Manual of product WI-C400
Editorial note
The Sony WI-C400 headphones stand out for their wireless design and Bluetooth connectivity, providing users with great freedom of movement and comfort of use. Their impressive battery life of 20 hours of continuous audio playback allows for enjoying music and calls without interruption, which is a major asset for those seeking an extended audio experience. In terms of performance, the closed acoustic system and in-ear coupling ensure optimal sound immersion, making each listening experience enjoyable. Their lightweight of 35 g also contributes to prolonged comfort, although the lack of a foldable feature may make transport less convenient. However, some drawbacks should be considered. The absence of RF connectivity and a 3.5 mm connector may limit compatibility with certain devices, which might not suit all users. Additionally, the built-in microphone, while convenient for calls, is not equipped with noise-canceling technology, which can affect sound quality in noisy environments. Finally, the 4.5-hour charging time may be perceived as long for those who prefer quick use. Overall, the Sony WI-C400 offers good value for money, with solid features, but it is essential to consider these limitations before making a choice.Score details
