Wireless headphones with 35-hour battery life and noise-canceling function. - Brand: SONY - Model Name: WH-CH720N - Color: Blue - Noise Canceling: Yes - Battery Life: 35 hours - Accessories: Cable, Cover Thank you for viewing. Purchased around December of last year. Used for commuting for about 2 months. The headphones didn't suit me, so I haven't used them for several months. The charging cable is a spare cable, and it's unclear if it's the original cable. (Type-C cable) The cover was purchased additionally on Amazon. It's made of silicone and has a smooth surface. Since it's used, please refrain from purchasing if you are concerned about dust or dirt. (Basically, returns are not accepted.)
