Neckband Bluetooth headphones are prominent for the call quality and battery life, Sony last year joined the mid-range neckband headphones market with the Sony WI-C400. Previously Sony announced two high-end neckband models, the active noise cancelling WI-1000X and the WI-H700 but in terms of battery life none of them can last as long as WI-C400.
Like most of Sony wireless headphones, the WI-C400’s control is intuitive and easy to use. While the WI-C400 are generally decent for fit and comfort and their call quality is above average, the sound quality would be better with more bass and pleasant treble.
Design and feature
The neckband is not as flexible as Skullcany Ink wireless or LyreBeats-NB1, instead the band is hard-plastic case. Nevertheless it is pretty lightweight, and it feature a motor that vibrates when there is a call. The neckband is basic and solid. A nice feature that you can shorten the cable by cable adjuster and stopper (the ball) – keep things neat around your neck.
The control buttons are on the left, including power-button and volume controls they are responsive and feel solid once pressed. The mic is also on the left-remote, the earbuds are compact and small but feel quite cheap (just like other cheap Sony earbuds).
Spec that matters
Driver size: Dynamic 9mm
Frequency response: 8Hz – 22kHz
Charing time: 4.5 hours
The battery life of C400 is rated at 20 hours, which is longer than most wireless neckband headphones’s battery in the category. But it also comes with a compromise that the time for charging is 4.5 hours, and no quick-charging feature is built in.
The C400's bass isn't plentiful, but it is still there and punchy. The mid-range is smooth and natural. The treble is dedicated and quite aggressive and sometimes feel edgy.
The Bottom Line: Focus on battery life, easy of use the Sony C400 offer the standards that every neckband Bluetoth headphones offer. And what makes them worth more is solid design, balance sounding profile and comfortable fit.
