Is there a small nuclear power plant in there or what?

By comparison, I got the thing in the week determined 4-5 hours in the car on the ear. Charging? Perhaps every 2 months !!!
No idea how this would work.

The functionality is very simple. No frills. On / off / volume / acceptance button. But goes well with two phones. I do not know - I do not use

What is also great: When I have the part in your car not to the ear and it calls me to someone, then I take it quickly out of the storage compartment Turn it on, and until I then turn made it to the ear (goes fast) I can even accept the call via the headset. May take 3-4 seconds until it has connected ...

It always says "Power on - Battery High - Connected" And it really says is almost always "Battery high"!

And the sound (I imagine there but frankly zero claims) is in my opinion very well.

Something there is certainly more expensive. I wonder what.
