All-day wireless listening

Sony WI-C100 in-ear headphones deliver up to 25 hours of playback on a single charge. A 10-minute quick charge adds 60 minutes of listening time. Bluetooth connectivity provides a stable link up to 10 meters. The 9-millimeter drivers and DSEE processing restore detail lost during compression. IPX4 splash and sweat resistance handles workouts and commutes.

Commuters and casual listeners

The lightweight 20-gram neckband suits anyone who wants simple, long-lasting wireless audio without active noise cancellation. Built-in microphone and easy-access buttons handle calls and playback on the move. Buyers who need over-ear comfort, ANC for noisy travel, or a wired connection for zero-latency gaming should look at other form factors.

Fits daily carry essentials

Flexible neckband slips into a pocket or small bag alongside a phone and keys. Bluetooth pairing works with any compatible source device, no extra dongles required. On-board controls free the user from reaching for the handset to adjust volume or skip tracks. Microphone enables clear hands-free calls while the phone stays stowed.

Questions about this item

What Bluetooth source device do I need to pair with the WI-C100 since it has no wired jack?

The WI-C100 connects wirelessly via Bluetooth, so any phone, tablet or computer with Bluetooth audio output will work as the source.

Can I keep using my older wired headphones alongside the WI-C100 on the same device?

The WI-C100 is wireless only and the device you pair it with can still drive a wired headset through its own headphone jack or USB-C adapter if one is fitted.

How can I confirm the headphones are performing correctly after the first charge?

After charging, the indicator light shows battery status, the built-in microphone enables clear hands-free calls, and DSEE restores compressed high frequencies for improved sound quality.
