I bought these lightweight, high-quality headphones half a year ago, without hesitation. However, I felt they were too precious to use, and they've been sitting unused ever since, so I'm putting them up for sale. All accessories are included. They are in excellent condition with no wear, tears, or cracks. There are no odors or stains. Battery life is as stated in the catalog. With normal use, they last about 2.5 to 3 days. If left unused, they seem to last about a month. There's an app for your smartphone that allows you to control them extensively. However, the more you customize them, the faster the battery drains and the more quickly they wear out. I mostly used them on the default settings and turned them off when I wasn't using them. I hate to say it myself, but they are in beautiful condition. Thank you for your interest. High-quality wireless headphones with noise-canceling function. - Model Name: WH-1000XM4 - Brand: SONY - Included Accessories: Charging cable, audio cable - Color: Black Thank you for looking.
