Manual of product WH-CH400
Editorial note
The Sony WH-CH400 headphones stand out for their immersive sound quality, thanks to a frequency range of 20 to 20,000 Hz and 25 mm dynamic drivers. Their in-ear coupling and closed acoustic system ensure prolonged listening comfort, ideal for extended music listening sessions. Additionally, their 20-hour battery life during continuous audio playback is remarkable, although the 4.5-hour charging time may seem long for some users. However, some drawbacks must be taken into account. The absence of standard audio connectors like 3.5 mm and 6.35 mm limits their compatibility with certain devices, which may disappoint users who prefer a wired connection. The Bluetooth 4.2 version, while effective, is less performant than newer versions, which can lead to latency issues with some modern devices. Furthermore, the omnidirectional microphone may pick up too much ambient noise, detracting from call clarity. Overall, the Sony WH-CH400 offers good value for money, with interesting features for casual users. However, audiophiles seeking more precise sound reproduction may be less satisfied. The flexibility of use is an asset, but it is essential to consider the limitations in terms of connectivity and audio performance to make an informed choice.Score details
