quality is excellent, but these are not noise-canceling headphones; they are designed to let noise through, so you can use them in public places and still be well aware of the surroundings. If you're searching for a Bluetooth headset, you will not be disappointed with this headset.Also if you landed here it means that you like quality headphones and that's why i will recommend you http://www.thesoundexperts.org/
