Sony WI-C100 Wireless In-Ear Bluetooth Headphones

The Sony WI-C100 are lightweight wireless in-ear Bluetooth headphones with a flexible neckband, up to 25 hours of battery life, IPX4 splash resistance and a built-in microphone for hands-free calls.

Compact and comfortable, the WI-C100 blends reliable Bluetooth connectivity with Sony audio tools to keep music and calls clear throughout the day.

How long will the battery last during daily use?

The WI-C100 delivers up to 25 hours of playback on a full charge, which covers several days of commuting or a full work week of short listening sessions. Battery life depends on volume level and paired device settings, but quick top-ups are straightforward.

• Up to 25 hours continuous playback on a full charge
• Low-power consumption design for extended standby
• Fast and simple charging routine fits daily use

Will these hold in my ears and stay sweat- or splash-safe?

The WI-C100 uses snug silicone earbud tips and a balanced neckband shape to provide a secure, comfortable fit for many ear shapes. The IPX4 rating protects against splashes and sweat, making them suitable for outdoor walks and light workouts.

• Multiple earbud tip sizes included for a better seal
• Flexible neckband sits comfortably and keeps buds stable
• IPX4 splash- and sweat-resistance for everyday activities

How do they perform for calls and music quality?

These headphones include a built-in microphone for clearer hands-free calling and physical buttons for playback and volume control. Sony’s DSEE (Digital Sound Enhancement Engine) helps recover higher-frequency detail that can be lost in compressed tracks, while the Sony | Headphones Connect app lets you fine-tune EQ settings.

• Built-in mic for clearer conversations on calls
• DSEE restores subtle high-frequency detail in compressed audio
• App-based EQ adjustments for personalized sound

How easy is pairing and everyday operation?

Pairing is fast with Bluetooth Fast Pair support for compatible Android devices, and physical buttons on the neckband make play, pause, track skip and volume adjustments straightforward. The simple control layout keeps operation tactile and predictable without needing to reach for your phone.

• Bluetooth Fast Pair simplifies initial setup with Android
• Dedicated buttons for playback and volume on the neckband
• Stable wireless connection for routine commuting and calls

Who is this for? The Sony WI-C100 headphones are aimed at users who want a reliable, no-fuss wireless listening solution for daily life: commuters, remote workers, and casual exercisers who value all-day battery life, a comfortable neckband design, and simple controls. If you prefer compact earbuds with longer runtime and splash protection over fully wireless stems, the WI-C100 offers a practical balance of comfort, call functionality and audio enhancement tools without complexity.
