Used for when im out running and their brilliant top class

Overall very reliable headphones. Clear music, easy connecting Bluetooth, surprisingly long battery life (must be about 5 hours if not more) and they come with a variety of earbud sizes to adjust. However, the red cord that connects each ear piece is much too long and comes with a teeny black piece to shorten it that is very easy to lose (mine blew off on a windy run on the beach). Regardless, they still work just fine without it; I just tuck the extra slack into the strap of my sports bra. The more irritating issue I have had with these is that the bit of plastic that loops behind the ear is much too big. I don't have particularly small ears (probably just about average), but this bit of plastic usually comes untucked very quickly and will either go into my ear lobe or just cause the ear piece to fall out. They require frequent adjustment to keep in place when sweaty as well, which can be impractical for exercise. This being said, I have used them for the past 10 months with only mild irritation and am overall pleased with the quality of sound and ease of use. The only reason I have stopped using them is that they went missing last week and have yet to turn up.
