Sweden-based Urbanears' Stadion ($99, £79 or approximately AU$140) is a bit of a different take on a wireless Bluetooth sports headphone, with a unique coiled cable that looks like an old telephone cord -- for those who remember what that is.
The idea is that instead of having any dangling wires to deal with, the coiled cable rests snugly on the back of your head with just enough tension to keeps the buds securely in your ears. They reminded me a little of Arriva headphones, but their coil is much tighter.
The Stadion, which comes in multiple color options, includes a few different sized EarClick tips to lock the bud in place, and one should fit your ear. The largest one worked for me.
Overall I was impressed with the fit, and while the design isn't not for everyone, I found the headphones worked really well for running and were comfortable to wear. They're sweat-proof and come with a nice carrying pouch.
As for the sound, it's decent though not exceptionally good. The Stadion doesn't deliver as much bass, detail or overall fullness as the more expensive, for example, but it's pleasant enough to listen to while you're working out. And you can make calls with it. Don't expect business-class performance, but I didn't have any complaints from the people I spoke to.
