I bought Fiio BTR5. I was using those with my Blons + KZ ZSN Pro for quite a while, then I bought a QCY T13. It sounds like 20% less good (Ofc KZ have better soundstage and bass), but the clarity was greater than my Sennheiser HD 4.40 BT (Not a tall order, imo), so I end up using QCY faar more often.
I still use Fiio BTR5 as a bluetooth adapter to connect my iPhone to my speakers (Some 2.1 speakers I bought in used in Sweden for 800 INR lol. It has recessed mids but decent bass and is loud enough for casual listening).
