In a similar dilemna myself. and stumbled here from Googling…
Two differences are that I own a PS5 already and that I’m a tech tinkerer. However, on the latter note I’d be looking for as tinker free xperience as possible for this one use case (the quick gaming sessions)…
Bookimarking to read the other replies…
For me I was initially going Portal for the simplicity reason (and to not have something where I can tinker too much that it becomes a chore to play… ), however, Bluetooth was the deal breaker for me for a cheaper streaming device (albiet with a good screen and controls etc.). If I have to buy headphones on top of the cost it ends up getting closer and closer to a Steam Deck which can also stream… Its not as sexy I guess but its at home anyway!
Of course. Dollar for dollar wired IEMs will always sound better than their wireless counter parts (obviously within reason, wouldn’t be comparing low end IEMS and top end wireless ear buds).
With that said because the device is hand held and portable it was a deal breaker to take away the ability to use non Sony specific wireless earbuds.
