THIS ONE IS BEAUTIFUL, EFFECTIVE AND WORTH IT (so far)! It gets louder at higher settings (1 being the easiest). If you have wide feet, do not buy these shoes. It will work fine, until it gets pulled on a touch too hard by one of my kids and then it will break, I’m sure. I sure do! I got these spicifically because it was titled for kids. Hope it gets fitter after this period. Its too tight. So far so good, will update if any issues. i want to preface this by saying i really wish i could give these earbuds a higher rating; i think the sound quality is great for the price and i enjoy the fact that its very balanced (not too much bass, treble or mids, it all sounds great imo).
