We would choose the WH-CH530 if LC3 and its advertised battery life matter to you. The WH-CH520 remains an alternative if it costs less and SBC or AAC meets your needs. Weight differs only slightly. This comparison combines Sony documentation and two independent reviews; it is documentary research without hands-on testing or a verified sale price.

Connectivity: check your device first
Sony specifies Bluetooth 6.0 and SBC, AAC and LC3 for the 530; the 520 manual lists Bluetooth 5.2 with SBC and AAC. That is a compatibility difference, not proof of better stability or sound on your phone. Before paying extra for LC3, confirm that your device and its settings support using it.

Calls: reviewers disagree
Expert Reviews reports effective background-noise filtering in WH-CH530 calls. Gizmodo instead found that surrounding conversation came through. These are third-party experiences under different conditions, not evidence of a demonstrated improvement over the 520. If meetings are your main use, listen to comparable microphone samples and check the seller’s returns policy.

Weight, battery and practical limitations
Sony lists approximately 150 g for the 530 and 147 g for the 520. Those 3 g do not predict comfort. The 530’s advertised 55 hours and the 520’s 50-hour claim reported by Expert Reviews are stated maxima, not matched measurements. Reviews also note that the 530 does not fold and lacks ANC: do not choose it expecting active isolation for travel.

Before buying
Compare the final price, exact model, seller and Spanish or US package. If the 520 is substantially cheaper and you do not need LC3, saving money may matter more than the newer generation. Amazon buttons open searches: check the selected product and availability rather than assuming the first result is correct.

Frequently asked questions
Should I replace a working WH-CH520?
Not simply for a newer generation. Decide whether you need LC3 and whether the advertised battery difference justifies the actual cost.

Does the WH-CH530 provide active noise cancellation?
No. Reviews describe passive isolation, which depends on fit; that is different from active noise cancellation.
