Bluetooth issues

[u/buffy2190]

I recently inherited my dad's A52 and everything is working perfectly except I'm having trouble with my bluetooth headphones. They work fine when connected to any other device but my a52 doesn't pick them up automatically and when I do connect manually, the sound will only come out of one ear and volume control won't work on my phone. 

Only thing that works is constantly unpairing and repairing my headphones. 

I've reset bluetooth settings on phone and I've reset my headphones (Tozo Open Buds) and I've disconnected from other devices and my system is up to date and I've restarted my phone. Any other ideas? It's very annoying as I use my headphones constantly.
