The MUSIC STORE adapter has a 3.5 mm stereo jack socket and a 6.3 mm stereo jack socket. It is ideal for home use and fulfils all the requirements that are placed on it there. The good performance and workmanship make it the ideal choice for the home studio or rehearsal room.
Its a simple and portable 3,5mm to 6,5mm adaptor.
I had no trouble with it whatsoever, it works fine.
I use it on my Yamaha PSR E-343 keyboard because the plug is 6,5mm. Now I can "not disturb" others with my playing.
