Speaking of OTTO, does anyone have experience with the NoizeBarrier Range SA headset?

NRR between Sordins and Peltor 500s but if they use the same technology as the NoizeBarrier (ugh, really?) Micro earplugs, perhaps they pair well. The earplugs reviews are near universally positive but I can find few reviews of the headset.
