Editorial note

The Sony MDR-AS21J headphones stand out for their superior sound quality, providing an immersive listening experience, whether for music, podcasts, or calls. Their comfort and fit are particularly suited for prolonged use, especially during sports activities. Additionally, Sony's reputation for innovation and reliability reassures users about the quality of this product. However, some drawbacks deserve to be highlighted. Bass enthusiasts might be disappointed by the lack of depth in the bass. Furthermore, comfort may be limited for users with sensitive ears, and the open design of the headphones allows a lot of ambient noise to pass through, which can detract from immersion in noisy environments. The cable, on the other hand, can easily get tangled, making transport less convenient. In terms of performance, the headphones offer good audio quality for everyday use, although this may not satisfy demanding audiophiles. Ease of use is a strong point, thanks to the included manual that allows for quick handling. For the price, the Sony MDR-AS21J represents good value for money, offering an acceptable audio experience and reasonable comfort for everyday users.
