Using a FiiO Q5 headphone amp connected via bluetooth causing the music to stutter and also plays a little faster

So I am using a FiiO Q5 headphone amp so I can increase the volume and other sound enhancements as the sound volume is a little low on the Sony Xperia 10 Plus Dual SIM.

However since using build when connecting via bluetooth the music is constantly stuttering and plays a little faster also. I tested these using the balanced socket, unbalanced socket and bypassing the pre-amp socket also. All the same results each time.

When connected via the usb port the sound plays normally and correctly however it drains the power from the mobile quickly so its not an ideal workaround.

I tested this via the normal native music app ‘Media’ and also via VLC which I installed both had the same results via bluetooth.

When I connect Sony WH-1000XM4 headphones to my mobile via bluetooth none of those issues are encountered.
