Sony WH-CH730N Wireless Over-ear Headphones, Black

The Sony wireless noise-cancelling headphones in black provide over-ear listening with active noise cancellation. This reduces background noise when playing music, podcasts, or other audio. Bluetooth enables a wireless connection for playback and hands-free calls. Battery life is rated at up to 50 hours with noise cancellation enabled, and switching it off extends the stated maximum playback time to 75 hours, giving longer listening between charges when noise reduction isn't needed.

The closed-back earcups are mounted on a headband, and the headphones weigh 207 g. A folding design allows them to pack down for storage or travel. A detachable 1.2 m cable is included and connects via a 3.5 mm socket for wired listening. Built-in microphones handle voice calls, so no separate microphone attachment is needed. On-device buttons control playback and volume, including answering and ending calls. A full battery recharge takes approximately three hours.
