You might get more useful responses if you post in 'Technology' or 'Shopping', rather than in 'Family'.
However it would help us to know whether you mean 'earphones' (i.e. the type of things where little buds are pressed into your ears) or 'headphones (i.e. the type of things that radio DJs wear). You've used both terms in your post.
It would also help to know whether you're seeking wired ear/headphones, wireless ear/headphones (which are supplied with their own transmitter unit) or Bluetooth ones.
Further, an indication your budget might help. Yes, I know that you've told us that you're seeking ear/headphones that "aren't expensive" but someone on a tight budget might mean 'less than a fiver' when he/she writes that, whereas a hi-fi enthusiast might mean 'less than a hundred quid' when he/she uses the same phrase.
