I own a number of bluetooth headphones and use them for various things (gym, walking, work, music) This is the first pair that seem to tick all the boxes in one pair. First and foremost for me is that they fit really well, I have trouble finding ear buds that stay in my ear and are comfortable to wear , these do that in spades. there are a number of different size and style wings and I found one that works a treat for my ears. The sound is great for music but more important for me is that they work really well for phone conversations. I hate it when the person at the other end of the phone keeps saying I cant hear you and you have to take out the ear buds. With these ones my wife actually asked me if I was really using ear buds as it was soooo clear she though I was kidding her. Having a case that gives multiple charges and can be used as an emergency charger for my phone is a serious added bonus. If you buy these I cant see how you could possible be disappointed, particularly at the price as the seriously punch above their weight.
