Foldable comfy bluetooth headset

I received these today and they are very comfy on your ears as they have soft spongy earmuffs.It paired quickly with my bluetooth on my phone.i listened to some songs on youtube and it was a clear sound.i then decided to check out the calling feature so i phoned a friend and asked him if he could hear me clearly and he could and so could I.there are buttons on one side of the headset which include on,off,play,pause,rewind,forward,volume up,volume down,fm/mp3 and answer/reject/end call/last number recall button.it comes with 2 cables a)charging cable b)3.5 stereo sound supply extension line.there is also a micro sd/tf card slot.It folds up so is handy to carry in your bag when you are out.The headset has a really good clear sound but im having abit of trouble finding the fm radio.It comes with instructions so I will persevere and im sure i can get it to work.lovely headset worth purchasing.
