What's your price range? Wired or wireless? Do you want to listen to both at the same time?

I wanted to be able to hear ps4 sounds and Discord during times when I played my ps4, so I bought a Logitech G933. I use it wirelessly with the ps4 and plug it directly into my phone via the aux cable. It has the ability to mix the sounds so it plays both at once. I like it well enough. It lasts a decent amount of time if you turn off all the lights. Comes with a super long USB cable in case you need to plug it in. It's expensive, though.

I find the quality of the discord mobile app depends more on the phone. It hated my old G2 but works perfectly fine with my S7, and oddly enough, my rooted cheap amazon fire tablet.

Vent idk. I haven't used vent since like 2010.
