Thank you for all the answers. Always amazed to see how Head-Fi users are nice and efficient.
Sometimes we are hard to drive.

Yes, I've had this same exact problem. If you move the Mojo up and down, the bass and lower mids will gain authority again, but for me this was so annoying that I needed another way to fix it.
So I bought a Hifime USB High Speed Isolator, and now the bass is fine. You can also add 2 Jitterbugs, connect your Mojo to the isolator, then the isolator to the Jitterbug, then the Jitterbug to your USB port, and the other Jitterbug on the other USB port closest to it.
This way, you'll get a good amount more bass and vocal authority as compared to using the Mojo directly to USB. Treble also becomes more controlled, and the sound just gets cleaner
Despite the cubersome effort, it sounds better than any DAP or phone under 500 bucks. Skip if u want to stick with an inferior sound. But damn thing makes problems like this sometimes. The problem he mentioned is an isolated issue. Mine too have a similar issue now, but it was never there for the 1 year I used it before. Something is broken. The solution he mentioned here is not a solution for everyone, I strongly belive something is broken with his mojo too as I never had a problem with it for long. But that being said, unless ur headphones are not too revealing, u may not "hear " the improvement. But I think its hard to ignore the tightness of this thing. I am coming from a AK70. This was a clear improvement to me.Thanks for this. I was looking to return to a Phone+Dac/Amp setup and was contemplating to give Mojo a try.
I guess I can skip this one.

I tried a demo set at a store just now and listened for over an hour. Tested songs of various quality from apple lossless to mp3s.
The unit performed very well - I can even connect using a Lightning-to-micro USB cable without the Apple CCK.
Coming from an iBasso DX220 with host of problems e.g high heat, OS bugs, laggy GUI performance, battery drain, playlist compatibility issues - I'm seriously considering going back to phone setup, plus I won't need to manage an SD card as well.
If you are not confident about the mojo, use it while it's warranty last and sell it off. Ideal backpack setup can be cayin n3-coaxial- mojo with hiby link. Use phone to change songs and so on while this bundle stays in a backpack. Or like me shanling g m0 - usb - mojo for lossy stuff. I am yet to get my clip for m0. My plan is to keep the mojo in my pocket while walking around and clip the m0 to the pocket itself. So to change the song I just have to click on the button. Wish m0 had 3 buttons.
How long have you had this unit?It happened to me now as well. My Chord Mojo has been working intermittently and it has grown worse and worse. I read about the battery issues they seem to have and I decided to open it up. It literally flew apart as there was tremendous pressure caused by the battery as it appears I too am affected. There is no way I could close it again seen as there is a 8mm gap between the case-halves when the battery is left in between.
I contacted Chord since some people earlier in this thread got replacements sent out to them. All I need is a new battery (I hope, although maybe the circuit board has taken some damage from being under such pressure from the battery.) I was quoted a sum about the cost of buying a used Chord Mojo.
If I were to pay Chord for a new battery, it might not be enough to fix it since the circuit board might be bent from the battery. Additionally, if replacing the battery would fix it, what keeps this from happening again with the new battery?
I think I am better off buying a new used one, although I will probably not buy another Chord. I wish I would have read this thread before I got mine. I am really disappointed in Chords QA and customer support and will definitely end up going with Fiio in the future. Having scanned threads on them, they appear to be far less failure-prone.

How long have you had this unit?
All products with lithium based batteries - be it a laptop, mobile phone, etc will eventually run into battery degradation / bloating after it's rated charged & discharged cycles, it's inevitable.Soon to be 2 years, but I got it from a store that sold it as "previously used", which I think means there is no warranty. I don't think this is a fault that I as an enduser caused, but rather a fault which existed already from the factory. The consequences just appear as time passes, and potentially quite dangerous ones at that, but I would have expected what I thought was a high end brand to have better quality control and offer more than to try earn more money from the issue.
I have pretty much given up on my Mojo at this point. I just wanted to add my name to the list and make other potential buyers more aware.
Edit: Battery says "Mfg date:0915," so I assume the battery was manufactured in september of 2015
Yeah I get that, although in my case it was less than 2 years. Does anyone know if batteries sent out by Chord today even have a different manufacturing date? I just didn't expect a battery to cost more than a new unit. I would also expect batterylife to decrease over its lifetime, but not that it would damage other parts or become a hazard.All products with lithium based batteries - be it a laptop, mobile phone, etc will eventually run into battery degradation / bloating after it's rated charged & discharged cycles, it's inevitable.
For 3-4 years, I'd say you got more than fair use of this unit.
Ok, it is obvious that you are frustrated and angry about this, but bear with me while i try to provide a more balanced view on things.Yeah I get that, although in my case it was less than 2 years.

Does anyone know if one can buy a 7,4V 12,21Wh Li-Po battery from somewhere for less than like 100USD?
Has anyone tried replacing Li-Po with similarly rated Li-ion? I guess the charger will be severely missadapted for a Li-ion which should have different trickle charging, cycling etc, but I wonder if it still wouldn't be safer than the stock solution.
I opened mine up a few weeks ago, and there was no visible battery swelling.Could someone please open their Chord Mojo and measure the battery pre-swelling if you have one? I would be very grateful to anyone who would be willing to do this for me. I just measured the battery in mine with a caliper before it struck me how pointless it was, especially the thickness.
