The Middling:- Liftoff distance seems higher than the 3366, but still seems to be under 1. The only problem was that sometimes the top wouldnt work properly, but I could work through that just fine and it didnt change the way I felt about the product overall. Fits the charging cable right inside nicely. * When driving my lawn mower, I do not think there is much difference between Noise Cancellation mode and off mode. I probably didn?t choose the right pattern. There?s sticker you have to peel off before using maybe to protect it from scratches. The padding on the top of the head makes it really comfortable. I think everyone will enjoy anything from here. Warm and cozy, but they dont make my feet sweat. For the price of this tuner, SCT should provide more customization on the pre-loaded tunes and/or provide custom tunes directly.
