Very happy with these, have had them for a week now, came ready to use, pairing was very simple as is switching between devices. Got them primarily for cycling to work with as they allow me to hear the road clearly while enjoying some tunes. But since then have kept them on at work, as can still hear all around me while discreetly listening to music. they fit fine under cycle helmet, (and also under long hair) had to loosen helmet strap slightly but fine otherwise, am also able to wear shades over them too. did try the support band provided, and while it did as advertised, give a tighter fit, I found this wasn't best for cycling as you are lifting and twisting your head a lo so they needs to be a bit of give. Even so the fit is comfy an stays in place well when using around office or house. You do not need a high volume to hear things clearly and if you are in a quiet surrounding it will be heard by others if you do have the volume much above 25%. which is not an issue really. The battery life is great, have and them going for near enough 10 hours straight. if I had to pick faults it would be only that if wearing for long periods of time, 4+ hours the top of your ears can become a wee bit sore, but minimal and soon goes away once you take the headphones off. Very good bit of kit and very happy with overall quality and feel.
