Is there a stereo input USB C ‘dongle’ yet, or anything really small?

Nice. I found this locally at an ok price. I was wondering if it’s class compliant

Might have similar issues on iOS as well.

On iOS, the built-in speaker still works when a 2-in-0-out audio device is connected.

That makes sense, good to know

This looks amazing. Saw it and immediately thought of this thread.

SYNTHERNET

AIF22 - USB-C Audio Interface | SYNTHERNET

USB-C接続のとにかく小さなステレオライン入出力オーディオインターフェイスです。This is a compact stereo line input/output audio interface with a USB-C connection.

Price: JPY 14000

Shame it costs $60 to ship from Japan (also, no idea how good it would be, but it does look great)

Thanks a lot for the Sonos recommendation! Works great, perfect tiny companion to record the Octatrack.
Unfortunately it seems to drain the battery on my Macbook if left plugged in, something to watch out for.

Picked up the new apple usb c to trs cable yesterday

Apple

USB-C to 3.5 mm Audio Cable (1.2 m)

Connect to 3.5 mm audio sources on your Mac, in cars, on airplanes, and more. It also enables ultra-low latency with AirPods Max.

and can unfortunately confirm that it does NOT show up as an input device at least on mac. It does have an ADC and DAC and says it’s ‘bidirectional’ however…

lerba · 2025-04-27T01:51:34.930Z

I’m also voting for the sonos adapter. Great value and I have zero complaints so far after almost a year.
edit: I’m a mac user (M1 15.4.1)

Katmat · 2025-04-27T05:27:55.852Z

I use these, dead cheap works a treat: Amazon.co.uk

I use one of these: AMS-22. Not tiny but pocket-sized with some really handy features.

Isn’t this for TRRS operation to support cellphone earbuds and gamer headsets with a built-in mic?

Zincqk · 2025-04-27T14:13:29.957Z

it’s trs for sure and now I’m seeing that sonos makes the same cable with the same ‘bidirectional’ specification. Kind of tempted to try that one but I expect it will also just show up as an output only.

Elijah · 2025-04-27T14:36:53.825Z

Those usb-3.5mm cables might only enable input functionality when connected to certain headphones like AirPods Max or Sonos Ace.

jemmons · 2025-04-27T14:44:39.635Z

If you’re talking the “Sonos Line-In Adapter” posted above, it is neither bidirectional nor does it show up as output only. It’s a line-in device. It shows up as input only.

jemmons · 2025-04-27T14:50:18.571Z

There is no specific headphone requirement. It just has to have a standard TRRS jack with the second ring wired to a mono mic. Unless you have a “call center” headset with independent plugs for mic and audio, this is how basically all wired headphones with integrated mics work. It’s very common.

Elijah · 2025-04-27T14:56:31.408Z

Here are the USB-3.5mm cables we are talking about:

Sonos

Sonos Ace Headphones Aux Cable (USB-C to 3.5mm)

An additional or replacement USB-C to 3.5 mm auxiliary cable for your Sonos Ace headphones.

Price: 19

Apple

USB-C to 3.5 mm Audio Cable (1.2 m)

Connect to 3.5 mm audio sources on your Mac, in cars, on airplanes, and more. It also enables ultra-low latency with AirPods Max.

These have 3.5mm TRS plugs. (It’s not the Sonos Line-In Adapter.)

lerba · 2025-04-27T14:58:19.205Z

This is the sonos cable you use for line-in:

Sonos

Aux Line-In Adapter: 3.5mm to USB-C | Sonos

Connect an aux audio source to Era 100, Era 300, or Move 2 using this 3.5mm to USB-C line-in adapter.

Price: 19

@Elijah I’m getting the sense you might be in the wrong thread, as this one is about stereo input usb-c dongles, not headphone adapters…

jemmons · 2025-04-27T15:29:46.112Z

Ah, I see. Sorry, the link above jumped me to the bottom of the page which featured the standard Apple 3.5 female to USB-C adapter and I made all the wrong assumptions

[edit: cut out a bunch of speculation here that would only confuse things further]

Zincqk · 2025-04-27T17:08:23.519Z

Have you noticed any latency with the sonos adapter? I’m seeing some mentions on other forums of a 75ms delay but maybe that’s just with sonos software adding in a delay to compensate for syncing at some point?

lerba · 2025-04-27T17:39:44.656Z

Absolutely, there’s noticeable latency. I would never use it for tracking, but rather for quick recording of ideas and sketches.
If you want low latency, you need an audio interface.

Zincqk · 2025-04-29T12:43:08.866Z

It’s donglier than I’d like since theres a split for headphones on the cable, but I think this is it:
