Apple dongle will be volume limited on Android. Unless you want to jump through hoops every time look for any CX31993 dongle. Ignore ALC5686, KT0210 or mystery dongles, they have worse metrics than all above. Next step up is CS43131 devices staring from $25, only needed for full size headphones and shorten battery life with four times higher power draw.
In my experience playing around with car radios, a good tape adapter on a oem radio sounds better then aux on oem radios (even on aftermarket radios) . Of course, once you feed an aftermarket radio files, it destroys that tape setup. Car Aux ADC's would rank lower then the cheapest Realteks.I use a usb-c dongle to aux to tape deck adapter in my 1999 Lexus. Noise noise every where, but I can still enjoy the musicDam Lexus and it's electronics will last forever.
I'm going to get the apple dongle for my Samsung phone.
AFAIK these are simple analog inputs directly feeding the amp stage, I don’t think ADCs are used.
Ever thought of fitting a smart radio/media player such as one of the Pioneer ones?I use a usb-c dongle to aux to tape deck adapter in my 1999 Lexus. Noise noise every where, but I can still enjoy the music

I wouldn't bother with ALC5686, their data sheets look worse than CX31993.Other CX31993 tested in this website, like Meizu mblu lifeme pro (also has MAX97220 as independent amp) and Yongsee y01, lacked 50mv testing, but I have a Jcally JM6 pro with CX31993 + MAX97220 and the hissing with IEM is terrible, much worse than with the integrated laptop headphone output. It's only useful with lower sensitivity headphones such as a DT770 pro, anything over like 100db/mw and it's really bad, I've seen some comments on Reddit saying the same, so yeah I believe it's not a defective result shown here, also remember seeing a similar jitter pattern in the 12k test with the Meizu lifeme pro review, so yeah it's a CX31993 thing.
I would like to see a Realtek ALC5686 based dongle tested with 50mv measurement, it is the other super cheap dac on Aliexpress, maybe it does better in terms of noise floor? but yeah for now at very low prices it's just not worth it to buy anything other than an Apple dongle or a cheaper CS43131 based dongle like Jcally JM20.
Yes, the Lexus integrates the Nav, climate controls, pc and audio all in one unit, so replacing the radio I loose other things like AC. Unless maybe I find a lesser spec Lexus with separate AV controls, which I'm willing to do if I find it cheap enough, for now, tape is ok.
Yongsee Y01 appears to be built around the CX31988, the “balanced” version of CX31993 (plus other differences?)
I would argue that this is exactly the way it should be.
Only if Amir assumes the user wants to pay 2-3 times more, incurring current draw increase by four times(CS43131). But that would be a waste driving IEMs on portable devices.
We are not after high-resolution but rather, enough power to drive your headphone and absence of noise when driving sensitive IEMs and headphones. Both of these limitations are quite audible and don't relate to the thing having enough resolution or not.
