Turtle Beach Stealth 600 TBS-3340-01 and Hyperx Cloud Stinger HX-HSCS-BK/NA-A
The best wireless options within that budget are the Turtle Beach Stealth 600 (the version that's Xbox/PC compatible is generally the cheapest, at least on Amazon), and the Logitech G535 LIGHTSPEED. Both should perform around the same as the headset you have sound wise, something that's better would likely cost around £100.
It’s a great headset man highly recommend.
Turtle beach 600 pc black is what I have. I've had them for about a year and a half not a single issue and they have a pretty good mic.
Mit meinem Turtle Beach Stealth 600 bin ich sehr zufrieden, ja es ist kein Astro A50, aber es ist deutlich günstiger und bietet einige funktionen die das astro auch hat. 2 verbindungsmöglichkeiten: einmal bluetooth und mit dem dongle. nutze es an der xbox series x und dem pc (achtung! es gibt noch eine version für die plastation) und kann mit einem knopfdruck die quelle ändern. im vergleich zum Astro A50 muss man aber abstriche in sachen klang machen.
If you can still get them (and if he doesn't have a standalone mic) then the turtle beach stealth 600 is great and usually less than £100
