I’ve tried many different configurations, as experimentation is part of the joy of audio enthusiasm, is it not? But I’ll lay out my current configuration and why I went that direction:
I have an Arctis Pro Wireless and I use its station as a DAC, more or less. I have it plugged into my PC via USB, and it has a 3.5mm line out and optical out that outputs audio at the same time. I have the 3.5mm line out going to my Avantree Oasis, and the optical out to my speakers (I know this seems backwards but more on that later). So to lay it out:
PC > Arctis Station 3.5mm line out > Avantree Oasis > BTR3K > 58X headphones
PC > Arctis Station optical out > Vanatoo T0 speakers
PC > MH670 USB Dongle > MH670 (using their proprietary 2.4GHz wireless)
I know this sounds like a disaster for latency when decoding/encoding/decoding/encoding/decoding is part of the chain, but believe it or not, I’ve found optical to the Avantree Oasis to have more latency, for both optical out of my Arctis Station and my motherboard onboard audio. I feel like it shouldn’t because it should be digital signal to digital signal. Besides, using 3.5mm line out to my speakers created a noticeable hiss when there’s no audio. So that’s why I have it switched around.
But yeah with this setup, audio goes to both my speakers and headphones at the same time (have to mute my speakers normally but this provides a convenient test), and it’s evident sound comes out of the speakers first, then the headphones. Sounds sort of like an announcer on stadium loudspeakers with that echo delay, literally <100ms but noticeable.
I’ve tried onboard audio as well, both 3.5mm out and optical, using the bypass feature with the Avantree, the works, and this setup is what I settled on when prioritizing low latency and convenience.
It does! All of bluetooth actually transmits at the 2.4GHz range, but it is a digital signal where encoding was actually never intended to be latency-free. This is where the variety of codecs come into play and why there’s such a wild difference in latency and quality. The way that most wireless gaming headsets go about it is typically their own proprietary encoding that is optimized for as little latency as possible. So it’s like… I know the tech is possible, just curious if anybody made anything like what I’m looking for, you know?
So that’s the thing. I’ve somewhat settled on the fact that AptX LL works well enough that I typically use it for gaming while on comms, and most of the time I go by with little issue, not noticing the delay, but occasionally, like I mentioned with navigating FFXIV’s menu, I’ll suddenly notice the sound effects don’t line up quite right with my mouse clicks. That’s it really.
