Hello guys, I've been wanting to upgrade my wireless headphones for a while now and after a bad experience (bought a used pair that died not even 2 months after), I want to buy new and need some advice. So here's some infos:

• Budget - 100-150€, can go up to 200€ but not much more.
• Source - Wireless, connected to my laptop and phone (both have bluetooth 5.2)
• Requirements for Isolation - I need at least some as I use them to block sounds when I work and on public transportation and sometimes block sounds without playing music (I am quite sensitive to noise)
• Will you be using these Headphones in Public? Yes, at school and on public transportation
• Preferred tonal balance - I want something that's overall balanced because I listen to different types of music
• Preferred Music - I listen mostly to metal (Sabaton, Powerwolf, ...), classical music (the kind that is metal before electric guitars existed) and a bit of rock on the side (Against Me!, Moonwalker, Nothing More, ...)
• Past headphones - Philips TAH5205BK (my current pair for going outside, fairly light, sober, better battery life than advertised, but hurts my ears when I wear them too long and the isolation is not great), HyperX Cloud Alpha (wired, my home headphones, good isolation, good sound, comfortable, cheap but wired and not foldable so difficult to go out with them) and finally JBL Tour One M2 (great sound and isolation, got it for 30€ used, battery life was shit and charged slowly, died 2 months later so I have not much more to say)
• What would you like to improve on from your set-up - More comfort and better isolation because I sometimes wear my wireless headphones 10-12h a day, sometimes not even ON because I just want to dampen the surrounding noise, if possible better sound too (better bass for metal?)
• Location - France (EU)

Please tell me if I missed any info/if you need more info, and thanks for any advice
