  • USB-C to Jack DAC compatibility list

Devices tested: Pixel 6a

DAC Model: Fiio BTR3K

Result: Both Bluetooth and USB working fine

The only annoying thing with LDAC bt codec is you have to manually switch it to HiRes mode in developer settings and it goes back to Best Effort mode each time device connects but that is the same for stock android I think

Devices tested: Pixel 4a, Pixel 6a
DAC Model: Gentronix something, can't find it, Amazon
Result: Not working, but it did

This is really strange. It worked normally on my 4a, and then I plugged it in again and it stopped.
May this be something with data transfer allowed? It does not show up as headphone but as usb device, I cannot control the connection from the device.

The dongle works totally fine from my laptop (Fedora Linux, modern Kernel etc.)

update: confirmed working after some time.

Result: working very well but after quite some delay and with weird not being recognized. Works on all devices

I am using "Vanilla Music" which has a "only play over external speakers" mode, so preventing cringe playing from internal ones. But it took many seconds to even recognize the headphones?

Update 2: the converter only works on my digital headphones. A pair that required analog input did not work. (While the apple one did)

Also note: the DAC disconnects randomly. Setting "Allow new USB devices" fixes this. (Why does GrapheneOS not remember the device?)

But the sound quality is perfect for me.

Devices tested: Pixel 6a
DAC Model: Hama 00200318 "USB-C Audio Adapter"
Result: complete garbage. The sound is completely distorted, especially the Bass. The build quality is also cheap, thick cable without fiber or anything, bad on the port.

The Seller (quote: "wholy fuck!") took it back immediately ;D

Also tried the UGREEN 20194 with a Fidelio headset with some well-known tunes just now. Definitely a step up from my JBL Reflect Mini in-ear ones. Much livelier and rich sound. Paid 146 SEK (maybe something like €13). Plug & play on a regular Pixel 6 also.

Device tested: Pixel 8 Pro
DAC Model: Anker USB C to 3.5mm Audio Adapter
Store link: https://www.amazon.com/Anker-Adapter-Female-Samsung-Devices/dp/B08Z3B5QL3

Works out-of-the-box and comes with CTIA pin mapping compatible with all common 4-pin plugs not targeting the Chinese market.
Can't complain about audio quality, volume is a bit quiet though compared to Bluetooth headsets or the phone's built-in microphone/speaker.

Moondrop FreeDSP cable works perfectly (Pixel 6a).

Not a USB-C to jack per se, but I thought might interest some to know that it's working fine with GOS.

If you don't use the EQ functions, no need for the dedicated app (which apparently works poorly + is a privacy nightmare anyway).

Device: Pixel 6
DAC: iFi GO Link

Plug and play. The sound is awesome. I thought the UGREEN 20194 was good, but this is far better.

I've got an issue with iFi Go Link on Graphene OS: if I start a music app before plugging the DAC in and then plug the DAC, then I'm hearing loud intermittent noises coming from the headphones. If I stop the app, plug the DAC in and start playback, audio appears as normal. Is that expected behavior?

    865be553dc4f5b2b It does so with any music app? I use HiBy, Plexamp, Tidal and Spotify mainly. Suppose I've tried VLC and Auxio with the Go Link even, on a Pixel 6 with GOS, and I've not had that.

        ujjayi Yes, it does that with every app and now my method doesn't seem to work anymore - all I get on Graphene OS is noise, even after a reboot and plugging in and out. And again it does work flawlessly on Xperia and PC.

          This appears to be a bug, but I cannot confirm whether it's Graphene OS or Android 14 specific. It is triggered by starting an audio playback and plugging the DAC in. It does mute the playback on the speaker but DAC output will start to output loud noises. If you pause the playback, plug the DAC in and start playback, it may play normally. I initially observed this behavior on WhatsApp and there no amount of plugging in and out could fix the problem. I suspect it's because WhatsApp while running may activate audio output chain even though there are no calls or notifications coming at the moment.

          Can anyone confirm the behavior on Graphene OS and stock Android 14?

          Devices Tested: Pixel 8
          DAC Model: Beyerdynamic PRO X USB-C Cable (USB-C to 3-pole Mini XLR)
          https://north-america.beyerdynamic.com/pro-x-usb-c-cable.html

          Plug and play. No problems with playback; excellent audio quality and gets loud enough to use my headphones as speakers. No problems while using the cable's built in microphone. There is a small delay (~1 second) when using the cable's volume and play/pause buttons.

          Tested with Beyerdynamic DT 770 PRO X headphones (48 ohms)

          Device tested : Google Pixel 6a
          OS : GrapheneOS
          DAC : Beyerdynamic PRO X USB-C CABLE 1.6 M («Connection cable for PRO X and PRO headphones (1.6 m) with integrated DAC») / DAC ref. : ESS ES9280A PRO
          https://europe.beyerdynamic.com/pro-x-usb-c-cable.html

          Tested with Beyerdynamic DT 770 PRO X LIMITED EDITION headset ( https://europe.beyerdynamic.com/dt-770-pro-x-limited-edition.html ). Works well. Powerful sound. Cable-integrated controls (volume up and down + pause) functional. The headset's built-in microphone also works, but I haven't yet tested its quality (I'd like to make sure there are no micro-cuts).

            I use Pixel 6a with onkyo hf player, dragonfly red and sennheiser HD25.
