The Sony WH-CH520 headphones are engineered for daily versatility, offering a blend of sound quality, convenience, and comfort. Here's how they perform in real-world scenarios:
Seamless Multitasking: Imagine you're enjoying a podcast on your laptop while working. If your phone rings, the Multi-Point Connection automatically pauses the podcast and switches the audio to your phone, allowing you to answer the call. Once done, it seamlessly reverts to your laptop's audio, eliminating the need to manually reconnect devices.
Music on the Go: For commuters or travelers, the 50-hour battery life means you can go days, even weeks, without needing a recharge. If you're in a hurry, a quick 3-minute charge before you leave the house provides 1.5 hours of playback, perfect for a short trip or a quick workout.
Enhanced Listening Experience: When streaming your favorite music, the DSEE (Digital Sound Enhancement Engine) actively works to restore the nuances often lost in compressed audio files. This results in clearer vocals, richer bass, and more distinct instrument separation, making your daily soundtrack sound more vibrant and engaging.
Crystal-Clear Conference Calls: Whether you're in a bustling office or a busy coffee shop, the built-in microphone with noise suppression technology ensures your voice is picked up clearly by the person on the other end, filtering out distracting background sounds. This makes the WH-CH520 ideal for professional calls and virtual meetings.
Charge Fully: Before first use, connect the headphones to a USB power source using the provided USB-C cable. The charging indicator will turn off once fully charged.
Enter Pairing Mode: With the headphones turned off, press and hold the power button for approximately 7 seconds. The indicator light will flash blue rapidly, signaling that the headphones are in Bluetooth pairing mode.
Connect to Device: On your smartphone, tablet, or computer, navigate to the Bluetooth settings. Select "WH-CH520" from the list of available devices to complete the pairing.
Multi-Point Connection (Optional): To use Multi-Point with two devices, first pair with device A. Then, turn off Bluetooth on device A. Put the headphones back into pairing mode and pair with device B. Finally, re-enable Bluetooth on device A. Both devices should now be connected to the headphones.
Bluetooth Devices: Compatible with any audio source that supports standard Bluetooth profiles (e.g., smartphones, tablets, laptops, smart TVs).
Voice Assistants: Fully integrated with Google Assistant and Siri on compatible mobile devices via the dedicated button.
Cleaning: Regularly wipe the earcups and headband with a soft, dry cloth. For light stains, a slightly damp cloth can be used. Avoid abrasive cleaners or solvents.
Storage: When not in use, store the headphones in a cool, dry place. The swivel earcups allow them to be folded flat for compact storage, protecting them during travel.
Charging Habits: Use a reliable USB-C charger. Avoid completely depleting the battery for extended periods to maintain optimal battery health and longevity.
Environmental Protection: Do not expose the headphones to excessive moisture, rain, or extreme temperatures, as they are not designed to be water-resistant.
