Thanks Mython!
Yeah that's what I figured. I'll go with the CCK and deal with the added bulk. This is temporary until I buy the Sony Xperia Compact.

 
So I picked up a CCK yesterday from the Apple store. Setup: iPhone (Spotify) > CCK > Micro USB Cable > Mojo > IEM. So far, I have run into 2 problems with this setup:
 
  • Reliability of CCK: When I tested the CCK at the Apple store as soon as I bought it, it worked fine. It failed to work this morning. Had to reboot my iPhone to get it to work.
  • Noise through Cable: I am almost certain it is noise through the cable. With the 2 devices placed even a feet apart, as shown in the picture below, I was getting a lot of noise. And to make it extra sure that, the noise was through the cable and not through EMI, I connected the Mojo to my PC and placed my iPhone, 0.5 feet from Mojo and there was no noise. Silver Lining though is that there is no noise if just the WiFi is on. So I am keeping my phone in Airplane mode and turning on just the WiFi to stream music on Spotify.
 
Sorry, had to use my phone to capture the picture. But you get the idea.

Thanks EW!
So are you going to try a new route? My main use for the Mojo will be for streaming Tidal.

Yes unsurprisingly we did thoroughly test this in our case design processes.


Well I was only giving feedback to people who asked for it to reassure them. I would have be surprised if you hadn't tested the case fully consider how long you put in its development.

Keep in mind, you can also download the songs for offline listening so that you can listen on the go in airplane mode. You probably already knew this, but just in case you didn't.

I own the L-19 and the Lavricable cable interconnect. Both work intermittently and require resets of the iDevice to make it work sometimes. The only full proof solution I have found to the Apple Camera kit is the Lightning Pure Silver Decoding cable from Penon Audio in Hong Kong.

http://penonaudio.com/Lightning-Pure-Silver-Decoding-Cable

Yes, it is expensive at $130 but it functions exactly like an Apple cable every time all the time. For over a month whether it is hard resets, soft resets, turning it off or iOS updates whatever it works perfectly. And before anyone asks and not to inflame the cable debate, yes it sounds materially better than the Apple Camera Kit.

This is exactly my experience.The L19 and the lavricable were both wonky. The http://penonaudio.com/Lightning-Pure-Silver-Decoding-Cable is 100% on the money!
 
I now feel no need to buy the Chord add-on for just the ergonomics. I'll wait for the next one:)

To decrease the charge noise, will plugging a USB Wall Charger directly into my UPS bring down the noise level the same as This?

Hello, could you help me, I want a nomadic headphones for my mojo and I hesitate between beyerdinamic dt 1350 and audio technica MSR7 . What is the best choice? Thank you

 
I use the beyer T51i (which are similar in design to the 1350) with my mojo, when commuting on the bus to work most mornings. I find that the Tesla technology is very good for jazz music, especially elements like the brushed cymbals. Some passages of music seem to float off the page, but maybe that is partly the mojo effect as well. The only downside is that sometimes the bus engine noise can intrude - I am liking the Tesla sound, and don't want to wear the full size Tesla headphones when commuting, so I have wondered about the AK T8ie, as an alternative mobile Tesla option.
 
I think that you would probably find the 1350s to be similar from a practicality point of view - sorry I have no experience with the MSR7.

i actually find the 1350 and t51p confusing design wise and tech overlap...so many people suggesting they sound very similar
...and even looks wise they're too close...i might be missing something (and sorry if i am) but imo beyer should get rid of one of the models.

You are right that they are so similar in many respects - I think that the key difference is that one of them appears in the 'consumer' range, and the other appears in the 'studio pro' range. 
For the studio pro, two key factors will be neutrality of sound, and are they comfortable to wear during a whole day at work in the studio. The consumer may only need the phones to be comfortable for an hour or so.

Is anyone of the Mojo's owner getting this kind of problem?
Awhile ago I accidentally plugged to charge my Mojo to the wrong female usb which is the one connecting to DAP instead of the charged usb. I did not pay attention until couple days ago I tried to charge the unit with the same charger I had before. My Mojo is getting pretty hot after around 15 minutes and the little tiny light did not turn off like before. I also tried charging with the external battery charger last night and after couple hours the unit is getting hot again.
All this time I have used with my Onkyo DP-X1.
The questions are it was my fault to shorten any circuits in the Mojo when charging the wrong usb? Or because I have connected to DP-X1 somehow it drains the Mojo battery so fast that can cause the unit getting hot so fast?
If anyone has experienced the same problem please give me advices what to do or not to do next. I appreciate your time and effort.

Little difference in price so take dt 1350 ... Some tests considers superior to 51 .

 
For me, looking for an entry point into experiencing the Tesla experience, the choice was between the T51 and the 1350. They are so similar, that I think the choice eventually came down to which was available for the better price - the choice regarding price can change from day to day, as new deals appear - but whichever you choose, I think you will experience great enjoyment listening to your music.
