works simply and well with iPhone 4S

I have the headset for a few days now in use and could not, even though I had never previously one, without using manual immediately!
The coupling ran easily automatically. Bluetooth on, connect, ready. I can hear in the whole house my audiobook to annoy others without. The range is great.
Since the strap is very thin, I can wear it even with glasses, without pushing. The sound is very good at music and audiobooks are not tinny. Also in the car the sound and the volume is perfect. Now I can my FM transmitter dispose.
The only mistake I made at the beginning, and what a Nachlesens needs: the on / off switch is over the button, which prompted then pressed if mattering that the last called conversation Spartans will be called again. One can, however, if you know it, avoid any problems.
Got I have already recommended this headset and I am glad such a quality for this price!
This headset absolutely deserves full marks!
