I've been using it for a month now and am very impressed. I work around high pitched electronic popwer equipment and was able to talk using the headset without the caller hearing the noise of the equipment. My phone is an LG VX8100. I sometimes have to use the phone to connect to the headset but this only seems to happen when I have connected the headset to another device.Had some problems with the volume when using it with the other ear piece to listen to music on an MP3 player. The corded earpiece volume was noticebly higher, connected using the graphic equalizer software and was able to correct the balance.Using a Zoom bluetooth dongle plugged into a Dell Laptop, could also connect the headset and use it for VOIP calls using Skype. Oh the freedom of being without cords!
