Hi Sbogdano,

yes, the unit supports multipoint connection function. If there are Bluetooth connections between 2 devices and the headset, another paired device can be connected via Bluetooth. You can find more information and instructions on our support page. You can also learn more about customers' experience with iPhone on the community page.

The quality is very good. Noise reduction incredibly good.
Have used them with the iPhone 13 13Pro and 14Pro. As well as with the PC and laptop.

But never used multiple devices at the same time.

Therefore, my statement only refers to the quality, which is very good as described.
