Sized up for socks but didn?t need it. My Astro A40 TR came well packaged and undamaged. I purchased these for my 6th grader to use for school, they fit his ears very well. But it seems to have made some seriously abused Birks look better/shinier, and possibly rebonded some broken cork, so yeah, is good. I tried to think of the right word to describe it and came up with "obnoxious". The break in quickly and comfortably ! Im very happy with its look and function and am ordering another for the bottom door and one for the inside wall. I put it on, fit great (after reading sizing recommendations) it did exactly what I wanted for smoothing in all the places I needed. Which also brings me to adding that these buds stay in during all my various intensity workouts. I own a good pair of Samson headphones and the PeohZarr headset sounds nearly identical.
