Please confirm the details until the end. Purchased on August 9, 2025. *Because this item is also listed elsewhere, it will be sold on a first-come, first-served basis. Recently purchased junk item. For those who can repair it, or those who only want one side, it's a hassle to return it. The battery life of the right side in the image is poor, and it turns off in about 5 minutes. Check the image. The red circle indicates the junk item. The left earphone works normally. *This is the first time I've used this type of earphone, so I'm not sure which is left and right. *I bought two, and one was a junk item. *The sound is very good, and you can turn off the power, pause, and make phone calls by touching either the left or right earphone. However, it may take some getting used to. *Convenient features included. It automatically connects to your smartphone when removed from the case and charges when stored. Very easy to use. *Color: Black and Yellow, cool! *Please check the images for details. *Manual images are attached.
