I bought this adapter to be able to use my senheiser headset, but the smartphone does not allow me, says that this adapter cannot be used "The USB device is not compatible".
It is from a consolidated brand, Gorilashield.
Can someone help me? Is there any way to unlock to be used?

Does the adapter contain active DAC converter?

I bought NILLKIN HIFI DAC Earphone Amplifier Type-C to 3.5mm from China and it is working fine on my Samsung S20 Exynos.
Nillkin Type-C to 3.5mm HiFi DAC Amplifier Pro Review
Is it worth spending money on Type-C to 3.5mm adapters with DACs or go for a standard adapter? Which are the best Type-C to 3.5mm Adapters with DACs and without DACs?
www.pickybeast.com
You simply need USB-C to Jack cable but with DAC.
More explanation (copied from web):
Active vs. Passive USB-C
The biggest problem with USB-C audio is its lack of standardization, which is ironic considering USB-C’s purpose is to standardize USB connection types. The problem lies not with the USB-C specification, but with the companies that design smartphones, dongles, and headphones. Here’s why this can be such a confusing mess: (Note that the remainder of this article will only reference USB-C headphones. Keep in mind that the same principles apply to USB-C dongles as well.)
Some smartphones send audio data through an onboard DAC (usually embedded in the phone’s processor) before sending it out through the USB-C port. If this is the case, almost any pair of USB-C headphones will work. If the audio stream is converted to an analog signal before it goes through the USB-C port, then connected headphones do not need their own DAC. These are known as “passive” headphones.
However, some devices send audio data through the USB-C port as a digital signal. As such, connected headphones will need their own onboard DAC and amp to convert the audio stream from a digital format to an analog format. USB-C headphones with an onboard DAC/amp combination are known as “active” headphones.

The holder with 3-in-1 adapter is the choice for you who want to connect a headset to your device while charging it. You can also connect the device to your stereo AUX input in order to play MP3-files. 40 cm adapter cable. When you put the device in the holder, it is automatically connected to:
- Mini USB for charging
- 3,5 mm audion for sound out
- HTC Ext USB for original headset
The holder is designed with a tilt swivel, this means that you can adjust your device in order to avoid reflections in the display. The O2 XDA Orbit 2 holders have a perfect fit and holds the O2 XDA Orbit 2 firmly in place.
Attach the holder onto a ProClip Mounting Platform in your vehicle and you will have your O2 XDA Orbit 2 in easy reach -safe and convenient.

Going to get me one of these I think
Looks good!
(Really expensive though!)
Looks good.
but tell me, what happens when you slot your TC into the cradle? My experience is that this type of set-up defaults the audio out to the USB/3.5mm socket and therefore doesn't let you play your sat-nav instructions through the TC speaker.
Fine if you want to play through the car's audio system, but not so good if you want to listen to the car radio and use your sat-nav at the same time.
Is there some way to force the audio through the speaker with this type of cradle?

Yes that is correct, I'm not sure of any reg haks to push the sound through the TC speaker when docked.... although i guess there will be as when docked the TC will play your ring tone through the speaker.

It would be good to hear from someone who already has this. I think I'll get one but didn't get clear answers to all my questions when I asked the supplier. It sounds like:
When it's plugged in, if you do not use the headset or a BT headset, and answer the call using the handset whilst plugged in, you will get the sound through the speaker but there will be no mic so you won't be heard.
As for TomTom, if you want to listen to the radio, surely you'll be able to select the sound off menu item in TomTom.
Also, if you unplug your 3.5mm from the device, you could plug it into the headphone jack of an ipod and listen to an ipod through the stereo.
I'm gonna buy the 40cm one and put the 3 in 1 in the glove box. I've also spent £8 today on a cigarrette power socket for the glove box.
Should be cool if it all works well

