I'm going to be upgrading from my Plantronics Gamecom 780 headset, and I'm not sure what to get. I'm thinking about getting the Sennheiser PC323 as they seem to sound good and have a decent mic, but a lot of people are saying that it would be better to get some proper headphones and a mic. The headphone and mic solution would cost a lot more most likely, and I am wondering whether there would be a big quality difference between the PC323 and proper headphones. I will be gaming mainly, but I will also be watching movies and gaming. What should I go for? Any help is appreciated!
