[Xiaomi Mi A2 Lite Questions & Answers] AndreyTsvetkov:
Hello there fellow Xiaomi users, I have a problem with my Bluetooth earbuds and it's driving me insane! I hope you can help me out. When I connected my newly purchased bluetooth sony earbuds (the model is WF-XB700) I noticed that the volume was really low, maybe 50% less than it should've been. I was perplexed, but had a couple of quick ways to determine the problem. I connected the earplugs to a Iphone 8 and they worked just fine, 100% of their capacity. Then I connected my Xiaomi Mi 2A lite to some other bluetooth headphones (model Pioneer se-ms7bt) and they also worked as they should've. Then I connected the earbuds to a Xiaomi Mi A3 and to my surprise, I could also detect the Low Volume Issue there too! So, it must be something Android/Xiaomi related.

Then I went on a really energy draining odyssey on google to find a solution. What I did find was, firsty, that it was a known issue and secondly, that the myriad of solutions presented did not help me at all. This is a list of the things I tried, some of which spawned problems too :

1) Disabling absolute volume in developer settings.

2) Tinkering with all the options in the develper option - even the following (I will copy paste in from an other thread , which according to many people has worked :

Enable Developer Options (options -> system -> about phone -> click build number 7 times)

Press back

Go to settings, and search AVRCP.

Click on Bluetooth AVRCP Version and ensure it is on 1.6.

Next, search for Absolute

Select Disable Absolute Volume and turn this toggle on, if it isn't already.

Unpair all Bluetooth devices. Restart your device. Pair the devices again. To the right of each Paired Bluetooth device in the Bluetooth settings page is a gear icon, go into each device and turn off the Phone Calls toggle, leaving only Media audio enabled.

Exit settings, connect to the Bluetooth device, start playing something. Increase the volume using the volume up button and rejoice as the volume goes as loud as you need!!!

3) Putting the volume up in the Sony Headphones app. - So, officially the app doesn't support the WF-XB700. There are two options for detection. The first is a list of the supported devices (mine is not there) and the other is a ,,detect via bluetooth''. Tried the second option but it doesn't work

4) Increasing the volume on the physical buttons on the device. Mine are earbuds and have only one button for on/off

5) Ensuring the eartips are tightly fit in my ear.

6) Making sure the earbud isn't blocked by anything.

7) Resetting the phone

8) Changing the Region - This I actually did not succeed in doing. It turns out that the option to change the region has been removed. If there is a way to do it, please inform me.

9) Trying all the volume booster apps in the store.

10) Restart or enable and disable airplane mode

11) Forgeting and pairing the device again

Could the bluetooth version difference be the problem. Mine is 4.2 and the buds are 5.0. According to google there should't be a difference regarding the sound volume/quality, only range and connection strenght. Please help me, I have wasted more than five hours already and I ran out of options to try. Thanks in advance !
