So I was a lucky winner of a free pair of these guys because I had the SW4’s which I absolutely love. These are even better because two different devices can be connected to it. Either Bluetooth or using the dongle. I have 2 negatives, 1 is the manual is really small and I have pretty poor eyesight so maybe a PDF version that I can zoom in and out of? 2 the case is a bit hard to open, at least for me.
