Best USB-C to Audio Jack Adapter for FP4

Hi there, so there is a lot of controversy about Fairphone dropping the 3.5mm audio jack, like here: As it often gets mentioned, we can just use a USB-C to audio jack adapter. I will need one, because I still use the 3.5mm jack. Among other reasons, a lot of small bluetooth headphones don’t have the battery capacity I require. I would like to collect some ideas for good adapters. I did not order the “official” adapter along with my FP4, because it beeing out of stock made me unsure: USB-C to…

Which adapters work and which don’t? What exactly works (incl. Volume control etc)? Does it include a DAC chip? (Digital to Analogue Converter)

Fully functional adapters

• Sharkoon Mobile DAC PD
  todo: edit which exact features work

• cellularline music enabler type c. Tested with sennheiser CX 2.00G, audio output and all three buttons work.

• AXFEE USB C TO 3.5 mm Adapter, 90° w/DAC Chip. I have the 90° grey variant, sometimes it requires a second plugging in (but not sure if that’s an adapter issue, or just lint…). Works fine. More variants than on Amazon US exist.

• hama Audio-Adapter, ArtikelNr.: 00122338 (gold plated contacts; tested only playback)
  Works with a mini mic, a device for streaming audio to hearing aids, cochlear implants, etc. OEMed by many manufacturers; output to devices via FM; input via audio jack (among other possibilities).,

• hama Audio-Adapter, ArtikelNr.: 00200318
  (sound with InLine Woodon-Ear headphones great, nothing else tested)

• hama audio and charging adapter, ArtikelNr.: 00187206 (includes DAC, audio playback works, simultaneous charging does work using the FP USB-C 3.2 cable with apple USB charger)

• hama audio and charging adapter, ArtikelNr.: 00200319 (same as the one above, just without gold contacts)

• Google GA00477-WW USB-C Digital to 3.5 mm (Play/Pause, Volume, Microphone - work fine)

• Samsung EE-UC10JUWEGWW - audio playback works fine

• Sandstrøm USB C to 3.5 mm audio adaptor - S6UC3519
  Audio tested ok

• Vention USB-C Male to 3.5MM Earphone Jack With DAC Adapter 0.1M Gray Aluminum Alloy Type Works okay with simple earbuds, volume is good. Haven’t tested volume control/mike. ~ 200 CZK/ 8 EUR.

• Fiio BTR3K Tested in USB DAC mode, which needs an USB-C to USB-C cable (not included) to function. Media controls weren’t tested. Bluetooth also works.

• FiiO KA3 Is a bit power hungry. Comes with a USB-C to C cable. Media controls weren’t tested.

• Sharkoon Mobile DAC - tested with a Marshall Mode and a Sennheiser HD 380 Pro. Audio playback works fine with both. There is soft but noticeable noise with the lower impedance Marshall Mode (30 Ohms), which is not an issue with the Sennheiser (54 Ohms). Play/pause and voice recording work fine with the Mode (Sennheiser doesn’t have an inline remote). Skipping ahead/to the next song (by double clicking) works as well, although some app behaviour is weird (e.g. double clicking in Podcast Addict sometimes pauses, sometimes skips ahead, and sometimes does both). This is a DAC suitable for high-impedance headsets, not low-impedance ones.

• Anker USB-C to 3.5 mm Audio Adapter - tested with Marshall Mode and Sennheiser HD380 Pro. Everything works as intended: no noticeable noise, playback button functions flawlessly. Sturdily built: all-metal housing and thick, braided cord. Only available on the US & German Amazon store.

• ddHifi TC35B 2020, https://fiio-shop.de/988/ddhifi-tc35b-2020 - tested with beyerdynamics Soul Byrd and active speakers from Nubert.
  Audio Playback works fine, no noise, no crackling, wonderful sound. The buttons for volume, play, pause are working. Used as headset the microphone is working as well as the buttons for volume and for hang up. And you won’t find a smaller one, just one piece of metal, with a plug on one side and a jack on the other, no cable between them. Recommended.

