It might be a little wack to recommend you source in polish but here's a thread https://forum.mp3store.pl/topic/87462-polecane-s%C5%82uchawki-nauszne-co-wybra%C4%87-temat-og%C3%B3lny/
You can basically paste the list into translator and check out specific models, the best ones actually didn't change that much over the years. You can probably pick any from the "up to 250" (so like up to 50 quid for you) and get decent sound that won't get much better (with spending more money on headphones) unless you actually buy some audiophile setup.
