now this is a great update that I waited for since I saw the audeze presets.
does this also work with ARC (phone app) and DAPs that are a Roon endpoint? (im using neither at the moment)
My MacBook shows the headphone filter correctly under âsingnal pathâ but my iPhone (14 pro) just shows âunknown filter â , has someone a quick fix for that ?
PlayStore tells me the Android ARC Beta is full 
This is interesting because I went through the process of manually creating Parametric EQ settings previously using the same measurements offered by OPRA for my Focal Clear MGs. Iâm noticing more punch/volume from my manual EQ settings vs the same auto EQ settings offered by OPRA.
I made no adjustments to Headroom though, but I assume this should still be active with OPRA, correct?
I am new to all of this, although had previously downloaded a filter for my headphones. Do most people use a filter AND parametric, or then turn off parametric. I know our ears should decide, but I am curious about common usage.
You and use either headroom or volume levelling but you should use one or the other to avoid clipping. Personally I go for volume levelling as it makes it a smoother experience on headphones without the massive volume adjustments that you get between older and newer mastered material.
You can, no rules on thisâs my advice is Kiss, unless your creating a house/ear sound on top of it if for some reason. Stick with one or the other or both and use works best for you.
PEQ canât adjust as finely as correcting using FIR filters especially in the bass region. I prefer to use FIR fitters over peq. I get mine of AutoEQ, no idea why Roon canât adopt this which is the defacto repository already for this stuff rather than basically do the same thing but make it closed and give it another silly name to further confuse users. But something is better than nothing I suppose, but I am not for closed shop solutions.
One of the notes said they want to be AutoEQ plus other sources too. Donât know why they would need that (and i know little about the topic, just reporting what i read i think on their GitHub)
I agree with everything. But this is already a nice feature to have. And Iâm sure many people will rediscover their current headphones, especially the crowd that is more likely to run a Nucleus because itâs simpler 
Here is me hoping we get FIR filters and 3D audio solutions in the future and atmos support
No. I donât find it. Is there anything I can do?
Are you using Early Access?
I agree its a good feature, i use FIR from AutoEQ though so heres hoping they do include that but ARC doesnt have the grunt for that so maybe not.
Not sure why you would be baffled as they stated in the initial post that they have
So this is a user requested feature they are trying to meet. Not sure why that would be surprising or baffling. LOL
There are those of us that have several headphone stations around the house that these EQ settings will be useful for.
It may be cumbersome, but the feature does work on portable rigs, too.
You just have to plan ahead and set the filter or your saved EQ before you go out.
If you save the Headphone EQ as a Parametric EQ and then add several parametric EQs for your different headphones you can access them all and enable/disable them from the remote app on your phone/DAP etc.
On win10 PC:
It would be nice if we could rename (or add a description to) the Parametric EQs so that we could select the correct one more easily and the remote app. Right now you have to remember which one you applied which filter to. Same thing for the headphone EQ. It would be nice if it indicated which filter was applied outside of the muse page.
Thank you. Sounds interesting. But is it useful for my Focal Utopia headphones, if I already have a headphone amp (spl Phonitor X)?
Thank you
If youâre happy with your EQ, no benefit.
I have my headphones EQâd in Roon, but if I were to get new headphones that needed EQ then OPRA is there.
This is a good initiative by Roon and can be implemented by open source applications, hopefully weâll see an LMS plugin before long.
Do you feel the headphones need EQing? I only EQ 2 of my headphones, the rest donât need it.
If so you can add PEQ in Roon muse already outside of OPRA. OPRA makes the whole process more convenient.
Iâm unaware of the device you mentioned which may also be able to have PEQ settings added.
Trying to add a 10 band PEQ on a phone is a painful experience, digging out the laptop to add a PEQ preset and associate it with endpoints is a one time process.
Selecting the profiles once set up can be done via the mobile app.
Ps my EQâd headphones are all used at home, many people in multi occupancy accommodation cannot use speaker setups at home, nor can people who donât have the space.
Itâs not the case that itâs more often than not related to mobility, I see people walking round with Bluetooth headphones mainly, not Focal, Meze etc that I suspect most people use in their home and which they may wish to EQ.
This is a most exciting and welcome feature for headphones users.
But is there a difference between Opra and loading a downloaded zip answer file from the community into Convolution?
I do notice the volume level is not degraded; of course, it is a more elegant usage scenario.
I actually think itâs a pretty nice feature and it works nicely over here!
Just one question: Trying out some of the EQs, Iâm noticing a volume difference, so it seems that headroom is already built in and does not have to be set additionally. Can someone confirm?
For my purposes (a number of headphones that stay connected to specific endpoints for long periods of time, but which do rotate 1-2 times per year), this is great. Thanks for doing.
I agree itâd be nice if there were a suboptimal but possible way to interact with a feature this simple (just pick manufacturer / model, not define your own EQ settings) from the phone app, but for my purposes itâs not a killer. Clearly for some folks this is important. I am in the camp that would like to be able to do more things rather than less from my iPhone (ie, smart playlists, simple track editing / identification) but I respect the choices that are made. I do think that there is a measurable segment of users who are ~99% phone as remote, and for them these phone limitations must be a real pain.

ARC seems good to me with OPRA.
Although my first use with standard Roon for Ferrum WANDLA and HD800S results in OPRA reducing volume considerably.
At first I thought it was really muffled, but turning volume back up I think itâs back where it was.
It felt the equivalent of a -12dB headroom adjustment and so contrasting with the no OPRA option that itâs really hard to A/B test.
Could be great for ARC, but without a decent way to test Iâm not sure I want to just try it.
Will try MojoPoly later.
