Everyday Wireless Neckband Headphones

The Sony WIC100/B is a lightweight in-ear neckband headset built for all-day listening. It connects via Bluetooth and weighs 20 grams for a barely-there feel. A flexible band rests securely around the neck while you move. The IPX4 rating protects against splashes and sweat during workouts or commutes.

For listeners who want simple.

This suits anyone who values 25 hours of playback and a quick 10-minute charge that adds 60 minutes of use. Built-in buttons handle playback, volume and calls without reaching for a phone. DSEE processing restores detail lost in compressed files. Buyers who need active noise cancellation or a wired connection option should look elsewhere.

25-hour battery life with IPX4 splash resistance

The lithium-ion battery delivers 25 hours of continuous operation on a full charge. A short 10-minute top-up provides up to 60 minutes of extra listening when time is short. The IPX4 rating means rain and sweat will not interrupt your session. This combination of endurance and durability decides if the headset matches your daily routine.

Questions about this item

What comes in the box with the WI-C100/B and is anything extra needed?

The headphones ship with a USB charging cable and multiple earbud tip sizes so you can choose the fit that seals your ear canal. No separate audio cable is required because the model has no jack and connects only by Bluetooth.

Which version or capacity should I choose for the WI-C100/B?

This model is offered in a single black version with a fixed 25-hour battery and 9-millimetre drivers; there are no alternate capacities or colour options to select.

What does the 25-hour battery figure mean in daily use?

You can expect up to 25 hours of continuous playback per full charge, and a 10-minute quick charge adds roughly 60 minutes of listening when the battery is low.
