I have a nice low use pair of these ready to ship. I've used them for a few years - 2014 models at very low speed most of the time. They are quiet and have the upgraded QD wetsides. I'll also include an original wetside that works as well as the QDs and can be rotated for cleaning if you buy the pair. These are the wireless versions that worked extremely well with my Apex. $200 each or both with extra wetside for $375. Shipping included - continental US only.
