TRN makes decent enough stuff and there's quite a selection available here (I really enjoyed my V90s until I broke them in my car door). KZ have a few popular reasonably priced models that you could look into. Blon bl-03 used to be all the rage a while back, you should be able to get those for around 20 bucks these days I think(?), an absolute steal (I had trouble getting a good seal with mine unfortunately, but that's my ears fault, not the earbuds).
