Thank you all for the replies.
Against all odds, I went ahead and purchased about 6 or 8 bluetooth transmitters & receivers from Amazon hoping to find a combination that would transmit with minimal delay using the AptX "low latency" profile... I tested each/every combination yielding wildly different results (all items had Aptx profile capability).
I FOUND A COMBINATION THAT WORKS!

The transmitter is plugged into the "headphone out" of the Helix. Then I have a standard pair of wired headphones plugged into the receiver. I had to use a 3.5mm to 1/4" adapter to allow the transmitter to plug into the Helix.
There is still a very slight delay, but not enough to throw me off. I put my wired earbuds in, then put a generic pair of sound reducing cans over my ears when practicing w/ my band in the loud lollipop basement.
Given the nature of Bluetooth, it's possible that YMMV but I'm tellin you guys.... I LOVE IT!
