Can I use the adapter to pair 2 Bluetooth headphones?

Yes, you can. You could check the above video for how to pair two bluetooth headphones with it.

I just got these it connected to my PS5 but i can’t talk to friends online why is that?

Do you use the coming mic or use the built-in mic of your headphone? If you want to use your headphones’ built-in mic, double click the Multi-Function Button on the C81 and enter talk mode. The sound quality will be limited in this mode. This is due to current Bluetooth technology restraints. You could check the above video for how to set the sound setting of the PS5 too.

How can I get good sound quality with PS5?

To get good sound quality during a chat, use the included mic. Plug the mic into the PS5 controller. Now you can chat with your teammates and listen with your headphones at the same time. In this way. Your headphones' built-in mic doesn't work. If you want to use your headphones’ built-in mic, double click the Multi-Function Button on the C81 and enter talk mode. The sound quality will be limited in this mode. This is due to current Bluetooth technology restraints.

Would this work with my razer kaira rz04-03980100-r3u1?

Unfortunately, the C81 dongle is not compatible with your Razer Kaira RZ04-03980100-R3U1 headset. The Razer Kaira is not a Bluetooth-enabled headset and can only be paired with its included dongle for wireless use. It cannot be connected to a different dongle, including the C81.
