I just got the Sennheiser 595's and I want to say they sound awesome. I wanted a decent pair of headphones that I can use late at night to keep the house quiet while I'm on my Xbox 360. After some thought - and much reading I opted to go with the higher quality stereo headphones over a potentially weak sounding 5.1 headset. Admittedly I'm not an audiophile (I'll buy something without even listening to it based on other's reviews) but these do sound really great. I listen to a fair amount of music so I didn't want to sacrifice music for gaming.
I listened to several cd's this weekend and heard detail I've never heard through my HSU ventriloquists. I have an Onkyo TX-SR601 receiver driving them currently. So I do recommend them as well and I appreciate all of the posts helping me with my decision. It seems like anytime these days when you make a statement there is someone waiting to flame you. But I am glad we have a forum like this for the open exchange of opinion.
I also just got the Zalman Microphone and did the mod to the controller so I can use it instead of the cheap Live headset. The only thing I've done so far is to make a couple of audio messages to test it - mainly to check my soldering skills.
It seems to work fine but I had to hold the mic right up to my mouth for a decent volume. That said, the audio was very clear. As yet I haven't really had any online time to check out how the mic sounds to others. So I am curious too if anyone has had any experience with the Zalman - especially using it online.
Also I'm considering getting the JVC surround sound adapter but I really don't want to sacrifice audio quality for surround sound. I guess that's something you have to hear for yourself though. Can those with the JVC adapter chime in to say if they are happy with their decision to buy it?
