They were adequate, but really not sturdy enough for stacking. I decided to get the freebuds 3 because it seemed like the perfect middle ground of the airpod pros and the regular ones, an open fit design for comfort and with active noise cancellation. Love this wall mount. Same goes for the foam ear tips and I tried different sizes. It is flimsy. The problem with this is that if one of these ever gets loose, it can fall all the way down and out of the mount. S sandals so I felt confident about their sizing. But the PCB traces are not as thick/wide as I would like to see, just guessing they are equivalent to #20 wire. The 6 was a perfect fit. I use it as a slipper around the house.
