within 24 hours, I think I blew out my empire ear lx iems from the mojo. Had connected to my iPhone w camera adapter and it went to maximum volume automatically on start. Is that something that happens? Thank you.

No it doesn’t just jump to max volume after being turned on.

The mojo2 went to max volume or your iPhone?

Although I've only had the mojo2 a couple of weeks, and not used everyday, i have not noticed volume jumping on start

Mojo2 always start on the same volume that you had at powered off.

Small indie company. Some units hiss. Some units take 30 min to warm up. Others are perfect. I've been told above (by an engineer!) it's too small a company to be expected to get it right almost always, so we need to live with this crappy QC.

Has this ever been clarified, I say this because in the Aful Performer Impressions Thread using the Aful P8 IEMs which are very sensitive (comfortable listening levels just before the higher gain light is on), and some people are saying absolutely no noise floor hiss at all, were as I and another person on there say they can clearly hear a faint hiss, also this review is one of the only Chord Mojo 2 reviews where this has been mentioned at the end of the review under Cons " There’s some hiss with ultra-sensitive IEMs", where as many other reviews say that even with ultra sensitive IEMs the Mojo 2 is dead silent, is this unit variation or hearing discrepancies?

I only get a hiss with two of my IEMS, the Aful P8 (apparent), and the Blon5S (very slight), testing methodology: Plugging IEM into Mojo with volume set to minimum, and no USB/Optical/Coaxial cable connect.

I use Mojo 2 with Andromeda 2020 and I confirm that the hiss I hear when the music isn't playing is there, but it doesn't bother me

If you have no USB input connected at I wonder if the analogue input is enabled and being because the input is open circuit it’s generating some noise. Do you get hiss if the usb is connected but no music playing?

Yes, I just did it without input to confirm.

It doesn't really bother me too much, it's just odd that some people claim it isn't there.

I get some hiss with some of my IEMs(*). Most of the time it is only noticeable when I'm looking for it and have the room quiet. And even then I'll have to plug and uplug the headphone jack over and over while the IEMs are in my ears to be sure. I'm using an ifi IEMatch+ though and that's solving it completely for me. I know it's mainly just a "peace of mind" thing, since I have to actively listen for hiss in some cases.

*Sound Rhyme SR8 and DTE900, Night Oblivion Butastur, Aur Audio Aurora, 64 Audio Nio, Andromeda 2020(not a surprise)...without going through all my IEMs and double checking. There are of course others with no such issue(Z1R, M9, Monarch 2, etc)

Depends on app you are using. Roon ARC had this problem with some usb dacs.

There is a tiny bit of hiss with my Shure SE-846, but nothing to worry about IMO. Basically I can barely hear it while the IEMs are connected. Much less than most amps though and about the same as low power mode from the 1/4" jack on my RME ADI-2 DAC. It should be noted that the IEM output of my RME is dead quiet.

I also tried using iEMatch+ and it completely solved the hiss problem but Andromeda 2020 sounds horrible with it

which gain did you use on iEMatch+? The highest one is 1Ohm output impedance, with that OI, I do not think that it makes your Andro sound horrible

Not needed same as iPad usb c output

I'm keen to see how this goes for portable use but I've had lots of wobbly USB C leads but no Lighting disconnects so far.

USB C is a more convenient standard but is the connection as robust, only time will tell.

Hello my dear friends, im here just to say that my mojo2 is my most used hardware for sound this year. Its always with me with some very different headphones, work, home, bed etc.

I'm thinking upgrade my living room with new TV and speakers connected via second mojo2. Have anyone tried this via SPDIF?

I haven't but I'm sure people have. Make sure you configure your TV to output two channel PCM and not multichannel Dolby sound as the Mojo won't decode Dolby etc.
