The new patched 64bit file worked.
Tried 486 one only.
Here is Bluetooth log. (Upload was too slow at given link so sending GD link)

Yes, it worked, the bitrate is 485 kbit/s. Did you hear any cracklings or interruptions?
The audio you played is of low quality. That's probably an MP3 ~160-192 kbit/s?

There is no crackling. Yes mp3 was of low quality that I tested.
Yet sound seems improved. I will need more time to get proper impression. I will post later here.
Also I have spread the word in few telegram channels.
Thanks

Patched version has been added to the second post.
This sound enhancement is only for SBC codec, it won't do anything with aptX. You should disable aptX to test patched version.

Hello
I have 1more ibfree sport headphone that supports AAC HD codec only with apple devices as company has mentioned in their site. (https://india.1more.com/collections/...hones-with-mic)
As in your post you have mentioned 1more ibfree, that support aptx codec .
My headphone is newer version of ibfree series.
So the problem is in developer setting I can't change to AAC from SBC codec.
It stays to SBC only so I think I can get help from here from you.
So here the link to those .so files

Please capture a dump and upload it to https://btcodecs.valdikss.org.ru, you'll see all codec information which the device supports.
And by the way, patched libraries for Le Max2 Oreo are already in the second post, give them a try.
