Perfect product for Keyboard/ Synthesizer
Product fits perfectly to my son’s keyboard..Build quality & looks could have been better but at this price range it solves purpose. Connectivity is good no loose connection.I have tested this on Yamaha i400, F51, Casio CTK 260in & headphones like Boat Rockers 550 and Zebronics. I could connect keyboard out out via my Aux to home theatre Sony TZ145. Sound quality is good..

Well made, fits firmly.
The Adaptor plug is well made, fits firmly and snugly. Once inserted, the headphone jack sits tight and does not fall out. The Adaptor also fits well in my Onkyo TX-NR676 headphone socket and works perfectly.

This pin does not fit at all even push with force in Casio ct870in.
