I agree with vferrari here. I am not convinced that people are percieving "delay" with aptX-LL, as compared to Wi-Stream. YES, the numbers show that Wi-Stream is faster, but as vferrari notes, there's a limit as to what the human ear can perceive.
I am attaching a video, which I found interesting. It shows, audibly and visually, the "lag" associated different types of wireless feeds. In the first test, using aptX-LL, it's essentially imperceptible, as compared to a wired connection. Both feeds -- wired, and aptX-LL, are played simultaneously, and there is no "echo" perceptible (echo would, of course, would reveal perceptible "lag").
Then, when you see the second test in the video, where
regular aptX and wired are played simultaneously, you definitely perceive the noticeable "lag" -- i.e. the "echo" between the two feeds. But, that echo is NOT there, with the aptX-LL. This supports what I've believed from my study of the issue, and is exactly what vferrari notes, as well. See for yourself...

I would tend to think that it's actually audio CLARITY or QUALITY that makes the difference, when plugging in better headphones into the WM-08, vs. the Minelab (BT-80) wireless phones, as opposed to "lag" being the issue. I also suspect that some of the Minelab Bluetooth headphones sound better than others. I have two pair, and one is very clear and sounds great; the other, not so much. The "not so good" pair sound slightly muffled, and at times there's even a bit of "offset" between what you are hearing in one ear cup, vs. the other.
Another story...when I first got my Explorer years ago, I was using the supplied Koss UR-30 headphones, and thought they sounded just fine (I didn't know any better, as I had nothing to compare them to). But, at the insistence of many, I upgraded -- to a set of SunRay Pro Golds. Let me tell you, there was a HUGE difference. MUCH clearer, MUCH better definition to the different tones, with the Pro Golds, vs. the Koss phones. Bottom line, headphones MATTER.
I will say that my "good" set of Minelab (BT-80) headphones sound "good," while the "bad" set definitely sounds much worse. However, due to this discussion, I am going to do something I haven't done yet -- I'm going to hunt for awhile using my SunRay Pro Gold phones with the WM-08 module. I've been meaning to do this, anyway, for quite awhile, but this thread has motivated me to do so. I am curious to see if my "good" pair of BT-80 aptX-LL phones actually sound "not so good," if compared to the SunRays…
