hi, recently got my 1st detector the nox 600, and still getting to grips with my new toy and hobby, i am having trouble with getting multiple sets of wireless headphones to show the + for the low latency, even though they are models that other users seem to have no trouble with i have now tried multiple ear buds, and just bought a set of August EP650 which are supposedly aptx-ll, I bought these after reading many threads online, and watching a few videos and the EP650 seemed a popular and financially great buy and all ive seen and read do indeed show this model headphone connected to the equinox range and have the +, so bought them i did, they pair perfectly fine as expected, but do not give the + symbol at all ,tried factory preset/default upon starting up the nox, but same outcome, i probably now have spent on multiple earbuds and headphones more than i would have to get the minelab wireless module ect haha, anyhow could someone possibly shed some light on possible reasons the EP650 just dont wanna play nice on my machine, my nox does have most upto date firmware, but unsure that could cause any issues, but as im new to this, im thinking all possible scenarios , im starting to go a little insane over it
