Apple AirPods Pro 2

At $249, it represents one of the more affordable options in the category while delivering strong overall performance. In our testing, the AirPods Pro 2 shows particular strength in speech clarity for quiet environments, scoring 4.2/5—a strong result that sits 1.38 points above the category average. Music streaming is where this device truly excels, earning 4.4/5 and outperforming the category average by a substantial 2.48 points. Feedback handling is excellent at 5.0/5, meaning users should experience virtually no whistling issues. The device does have limitations. Own-voice comfort scores 1.9/5, which is low in absolute terms and 0.61 points below the category average—users may notice their own voice sounds different or boomy. Speech in noise performance is above average for the category at 2.3/5 (+0.77 points), but this remains a mixed result in absolute terms, suggesting challenging listening environments will still be difficult. The AirPods Pro 2 is best suited for consumers already in the Apple ecosystem who want hearing support primarily in quieter settings and value excellent music and media streaming. Those frequently in noisy environments or sensitive to own-voice changes may want to consider alternatives.
