Sony WI-C100 Review: The Ultimate Budget Wireless Neckband Earphones?
For many users, ultra-compact true wireless earbuds come with a catch: they are easy to misplace, offer limited single-charge battery life, and often suffer from spotty Bluetooth connections. The Sony WI-C100 Wireless In-Ear Headphones solve these issues by utilizing a comfortable, secure neckband form factor.
By prioritizing exceptional battery life, everyday splash resistance, and deep software customization over expensive active noise cancellation, these entry-level earphones offer an excellent mix of reliability and performance. Let’s evaluate if this budget-friendly model is the right choice for your daily listening needs.

Key Features of the Sony WI-C100
Sony designed these neckband earphones to provide a streamlined, worry-free user experience during long commutes and workouts.
- Massive 25-Hour Battery Life: The physical space inside the neckband modules allows for a high-capacity battery stack. On a single charge, the WI-C100 delivers up to 25 hours of continuous audio playback, easily outlasting almost any standard true wireless alternative.
- Digital Sound Enhancement Engine (DSEE): When musical tracks are compressed into standard streaming formats, high-frequency data is often lost. Sony’s integrated DSEE technology interpolates and restores these lost high-register details in real-time, creating a warmer, more balanced acoustic delivery.
- IPX4 Splash and Sweat Resistance: The internal circuitry and housing seams are coated to protect against multi-directional water splashes. This makes the earphones completely safe for heavy gym workouts, running in light rain, or casual outdoor hikes.
- Tactile In-Line Control Module: A physical three-button inline remote is integrated directly onto the left side of the cable. The raised tactile buttons let you easily adjust volume, play or pause tracks, skip songs, answer phone calls, and trigger your smartphone’s voice assistant without looking.
Advanced Software Optimization & Control
Linking the WI-C100 with the official Sony Headphones Connect smartphone app unlocks a level of personalization rarely found in the budget price tier:
- Custom 5-Band Equalizer: You can select from various pre-configured sonic profiles (such as Bass Boost, Excited, or Vocal) or manually adjust individual frequency sliders alongside a dedicated “Clear Bass” tracking wheel.
- Dolby Atmos and 360 Reality Audio: The software framework can use your smartphone camera to map your unique ear shapes. This optimizes spatial 360-degree music streams and cinematic multi-channel audio tracks when using compatible streaming services.
- Google Fast Pair & Swift Pair: The wireless chip supports instant pop-up pairing on Android devices and streamlined discovery protocols for Windows 10 and 11 computers
