Great Video Showing (audibly) The Differences Between Wired, Aptx, Aptx Low-latency, And Standard Bluetooth Speed...

For all those wondering about latency/delay, and how "fast" standard Bluetooth (SBC), aptX, and aptX-Low Latency actually are, as compared to a "wired" connection -- here is a great video which plays an audio/video clip through two speakers simultaneously...

FIRST, they play wired simultaneously with aptX-LL  -- 32ms - 40ms delay/latency

Second, they play wired simultaneously with aptX -- around 100 ms delay/latency

Last, they play wired simultaneously with SBC (standard Bluetooth) -- around 250 ms delay/latency

This is a GREAT way to actually HEAR the differences -- hearing both speakers being compared simultaneously allows you to really experience exactly what kind of "delay" or "latency" you are dealing with, with each different source (compared to a "wired" connection).

My conclusion -- aptX-LL has NO noticeable delay, aptX has a tiny bit, but I believe it would be nearly, if not totally, insignificant for detecting purposes, and SBC (standard Bluetooth) has significant delay that would make locating targets "visually" (in terms of location of the target in the ground relative to the coil location, based on tone) somewhat difficult/troublesome.

Audibly illuminating demonstration!  Thanks for finding and posting this.

I find it interesting that with the very slight difference in pricing between APTX and APTX LL products that anyone still buys APTX non-LL anymore.

Remember, the perceived delay will depend on the swing speed.  Quite noticeable with regular aptx for me. Gamers think they need LL, and I think detectorists will, too, once they've compared. But try for yourself.

Really interesting thanks for posting the video.
