michaelk - I had (until yesterday) assumed USB as I'd had a lot of issues with the audio but it turns out that it was an issue with the connection on the PC and plugged into the screen it works perfectly. So, I was rather favouring the audio (mini-jack) connection. I have realised that any software the headphones require might be an issue on Linux hence favouring Razer. But I have to admit at the moment I'm edging towards an audio solution as I don't use the mic on my current (ancient) TurtleBeach pair.
Thanks for the reply - I feel reassured! There's a lot of conflicting information out there regarding Linux and headphones and I don't want to make an (expensive) mistake.
