Pink Cat Ear Headset (for Kids)

I'm an online tutor, and I bought a pink cat-ear headset thinking it would motivate me when teaching English to a young elementary school girl. However, after testing it with English audio, I realized the bass was too heavy and it wasn't suitable for English learning, so I ended up not using it. Therefore, I only wore it once or twice. As you can see in the picture, it's practically brand new. Would it be suitable as a supplementary device for your child's tablet, etc.? Please understand that the shipping cost will be 750 yen due to the size. impeccable for everyday use. finest materials and excellent craftsmanship ensure long-lasting durability.
