Does the Roku Voice Remote Pro (2nd edition) have a headphone jack?

Sorry, no.  If you want a headphone jack you'll have to get a 1st edition VR Pro.  https://www.roku.com/products/accessories/roku-voice-remote-pro

Hi, Odnar-S 

Welcome!

I appreciate your inquiry about the availability of a feature on the headphone jack with Roku Voice Remote Pro (2nd Edition).

As advised by @makaiguy, the Roku Voice Remote Pro (2nd Edition) does not have the headphone jack and is only available with its previous version.

In the meantime, you can use the Roku mobile app remote feature which has the headphone mode. For more details, you can visit this support article on How to use headphones with the Roku mobile app for Headphone Mode

Hope this information helps, and keep us posted if you have further questions or clarifications.

Thanks,
