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

Nope, because the one with the ''louder'', less controlled highs is the left one, while at the same time the bass is less than the right one.

I asked Rob, and he said that the one on the right has a higher damping factor than the one on the left. And I guess that's why it sounds more controlled with 300 ohm headphones.

With the Sennheiser HD 579, the left one actually sounded a bit more detailed and cleaner.

I followed this thread since day one and its been stated that both outputs are identical many times but now 3 years later they officially sound different?

Yeah, they don't sound different. In fact, each headphone jack is connected to the same amplifier internally. The only way they could potentially sound different is if one of the jacks is defective or got dirt inside, something like that.

There could also be differences in the resistance/inductance/capacitance of circuit board etches, between the chip/device that drives the output, and the two jacks.

I suppose so however one would think Chord manufacturers to tight enough tolerances and QA's such that there would not actually be measurable difference between the two jacks.

I have personally never heard a difference and have just plugged in which ever jack came to mind.

Ahh that’s interesting, so my Sennheiser HD650 should sound better through the right hand port?

I just received the Mojo case. It's an original Chord one.

However really surprised to see it has a magnet to close the case. Why would you want a magnet next to audio electronics? I might be wrong but wouldn't it interfere. ... Also if the Mojo was dropped while in the case. I fear the magnet would pop open and the Mojo fall out. (Not that I intend dropping the Mojo, but accidents happen.)

EDIT: With Mojo case being made of aluminium, it probably blocks magnetism. At least that is what I came up with, after a google.

exactly the same caracteristics of sound that I found on mine since the first moment I opened and use my mojo. We have a better perception of sound I guess! SOME VERY FEW OF US HAVE GOLDEN EARS !! AND IM A TROLL!!

 

[Elecroestatico]

I need to replace the battery, What kind of screwdriver do I need to use?

Screw you!

Yes, with my HD 650 that definitely was the case. Tell me what you think when you've plugged them in both for a while.

 

[cirodts]

it sounds better the left door would seem

They do sound different, but a few people said its connected to the same amp vs somebody said that rob watts stated that they do have different dampening factors, so who to believe? perhaps the rest of your equipment is not revealing enough to show those differences or some people just have better hearing, or maybe you are crazy or maybe I'm crazy or maybe some mojos are made with more love: ....or maybe you have a fake mojo and only real mojo sound different, I'm gonna have to go for that last one theory!

 

[cirodts]

I with a degree I felt differences

This is literally what he told me in pm.

''No it's normal. But I am surprised you can hear it - nobody has spotted it before - the reason is that the one on the other side of the power switch has a little longer PCB trace, so the damping factor is not quite as good as the one close to the power switch. A bigger damping factor gives a tighter (in the bass) and brighter SQ. I used the power switch one before Hugo 2 and preferred that one!''

That explains why 300 ohm headphones sound better on the right, and other lower impedance headphones sound better on the left.

And if you turn down the leds and flip the Mojo over you get lower noise floor.
