Review on Poyiccot 3.5mm Speaker Wire Adapter: TRRS Male Jack to Terminal Block Balun Connectors Cable 30cm by Jeremy Lunn

The product transmits sound but is very, very quiet Very little sound comes out of the speakers listed by Revain even at maximum volume (product comes without connection instructions ) It's hard to say if this comes with It's related to the product or because of the sheer variety of different speaker types. Maybe one size doesn't fit all? Seems other users have had success. I haven't had one.
