I'm not sure why this product is listed as 'Bluetooth Car Speakerphone', I suppose you could use it in the car but I, like most others, I suspect, bought it to listen to music on my phone without feeling like I've been wired up for some kind of medical test!
It arrived very quickly and was easy to set up. I think it paired with my 'phone on the second attempt. The ear-buds supplied are very comfortable and don't fall out. I like the one's supplied with my Samsung phone and these are the same, apart from the fact that the wires are the same length, which is a bonus as I could never understand why different length wires was useful at all.
The sound is good, there is no appreciable loss of quality due to it being wireless, in fact I would say there's a slight improvement over my 'fully wired' version.
The instruction manual is ok, but to be honest, after the device is paired and working, you won't really need it. The device hangs around your neck on a cord and also clips to your clothing with plenty of length in the headphone wires for you to wear anything you like, without being distracted by it, you just switch it on, pair up your 'phone and off you go.
Battery life is ok, the only thing I find slightly annoying is when you get the 'bleep bleep' warning that you need to charge it, you've only got a few minutes before it goes off, meaning that a couple of times I've left the house, got on the bus, and it's gone 'bleep bleep' then off, and I've got no headphones for the day, but now I'm used to how long it lasts (about 3 days for me, couple of hours use per day) I charge it up before that happens.
Overall, for 30 odd quid, very good quality product which doesn't make you look like you're wearing the latest electronic tag for your ears like some other bluetooth headphones. These are nice and discreet and sound great.
