I bought this for my morphine juice pack, lost the adapter that came with. I turned out this fit better than my original one. But lacks in sound quality a little not by much like when you listen to some Bluetooth speaker. Seems little tight on female end, but no big deal. Make sure not to focus when you insert/pull. So far works well with iPhone earbud, beats studio, and my Audio Technica. Oh yeah delay respond on attached remote on both apple earbud and beat studio...\
