within 5 min of ordering the same size shoe said 50. They are so comfortable and light, that you hardly know you are wearing them. Well, I guess as excited as one can be about deodorant. *However* the treble is uncluttered and clear, unlike most every other IEM in this price category. I have to use the Bluetooth, which I didn?t want to. In most Windows programs this isn?t an issue, but when playing games, it can cause some unfortunate side effects. I first tried a $55 shotgun. The old was easily removed by pulling out and the new one snapped firmly into place quite easily. They are light and dont protrude too far. I also felt like I had enough arch support to stand in them all day.
