Chord Mojo(1) DAC-amp ☆★►FAQ in 3rd post!◄★☆

[magicalmouse]

I bought a replacement battery from China which worked fine for three months and then died, i have contacted Easylander but (as yet) have had no reply and their messaging system doesn't seem to have anyone answering it and there seems to email link.

So I have removed the battery and found it works ok through laptop usb in place of an internal battery - i am using oppo pm3/meze 99 (modded)/hd25 (modded) and etymotics.

. . . . an external power supply at 5V . . . .

Do you mean, you used the standard USB charger port
OR
did you connect a 5V external supply directly to battery terminals/circuit board ?

Standard usb. I use the iPower 5V power supply, but anything works. I’ve had noise with other power supplies though

LiPo batteries can have vastly different lifetime depending on treatment.

For lifetime you should:
* store them at app. 30% charge state (never store them fully charged)
* avoid high temperatures in operation or storage (both reduces the lifetime)
* ideally keep them between 20% and 80% charge state

There have been so many reports about early aging and death of the Mojo's battery that I want to share a different experience with my Mojo, bought around May or June 2018.

After giving it a full charge over night I tested it and got a whopping total of 6 hours 50 minutes runtime over 2 days at red volume setting with IEMs! The first 2h were with Coax, the remaining time I used it with USB from the computer. This is still on the original battery, but I did try to follow the rules of battery care stated above, usually not fully charging or discharging the battery, and especially avoiding storing the Mojo with fully charged battery.

And I got one from Alixpress for $20 or so, after few months I am getting 6/7+ hours!
That is in blue or purple volume, USB input driving my large Planar headphones (Hifiman Edition XS).
mojo battery issue is overblown in my opinion.
Use it as is, or get one from Ali-x , they are cheap enough - even original from Chord cost me no more than £45.
Hardly an issue.

Cool - the battery issues were very significant for me. If you are not located in England, then you have to find a distributor to get an approved battery. I tried an aliexpress battery and it had serious issues - nothing I want to lose a $500 device for.

What were the issues please? I have an aliexpress one and so far so good but would like to be prepared.

 

[utdeep]

Low battery life - then it bulged

My Aliexpress (easylander) stopped charging after 3 months and i have removed it and am using mojo powered by usb from laptop and/or portable battery pack

Can you run the Mojo 2 off a USB power supply without it destroying the battery life and will this affect the sound quality at all?

I've also found some nice 4.4mm female to 3.5mm male adaptors. These would supposedly allow me to run a balanced cable into the SE 3.5mm inputs. Of course it won't be balanced but it will just work as if it were a 3.5mm SE cable. Am I right?

Yes the adaptor will work fine. Most of my headphones and IEMs are terminated with balanced connections and I use these adapters to use the Mojo's 3.5 SE output. Enjoy!

Trying out the siblings.

It's interesting as I have seen reviews mention Hugo 1 is close to Mojo 1. Definitely not seeming that way on my Focal Clear, Hugo is a much nicer listen, it feels far more spacious, subtle, and less coloured. Still love the Mojo for the on the go, but it's interesting to see what the next rung up is like, or rather few rungs, at least if you're a Mojo fan like me. It was my first good DAC!

Hi all, I would like to share how I upgrade the Chord Mojo to have Bluetooth Receiver and USB C Connector.

As suggested by the previous post, I use XDuoo 05BL Pro and create a 3D printed casing for the PCB and Batteries. The result is something similar to Chord Poly, but smaller. After the upgrade:
- Bluetooth receiver up to LDAC, auto quality is very similar with direct DAC
- Media control button
- USB C Charging port for both XDuoo and Mojo
- USB C DAC port for Mojo

The CAD file for the casing and the step by step is also being shared under this blogpost link. Please do give your comment or suggestion for this project.

Why can’t Chord make something like that?
Great work.

I think they did make something “like that” and it’s called Poly. This s great if people want to DIY and need only BT and don’t want higher quality WiFi options or SD card. But Chord has chosen an all in one strategy with Poly as opposed to separate units for BT, WiFi, and SD.
