I think the volume is higher than the mpa. If I got this I would’ve used it for my earbuds, lip balm, iPhone cable, spare hand sanitizer and maybe one of those tiny sewing kits for emergencies. I remember I used to have a bag this size back in the day and it was the best because I could fit all my wallet things in AND my phone! When phones used to be tiny… a razr would fit perfectly in this I think LOLI have the wapity being shipped to me. I still can't think of a use for it! My SA says it can be used to be carry cards but I have cardholders. I might return it if I can get the glasses case.
