Once familiar with the button location and function, controlling volume, skipping tracks (backwards and forwards), and pausing and answering calls is very easy.
With no cables, there is no untangling hassle. We tested to around the three-metre mark and the connection was still strong.
Using Bluetooth does require headset recharging - every seven hours (claimed). We're up to five hours and they've not skipped a beat.
It's not exactly Bang and Olufsen sound quality, but certainly audible, even above the noise of rushing wind or turbo din - though our attempt at answering a call while going downhill wasn't successful; the caller couldn't hear us.
