Thanks for the answers.
My rigg is in a seperate room and I don't have to worry for any neighbours

In my downstairs living room I have a great 5.1 (B&W speakers and Yamaha subwoofer) and a pretty big Sony Bravia LCD.
Tried the PS3 on this combo to see/hear the difference.
As Tomcat66 said: don't expect too much from GT6 in the sound department ... he is right. It was absolutely a lot better than the effect of the small LG speakers, but having the rigg in my living room was no option.
Even tried it on my Sony Bravia (without the 5.1 sound system) and even that gave a noticeable difference.
So because the speakers of my (game) LG tv are rather poor, I was looking for something (not taking too much space) to enhance the sound somewhat. I listened in the shop to some (Sony, Samsung) soundbars. Not bad, but a lot of money for what they really did.
Then i stumbled onto this Vibe thing: relatively small, one cable, no extra amplifier, mounting under the seat is possible (maybe you could feel it then ?), not expensive.
But until now I found no way to listen to the thing first (no dealer or shop in Belgium), that's why I was looking for some feedback by owners. Nobody seems to be using it though.
I also had my eye on this Logitech set:

Have not had the chance to listen to that one either...
But I don't really like all the mounting bars, especially the one to the headpart of the seat.
As for a headset: tried it, was great for 15 minutes and then it began to bother me... don't really know why...
