Sony WH-CH520 Wireless Headphones Bluetooth On-Ear Headset with Microphone and up to 50 Hours Battery Life with Quick Charging, Black Review

At first glance, the Sony WH-CH520 looks like it has no business being this good at its price point. Lightweight, foldable, and sporting a claimed 50-hour battery life, it's the kind of headphone that makes you do a double-take at the price tag. But does it actually deliver? Let's get into it.

Design: Minimalist and Surprisingly Portable

The CH520 goes all-in on simplicity. The on-ear design is slim and foldable, making it easy to toss in a bag. It's plastic all the way through — don't expect the premium feel of Sony's higher-end XM series — but for daily commuting, office use, or casual listening, the lightweight build actually works in its favor. You can wear these for hours without the kind of fatigue that heavier cans cause. The headband doesn't clamp aggressively, though some users with larger heads have noted it can feel a bit loose over time.

Battery Life: The Real Star of the Show

Sony rates the CH520 at up to 50 hours of playback — and in real-world use, that claim holds up surprisingly well. Most users report getting comfortably into the 40-50 hour range under normal listening conditions. Quick charging is a genuine convenience here: just 10 minutes of charge gives you roughly 90 minutes of playback, which is a lifesaver when you forget to plug in overnight.

For context, competing budget headphones in this price range typically offer 20-30 hours. The CH520's battery longevity is a genuine differentiator, not just marketing fluff.

Sound Quality: Good Enough, Not Spectacular

Here's where you need honest expectations. The CH520 delivers a warm, bass-forward sound signature that most casual listeners will find enjoyable — podcasts, pop, hip-hop, and lo-fi all sound perfectly pleasant. The soundstage is narrow, as you'd expect from an on-ear at this price, and audiophiles will immediately miss detail in the mids and highs. But as a daily driver for commutes, work-from-home calls, or gym sessions? It punches above its weight.

The built-in microphone is serviceable for calls and video meetings, though it's nothing you'd want to use for recording. Background noise bleeds through noticeably, so open-plan office workers may want to step away from the desk for calls.

Notably, there is no active noise cancellation. This is a passive isolation only product. If ANC is a priority for you, look elsewhere — the Sony WH-1000XM5 is the obvious step up, at a significant price jump.

Connectivity and App Support

Bluetooth 5.2 keeps the connection stable, and the Sony Headphones Connect app lets you customize the EQ and manage settings. Multipoint connection isn't available here — you can only pair one device at a time, which is a real limitation if you constantly switch between a phone and a laptop. Several users flagged this as a day-to-day annoyance that doesn't show up in the spec sheet.

What's Missing — and Why It Matters

Let's be specific about the trade-offs:

• No ANC. Loud environments (trains, busy offices, flights) will bleed through clearly.
• No multipoint pairing. One device at a time only. A daily frustration for multi-device users.
• On-ear, not over-ear. Extended listening sessions can cause ear fatigue for some users — especially those with glasses.
• All-plastic build. Feels fine initially, but long-term durability reports are mixed. The hinge area is the most commonly cited weak point after heavy use.
• No 3.5mm audio cable included in some regional variants — check your package.

Who Should Buy This?

The CH520 is genuinely excellent for students, remote workers, casual commuters, and anyone who needs reliable all-day Bluetooth headphones without spending serious money. The battery life alone justifies the purchase for most people in this category — you simply won't be reaching for the charger every other day.

If you're a frequent flyer, a hybrid worker who switches between devices constantly, or someone who needs to block out serious background noise, the CH520's missing features will become real frustrations. In that case, budget up to something with ANC and multipoint support.

Frequently Asked Questions

Q: Does the Sony WH-CH520 have active noise cancellation?

A: No — the CH520 offers only passive isolation. It blocks some ambient sound through the ear cup seal, but there is no electronic ANC. If noise cancellation is essential, consider the Sony WH-1000XM5 or similar ANC-equipped alternatives.

Q: How long does the Sony WH-CH520 battery actually last?

A: Sony rates it at up to 50 hours, and real-world use consistently falls in the 40-50 hour range. Quick charging adds about 90 minutes of playback from just 10 minutes of charge via USB-C.

Q: Can the Sony WH-CH520 connect to two devices at once?

A: No. The CH520 does not support multipoint Bluetooth — it pairs with one device at a time. Users who regularly switch between a phone and laptop should be aware this is a notable limitation.

Q: Is the Sony WH-CH520 good for gym use?

A: For light gym use or walks, yes — the lightweight design and long battery make it practical. However, it has no water or sweat resistance rating, so heavy sweat sessions may be a risk over time.

Q: How does the WH-CH520 compare to the WH-CH720N?

A: The CH720N adds active noise cancellation and multipoint pairing at a higher price. If those features matter to you, it's worth the upgrade. For pure battery life and casual listening at a lower cost, the CH520 holds its own.

The Sony WH-CH520 is an easy recommendation for budget-conscious buyers who prioritize battery life and everyday comfort over premium features. It won't impress audiophiles or frequent flyers, but for the price, it's hard to beat. Just go in knowing what you're not getting.
