little over £100, but would absolutely recommend these

inb4 m50+modmic

.

Most people here will agree getting a nice pair of headphones + some sort of modmic/clip mic is better than a headset

BUT if you would rather have a headset here are my two recs:

HyperX Cloud Gaming Headset
Steelseries Siberia v2 (they may be scaling up the price on these since its one of the only things they make that people care about)

Both have great mic and sound quality (by headset standards) and are comfortable. I'd recommend the HyperX over the Siberias because the sound quality is slightly better and they're more comfortable.

The hyperx cloud is the only headset I will ever recommend not made by a company that also makes good headphones (at, senn, beyer, etc)

They're essentially takstar pro 80s with a decent mic attached

EDIT - also for my recommendation

get the Philips SHP9500 + a vmoda boom pro mic if you can deal with open headphones. the shp9500s are just as good if not better than the widely recommended HD598s imo

Can vouch for both of these headsets, I think the biggest difference between the two would be the cloud's microphone quality being surprisingly good for the cost and obviously being better than that of the Siberia v2s.

Modmic + Sennheiser 598/ATH-M50x headphone is a good option if you want to spend a bit more. But if you want to keep within your budget the HyperX Cloud 1 or 2 is also a good option.
