Wonder if any one can steer me to a UK company that they feel they can recommend for Custom IEM's. Just had a bad experience with one in the UK, and now need to organize a new pair that will work, but am very cautious as a result . Any help or recommendations welcome. Thanks.

I start a new thread for discussion because the old thread was closed , I also own the Frogbeat C4 . Feel free to ask if you have any questions . Hope it can help everyone here ;))   LFF's Review ...
