The 15ft Grado "branded" headphone extension is $50.00. Grado advertises no degradation in sound quality. I bought this coupler along with the an extension(Cab-4791-All)—total cost about $17.00—and this solution also provides zero degradation in sound quality. I like getting the same results without having to pay for the branding! 5 STARS!!!

Good quality.

Works perfectly, a must have adapters and accessories for our Church's AV team.

excellent

Great connector to extend my old school headphone listening distance. No hum. Connections snug..

This is good enough for gigging with. Works well. Very hand when you need just one.
