Sony WH-CH520

The Sony WH-CH520 packs a 50 hour battery and 90th percentile connectivity into a 60 gram frame. The sound is dead average at the 49th percentile, and the build quality is a weak 35th percentile. It's a battery champ for multi-device users, not an audio upgrade.

Let's talk about what these do well first. The 50 hour battery is the headline number, and it's a real one. That's 87th percentile territory, meaning most headphones in our database can't touch it. The quick charge is also solid: 3 minutes of charging gets you up to 90 minutes of playback. That's the kind of feature you actually use when you're running out the door and realize you forgot to plug them in overnight.

Connectivity is the other bright spot. Bluetooth 5.2 with multipoint support means you can stay connected to your laptop and your phone at the same time, and the 90th percentile ranking backs that up. The 60 gram weight makes these easy to forget you're wearing, and the foldable design means they'll actually fit in a bag without taking up half of it. The dynamic driver handles Hi-Res audio on paper, but the 49th percentile sound score tells you the tuning isn't going to blow anyone away. It's fine, it's just not special.

Against the JBL Tune 670NC, the Sony wins on battery life but gives up ANC performance. The JBL is a more balanced package if noise canceling matters to you. The Sennheiser MOMENTUM 4 is in a completely different league on sound quality, but it also costs several times more and weighs significantly more than 60 grams. The TOZO HT3 is the budget wildcard here, often undercutting the Sony on price while offering surprisingly decent ANC for the money. The Beyerdynamic Aventho 1001609 is the audiophile pick with far better build quality, but you'll pay for it. The Skullcandy Aviator S6AVW-T740 is the closest direct competitor in terms of positioning, and it's a coin flip on sound. If battery life and multipoint connectivity are your top priorities, the Sony holds its own. If you care about audio quality or build, most of these competitors pull ahead.

Pricing on these is a bit of a moving target. The US listings we track range from USD 60 to USD 68, a spread of USD 8 depending on which store_name you're looking at. The bundle with the stand is the pricier option at the top of that range, while the standard bundle comes in at the lower end. For a headphone with 50 hours of battery and top-tier connectivity, USD 60 feels reasonable. At USD 68, you're paying extra for a stand that doesn't change what the headphones actually do. Shop around a little and grab the cheaper listing if you can.

The Sony WH-CH520 lands in our database with a total score of 55.6 out of 100, which is about what you'd expect from a budget on-ear pair. The story here isn't raw audio quality, it's the battery and connectivity. A 50 hour battery life sits in the 87th percentile, and the Bluetooth 5.2 with multipoint support ranks in the 90th percentile for connectivity. That's genuinely impressive for a headphone that weighs just 60 grams.

But the sound tells a different story. At the 49th percentile, the audio is dead average, and the mic is right there with it at the 46th percentile. The build quality is a weak spot at the 35th percentile, and the ANC ranking of 32nd percentile is rough, though to be fair, these don't really market themselves as noise canceling champs. If you want a lightweight pair that lasts forever on a charge and pairs with everything, this is interesting. If you want studio sound, the 36.9 out of 100 studio score should steer you away.

Skip these if you care about sound quality or build. The 49th percentile sound score means you're getting average audio at best, and the 35th percentile build quality suggests these won't survive years of daily abuse. The 32nd percentile ANC performance is also a letdown if you were hoping for any meaningful noise isolation. And if you're doing any kind of studio work, the 36.9 out of 100 studio score is a clear signal to look elsewhere. The mic at the 46th percentile is fine for quick calls but not great for long meetings or recording.

The WH-CH520 is a battery and connectivity specialist wearing a budget headphone costume. The 50 hour battery and 90th percentile connectivity are genuinely great, and the 60 gram weight makes them comfortable for all-day wear. But the 49th percentile sound and 35th percentile build quality mean you're making real trade-offs. At USD 60, this is a solid buy for commuters and multi-device users who prioritize battery over everything else. At USD 68 with the stand bundle, the value proposition gets shakier. If sound quality is anywhere near the top of your list, look elsewhere.
