For heavy voice and music I get 12-14 hours before they die. Our mountain bikes with 2 and 2. When I first came across three I was like WINNER! The fact that I can listen to music and charge my phone at the same time is really amazing. Do not buy this cable if using the Arctis -- Horrible Quality. When the phone(s) are not charging and the charger is plugged in lights flash which is really annoying since I have this charger next to my bed. Its the only pair she has that does not make her trip over her feet. these rinse easy and are comfy on him! All in all we?re very happy with the earphones and they make a great alternative to the super high priced earphones like the AirPod. I followed the size chart and it fits as it should.
