Thank you for viewing. This is a wireless earphone that you wear over your ears. It's very light and doesn't cause fatigue when worn. It's also unlikely to fall out, making it useful for gardening and travel. This item is sold on Amazon for 3900 yen. I purchased two of the same item, and this one is unused, so I'm putting it up for sale. Although it is unopened, there may be minor scratches on the outer packaging. I am not offering a discount.
