Overview
Key Features
The WH-CH520 has a Bluetooth multipoint connection, easy button operation and can even be controlled with your voice. Easy pairing with Swift Pair and Fast Pair, these Sony headphones are ideal for everyday use.
With a battery life of up to 50 hours, you can listen to your favourite music without worrying about the battery. If the battery of your headphones runs low, a 3-minute quick charge gives you 1.5 hours of listening to music.
The Digital Sound Enhancement Engine (DSEE) restores your music with high frequencies and gradually decreasing sound for a more authentic performance. With the EQ settings in the Sony Headphones Connect app, you can even adjust the sound to your own taste and create an individual listening experience.
Take calls with a click of the buttons on the ear cups without having to take your phone out of the case. Thanks to the high-quality built-in microphone and noise cancelling, the WH-CH520 records the sound and reduces ambient noise during the conversation, so you can have clear conversations even in noisy environments.
With the adjustable headband, soft ear pads and lightweight design, you can find the perfect fit for you, so that the on-ear headphones stay comfortable for longer.

Pros & Cons
👍 Pros
- 50-hour rated battery life leads the sub-$100 on-ear category, reducing charge cycles per week to near-zero for most users
- Bluetooth multipoint connection handles two simultaneous device pairings, eliminating manual re-pairing when switching between laptop and phone
- 3-minute quick charge recovery to 1.5 hours of playback provides a practical emergency buffer
- DSEE processing engine reconstructs compressed audio by restoring high-frequency content lost in lossy codecs like MP3 and AAC
- 24-ohm impedance and 20Hz–20kHz frequency response cover the full audible spectrum from a compact, 5.1-ounce chassis
👎 Cons
- On-ear form factor transmits more ambient noise than over-ear designs — the 10-meter Bluetooth range and lack of ANC mean the WH-CH520 does not isolate well in loud environments
- DSEE processing is a digital enhancement, not lossless audio recovery — listeners with critical monitoring needs will notice its limitations on high-resolution source material
- Bluetooth range rated at 10 meters is conservative by current standards; real-world performance through walls or interference-heavy environments can fall short
- Plastic construction keeps weight at 5.1 ounces but limits perceived build quality relative to metal-reinforced competitors at similar price points
- No analog input cable listed in included components — verifying wired fallback capability requires checking the physical port on the unit
Frequently Asked Questions
What does Bluetooth multipoint connection mean on the WH-CH520, and why does it matter?
Multipoint allows the WH-CH520 to maintain active Bluetooth connections to two devices simultaneously — for example, a laptop and a smartphone. Audio switches to whichever device is actively playing, and incoming calls on the phone interrupt laptop audio automatically. There is no need to manually unpair and re-pair when switching contexts.
How accurate is the 50-hour battery claim in real-world use?
The 50-hour figure applies at moderate volume without DSEE processing enabled. Enabling DSEE and using higher volume levels will reduce runtime. Independent testing typically lands in the 40–50 hour range depending on workload — still class-leading for the price tier.
What does the 3-minute quick charge feature actually deliver?
Three minutes on the USB charging cable yields approximately 1.5 hours of playback. This is a genuine emergency feature — it uses a burst charge cycle to recover enough cell capacity for a meeting or commute when the battery runs to zero.
Does the WH-CH520 have active noise cancellation?
The product listing references noise cancelling in the context of the microphone only — the built-in mic uses noise reduction to clean up call audio. Passive isolation from the on-ear earcup design provides some ambient noise attenuation, but this is not an active noise cancelling (ANC) headphone in the playback sense.
What is the impedance spec and does it affect what I can drive the WH-CH520 from?
The WH-CH520 measures 24 ohms impedance. Over Bluetooth this is irrelevant — the DAC and amplifier are built into the headphone. If used in wired mode (if supported), 24 ohms presents an easy load for any standard 3.5mm output.
