The headset for my Panasonic-phone is an absolute must for me as a self-employed! So I can relax calls without dislocating my shoulder with the listener, and tap at the same time or whatever. The shelf life is due to the high use of not so significant. More than one year, it has still managed a headset. But given the price that's fine. The comfort of this variant is in contrast to the mini-plugs for the ears for permanent users is higher by a multiple. Acoustics are good. Loud and operate quietly. Muting must be kept manually, which I personally find better than a switch, because me this is often times fall accidentally into the silent position in the other models and so the talks ended abruptly.
