In-helmet, speakers only. Recommendations please.

Shoei GT Air 2 so I believe 40mm is the size. Almost everything I’ve seen is for full communication systems and I just need simple headphones for maps directions and maybe the occasional podcast. I’ve seen a few things on Amazon but they seem pretty hit/miss. I’m using very small earbuds right now (pia but good enough) so if anyone knows of a bluetooth headphone set that‘d work, please let me know.
