Sony WH CH520, Wireless, Calls/Music, 147 g, Headset, Black
WH CH520
Enjoy high sound quality all day long. The WH CH520 headphones with up to 50 hours of battery life, stable connectivity, and enhanced call performance, meet the demands of your day.
A listening experience just for you
Digital Sound Enhancement Engine (DSEE) restores the harmonics and liveliness lost during typical music compression, for a more authentic performance. You can even tailor music to your own taste with EQ settings on the Sony Headphones Connect app, for a personalised listening experience.
Stay powered up for days
With up to 50 hours of battery life, you can listen to your favourite music without worrying about running out of charge. And, if your headphones battery is running low, a three minute quick charge can give you 1.5 hours of listening time.
Crystal clear calls
A built in microphone provides you with hands free calling, and it also works just as well for joining an online class or work meeting.
Multipoint connectivity
For total convenience, these Bluetooth headphones can be paired with two Bluetooth devices at the same time. So when a call comes in, your headphones know which device is ringing and connects to the right one automatically.
Designed for all day comfort
Not only is the design stylish, but it's also crafted with ease of use in mind. The lightweight build and swivel earcups gently slip on and off, while the adjustable headband, cushion and soft ear pads give you all day comfort.

| Ear coupling Ear coupling describes the way in which headphones or earphones stay attached to, or inside, the ear. There are three common types of ear coupling: circumaural, supra-aural and intra-aural. Circumaural headphones enclose your ears with large pads that suppress external noise. Supra-aural headphones are typically more lightweight and sit on top of the ears with small pads. Intra-aural headphones come in two basic designs and neither style sits on the head itself. The first are ear buds, which sit just outside of the ear canal, on top of your ear lobes. The second type is actually inserted directly into the ear canal and offers some external noise suppression. | Circumaural |
