I received my 6110 Monday. Tuesday I tried very hard to convince myself to keep it. I even drove with it to GN Netcom's HQ and talked in person to their customer service people and repair department. Sadly, the unit does not perform well at all in my home environment, or in GN Netcom's lobby, or in my office. Its first problem is low volume when connected to a standard WECo 2500 phone. Even with all the controls cranked to their maximum settings, the volume is marginal at best, and not usable if the person at the other end is not very loud. GN Netcom's reply was that the unit was not designed to operate with standard phones, but only with &quot;modern&quot; electronic phones &quot;all of which have a volume control&quot;. The claim was that the FCC(!) limits the dB level they can put into your ear, and since you can't turn the volume up on a standard 2500 set, it's just not going to be very loud.I really liked the device, and still considered keeping it, but the other problem prevented that. There is a significant buzz on transmit, which bothers some people more than others. Some might just think it's background noise, but of course it's not. This noise was present when paired with the base station through my 2500 phone, when the base station was connected to an electronic phone we tried in Netcom's lobby, and is also present when using it with a D-Link Bluetooth DBT-120 and both a PowerMac G3 and a Titanium G4.As much as I like the look and feel, I'll be returning it to Amazon in the morning.
