Razer Nari Essentials on PS4 using Synapse

Hi!

I just bought the new Nari Essentials headset and plan on using it on the PS4. The amount of bass however is to much for me in game and I would like to tune this down.
Q1: How do I save the settings I change in Synapse on my laptop to my headset (and is this even possible) so that i hear the ''custom'' settings ingame on my ps4?
Q2: I would also like to know whether or not the initial sound of the headset when connecting it to the PS4 (before doing anything with Synapse on the PC) includes THX. So basically, in case the headset can't save any settings from synapse, will I have acces on the PS4 to THX sound?

Thanks in advance!
