The official "24 Season 8" CTU Headset: D

... Excellentes product placement for Plantronics, but also deserved for the current top model.
First of all: Even if "for professional office use" advertised that part belongs clearly in the car. The leatherette bag with integrated spare battery and LCD charge indicator is simply awesome and fits (zumind. In my Audi) perfectly in the tray next to the gear lever knob. A car charger saves you so completely and the headset at the same time has its fixed, protected storage location in the car. Call quality incl. "Noise Killer" is super, the wearing comfort thanks to in-ear and low weight excellent, pairing with different mobile phones (also Android smartphones) very easily and reliably. If the headset or spare battery but then again have the grid, ensures this in both cases, a microUSB port incl. The enclosed mini power supply.

Why then only 4/5 stars? Because the headset sometimes a bit sluggish responds to calls and commands, and Plantronics should at least offer an optional ear-clip for secure hold.

The bottom line is still the relatively high price absolute value and definitely hands-upper class.
