I don't have top of the line earbuds but the Bluetooth latency kills me. It's just enough to be really irritating and rhythm games are infuriating. I've been trying to find 2.4ghz dongle type but none I could find seemed any good.
Just this week I got a pair of Edifier W240TN earbuds. About $70 on Amazon. The sound quality is good (I’m not a complete audiophile but I’ve had some crappy earbuds in the past…these are better than any I’ve had). The noise canceling is okay, not as good as my headphones, but that’s okay.
But I realize that’s not what you’re asking about. They have a “low latency game mode”, advertised as “80 ms”. I was able to pair them with my Steam Deck fairly easily and had to change the button assignment in the app ahead of time, but I tried the game mode and it actually worked pretty well. I’m pretty sensitive to audio latency, but I was impressed with them. They might not cut it for high end play on rhythm games, but swinging around on Spider-Man felt good to me. I watched a cutscene and the dialogue matched up well enough to not be distracting. They might be worth a look.
Headphones that support AptX LL made a big difference for me. I picked up a cheap set on Amazon that work well but they have really terrible battery life. I may replace them now that I know AptX LL works pretty well.
I tried several other pairs that only supported SBC and AAC and the latency was irritating, even for the slow paced games I play (like Powerwash Simulator).
Edit: This is the pair I got, they've released a new model so maybe it's improved but I certainly don't get 20 hrs on a charge.
+1 for soundcore, they're so good. I was going to recommend the soundcore p3, but I don't have a steamdeck so idano if there's reasons those are better, but I've been super happy with everything soundcore. I have 2 of their Bluetooth speakers too, one for work and one for home.
Not what you asked for and you're not a fan, but if you're frequently finding yourself using your Deck at times you need to keep your ears open, I'd also recommend also finding a set of Bluetooth bone conduction headphones.
Of course it's not the best sound and there's a little lag, but I find myself needing to keep an ear on the world while using my Deck more often than I thought I would back when I got it. They've been really handy for a $50 Amazon pickup.
I have used Jabra 85ts with the steam deck and have not noticed any latency issues. I do have to manually reconnect them after i put the deck to sleep. Otherwise they're the best wireless earbuds i've used.
