The Sony WH-CH520 Wireless Headphones are lightweight on-ear Bluetooth headphones designed for everyday music, calls, work and entertainment. Sony equips them with 30mm drivers and DSEE™ technology, which helps restore detail lost when compressed digital music files are played. With up to 50 hours of music playback, multipoint Bluetooth connectivity and a compact 147 g design, the WH-CH520 is built for users who want long battery life without the bulk of larger over-ear models.

Sony WH-CH520 Wireless Headphones
The WH-CH520 uses 30mm dynamic driver units in a closed on-ear configuration.
Sony combines these drivers with DSEE™, or Digital Sound Enhancement Engine, which processes compressed audio to restore some of the musical detail lost during compression.
The result is intended to provide balanced everyday audio for music, podcasts, movies and voice content.
Sony officially specifies a Bluetooth frequency response of 20Hz to 20,000Hz at 44.1kHz sampling.

Up to 50 Hours Battery Life
Battery endurance is one of the WH-CH520’s strongest features.
Sony rates the headphones for up to 50 hours of music playback under specified conditions.
This can be convenient for commuting, travel, online classes and office use because users may be able to go several days between charges depending on daily listening time.
Sony separately specifies up to 40 hours of continuous communication time and up to 200 hours of standby time.
Actual runtime varies with volume, calling, Bluetooth conditions and feature usage.
3-Minute Quick Charging
When the battery is low, Sony provides a useful quick-charge function.
A 3-minute charge can provide approximately 1.5 hours of listening time according to Sony’s current product page.
A full charge takes approximately 3 hours through USB Type-C.
This makes the headphones practical when users need a short listening session but have forgotten to charge them in advance.
Bluetooth 5.2 Connectivity
Sony officially specifies Bluetooth Specification Version 5.2.
The WH-CH520 supports SBC and AAC Bluetooth audio formats, allowing it to work with a broad range of compatible phones, tablets and computers.
Wireless operation removes the need for a 3.5mm audio cable.
It is important to note that the WH-CH520 has no analogue audio input, meaning it cannot simply be converted into a passive wired headphone if its battery is depleted.
Multipoint Connection
Sony includes Multipoint Connection, allowing the headphones to be paired with two Bluetooth devices simultaneously.
For example, users can remain connected to a laptop for music or meetings while also keeping a smartphone paired for incoming calls.
When a call arrives, the headphones can recognise the appropriate connected device and switch accordingly.
This is particularly useful for users who regularly move between work and personal devices.
Built-In Microphone for Calls
The WH-CH520 incorporates a built-in microphone for hands-free calls and online meetings.
Sony highlights improved call performance and voice pickup as part of the model’s everyday-use feature set.
The microphone allows users to answer calls directly from the headset without holding a phone.
Voice-assistant functionality can also be used with compatible connected smartphones and services.
Sony | Sound Connect App
Users can personalise the WH-CH520 through Sony’s current Sony | Sound Connect application. Sony’s official site highlights custom sound adjustment through its companion app.
The app provides access to EQ adjustment and compatible headphone settings.
Older product descriptions may call it Sony | Headphones Connect, but Sony now uses the Sound Connect branding.
This is worth updating on a current WooCommerce listing to avoid sending customers to an outdated app name.
Lightweight 147 g Design
Sony lists the WH-CH520 at approximately 147 grams, making it a lightweight wireless headphone.
The design includes an adjustable headband, soft ear pads and swivel earcups for comfortable everyday wear.
The on-ear format sits directly over the ears rather than surrounding them completely.
Comfort therefore varies by head and ear shape, and users should take breaks during very long listening sessions.
No Active Noise Cancellation
The WH-CH520 should not be marketed as an active noise-cancelling headphone.
Sony’s official specification confirms no Ambient Sound Mode and the model does not include ANC.
The closed on-ear construction may provide some passive reduction of surrounding sound depending on fit, but it does not electronically cancel environmental noise.
Customers who specifically need ANC can compare other Sony models, including products such as the Sony WF-C700N ANC earbuds at Nikshan Electronics.
