right now im using a cheapo headset that i got along with my prebuild system about 4 years ago and i have them plugged into my new rig in a USB port(microphone/headphone prongs to usb adapter) and was wondering if i will notice an improvement going from this setup, to a sound card or DAC? and would it be worth going from this headset to a newer more quality built headset? so far a few people have complimented by saying that my voice is crystal clear when in skype calls/teamspeak compared to my friends with high dollar headsets but mine picks up EVERY NOISE in the background.
