Cinema Mount Mark II audio cable extension

I asked support about the audio cable extension.

Specifically, I asked does it serve the purpose of the RODE SC7 or SC4 cable.  Their answer is an unequivocal yes.  I can use the supplied cable for that.
So I bought the RODE VideoMicro without buying the TRS to TRRS cable.
And you know what it does NOT work.  Apparently the male of the cable is TRRS but the female is not a TRS to TRRS receptacle.  Or that's just a faulty cable or they don't know what they are talking about.  A disappointment for sure.  I was hoping to use the iPhone and the Rode VideoMicro to shoot something tomorrow now I just can't even the eBay seller promptly shipped the order so I can receive it on time.  Alas, I'd have to shoot the Rode with my D810 for still and video now.

PS:  Now I suspect the audio extension cable is really just an extension for TRRS to TRRS only.  Why?  Because the mount is kind of blocked it needs a rather slim jack without the bulk so as to plug the jack in, if the TRRS is any bigger it won't be able to properly plugged in.

UPDATE:

I ordered the RODE SC7 TRS to TRRS patch cable.  And it works with the iPhone with or without the extension cable supplied with the Cinema Mount Mark II audio extension cable.  Like I expected you really need to use the extension cable as the opening is kind of small and even if you don't run the SC7 through the hold you can't mount the iPhone flat on the mount as like I said it's more like an enclosure and there is just no front room to accommodate the budge of the SC7 plug.  So again, the provided audio extension cable is just like what its name says it is an extension cable of TRRS to TRRS.  If you were to plug in a TRS it simply won't work even you can plug in everything.

After using the setup for a few weeks.  My initial assessment still holds true.  It's quite tiring to mount the iPhone.  It's difficult to access the mic/headphone jack, lightning jack, the volume control because it's more of an enclosure.  It's troublesome when one recorded a clip and wants to listen the audio using a headphone, you simply have to remove the iPhone from the mount to unplug and plug back the jack.  The tripod mount hole is on the wrong side, it should really be underneath the lens.

All in all, even without using the Beastgrip Pro, I think it's a better design, I would like the option of tightening the grip like the cinema mount mark ii and a lower price.  I guess I can keep dreaming.
