This headset that I use with my Uniden cordless phone and Samsung cell phone was a replacement for one by a different brand that broke. This one feels more solid and so far has lasted longer than the old one.Some reviews about this headset complain that the other side can't hear you or your voice is distorted when you're wearing this headset. There is a little 3-way switch on the plug that you're supposed to adjust until the headset works properly with your phone (I think it's a gain adjustment). When I first tried the headset, I called a friend to help me determine the best position for the switch.
