Sure the thread title is pure click bait but there is some underlying truth to it, namely since Opra was introduced many months ago there doesn’t appear to be any additional headphones added to the list of headphones with headphone EQ curves.
For example the FiiO FT7 and FT13 headphones plus the Fosi Audio i5 headphones and the Fosi Audio im4 IEMs are nowhere to be seen. So is Opra now effectively dead and do we need to go back to the pre-Opra way of adding headphone/IEM convolution filters to Roon? Or will Team Roon start to take Opra seriously and add additional headphones to the Opra database? Thank you.

OPRA is a community maintained project, that can utilize AutoEq measurements*, and, it would seem, isn’t maintained by Roon. So, it looks like no one is updating the repo.
*AutoEq has some updates that could be ingested by OPRA.
“community maintained” aka the user pays AND still has to do work. I don’t know about you but when I PAY it’s because someone else is doing the work. When I work, I expect to get paid, not pay. In other words, I’m not a fan of all this tech inspired community nonsense.

That’s a rather cynical interpretation. Would you say the same of other open source projects where individual and collective effort is gifted to anyone who may benefit from someone elses effort?
As long as headphone by companies like Dan Clark , Audeze , Meze , Denon , Yamaha get added and updated . I wouldn’t expect every Chinese headphone and in-ear made to be added to the database.
Well, at least it would be nice to hear someone comment on how updates should be happening.
I’ve also been looking for some well known headphones that are not in the library.
It’s open source, but created entirely by Roon staff. The initial values were added by @brian. He then imported a number of oratory1990 values and nothing has been further updated for over a year. Basically an open source repository has been set up by Roon without a clear strategy as to how this will be updated.
Adding to a GitHub repository is not like uploading an image to Valence (another Roon community led venture). I suspect that it requires technical skills that are beyond the general Roon user base.
The answer to this issue is obvious. A member of Roon staff should be tasked with updating the Opra database when AutoEq or oratory1990 update their databases. These updates don’t happen that often and so this solution is entirely achievable.
I totally get where @Jazzfan_NJ is coming from here.
Drop a feature into the mix, which entices headphone listeners, but then isn’t maintained in house by Roon themselves which could/should be paying for someone to add and update the list of supported cans.
Is the Roon user paying for this additional feature?
Yes, and every time Roon adds a new feature the user is paying for it. I know some will see a new feature as being a fee add on. It can only be seen as such if the feature can be disabled. Opra is baked in even if not used.
This is one of my gripes with Roon. Features that cannot be “fully” disabled like a Lyrion plugin can.
Do these features, if not actively used affect the operation or SQ (obviously not is not used ). No, but they are there and some users may not want these features and were happy before they were added.
This is just my viewpoint.

You probably know the response to this excellent suggestion. There needs to be a request in Feedback > Feature Suggestions.
From the repo …
The OPRA project started at Roon Labs, the makers of Roon and Roon Labs continues to contribute by maintaining the repository, producing vendor and product artwork, and assisting with data ingestion and cleanup.
But, I agree, no recent updates headphones added (see below.) If I userstand correctly OPRA aggregates headphone EQ from other projects, with a permissive license, for use with Roon. It never added headphone EQ for new products. My guess is that Roon won’t do anything without a pull request (and a lot of people won’t know what this is.)
However, as far as I can see, the repo is being updated. For instance, AutoEQ had updates 5 months ago, and OPRA 4 months (with some commits a couple of weeks ago.)
Ultimately, headphone EQ will only be prepared via wider open source community efforts if people have the cans and do the work, or manufacturers do it for us. Roon or anyone else for that matter would need every pair of headphones to do this.
I think the updates are to do with graphics and written headphone information, not actual values. As far as I can see, no additional headphones have been added for over a year.
I’m not suggesting that Roon staff measure headphones, I’m suggesting that they update the OPRA database at periodic intervals by drawing the relevant information from AutoEq and oratory1990.
Without wishing to sound unduly cynical, I don’t think anybody really takes seriously the stuff that is posted as Feature Suggestions. I mentioned Brian in my post and so, if he wants to, he can act on my suggestion. I shall not hold my breath!
Oh WOW is going to “gift” everyone who uses Opra a Roon subscription!! NOT! Because is not an open source project but a for profit company. And I don’t any work for a for profit company without getting paid. This includes uploading to Opra and MusicBrainz.
There are a vast number of headphone measurements within AutoEQ. Roon have taken all that data and put it into Opra.
Should Roon contribute back to this library of tested headphones? Yes in my eyes.
Making money from volunteers hard work……..it could be seen this way.
I do wonder what you get for the monthly, annual & lifetime subs
Just putting my thoughts and views out in the open.

I think you’re mistaking MusicBrainz for Gracenote. MB is an open, not for profit organization. Likewise, AutoEq and oratory1990 are open and not for profit. This is why OPRA can consume their data for everyone’s benefit.
Previously, it was possible to use the data, but it was necessary to import convolution filters. Roon has made this process easier, but it is still dependent on volunteers contributing headphones or measurements to AutoEq etc.
Could Roon do more to support these projects? Yes, I think so. But this isn’t a requirement of a permissive license. I get a lot of benefit from MusicBrainz, and I’m happy to contribute my time so others don’t need to put in the effort.
I appreciate your time given here. There are a number of good folks who do this
Edited by user: Doesn’t Roon have an employee who’s job it is to amend incorrect metadata? Is it not this persons responsibility to ensure the metadata Roon brings is up to date, correct and valid?
And money is fungible. and it would appear that Roon is using the resources provided by non-profits for profit, unless Roon is compensating these organizations with some form of payment. And I do believe that Samsung Electronics (Roon’s parent company) has the necessary resources.

As I already posted, this is not a requirement of open source licenses.
You’ve already made your position clear about contributing to MusicBrainz, even though you are a beneficiary. What’s the difference? You’re free to use the data, and so is Roon.
). No, but they are there and some users may not want these features and were happy before they were added.
