Hey guys, just looking for some advice this time

what im after is a pair of headphones/earphones (would prefer earphones) that have quite good loudness, now i knwo that earphones are not really good for you but hey life is loud! Also i dont really have a budget but im not gonna spend £200

I have seen all these sound isolating earphones but dont really understand how good they actually are!

Could you guts give me some suggestion as what would be a good buy

Many Thanks
