Hello Sheran, 

I´m not familiar with the H90 I´m afraid. The HW530 is a quick disconnect headset so there are numerous adapter cables you can get to ensure it works with your device. 

The compatibility checker provided by Poly/Plantronics (Link below) can help you find the appropriate cable which we will sell. 

You can choose whether or not you are looking to connect to a Deskphone, Mobile, PC, or more at the top of the page. From there you make the selections needed to determine what adapter you need.

Thanks
