The Sony WI-C100 is a neckband-style wireless in-ear headphone with a flexible band that rests behind the neck and a short cable to each earbud. It is built for long listening sessions: Sony rates the battery at up to 25 hours, and a 10-minute quick charge gives about 60 minutes of playback. The DSEE processing and the Sony Headphones Connect app's equalizer let you adjust the sound, and the earbuds are splash-resistant. It suits commuters, students and casual listeners who want simple, durable everyday headphones rather than noise cancelling or a fully sealed fit. Against true-wireless rivals it trades pocketability and a cable-free fit for battery life and a lower-risk design; against wired sets it adds Bluetooth and app control.

Owners generally treat the WI-C100 as a solid everyday neckband headphone: they praise the long battery life, the light fit and the app's sound customization. Complaints center on the lack of noise cancelling, average call quality and the cable-and-band design compared with true wireless buds.
The Sony WI-C100 is a pair of wireless in-ear headphones with a flexible neckband. They connect over Bluetooth and have a built-in microphone for hands-free calls. Buttons on the headphones play and pause music, skip tracks, adjust volume and answer calls.
Battery life is up to 25 hours, and a 10-minute quick charge gives up to 60 minutes of playback. The headphones have an IPX4 water resistance rating, so they handle splashes and sweat. DSEE (Digital Sound Enhancement Engine) restores high frequencies lost in compressed music. The sound is balanced across the frequency range, with clear, natural vocals.
The Sony | Headphones Connect app offers preset sound settings and an equalizer where you can create and save your own. A button connects to your smartphone's voice assistant. Fast Pair makes pairing with Android devices quick, and the app can make the headphones ring or show their last recorded location. Swift Pair does the same for Windows 11 and Windows 10 PCs. The headphones support 360 Reality Audio. With the Sony | 360 Spatial Sound Personalizer app, they can create a personal spatial sound field when paired with BRAVIA XR TVs. Connecting a Sony WLA-NS7 wireless transmitter to a BRAVIA XR TV gives a Dolby Atmos experience.
