Sony WH-CH520 Wireless On-Ear Headphones (Blue)

Usage Instruction

• Power On & Pairing: Slide and hold the power switch to the "ON" position until the indicator light flashes blue. On your Bluetooth device (phone, tablet, PC), go to Bluetooth settings, select "WH-CH520" from the list, and pair. A voice prompt will confirm a successful connection.

• Wearing & Adjusting: Place the headphones over your ears and gently extend the headband for a comfortable, secure fit. The cushioned earpads should rest lightly on your ears.

• Basic Controls: Use the buttons on the right earcup to manage your audio: press the multi-function button to play/pause or answer/end calls (press twice to redial); use the volume +/- buttons to adjust sound; press and hold the multi-function button to activate your device's voice assistant (e.g., Siri, Google Assistant).

• Charging: Use the included USB-C cable to connect the headphones to a power source. The indicator light turns red while charging and turns off when charging is complete.

• Power Off: Slide the power switch to the "OFF" position after use to conserve battery.

Safety Warning

• Volume & Hearing Safety: Avoid listening at high volume levels for extended periods, as this can cause permanent hearing damage. Be especially cautious in noisy environments where you may be tempted to increase the volume excessively.

• Situational Awareness: Do not use these headphones in situations where full awareness of your surroundings is critical for safety, such as while cycling, driving, or walking near traffic. Keep volume at a low level or use only one earcup if you must be aware of ambient sounds.

• Battery & Charging: Use only the provided or a certified USB-C cable and a standard 5V charger. Do not charge the headphones near flammable materials. If the battery, headphones, or cable are damaged, stop using and charging them immediately.

• Cleaning & Maintenance: Clean with a dry, soft cloth. Do not use liquids or chemical cleaners. Keep the headphones away from extreme heat, moisture, and direct sunlight.