Question:
When it's plugged in, if you do not use the headset or a BT headset, and answer the call using the handset whilst plugged in, you will get the sound through the speaker but there will be no mic so you won't be heard.
Answer:
Yes that is correct, I dont have this mount but i use the same 3-way adapter, I use an old HTC headset which includes a MIC, i chopped off the leads to the earbuds and just route the mic in where the speedo is. The 3.5" outet does not support a MIC AFAIK so you have to use a mutliated HTC headset
Question:
As for TomTom, if you want to listen to the radio, surely you'll be able to select the sound off menu item in TomTom.
Answer:
When using tomom, sound will be routed to the 3.5" outlet and the HTC outlet. There may be a cab out there that can route sound to the Touch speaker even when connected to a HTC jack.
Question:
Also, if you unplug your 3.5mm from the device, you could plug it into the headphone jack of an ipod and listen to an ipod through the stereo.
Answer:
Mmmm think you have this the wrong way here, what your actually stating is you connecting your IPOD to your PDA.... In theory the 3.5" jack output is for attaching a tape adapter, FM transmiter or just earphones oh and maybe a 3.5" male to 3.5" male if your stereo takes a 3.5" aux input and also a 3.5" to left ad right RCA type...
Connecting your ipod to the 3.5" will not make it come through the stereo
Hope this helps

G1 Handsfree Audio Solution??

Hi, I've been using my G1 since its release. I recently sold my iPod touch and am trying to replace it with my G1. I got an HTC adapter that plugs into the HTC mini usb and pushes to a: (1) Charging mini usb, (2) Headset Mini usb, (3) 2.5mm w/inline mic, and (4) 3.5mm w/inline mic. In my car I have one of those 3.5mm to tape deck adapters. The problem to which I can't find a hardware solution and hope to find a software solution is; When I plug in my "3.5mm/tape-deck" adapter to the 3.5mm of the HTC adapter when I receive calls the inline mic input gets pushed through to the "3.5mm/tape-deck" which then gets "dead-ended" in the tape player. I was wondering if there is a way I can override the mic input to stay on the built-in mic on my G1. Sorry if this doesn't make sense I'm doing my best to explain my problem. In theory this should be an easy fix, I think. I'll accept a hardware solution I suppuse but I'd prefer a software solution.
PS: I'm running CyanogenMod 4.2.14.1 So my phone is rooted and you can post root only solutions.

it makes sense, its just that I have no knowledge of anything about cars at all! haha
I use this to my advantage and use it as an almost hands-free device.
I don't quite know what you mean by "dead-ends" in the tape player, it should just hold the music and have the call, then when it ends, the music starts back from the pause.
I think the amount of people that do that are greater than the people that want the music to play and talk on the phone at the same time.
You can always unplug the phone and pick it up if you want to talk like that, with that phone in your ear.
Thanks for all the responses. I think I need to clarify this. This is the adapter im using: (edit: I am not allowed to use outside links. well its the htc 4 in one adapter. Its like the first one that pops up when you google HTC 4 in one adapter)
My problem is that my 3.5mm/tape-deck adapter has only 2-rings but the mic is automatically routed through, as though I had a headset plugged into the 3.5mm port. So when someone calls I can only hear them and cannot speak into the mic even though there is a mic on the phone. The phone "thinks" that there is a mic that I can speak into. I need a way to force route the mic input to the embedded one, even while my tape-deck adapter is plugged in.
The ultimate goal of all this is so that I can do everything on my phone in my car without picking it up and thereby maximizing safety.
PS If you don't understand any of what I said just ask and I'll do my best to explain. I am using layman's terms.
The original works great
The original HTC wired headset comes as two pieces. The section connected to the handset has the mic and pause button on it. The earbuds that come with it are just standard 3.5mm stereo earbuds. You replace the earbuds with the jack from the cassette adapter and Bob's your uncle. I've tried it in my truck. I'm not using the cassette adapter but my stereo has an audio input jack on the front. (Same sort of thing) There is a little echo on the other end of the call. It's not bad though.
I have the original wire headset that came with the G1, it is a single piece unit. Can you post a link to your headset? I googled htc headset but couldn't come up with anything like you described.
edit: Found the wire headset for the AT&T Tilt. It has a mini USB plug and is a 2piece unit.
HTC changed the headset for the G1 after the launch. Originally it was just the headset with the htc proprietary end on it, then they released it with an adapter and 3.5mm headphones.
Unfortunatly for us Canadians, Rogers did not release the Dream with an adapter so we have to pay to use 3.5mm headphones.
I was recently handed a Nokia HF-510 to demo (http://www.nokiausa.com/find-produc...n-handsfree/nokia-display-speakerphone-hf-510)
It's a Bluetooth car speaker phone. The only down side was that the G1 doesn't support the Phonebook Access profile, so you couldn't browse your contacts from the speaker phone, but it's sound quality was excellent, and can be very loud so using it with the windows down while on the highway was very nice. The mic gets pretty good pickup, so no need to shout at the thing. I just didn't like the shape... kinda bulky, so stowing it away in the glove box wasn't really ideal.
Thoughts
Im pretty much is same boat as you..From ur explaination i believe you have this adapter..

