Do these work with the kbear ks2? if not, is there any that do?

Hi Cashews, Thank you so much for your message; unfortunately, KZ Bluetooths are not compatible with KBear products, but you might be interested in these type, KBEAR S1 Bluetooth 5.0. Kind regards, ~Gabriel KC Island

How long to the bateries last without putting them back into the box?

I have gotten 7 hours of use out of these without the charging box. I did not see the remaining battery life at the end of the 7 hours but the headset was still going with no distortions.

Hola, ¿sirven para los kz zas?

Si, pero debes comprar la versión con pin c

what ipx rating are these?

According to some listings they are level 5 and this one says they are sweat proof so you are probably good wearing them in the rain or while sweating but I wouldn't go swimming with them.
