Ergonomics, Build Quality.
Unlike the square shaped Lambda Frames, the Omega2 frame is circular. Most of the housing seems to be made from aluminum. The headband frame is a leather covered aluminum band, and there is a second leather band that will suspend the headphone on your head.
Wearing the Omega2 feels like a true high end headphone. The pads are made from sheep skin leather, and it’s one of the most comfortable pads I’ve ever tried. The elastic headband adjusts automatically to your head, and there is not the slightest sense of discomfort in the headphone. The aluminum frame has the perfect blend of pressure and elasticity, so you always have a good seal, but the pressure never feels excessive.
Perhaps the only other headphone that I can relate to in terms of comfort is the HD800. The design of the HD800 frame is very ergonomic, and I still hasn’t found a headphone more comfortable than the HD800. If the HD800 feels precise and lightweight, like a modern Ferrari, the Omega2 feels like old school luxury, more like a Bentley. In comparison to the Lambda frame Staxes, the Omega2 is miles ahead in terms of comfort, even compared to the SR-404 Limited Edition.
The pads are circular, and has a D-shaped opening for your ears. The pads are also thinner on the front than it is on the back, which puts the drivers on an angle to your ear. When I first received the Omega2 for this review, I couldn’t get a good fit, which really puzzled me because the Omega2 was really comfortable the last time I tried it. Turns out that the pads can be rotated, and D-shaped opening was positioned the wrong way. Once I set it right, then the headphone feels very comfortable on my head.
From Faust3D’s Wiki Page, I was able to find out that the first Omega2 variant, also known as the Mk1, was produced from 1997 to 2007, and the Omega2 Mk2 takes over from 2008 till today. Although the two variants seem to share the same driver, the Mk2 variant supposedly has a more prominent upper midrange. The Mk1 comes in two different colors: a champagne housing with brown pads & cables, and a champagne housing with black pads & cables. The Mk2 comes in an all black housing, pads, and cable color for the export market, and the same champagne housing and brown cables for the Japanese market.
Depending on where you buy your headphone from, it may be labelled as an Omega2, or an SR-007. There was also an SR-Omega (aka SR-Ω), which was introduced in 1993 and remained to be the flagship model until Stax went bankrupt in 1995.
