Siemens Gigaset SL400A


Fantastic build quality; aesthetically and ergonomically pleasing

I bought this unit specifically because it has the capability to connect with a bluetooth headset. When I use the headset, the other person is not usually able to hear me despite me turning the mic volume up to its highest level, which is very frustrating
