These are Sony WF-1000XM4 earbuds. I've used them for about 2-3 years, and they likely no longer function properly due to battery degradation. I haven't touched them in about six months, but I remember they only lasted about 10 minutes. I haven't confirmed their operation. They might be usable for someone who can replace the battery themselves. I'm looking for the accessories, as I don't think I threw them away. I will add images and include them if I find them. - Brand: SONY - Type: Wireless Earphones - Included: Charging case Thank you for looking.
