Bad quality/low volume on Bluetooth headphones

ZF Model: ZB602KL
RAM: 4G
Firmware/APP Version: 059
Frequency of Occurrence: Always
Rooted: No
APP Name: Bluetooth aptx
Hi,
I recently updated to the 059 firmware and noticed that Bluetooth sound quality significantly decreases as well as max volume is too low.
I am using headphones that support aptx (I see notification that it is turned on). I am comparing sound using same apps/same file on my Asus phone, old iPad and Windows laptop. Both quality and max volume are way worse on Asus phone which was not the case before.
What I have done so far:
- tried to 'Disable Absolute volume' in Dev settings
- reset Bluetooth/wifi settings
- reset all apps settings
Still no luck. Moreover it also sounds as if left/right channels are not balanced. And it also sounds that switching Aptx on and off (in Bluetooth settings) does not affect sound quality at all - therefore my guess would be that aptx is not working (although shows to be active).
I was trying to see HCI log - but it's not working - no log file is produced to further investigate the issue.
Thank you in advance for your help.

We are sorry to hear that you are having this issue
As we did not face this issue after duplicating, Could you describe more clearly?
Please help to checking with another bluetooth device.
If the problem exists, let us know which bluetooth you are currently using and on which bluetooth device you duplicated the issue.
Thank you:)
1. My Zenfone vs iPad - I listen to the same songs using same applications (namely SoundCloud and Apple Music).
2.My Zenfone vs windows laptop - I use same flac file with VLC player (that is available at both platforms).
Both comparisons show very low volume of my Zenfone compared to other sources and lower sound quality.
How can I see Bluetooth log so I can provide you with further information ?
Hi,
Can you advise how do I get output from Bluetooth HCI snoop log (available at Developer options) since I can't find where its output file located.
Thank you
Hi uspenskiy.ua
After the relevant team's confirmation,V059 no change BT related factor.
BT has compatibility to every device, recommend to provide BT device model to help clearify issue
HCI log was hide by system from Android P, need getting from bug report.
We recommend you recording unit log + bug report to check if Aptx workable.Please help to check the message in box and kindly respond if possible.
Thank you:)
Ok, before doing that I want to ask last question:
I recently got the idea that some sound settings could have been modified by Equalizer app (recently installed several) - like Sound Enhancement settings.
If I do factory reset - can you confirm that sound settings would also be back to factory set settings?
Thank you
Hi uspenskiy.ua
Equalizer apps would affect sound quality. This is considered as the third-party app issue.
We would suggest you bring sound settings to their default factory and help us clarify whether this problem is still appearing
Sorry for any inconvenience this may cause.

As I mentioned earlier, all was great on oreo.
So I bought tws headphones, sound is like not all its potential, it's like phone try to cut all frequencies to the same level. And again I tried them with my old phone, and there are no drops or any cuts, and sound is much louder. Pls Asus bring normal Bluetooth back.
I can just add, that all Bluetooth quality related options in engineer menu (or developers menu idk correct translation), aren't changeable, if i change smth, and go back, it returns to default. Maybe this will help you to solve this problem?
No sound enhancers are in use.
P.S it's already 5 months, that I can't use my Bluetooth speaker, and now the same will be with headphones, because sound quality is shit. Pls fix this asap.

Hi,
I am facing the same issue on my ROG Phone 3.
The volume controls seem off and I have to go beyond 50% to even hear anything.
I am using bluetooth earphones -