• sunnylan, simple but efficient adapter with a 2 in 1 function : you can charge and use a 3.5 headphone. It has a DAC inside, and it’s only 17€ : USB C to 3.5 mm adapter for headphones and charging, C-type 2-in-1 audio adapter with fast 60 W charging (<–amazon .fr link) I use it every night.

• Phoie USB C to 3.5mm Audio Adapter and Charger, 2 in 1 USB C Dongle Headphone Jack 60W.
  Works without issue for simultaneous use of both headphones and charging (supports rapid charging). Has a solid quality look and feel. Purchased from eBay here: https://www.ebay.co.uk/itm/255838243384

• FIXED LINK USB-C/3,5mm jack with DAC chipem (FIXL-CJD-WH) white

• Belkin RockStar 3.5mm Audio + USB-C Charge Adapter (18 W) with built-in DAC pleasingly tested without any problems with stereo headphones Sennheiser HD 25-1 as well as with mono headset Jabra Evolve 40 Mono; I use it daily.

• iNassen Adapter USB C Auf 3,5 Klinke Audio and play/pause working, volume I can’t verify

• Bphuny USB-C auf 3,5mm Aux Audio Adapter Hi-Res DAC High-Fidelity DAC Chips with up to 96 kHz/24 Bit, ADC with 384kHz/32 Bit, 60W PD, tested on FP4.TP1X.C.079 / 8 Nov 2023.

• Buxton BAA-100 BT Not exactly USB-C jack - it is Bluetooth to jack. But it works great and still allows you to use wired headphones with FP4. It is super small and battery lasts ~8 hours. Integrated microphone and volume control. Tested by peci1 on FP4.TP1X.C.079 / 8 Nov 2023 (also worked on A11 and A12).

• iRig HD 2 USB-C audio interface. 96kHz Digital Audio with 24-bit A/D conversion. High-quality instrument-level 1/4" Hi-Z input jack. 1/4" Amp output jack with switchable output “FX” and “Thru”. 1/8" Headphone output with preamp and level control.

Problematic adapter

Describe problem:

• Apple “USB-C to headphone Jack”
  Audio tested with a video and mic tested with the voice recording. The buttons on the remote (of a Sennheiser CX 2.00G) seem to work partially though: the single press centre button works, but volume buttons only raise the volume all the way up or all the way down and double pressing the center button to skip a track is not recognised by e.g. Spotify. Please note that this adapter hasn’t worked for every user, as some report hearing a loud hissing/static noise during playback.

• Baseus Audio converter USB-C to 3.5 mm jack charging and audio - audio does not work, have not tested charging

• TINICR, https://www.amazon.de/gp/product/B07WZN9QXM: charging worked, phones did not.

• Teufel, https://teufel.de/usb-c-auf-kopfhoereranschluss-adapter-106314000:
  does not work with every headset:
  → works perfectly with separate headphone and no-name-microphone without buttons
  → with Beyerdynamic Soul Byrd playing music is fine, wonderful sound, incl volume setting and pause/resume-button - in telephone modus the buttons for volume and hang up are working, I hear my partner, but the microphone is dead.
  (contacted Teufel: they confirm problems with the Soul Byrd and offered me a return.)
  So, for just music or a headset without buttons this adapter is a recommendation, for others not.

• NIMASO Adaptateur USB C Jack 3,5mm : sturdy looking cable, but noisy hissing sound at low sound level, does not work on my windows 10 PC, no jack detection. I replaced it with an apple adapter, without issues so far.

Adapters not working at all

• Huawei CM20 USB-C/3.5mm-jack adapter: not working at all, one forum member mentioned that there’s no driver chip in the adapter, so this adapter only works with certain huawei phones.

• “Type C To 3.5mm Jack Converter Earphone Audio Adapter Cable Type USB C To 3.5 Mm Headphone Aux Cable Type C Converter Adapter” sold by Pro Tech Gear Store via AliExpress; doesn’t work at all with Fairphone 4; it seems it doesn’t contain a DAC.
