First off, I didn't buy these heaphones from Play and I got them for a lot less than the asking price here.
That said, I honestly believe that they are still worth 35 quid, fast charge time (2hours for first charge) long lasting run time (around 8 hours) and good for handling calls.
They do not fall out of place in the gym or when I am riding rough terrain on my mountain bike. They feel slightly odd when you first wear them but you soon get used to the feeling.
The only negative I can say is that when connecting and disconnecting from calls there seems to be a high pitched bleep that is way louder than your current volume setting, ouch!
Overall a fantastic product and one that I look forward to using way more than standard ear buds!
