Speaking of iOS, I'm disappointed that Apple hasn't added additional steps to the volume control for the stock Music player. Twice as many steps would be perfect. I can't tell you how many times I've been annoyed by the fact that when I go up one notch in volume, it's too loud, but when I go down a notch, it's too quiet. Sure, it's theoretically possible to fine tune by moving the volume slider manually with my finger, but it's very difficult to do, at least for me. As soon as I let go, another part of my finger touches somewhere else and it jumps to the wrong position.
There is a way around this, but its janky. Basically set the volume limit on the player at the loudest volume that you would want for any one of your headphones / earphones. For instance, if you set it at half maximum volume, this will give you twice as many additional steps within that volume range.
Same glasses! But there is one or two videos where I am wearing a different pair because I had to get new lenses. (Which are now already scratched grr).
