SONY wireless headphones (noise-canceling). These are new and unopened, stored since purchase. Please refrain from purchasing if you are sensitive, as I have a dog. Shipping is planned via Eco-Mercari (may be subject to change, please understand). I've listed the shipping time as 4-7 days, but I generally aim to ship within 2-3 days. However, depending on the day of the week you purchase, it may take 4-7 days, so I've listed it as such just in case. - Model Name: WH-CH720N - Brand: SONY - Noise Canceling: Supported - Battery Life: 35 hours - 360 Reality Audio: Supported - Equalizer: Equipped - Bluetooth Version: 5.0 - Microphone: Built-in
