Sony WH-CH520 Wireless On-Ear Headphones with Microphone

Jam out to your favorite music while you wear the Sony WH-CH520 wireless on-ear headphones. While these headphones already support high-quality sound, the Sony | Headphones Connect app allows users to customize the audio levels to their unique preferences with the EQ Custom feature. If you're not sure how best to master your music, try out the range of presets the app offers as well. DSEE™, or Digital Sound Enhancement Engine, is able to fade out distortion and enhance other frequencies to restore each song to its original studio quality. Want to feel like you're experiencing your music live or like you're in the recording booth with your favorite artist? Try 360 Reality Audio, as it makes each beat and rhythm immersive, lifelike and so surreal. Keep enjoying that upgraded sound all day if you want, since the Sony WH-CH520 headphones have a 50-hour battery capacity. In case of emergency, you can even do a quick charge which gains you 90 minutes of playtime in just three minutes. This long battery life makes your wireless headphones the ideal companion for road trips or music festivals.

The Sony WH-CH520 headphones come with extra special features as well. Utilize the buttons on the headphones to pause, play, stop or skip tracks, as well as adjust the volume. Thanks to the built-in microphone, you can take phone calls completely hands-free, no smartphone needed. To extend the hands-free technology even further, try using the built-in mic to speak to a voice assistant like Siri or Google Assistant, as they give you the power to text message, set reminders and more. The Sony WH-CH520 has Bluetooth compatibility that allows users to connect two Bluetooth devices to the headphones at the same time, switching back and forth seamlessly. Never lose your over-ear headphones again, as Google's Fast Pair feature can signal them with a small sound or track their last location using the Find My Device app. The Sony WH-CH520 headphones are lightweight and designed for comfort, with a head cushion, soft earpads and silent joints. The swivel design ability is perfect for the music-loving traveler too, as it makes the headphones more compact for packing.
