I bought this at a home center about a month ago for 1880 yen. I thought I'd be able to listen to it normally, but it turned out to be the type that requires headphones to work. I used it a couple of times, but I'm not used to headphones and they felt uncomfortable in my ears, so I put it away and haven't used it since. Please refer to the ninth photo for the detailed size. It's about the size of a lighter, so it's easy to carry in your pocket and very convenient. This time, I'm including a pair of headphones and two AAA batteries, which I bought at a 100-yen shop. The headphones are TV headphones, for one ear. You can listen to it normally with these. Please refrain from purchasing if you are a perfectionist or overly concerned about minor details.
