I am back into this thread, I just bought a used mojo.  It is dead quiet when listening.  I am very impressed with the sound.  My particular unit does make the squealing sound when charging, and stops once done charging.  It is pretty noticeable.  I know this was an issue with some of the units quite some time back.

What was the outcome?  Is it just something we live with?  Is it relatively all units, or relatively few units?  Is Chord replacing or repairing affected units?

Thanks all, I've been out a while, and the shear volume of this thread has become daunting!

Bro, try to use iphone ( 6 or 6s) charger to charge your mojo.most probably your issue will resolve... Becoz i use that and ... There were no any audiable hum or other noise... Cheers...

Is there a way to check the battery level on the Mojo?
I'm not seeing a way by reading through the manual online.

The LED colour below the charging port indicates the charge level when the Mojo is powered on. Blue is full, then green, yellow, red, then blinking red. When the light is blinking red run for the charger.

All this information can be found in the THIRD POST, including the the percentage range for each colour, under the Battery and Charging section.

Just noting there that my iPad charger generates a squealing noise in my Mojo. Other chargers I've used do not generate noise.

Don't worry about it if you hear the noise, Mojo is not faulty and will continue to be reliable.

Thanks all, I'll mess with chargers and cables as interest drives me, and otherwise not worry about it.

I am having great results using an F-1 XU208 DDC between my Macbook and Mojo. It seems to ameliorate a slight treble etch I was hearing when connecting Mojo directly via USB...

What's in the third post? I have read that people should check there for answers to their problems.

What is that ddc thingy? Noise suppressor type device?

USB/SPDIF converter. Connects to 3.5mm coaxial input on Mojo. Thread here; http://www.head-fi.org/t/803111/xmos-xu208-usb-bridges-the-latest-gen-has-arrived

Thank you. What would be the benefit of doing that? When would you use that? I was reading about it in the link you shared. I don't have a lot of time, so I only read the first post. I'll read more later when I am free. Thank you.

A little late to the party but I ordered mine today

Korg iAudiogate app can I connect to Google drive or
Dropbox may be stream Spotify?

iTunes refuses to sync files with a higher than 48 kHz frequency to an iDevice.  You therefore need a 3rd party app to copy and play the files.

I'm using Korg iAudiogate which was pricey but I got it on sale (50% off) and I'm quite happy with it.  I much prefer it to the atrocious iOS iTunes app.

Hi all,
 
Today D.A.R. is offering us IMHO,quite an objective article about why USB audio SQ may varies.

Cheers.

Hey Arpiben,

Just wanted to share this myself
I would like to add that it is damn informative an well structured... But maybe that's just me being a Darko Fanboy
But seriously it is an easy to read and understand article about USB Audio.
