Urbanears' Hellas, a lightweight on-ear wireless Bluetooth sports headphone that retails for $119 (£80, AU$179) and comes in multiple color options, has a few things going for it.
First, it sits on your head securely, making it suitable for running or gym use, and is fairly comfortable for an on-ear headphone though it's a good idea to work it in a bit so it doesn't clamp down on your ears too firmly (the material on the earpads is slightly rough out of the box). It also has touch controls on the right earcup that work well. With a swipe of your finger you can raise and lower volume, skip tracks forward and back, and pause and play your music as well answer and end calls -- yes, the headphone has a built-in microphone.
Another plus is that you can easily remove the earpads and headband and wash them by sticking them in the washing machine. A washing bag is included along with a USB charging cable, and battery life is good at 14 hours.
And finally, the sound is decent. I like their sound better than Urbanears Plattan Wireless, which looks similar but has a different headband design and costs $20 less.
