Help. Purchased Mojo 2 and Sennheiser ie 900. Using iPhone as source connected to Mojo 2 via Fiio LT-LT2 Lighting to usb C cable.
I am getting quite frequently a lot of cracking and static noise . Is the cable likely to cause it( can mot att to m test with another one)? Or Mojo2?

Try cleaning out the lighting port.
Turn your phone off and don’t use anything metal.
It’s amazing the dirt and muck that builds up in a lighting port.

The USB connection on the Mojo2 can be finicky. When using it with my iPhone, I have to power up the Mojo2 first, then connect it to my iPhone. Otherwise, yes, I get massive distortion. It could be the cable, but in my case, it's the order of operations. Seems to be persistent quirk with the Mojo2's USB implementation.

Been looking for a 4.4mm adapter for my mojo 2. Can I use any adapter without damaging my mojo in any way or is there anything special about the custom mojo ones (other than matching looks)?
My only hard criteria is that it only uses one 3.5mm port. I see that the PW Audio and DDHiFi D44MOJO ones use both, which looks better, but I value having two available ports more. Looking at the DJ44CPro at the moment. Ideally it would be straight though and not triangular like that one. Which do you use and do you recommend it?

Nothing special about a 3.5 SE to 4.4 balanced adapter. It's straightforward. But IMO even a simple plug-style adapter is fairly expensive for what it is, so I just picked up the better-suited ddHiFi adapter for an additional $10 over what most plug-style adapters cost. But that's just about looks. It doesn't do anything different from any other SE-to-balanced adapter.

Thank you very much. Following this order works also with me. Didn’t (touch wood) get any static in the past hour!

This is what I use. It does seem to be hard to find.

I have got these from aliexpress on 2 seperate occassions from 2 different stores (I've tried to find my emails, but cannot, it was a while ago) & both are great & were cheap but well made. There are lots of choices on the website. Just be cautious that you double check that it is 4.4mm female & 3.5mm male. It is easy to mis-order

Successful install of new battery. Working beautifully now.

These look identical to the battery in the Mojo 2 so I suspect it's the same factory Chord use. Plus they sent two!

I am curious about the Poly. I assume this also has a battery?? If do do we know what kind that takes?

I assume (a lot of assuming here) that the Poly is using the Mojo battery while connected to it but it does still have its own?

Would be nice to change that if possible as well if so.

Cheers

Poly has its own battery. It doesn't use mojo's battery.

Thanks again guys

It does suck from mojo battery.

 

[turbofeet]

Yes thanks guys. I found one on Ali Express. If it works I'll share a link.

Not really.

Poly constantly polls the mojo for activity, but it uses it's own battery. There isn't evidence to suggest that the poly battery is supplemented by the mojo battery or vice versa. The light that you see on the poly for the mojo is a passthrough light tube to see the charging state of the mojo.

Although I did not test the actual USB connections directly, I did just try the following:

Boot the Mojo2+Poly
Disconnect Mojo2's battery
Mojo2 shuts down immediately.

Pressing the power button does not start the device.

Plugging the Poly into a power source, with Mojo2 connected and without battery connected, boots the Mojo2 immediately.

As such I believe the Mojo2 not to use the Poly as a power source.

Also while i'm at it:
Poly uses an LP113452 2100mah battery
Mojo2 uses an "DJ electronics" lp133273 1850mah battery

Because of the enormous size difference, and the bigger battery being lower capacity, I believe the poly battery to be less than 2100mah

Disconnecting both batteries and plugging them into a power source does boot up the Mojo2, but the Poly remains off.

Having the Poly battery disconnected, and the Mojo2's connected, will not boot the Poly, unless a USB cable is delivering power, and Mojo2 is turned off first. Then the Poly will give a white light, and after that you can start the Mojo2, together with the Poly.
