Sony WH-CH520 Review: Battery, Pairing, Sound Leakage

There’s a specific kind of freedom that comes with budget-friendly headphones you don’t stress about tossing in a bag or wearing all day, but picking the right pair can feel like a gamble. The Sony WH-CH520 offers a colossal battery life and a light fit, and this review digs into whether its 50-hour claim and comfort hold up in real use.

Key Facts About the Sony WH-CH520

The specs read like a checklist for a perfect budget headphone, but the real story is in the nuance of everyday use.

Why are people no longer using wireless headphones?

The question seems counterintuitive on its face, given the sheer volume of wireless products on the market. Yet, the chatter around “quitting” wireless isn’t about abandoning the technology; it’s about being selective. Many users are tired of the constant battery anxiety—the nagging fear that your headphones will die mid-commute. The Sony UK product page highlights the WH-CH520’s long battery life as a primary feature, directly tackling this concern. Another significant shift is the growing awareness of audio quality. As RTINGS notes in their review, features like active noise cancellation (ANC) are often expected, but when they’re missing, as they are on the WH-CH520, users have to consciously decide if they care. The pivot isn’t away from wireless, but towards sets that solve the right problems—like the 50-hour playback that makes charging almost a non-issue.

The shift in buyer preference is a move toward specialization. Rather than buying a jack-of-all-trades, users are increasingly buying the device that does the most important thing perfectly. For these Sony headphones, that’s endurance and comfort.

Is the Sony CH520 worth buying?

The Sony WH-CH520 reframes what to expect from budget headphones: not a watered-down version of a premium feature set, but an expert‑length battery life that outlasts models three times the price. The decision to buy them is a decision to say yes to endurance and lightness, and to say no to noise‑canceling technology and auto‑pause. As you weigh them, consider not what you’re missing, but whether the 50‑hour claim — which dominates the conversation — solves the biggest problem you have with your current headphones. It’s not a one‑size‑fits‑all solution, but for the right user, it’s the only one that matters.

What are the pros and cons?

Every headphone is a compromise. Here’s the breakdown of the Sony WH-CH520’s trade-offs.

The lack of auto-pause is a notable miss. It’s a small feature that has become standard on many competitors, and its absence requires the user to be more disciplined about powering off the device. This small omission, coupled with no ANC, makes it clear that Sony was laser-focused on maximizing battery value and keeping the cost down, sometimes at the expense of modern conveniences.

How does it compare to other budget headphones?

Where the WH-CH520 wins is the battery. Per SoundGuys testing, it outlasts most of its peers, who often land in the 20-35 hour range. While competitors might offer similar sound quality, the endurance of the CH520 is its superpower. In this comparison, the CH520 is the choice for the frequent traveler or the person who forgets to charge their gear. The rest of the market asks you to remember; the WH-CH520 lets you forget.

What is the price and value?

Priced as an entry-level offering, the WH-CH520 sits comfortably in budget territory. The value proposition is simple: more battery for less money.

But value isn’t just price. It’s what you get for that price. With the WH-CH520, you’re forgoing ANC and premium features like auto-pause. However, many users in reviews on sites like TechRadar note that for the price, the sound and features list is hard to beat. It’s not a “flagship killer,” but it doesn’t need to be. It’s a solid, dependable workhorse.

Is the Sony CH520 noise cancelling?

No, the Sony WH-CH520 does not have active noise cancellation. It relies on passive isolation from the on-ear design. The on-ear pads create a physical seal that blocks some ambient sound, but it is not as effective as active noise cancellation. This trade-off is intentional: by omitting ANC, Sony keeps the price low and maximizes battery life. For users who need to stay aware of their surroundings, this can be a benefit.

According to a review from What Hi-Fi?, the audio profile is tuned for a fun, energetic sound that suits pop and rock, which is typical for this price category. The lack of ANC means you’ll hear traffic and announcements, which can be a safety advantage when running errands.

Do Sony WH-CH520 leak sound?

Sound leakage is a common concern with on-ear designs. Because they rest on the ear rather than around it, they don’t create a perfect seal, which allows sound to escape. Here is how the WH-CH520 typically compares.

Comparing sound leakage with other on-ear headphones

Analysis from SoundGuys, a recognized audio equipment testing outlet, emphasizes that while the WH-CH520 doesn’t have the best isolation, its passive isolation is sufficient for most casual listening environments.

How to reduce sound leakage

While you can’t eliminate sound leakage entirely on an on-ear headphone, you can manage it.

• Lower the volume: This is the most effective method. At moderate volumes, leakage is minimal.
• Adjust the headband: Ensure a snug but comfortable fit. A tighter seal against the ears will reduce the sound escaping.
• Consider ear pad material: While not a feature here, in general, pleather pads often create a better seal for isolation.

These steps help but won’t perform miracles. If your primary use case is listening in a quiet office or while commuting, you’ll likely need to be more mindful of your volume, or consider in-ear options which provide a better natural seal.

Does sound leakage affect listening experience?

For most, sound leakage isn’t a deal-breaker—it’s just physics. On the flip side, the lack of ANC and the resulting passive isolation can actually be a boon for safety. You’re more likely to hear traffic, announcements, or a colleague calling your name. The experience is less about being isolated in your own world and more about layering sound over the real world. The question isn’t if it’s a silent experience—it isn’t—but if the music you love sounds good while you’re sharing a bit of it with the room.

How do I connect my Sony WH-CH520 wireless headphones?

Pairing the WH-CH520 is straightforward. Follow these steps:

1. Ensure the headphones are charged (press the power button briefly; an LED should light up).
2. Press and hold the power button for about 5 seconds until the LED starts flashing blue and red — this indicates pairing mode.
3. On your device (smartphone, tablet, computer), open the Bluetooth settings and turn on Bluetooth.
4. Look for “Sony WH-CH520” in the list of available devices and select it.
5. Wait for the connection confirmation. The LED will stop flashing when paired.

If the connection fails, try turning the headphones off and on again, or reset the Bluetooth on your device. The WH-CH520 supports Android Fast Pair, so Android devices will automatically prompt pairing.

What is the lifespan of Sony headphones?

While Sony does not specify an official lifespan, the WH-CH520’s 50‑hour battery per charge is rated for long use. Over time, lithium‑ion batteries naturally degrade, leading to shorter playback between charges. Based on typical battery health decline, you can expect the headphones to maintain good performance for 2‑3 years of regular use. Build quality is solid — the lightweight plastic construction holds up well under daily handling. Sony offers a 1‑year limited warranty. For longer lifespan, avoid extreme temperatures and store the headphones in a cool, dry place.

Summary

The Sony WH-CH520 reframes what to expect from budget headphones: not a watered-down version of a premium feature set, but an expert‑length battery life that outlasts models three times the price. The decision to buy them is a decision to say yes to endurance and lightness, and to say no to noise‑canceling technology and auto‑pause. As you weigh them, consider not what you’re missing, but whether the 50‑hour claim — which dominates the conversation — solves the biggest problem you have with your current headphones. It’s not a one‑size‑fits‑all solution, but for the right user, it’s the only one that matters.
