The variety of sizes allows me to use it for different purposes. These were delivered today, I purchased them as a gift . I did so based on other reviews. Bought three different colors of these shoes. I am frankly amazed at how much clear sound this little softball sized speaker can deliver. The color is pretty, it came with the photocards, stickers, headphones, and a case in the box! Sennheiser, a great in audio reproduction, can do better that this, even for cheap phones. 🤠👍 When it comes to other swinging activities I prefer to go lighter and this makes it really easy to do so. Para personas con pies mas anchos les viene muy bien, pero si recomiendo que lo ordenen un número mas chico al habitual.
