The Sony WH-CH520 is a lightweight, wireless on-ear headphone aimed at everyday listeners who want long battery life, flexible Bluetooth connectivity and a familiar brand without paying for premium noise cancellation. Its headline attractions include up to 50 hours of music playback, multipoint pairing and customisable sound. This is a specifications-based buying guide, not a claim of hands-on testing.
Comfort and design
The WH-CH520 uses an on-ear design: its cushioned pads rest on the ears rather than enclosing them completely. Swivelling earcups and an adjustable headband help it fit into a bag. The design is compact for students, commuters and office users, although on-ear pressure can become noticeable during long listening sessions. Comfort depends on head size and personal preference.
Sound quality and DSEE
Sony includes its Digital Sound Enhancement Engine (DSEE), which is designed to restore some high-frequency information lost in compressed music. Users can adjust equaliser settings in the Sony Sound Connect app. That flexibility is useful because listeners who prefer stronger bass, clearer vocals or a flatter sound signature have different tastes. DSEE cannot magically recreate every detail lost during compression.
Battery life and quick charging
Sony advertises up to 50 hours of music playback, with its support documentation specifying up to 50 hours using the AAC codec and up to 45 hours with SBC under test conditions. Activating features such as equalisation or DSEE may shorten battery life. A three-minute quick charge is rated to provide approximately 1.5 hours of playback. USB-C charging makes the headset practical for regular travel.
Bluetooth multipoint
Multipoint connectivity allows the headphones to remain paired with two Bluetooth devices at the same time. That is useful for someone who listens to audio on a laptop but needs to answer calls on a phone. Switching behaviour can depend on the devices and apps in use, so buyers should not assume every audio stream can play simultaneously.
Calls and controls
A built-in microphone supports hands-free calling and online meetings. Physical controls handle common playback and call functions. As with other wireless headsets, call quality depends on surrounding noise and the microphone’s position. The WH-CH520 is not sold as a headset with active noise cancellation, and buyers should not confuse ordinary passive isolation with ANC.
Connectivity and limitations
The WH-CH520 is a Bluetooth-focused headphone and does not offer a standard analogue 3.5 mm wired listening mode. It is therefore worth checking compatibility with older audio players, airline entertainment systems and desktop computers without Bluetooth. Its on-ear construction also provides less physical isolation than many over-ear models.
India price and availability
Sony India lists the WH-CH520 with an MRP of ₹5,990. Indian authorised retail and marketplace offers have recently been lower, with prices varying by colour and seller. A recent retailer listing showed ₹4,490, while marketplace tracking indicated offers around ₹2,989. These are reference points rather than guaranteed checkout prices. Confirm current stock, warranty, colour and the final amount before ordering.
Who should buy it?
The WH-CH520 is well suited to students, casual music listeners and professionals who want a compact wireless headset for music, videos and calls. Long claimed battery life and multipoint pairing are useful everyday features. If active noise cancellation, a wired audio jack or a fully over-ear fit is essential, consider a different model.
Verdict
Sony WH-CH520 offers a sensible combination of long battery endurance, customisable audio and two-device Bluetooth connectivity. Its compromises are equally clear: no ANC, no analogue wired mode and an on-ear fit that may not suit everyone. Compare live Indian prices and purchase from a seller offering a valid invoice and warranty.
