I have a Razr mamba which I really liked. Note the last tense: the driver/management program causes kernel panic and computer crash on osx, and from what I've seen, fixing it is not on Razr's "to do" list.
I have Steel Series gaming headset which is really nice. The mic slides back in to the left ear so it's hidden and they look like normal headphones with an extra connection on the bottom. I haven't listened to any music with them as I needed something strictly for gaming that was comfortable and didn't suck.
I also have two Nagas and the Orichi. They're great products. I haven't met any other mouse that offers what the Naga does. If there was a blue tooth version, it would be perfect. The Orichi was ordered after my M.O.U.S. 9 that I bought turned out to be garbage. The thing would barely connect and sometimes work in OS X and it wouldn't work in Windows, which is strange considering that the company says it wouldn't be offering any OS X support. The Razer blades also look like a very well designed computer. I haven't seen one in person, but man, it's like the Darth Vader of the Macbook Pro like.
I think Razer makes great products and I've never had them let me down. So, they're definitely not like Apple.
