Editorial note
The Sony MDR-NC20 headphones stand out for their excellent sound quality, with a sensitivity of 102 dB and a wide frequency range from 16 to 22000 Hz. These features provide an immersive listening experience, ideal for music lovers. Additionally, their impressive battery life of 45 hours of continuous playback allows you to enjoy your favorite tracks without interruption, although the use of AAA batteries may be a drawback for some users who prefer rechargeable options. The ergonomic and lightweight design of 175 g also contributes to optimal comfort during long listening sessions. However, the island design may not suit everyone, with some preferring more discreet models. The 0.5 m cable length, while convenient, may limit usage flexibility, especially for those who wish to move freely while wearing them. In terms of connectivity, the choice of a wired connection may be seen as a disadvantage for those seeking the convenience and freedom of wireless headphones. Despite the use of neodymium magnets ensuring superior sound quality, some users might find the sound performance inferior compared to other high-end wireless models. Overall, the Sony MDR-NC20 offers a quality audio experience and good comfort, but a few aspects may not meet the expectations of all users, particularly regarding connectivity and usage flexibility.Score details
