Purchase date: July 2022, purchased on Amazon Owner history: One owner Shipping method: Rakuraku Mercari Delivery Takkyubin Compact (Supplementary information) Rather than powerful sound that makes you want to listen to rock music at high volume, I feel it is more suitable for gentle narration and quiet music that doesn't tire your ears. I bought it thinking it was perfect for remote meetings because it also has a microphone function, but I found that the speakers were more relaxing, so I ended up not using it much and it was sleeping in a drawer. When listing it, I fully charged it and watched action movies on YouTube, pausing in between, until the message to charge appeared, and the total viewing time was 6.9 hours. The catalog value when new is stated as 9 hours, so it's a relatively good number. The earpieces that came with the purchase (S/M/L 3 types, green) are almost unused, so I will include them. (I was using black ones that I purchased separately. I will send them attached to the earphones. The black earpieces in photo 1 are those). A charging adapter and cable are not included, so please prepare them separately. The specifications are 5V voltage and 1A or more current, so a general adapter and USB-C cable used for mobile phones, etc., will be fine.
