Clip Sport Mono M4A Audiobooks Normal Speed plays in ONE ear only, both in Fast or Slow

Awesome… but a little awkward when clipped to my clothing while exercising, etc.  But, if I could find a plastic ended cable extension (converter from mono to stereo - one channel to both ears) that did this same function, it would give me a longer cable plus provide the ability to play my m4a audio in normal speed.

I wish Sandisk would look at this, and fix the fact that mono actually does work outputting to both ears in High or Slow speed, and make the normal playback work the same way.

I’m looking for something similar to Amazon item number 4330106031 with a flexible cable, maybe even 10" long that did the mono to stereo for 3.5mm.  I’d get it in a minute!

Thanks
