Replacement for Ikko OH1'S

So my Ikko OH1’S left bud gave up on me. I’m looking for some advice really. I bought them from eBay as used but what kind of support can I get in terms of replacement from Ikko themselves?

If not, what sort of iems would you guys rec that are similar to the OH1’s but with more bass to them? Is it worth getting the OH10’s or is there another IEM that fits the bill?

TIA guys

Have you reached out to ikko? They could do something for you

I have, but tbh I’m not expecting much joy from it.

I’ve got a short list of

OH10’s
BQEYZ SPRING 1
TIN T4
SHOZY FORM 1.1
Blon 03
TRN BA5

what did you like and not like about them? anything lacking or too much of?

Lacking a little bass and the vocals could be more forward
