But that's not the point. The point is headphone companies aren't even ******* trying anymore. Think of it like this, headphones are basically small speakers strapped onto your head. Do you know how speakers are tuned? Their housings are painstakingly tuned and dampened to make the frequency response as perfect as they possibly can. This requires the use of extensive acoustic dampening and tweaking. Headphone companies don't do this anymore. They just slap their drivers into an enclosure and call it good. Which leads to a slew of problems, like the HD800's massive 10kHz peak. Fostex is the ONLY one left who's actually investing time into damping their headphones (TH600 and TH900) to make them as good as they can.
Here's a challenge for you: name one headphone in production today, from any other company, that actually has acoustic damping in the earcups. One. I guarantee you can't.
If you're going to propose the Fostex over the HD800 for value and quality; we've got a serious problem. It's an amazingly nice looking product and fantastic closed headphone; but for that same reason, it's not quite as good as most competing open backs.
If I liked the TH900's that much, I'd buy them in a heartbeat. You don't even want to know what the mark-up on this headphone is, you'd be disgusted. It's the headphone we make the most profit with when we sell at our store.
