DESC: Now anyone can afford GN Netcom quality, with GN 2200 Omega headsets. GN 2200 Omega headsets deliver professional performance at a value price, so you get a cost-effective solution without compromising sound quality or durability. You get style and comfort, too, in an elegant, lightweight design that's easy to wear all day long. Yet the GN 2200 Omega is durable enough to last for years, even under the most telephone-intensive conditions. The GN 2220 is the monaural version of GN 2200. It features a noise-canceling microphone and an extra-strong, ultra-sleek DuraFlex-II microphone boom - the first real advancement in microphone boom design since the original DuraFlex boom. To maximize the performance of GN 2200 Omega headsets, GN Netcom recommends using an amplifier to connect the headset to the telephone set or system.
