Hello everyone. New around here. Made this account specifically to troubleshoot this issue.
I’ve attempted to make my fairbuds xl work with multiple different usb-c to 3.5mm jack adapters now and even confirmed that a signal is indeed passed through the adapter to the headset by using two other usb-c headsets.
What am I doing wrong? Do I have a wrong adapter?
I would connect the headphones straight to my pc but unfortunately, that produces this rather unpleasant hissing noise. If anyone knows how to resolve that, that would be a good solution also.
Thank you in advance.
Welcome to the Fairphone community.
I don’t understand exactly, what you are trying to do. How can a USB-C headphone work with a jack adapter?
Which ones exactly did you try where?
So what are you trying to connect them to?
I tested the adapter with two different Sony WI1000X earbuds.
Anything that outputs audio, phone, pc, etc.
That’s interesting. Are you saying that the headphones are only able to connect with a direct usb-c connection?
Essentially I’m trying to get a wired connection to the headphone without the awful hissing noise.
I can assure you they work both wired and wirelessly.
With USB-C as you said? How can they connect to a USB-C to jack adapter?
USB C female to 3.5 male
not the more common
USB C male to 3.5 female
Technically they have a micro usb which I convert to usb-c, which I then convert to a jack.
So:
sound
PC → jack → usb-c → micro usb → WI1000X
Take out the usb-c to micro usb adapter and plug in the fairbuds xl like so:
no sound
PC → jack → usb-c → Fairbuds XL
It’s a usb-c male to 3.5 female are you saying that wouldn’t work?
It’s the same fairphone sells here:
And recommends in the faq:
This ‘adapter’ is a USB-DAC that converts the digital singal of an USB-C output to the analog input of an audio device. It can’t convert the signal in the opposite direction.
No! That works from the FP4 USC C female and provides a Female 3.5 for headphones with a 3.5 jack. The adapter has the DAC to convert digital to analogue.
In a computer with analogue out you just need a straight through analogue.
I’m unsure if my adapter is a dac or analog. Anyway to tell beyond the tests I’ve already conducted?
I still don’t know, what you want to do or what you want to avoid.
Which connection exactly gives you the ‘hissing noise’?
Then I think we can safely rule out that my adapter is a usb-dac.
Why? It won’t work anyway.
What makes you so sure of this?
Like I said, It’s working for my earbuds, why shouldn’t it work with the fairbuds xl?
Because you want to convert an analog signal to a digital, a DAC does the complete other way, it converts digital to analog.