...On any donut or cupcake roms..the mic signal seems to be rerouted back to tape deck as u said...buttttt...when i had a hero or eclair rom installed..it used the mic on the g1 itself..whilest still utilizing car stereo..so maybe its something in the software..or drivers..hope this helps
I have found that my only solution is JupiterJack or something similar. Just like the tape adapter that you're using, but it's wireless. You set the radio to a dead station and it picks up the signal from the JupiterJack. Now, mind you, I have only tested with WinMo so I can't tell you for sure if the G1 will use it's built-in mic, or if it will search usb for a mic signal and assume there is a mic present on the usb port. This is probably a 1.5 flaw, and is -definitely- a software issue because I have seen 'hands-free' devices like JupiterJack that specifically say they're only compatible with 1.6+

USB-C to 3.5 mm adapter - HTC U11 says "not supported"

Hi I found a pair of USB type C to 3.5 mm headphone jack adapters on amazon, and i plug it into the HTC U11 and before i even plug the headphones in it says this accessory is not supported.
I have headphones all over the place and I want a few adapters to leave on them so I don't have to carry one around with me.
Does anyone know of an adapter that is supported by the U11? Or a way to make the ones I have now work?

It's not working because there is no Amp/DAC in it.
Just the original HTC will work.
Unsure what you're asking me.
HTC only sent one pair, where can I get more that will work as I said I have multiple headphones

In Europe they are available on the HTC webshop.
Why you just unplug each time you want to swap?

Just because I have a pair of headphones in my truck, gym bag, at my office and at home. The ones online are cheap I thought for a few bucks I could have adapted all my headphones instead of having to carry one around!
Those cheap ones won't do. Buy them officially from HTC. Send the Amazon ones back for a refund.
Any idea on what options you have for spares in countries HTC does not not offer the adapter for sale (Australia for example)
Anyone want to trade their adapter for my headphones? I have never liked the earbud style I cannot get them to stay in my ears I would rather use the over ear headphones I already have but want more adapters
Adapter cost 13e and shipping 26e Wtf htc
HTC won't ship from UK store to US.... US is sold out. This sucks

Yes! Works fine with cheap USB-C to 3.5mm adapter. I use it on my U Ultra, that come with no adapter in package.
I bought the Pro key, that´s enable other type of output. Is this case. just select "Wired headset with Mic"

Do you know how this works. Is SoundAbout a DAC what exactly is it? I am asking because I got the Pixel 2 and it does not have a analog out like The HTC Bolt or HTC U11

It works. I can only suppose how it do it. Routing outputs. As U Ultra and U11 have analog output over USB-C, it route output to USB-C pins and you will have an analog output with analog quality. The DAC will works on board. I can say that quality differences between original HTC adapter with DAC and a generic with soundabout are minimal.
That´s it. It Work.
I bought this because I had an U Ultra before and it come with no HTC adapter and I love my 3.5mm phones.

Oh so then the U11 is different then the Pixel 2 then as it puts out digital out on USB-C only.

Maybe Pixel 2 doesn´t have analog output over USB-C or it´s blocked. Think that if you have speakers, you have an DAC onboard to convert digital to that analog speakers.
Have you tested SoundAbout and nothing happens? Even routing to different options? Or another adapter? on U11 an U Ultra I´ve tested on many types of adapters, including original Moto Z and all works fine.
But I don ´t have a Pixel 2 to test. (HTC and Pixels are rare on Brazil)

Which 32 bit DAC and AMP is used inside Huawei Mate 10?

