High-quality wireless earphones with Bluetooth 5.3 and up to 60 hours of playback. Received from Amazon on 2023/11/13, and while there are no defects, I no longer have a need for these as the earphones I was previously using have been restocked. Used approximately 5 times. Ear tips are not included. Please use your own ear tips. Please refer to the 8th photo for specifications. These are inexpensive, so they may not be suitable for those seeking high sound quality. They were sufficient for watching videos. Originally priced around 2700 yen, but the black color seems to be out of stock currently. - Brand: Ethernote - Bluetooth Version: 5.3 - Battery Capacity: 500mAh - Playback Time: Up to 60 hours - Charging Method: Type-C - Waterproof Rating: IPX7 - Driver Size: 16mm - Main Unit Usage Time: 4 hours
