I have a friend that has the old R set - and they are good. These are even better. Superb bass, controlled treble, and they go LOUD. After having tried (and bought) a lot of the cheaper end of the Bluetooth headphone market, I can thoroughly recommend paying just that bit more and getting something that works and sounds brilliant.
Excellent little unit - and I do mean little. It's very small, but don't let that put you off. This is a great little device. My old transmitter used to get interfered with when I was only 4-5 metres away - this one works 10 metres plus. Recommended
