Func's KB-460 Mechanical Keyboard Hits Shelves
Func's KB-460 is a mechanical keyboard that is remarkably simple
Func has released its new keyboard, the KB-460. This is a mechanical gaming keyboard that is built around the core principle of simplicity and functionality.
It features Cherry MX Red switches, which have a travel distance of 4 mm, with actuation at 2 mm along the way. They are also linear and need an actuation force of 45 grams. Beyond this, the keyboard features red backlighting, along with a large integrated aluminum backplate. It also comes with a wrist rest.
Other features include Func mode, which disables the windows key, driverless operation, built-in 128 KB of memory for storing profiles, as well as integrated media controls and a two-port USB hub.
The keyboard's MSRP is set at $119.95, though as a launch promotion, Func has temporarily priced it at $99.95.

I would pay a lot of money for an MX Red keyboard with customizable buttons or at least extra buttons... If any
I think the brand was bought up by some other company, that company may be Swedish. For some reason they replied to my mail in Swedish at least.
It's got the exact same body as the Leopold I'm typing on right now. It's missing the detachable cord, but other than that and the larger enter key, it's identical. Should be quite a good keyboard.
A lot of us have audiophile headphones. The solution to that is to buy a headphone amp... which you should have if you have high resistance headphones anyways.
As for volume buttons on the keyboard, look at what I said in my last post about AutoHotKey. I'm currently using insert, home, and page up for previous, pause, and next tracks, and end and page down for volume up and down. Works a treat, takes virtually no system resources, and loads with windows.
As for your keyboard being loud, buy rubber spacers. You'll have to take each key up to put the spacers on, but the noise will be deadened. It won't be silent, but the noise won't carry NEARLY as far.

15 dollars and the best "response" you'll receive w/ a window key (the old IBM Keyboards being the grand daddy, but lacking a windows key)