As title says, they mentioned that Mate 10 has headphone jack which includes a 32 bit dac inside. I am curious to know which dac brand and model they used in their new flagahip.
Huawei Mate 10 Pro doesn't have a headphone jack, but I'm also wondering if it has that 32bit DAC.
Their slides say it has 32-bit for the Pro USB-C as well.

No, Mate 10 Pro does not have analog output (via USB-C), hence it does not have a Digital-to-Analog-Converter (DAC). Mate10Pro has digital output via USB-C. You need to buy your own DAC (either built-in into your headset, or other USB-C compatible DAC).
Now the non-pro model, that actually has a DAC, who knows?
The whole press event from Huawei was very obsfucating and didn't properly specify which features were non-pro OR Pro-model features. The same goes for the actual huawei.com specifications pages for these models.
Until the phones ship, are torn down and or rooted, we have to wait for the information.
I'm still hoping that the China model (6GB/128GB) of non-Pro Mate (with sdcard and 3.5mm headphone jack) turns up for sale online and has the nice features I'm hoping it has.

What's the source of this information?
The Mate 10 Pro box comes with a USB-C headset.
It also comes with a USB-C to headphone adaptor. Will that adaptor have the DAC then?
What if I use an adaptor with analogue audio pass-through. What DAC will it use then? I assume it will still use a 32-bit DAC on the pro? Otherwise digital only.
If it comes with a USB-C to 3.5mm adaptor, then the device has a DAC

The output is analog. Confirmed by a guy on youtube who connected the pro using the inbox usb-c to 3.5mm adapter to an external loud speaker.
The usb type c converter might have a dacs even the apple one has ,and so does the HTC u 11(I guess)
However they might be talking about the ones that might be integrated in their soc.
Don't get your hopes high though.Nothing can still beat the v20
We recieved the usb-c to 3.5mm audiojack, but Huawei told us it is wil not be in the consumer box.
However the usb-c earphones will be in the box
The Pro does have the audio adapter in the box.
What is confusing is what standard and how is Huawei implementing it. I have a pair of Razer Hammerhead Type C headphones. They work fine as you'd expect with the Razer phone. They work really well with my MacBook Pro and show up as USB C headphones, but plug into the Mate 10 and it says they are not digitally certified and dont sound great.
So does that mean Huawei need a headphones with a DAC built in to work ? or something else.
Whatahifi.com Huawei Mate 10 Pro
DAC: Digital to analogue convertor
Phone = Digital
Headphones = Analogue
Sorry to say but you have no idea of what your talking about.
A DAC is a Digital-to-Analog Converter. A DAC [Digital-to-Analog Converter] is a device that converts digital audio information (comprised of a series of 0s and 1s) into an analog audio signal that can be sent to a headphone amp.
Conclusion:
Every digital device has a DAC. Differentiation is made by the quality and amplifier power. I like AKM DAC's for example. Son unless you guys have discovered a way to build a phone with lamps you have listen to a DAC.
P. S. According do What a HiFI it has a High End DAC but the phone stutters heavely so I think I am going to return it.

Hi Gavin, have you tried in on Mate 10 Pro yet? wonder how does it perform as Mate 10 Pro doesn't have a DAC in the phone. Would you please describe more on the sound quality you encounter on Mate 10 with Hammerhead?
I am thinking to get one pair for my Mate 10 Pro..

DAC: Digital to analogue convertor
Phone = Digital
Headphones = Analogue
Sorry to say but you have no idea of what your talking about.
A DAC is a Digital-to-Analog Converter. A DAC [Digital-to-Analog Converter] is a device that converts digital audio information (comprised of a series of 0s and 1s) into an analog audio signal that can be sent to a headphone amp.
Conclusion:
Every digital device has a DAC. Differentiation is made by the quality and amplifier power. I like AKM DAC's for example. Son unless you guys have discovered a way to build a phone with lamps you have listen to a DAC.
P. S. According do What a HiFI it has a High End DAC but the phone stutters heavely so I think I am going to return it.

