These are for cycling (as I can wear with a helmet) and I hate tinny sounding headphones. These have good sound in the low range and the battery life is great which means I can do long rides and not run out of battery.
Best all round pair of wireless headphones I've owned.
They're the only pair that stay in my ears at all, and they continue to fit relatively snugly when running & doing all sorts of exercise. They're a little fiddly to fit at first, but once you're there they're comfortable and secure.
Good sound quality (not the best) but I'm pleased for the price.
