Any confirmation that it plays well with iOS 10.3?
In reference to the Lavricable CCK replacement cable, mine arrived this morning, and after extensive testing I have found that sadly it does not.
iPhone 6s+, iOS 10.3.1, sim-free model (on T-Mobile), 128GB, non-jailbroken. Tested locally-stored music via Cesium and streaming Tidal HiFi.
After 20-30 seconds of playing, the "device not supported" message pops up and music routes to the speaker. Rebooting the phone resets things, but the error happens again.
Now, the lightning connector on the Lavricable is ever so shorter than the stock Apple one; just by the tiniest amount, but enough that it doesn't "click" when inserted, although the connection IS secure. So I thought maybe the problem was a poor connection, especially since I did my tests holding the phone and playing with the cable to test flexibility.
So, another reboot, and this time I plugged everything in beforehand, inserted the IEMs, and carefully started playing music without jiggling the cables. Same problem, 30-or-so seconds in and the "unsupported device" message popped up.
My final (and extremely tedious) series of tests involved the sequence in which I plugged things in. Cable to phone then DFR to cable, DFR to cable then cable to phone, etc. No difference any which way, always got the "device not supported" message after 20-30 seconds of play. These test were also performed with the whole setup on my desk and with no cable jiggle.
The only thing I haven't tested is using an Alesis USB midi keyboard and Blue Yeti USB microphone with the cable. Both devices work fine with the CCK, so I might get lucky and be able to dedicate the Lavricable to one of those. Edit: no go. Same exact problem with these devices, both on the iPhone and on an iPad Mini 4 running 10.3.1.
I will say though that the cable is attractive, well-constructed, and shipped VERY quickly (same day I ordered or the very next morning, can't remember which, but it was super-fast).
I just clicked on the link. It's out of stock!
I think you dodged a bullet there!
