I’ve used 2,3 HD800 headphones from A4Tech. The sound and bass is really awesome and its the best bang for the buck in a gaming grade head phone gear market. The Problem with HD800 was its delicate design, nearly all of my HD800 headphones got cracked from the sides and finally went useless.
So on a friend’s suggestion, I went to buy a HD200, The design is pretty slick and it feels rock solid. The bass is also nearly as good as the HD800’s. Well its more durable than HD800 so i like it anyway. I’ve been enjoying it for over 2,3 months now.
But the issue i’ve faced recently is when i upgraded to Windows 7. The Dedicated sound control application for the A4Tech HD200 (Which is the same for HD800 headphones also) isn’t compatible with Windows 7, and you’re warned about this issue when you try to install the drivers/app for the headphone.
I installed the same setup with Vista Compatibility in Windows 7, and after a reboot, i was surprised to see the nice bass and sound again. Without it, the Sound is unbearable with generic Windows 7 drivers for the HD200/HD800.
The issue arises when you try to click and run the HD200/HD800’s Sound Configuration App (The application you get after you install the drivers from A4Tech) from the system tray. The OS hangs up for a while, then, you can move the mouse cursor only, but nothing else responds. Even alt+ctrl+del doesn’t work.
I hope A4Tech release a Windows 7 version of their HD200/HD800 drivers/sound configuration control.
If anybody knows a fix for this PC hanging Problem, please share.

There were some issues between the parties involved in the USB3.0 game back then in May, that could’ve possibly led to forks (and ended as a disaster, same as what happened to USB1.0). Now though, it looks like all the parties i.e. Microsoft, AMD, Dell, NEC have finally signed up for the new specs and all the forking issues have been resolved (through unknown negotiations probably).
