Have a very old set of Sennheiser PC360 that is slowly falling apart and it's time to replace them. Currently have a Z170X-UD3 with Realtek® ALC1150 motherboard. It also says in the blurb it has a built in amp. Don't need a built in microphone. Prefer the big, cloth ear pads of the Sennheiser over smaller leather ear pads. Would like a replaceable 3.5mm cable into the headphones. Prefer open back, noise in/out not a concern. Not fussed about inline controls. < £200 budget. Won't actually be used for high end audio, will mainly be for general PC use, spotify, games, videos etc. I was looking at the Sennheiser HD599, I assume the onboard audio/amp is enough to drive them properly? Cheers.