You have partially right, ther is not only a DAC solution, ther is PWN ! PWM is the best way to have a ****ing damn really good sound !
We have to know if the manufacturer use a DAC or PWM, and what is the chip used.
I personally use a "FX Audio D802". It is a Class-D amplifier, all class-D are PWM and do not use a DAC of course. And it sound really great, really better than a lot of expensive DAC+amplifier.
I personnaly don't love the Qualcomm DAC, i think it is really poor. I know some OPPO, ZTE and some others (Huawei/Honor ?) use AKM DAC but don't know wich one
Is anybody know what the chip used on the phones ? ... the only way to have good sound is to use a DAP.
Regards

Question Whining Sound Using USB-C To 3.5mm Adapter

I'm trying to figure out, without buying anything new, if the whining sound I hear when using the 3.5mm adapter is a product of the adapter or not. The whining sounds like the whining from a bad belt on a car. I actually thought it was my car at first.
Is anyone else using an adapter and also suffers from this?
The adapter I have:
Amazon.com

Disclaimer: 6 Pro here.
I'm using the adapter from Google and have not heard any whining sounds.
Try plugging it into something else (like your computer) and see if the sound remains?

Yes
It my just be your cars electrical system.
I remember the days. If you did notthing too isolate the alternator and distributor. You would hear the engine revving on the radio. Lol..

It wasn't present with my previous LG G8X using the same Aux cord I'm using now. The differences now are the Pixel 6 and the USB-C to 3.5mm adapter.

It seems that there must be something with the car and the adapter. Using the adapter with headphones and using the adapter with the same Aux cord and a soundbar does not create the whining sound.
Edit:
Yeah, it's something with my car and the adapter. Funny bit is that the adapter is said to have "super noise reduction technology". It would be funny if it's what causing the whining.

It could the car. Bad spark plug wires are a common problem.

When you get a chance some day. Try the setup in another car and see what happens.
Edit; I do not want scare you into thinking there is definitely something wrong with your car, but anything is possible.

It wouldn't surprise me if it is my car. Either way -- I'm gonna have to get another adapter.

It wouldn't be spark plugs. Virtually all cars made in the last 20 years have separate coils for each plug, not the old fashioned cap and rotor. They're shielded.
The part that makes the noise is the alternator, which creates a sinusoidal wave, both in the wiring and in em.
Alternators are present on all cars, gas or diesel.

Has to be the USB sound card (adapter dongle) or car analog wiring. The phone signal to the sound card is digital and can't receive analog interference.

It isn't present without the adapter so a guess is that the adapter is drawing power from the phone and passing it through to the aux cable? Though it doesn't seem to do the same with headphones or hooked up to a soundbar. I dunno.
Pixel 6 usb type c supports only digital audio so all conversion to analogue signal is made by the DAC (digital to analogue converter) in the cable. This is why cheapest type c to 3.5mm cables without DAC do not work at all. It is quite strange but maybe just this cable do not play well with your car.

The phone's power is DC and clean from the battery, so it won't be supplying a sinusoidal wave. The noise CAN'T come from the phone. The dongle or wire is picking up RF or unstable electrical *FROM THE CAR*.

Gotcha.
So previously, the wire alone, didn't pick up the noise. What about the adapter, do you think, could be picking up noise? And from what? The aux jack is in the center console. There is also a USB port next to it. At this point it's all academic. I'm going to buy a Google or Apple adapter and see how it performs.

Its hard to tell. Depends on whats in it and how it is wired. It may also depend on the car's audio wiring -- if the car is wired for single-ended inputs, then the shell may be attached to chassis, which may carry noisy signals to the audio dongle.
It seems to me that the most likely cause is some component in the audio dongle being unshielded and allowing RF into the pre-amp circuit. An easy thing you can try, and I know this might sound a bit wacky, is wrapping tinfoil around the audio dongle to see if that has any impact on the noise you are experiencing. If it does, it would confirm this theory.

That sounds like a fun experiment. Heck, maybe I'll just go with the home-brew solution if it works. I don't care if it looks crappy.
