I bought the Logitech G933 Artemis Spectrum in late 2017. Around July-August I began having issues where audio wouldnt come out the left ear cup. It appears it had something to do with the power button since if I played around with it it would get fixed. Eventually is was just a hassle and I filed an RMA and got a new set around September. The replacements worked fine until last week. Went out to eat and when I came back no audio from one the left side, at all. The right side gave away that same day while troubleshooting.
I ordered the Sennheiser GSP600 wit the GX1000. They sound ok I guess, not worse, but they didnt blew me away compared to the G933 (I cant directly compare since Im still waiting on Logitech; their support is so slow).
I have always read of ppl saying to skip gaming headphones and just get a headset and mic so Im thinking of returning the GSP600/GX1000 and buying the Sennheiser HD 660S which get alot of great reviews. Would they sound ok connected to my ASUS Formula X or do I need a DAC/AMP combo? Any recommendations?
