I've got other 2 non oneplus passive adapters and both require turning OTG on.
USB-C to 3.5mm adaptor

Correct. I don't have any kind of mods whatsoever, and I'm completely stock with the bootloader locked.So you never have to toggle OTG mode (a stupid OnePlus addition, they should've just left it enabled like other phones) to use that adapter, just plug it in? That would suggest that they might've removed that requirement.
You haven't done this by any chance?

It takes about 2-3 seconds for the adapter to be recognized and start outputting audio to it, even if you have music playing and plug it in after.
Edit: What's weird is I can plug in my Meenova SD adapter and it's also recognized automatically. I never touched the OTG switch since I got this phone now that I think about it.

I guess I'll just have to test it myself when the other adapters arrive. I've already ordered a few so that I can keep one permanently attached to each pair of headphones I use.
Soditer Pixel 2 Headphone Adapter,USB C to 3.5mm Adapter
Edit: I initially tested this adapter with Spotify downloaded songs with a "normal" bit rate setting. I changed the Spotify "Downloads" settings to "Very High" and repeated the sound quality test with this adapter and am very impressed. It seems equal to an inbuilt 3.5mm head phone jack that I had previously used. I'm more satisfied with this purchase than when I initially wrote this post.
Just received a OnePlus 7 Pro Nebula Blue two days ago. I tested the "Soditer Pixel 2 Headphone Adapter,USB C to 3.5mm Adapter" with a OnePlus 5 and it sounded equal to the straight phone jack connection. I bought this adapter because it boasted " sampling rate (up to 384KHz/32bits) along with different songs, usb c to audio jack can drive stereo headphones up to 35mW/32ohm" and included "Realtek chips/DAC". Plus one reviewer said it worked well with his OnePlus 7 Pro.
This adapter also works well with my OnePlus 7 Pro and coincidentally has a matching metallic blue finish. I'm rooted (TWRP, Magisk) and have Viper4Android (V4A) installed. In the V4A UI, you'll need to enable "Master Limiter" in the USB headphone settings to get V4A to process the audio but from there on your golden.

I just received this: https://www.aliexpress.com/item/USB...e-Cable-AUX-Audio-For-Xiaomi/32952948600.html
I don't know if it's due to improvements in 9.5.8, but I don't need to turn on OTG or anything to make it work.
Just plug it in and it works perfectly, to both charge and listening to music. Though I'd say it'd be a bad idea to actually charge through this, would only rely on the charge port in case of emergency situations.

Could you measure the charging current while playing audio with Ampere or a similar app? That would be really helpful.
Sure, you can see the comparison of the warp charger directly connected to the phone v/s the warp charger connected through this adapter v/s music playing through the adapter and warp charger connected.

But you are still getting ~1.3A charging current. That is more than some of the other adapters which had ~500mA. Thanks for the screen shots, that was helpful.
For those of us with balanced IEMs/headphones, I'm waiting for this one. It has a USB C>balanced amp 2.5mm output with an AKM 4493 DAC. 32bit high res and DSD.

I tested the adapter included with the Essential PH-1, and it worked straight away. $10 on Amazon, so could be a good option for those that prefer the braided cable.
Anyone tried one of those audio adapter with audio and mic? Like for calling
These work fine without toggling the OTG toggle. Could be due to the change in 9.5.8 though but who cares. Regardless, the quality of the adapter I ordered feels really high.Are you sure that turning on OTG mode is required on the OnePlus 7 Pro when using passive adapters? The post I quoted below seems to suggest otherwise.
I bought a OnePlus adapter but it feels pretty flimsy due to the thin cable so I was looking at buying a few Ugreen ones to use instead. Having to toggle a stupid setting every single time would be seriously annoying though.
So you never have to toggle OTG mode (a stupid OnePlus addition, they should've just left it enabled like other phones) to use that adapter, just plug it in? That would suggest that they might've removed that requirement.

Hello can be used for making or answering phone calls or it's only for music or video listening?
How is the overall impression after 3 weeks you are owner ?
Any negative aspect that you see or everything works fine?
Thanks in advanced .
I've only had one call while listening to music (the adapter plugged in) and it worked identically to a 3.5mm earplug. The microphone is in the phone so no change there you just have all audio calls, music ... etc through your earpiece/headphones. I've not had any issues and would still recommend this specific adapter as one that works well with the OP7Pro all around and its handling of high bit rate audio sources. I personally, don't do anything Dolby ATMOS related so can't comment on that audio type.
For those people who have an Amazon UK Account the Soditer Pixel 2 Headphone Adapter,USB C to 3.5mm Adapter is available for those interested.
The Huawei USB-C to 3.5 mm Earphone/Headphone Audio Jack Adapter - White from Amazon UK is a steal at £3.95 and works fine for both audio and audio/mic. If you can source something similar locally you should be fine.
Curious do sound mods work with the adapter?
Not sure if it's a feature currently but I typically increase voulme with EXKM (if feature is implemented on custom kernel)
Is this still a possibility when using adapter?

So after my Apple audio adaptor didn't work I tried some from Aliexpress.
And I can confirm that the red one https://www.aliexpress.com/item/32960752995.html works for me too.
https://www.aliexpress.com/item/32976741093.html that one works also, but i'm a bit afraid because of the force on the USB-C port because there is nothing flexible until the headphone cable.
https://www.aliexpress.com/item/32986252481.html that one I can't recommend. It does the job of transmitting music and charging (around 1A), but you hear medium loud interferences when charging.
All three adaptors worked without enabling OTG, but maybe this relies on the 9.5.8 update.
