CNET has a review of the Gennum nX6000 and writes – “Although we were mostly pleased with the design of the headset, we couldn’t help but find the controls a little awkward. Like most Bluetooth headsets, you have to press the multifunction button in certain lengths of time and listen for a certain tone depending on what function you’re trying to perform. However, the nX6000 seems a little more time-sensitive than most. For example, the difference between ending a call, muting a call, and putting a call on hold is about one to two seconds of button pressure between each step. If you’re a second late or early, you might end up performing a completely different function. We did finally learn how to time our button pressing, but you should read over the user manual to get the hang of it.”
