If you dont need A2DP, I would give them 3. I considered returning them, but I really liked them aside from the adjustment and took them to my local shoe repair shop & they adjusted the straps for $10. and it feels sort of sketch. I have this paired up with a 39W QC3. Very useful in adding a round Yakima bar to the Timberline mounts. Which I didnt think about until I tried to return them. So dont buy this if that is what you like about it. Much better than the cheap plastic ones (that are really not that cheap)! I like my wireless charger! I wear them for casual wear, morning walks, and playing golf.
