Hi,
Thanks for the useful discussion these days, especially for comments from CaptainFantastic and Tiax. I think I now reach a conclusion.
I now have two Mojo2 at hand and they are both new. The hissing I have noticed does present at both unit similarly. It is a universal hissing picked up from my shure 535 IEM since after mojo2 boots, it is not loud but noticeable, seems like not influence my music, but definitely there. Such hissing does not relate to volume, connection of USB, etc. The hissing can be easily fixed by attenuation (ex ifi iEMatch).
My conclusion is the hissing is normal for mojo2 and my IEM combination. Otherwise it is hard to believe both new mojo2 has similar defective hissing plus their SN is far away from each other. I will keep the one and return another (simply choose the one with less hissing), with Amazon in US, it is super easy to return.
It seems like Tiax and CaptainFantasitc may have different issue, since their hissing is more like a defective unit and easily proved.

I have Shure 846 and I have no hissing with them. Could it be a problem with your 535s?

I heard a rumor (only a rumor!) that the iPhone 15 will be only wireless charging; no connector at all. That's pretty radical move because it would cut off all connection options, not just charging.

Wireless charging only doesn’t mean it can’t have a lightning connection as well. As long as it doesn’t charge from it it bypasses the EU directive.

The Chord Mojo 2 is 2022’s best DAC (and here’s why)​

It's been a while since I've used the Mojo 2 but I recently purchased the Poly and got it up and running and I'm loving the pair!

Doesn't look like anyone responded to you, so I reached out to Chord support for this particular use-case. I was curious since I recently acquired a Mojo 2 and Poly.

thanks, this is perfect!

so i just got the chord mojo 2 and have it hooked up to the IPAD Pro running IOS 16.1.1. When I play any song in the Apple Music, the resolution does not change on the Mojo 2. It only shows 44khz for all Hi Rez songs in the Apple Music. I have the Apple Music set to Hi Rez in settings for Apple Music. Any thoughts what might be going on here? I am using the standard USB C cable I got with the IPAD Pro. I thought the resolution change was seamless on the IPAD/IOS. It does the same on the IPHONE also.

Are you 100% certain the setting is Hi Res and not just lossless ?

I don't have a Mojo 2 but I connected my iPad mini with the same 16.1.1 with the same Apple charging cable and it streams hi res from Apple Music to an ifi Gryphon with no problem. With a different but basic cable it also streams hi res to my original Mojo. Logically it should work the same to Mojo 2.

Something seems off and the logical first guess is the audio quality setting.

You are not perhaps inadvertently using data rather than wifi and the data setting is to something other than hi res ?

 

[AussieMick]

+1 for the audio quality setting.

Mojo2 - Poly - Audeze LCDI4

It’s just wonderful. Really wonderful.

 

[turbo87]

no, i double checked the setting in AM. It is set to Hi Res in the AM settings on the IPAD. Will probably mess with it tonight. thanks

Is it safe to use a Balanced Cable with a 4.4mm to 3.5mm Adapter with the Mojo 2?

I remember reading that it wasn't safe to use such a connection with one of my DAC/Amps, I can't remember if it was EarMen Sparrow, Mojo or one of iFi's devices.

 

[Guy Fawkes]

Is it possible to stream music from the device (Android) to the Poly using the UPnp Renderer function of UAPP?

Can anyone give me an answer to this question?

I don't think so, I also have the ifi iDSD black label no hissing with the 535. chord told me it is possible for sensitive IEM to have hissing. Also based on my search it is common for low impedance IEM to have hissing, the hissing or not really depends on the combination of DAC and IEM. Maybe 535 do , 846 don't have hiss with mojo2. I know it is strange, but there really nothing I can dig in now without buying new IEMs and DACs.

Can anyone recommend a reliable lightening to micro usb cable for the iPhone to connect to the mojo2. Will a lightning to USB C work with the mojo2. Thanks

I use the Fiio LT-LT1 Lightning to USB c (as recommended here on this forum) and it works well.

Dunno about using a 4.4mm to 3.5mm cable on a single 3.5mm port of the Mojo 2, but PW Audio released an adapter that leverages both 3.5mm ports for a single 4.4mm port. I ordered the 1960s version of this. Should be arriving next week!
