I'd recommend against going with Logitech again. Having used logitech for many many years, I found that they only lasted about a year, some less than that. Their sound quality is fine, but no matter what Logitech I got (Gaming, Wireless, regular) they'd always break due to cheap wiring or cheap plastic construction.
I tried plantronics and they have much better cords than Logitech, but still broke due to cheap assembly and construction.
I'd highly recommend Razer products. Ever since I found out about them and have been switching my peripherals to Razer (Keyboard, Mouse, headset) I have yet to have a peripheral break. The construction is solid, the cords are wrapped to protect them and high quality, and the price is fairly equal to Logitech products.
I'm currently using a Razer Megalodon, one of the most sturdy headsets I've ever owned.
