Ergonomically Engineered

Thanks to our ‘Ergofit’ design, the B120W wireless earphones sit snugly and discreetly in your ears. They’re made to keep you immersed in music and chat, or whatever else you choose to do.

 

Elevate Your Sound

Despite their compact size, the combination of 7mm dynamic drivers and XBS (eXtra Bass System) tech means that the B120W has plenty of depth to bring your tunes to life and transport you to another world.

 

Over a Day’s Power, in Your Pocket

With up to 6.5 hours of battery life in the earphones themselves and an extra 19.5 hours’ top-up power in the compact storage case, the B120W will keep you in music, podcasts and chat all day. And all night.

 

Built for Your World

Made to the IPX4 water resistance standard, the B120W is perfect for your intense workouts in the gym – or outside on a walk home in the rain.

 

Swift and Secure Connection

Using Bluetooth^® 5.3 wireless tech, the B120W headphones quickly connect to your smart devices and provide a stable connection. They also allow for higher quality performance from both music and calls than earlier versions of Bluetooth.

 

Easy Touch Control

The B120W has touch sensors on both earphones so you can quickly switch between music and calls. It’s easy to adjust the volume, pause or skip tracks.

 

Voice Assist

With both Siri and Google Assistant compatibility, the B120W is designed to work with your smartphone. A simple tap to the side of an earphone, followed by your assistant’s ‘wake words’ will bring it to life.

 

Compact Design

With an extra 19.5 hours of battery life in the case and quick USB-C charging, the B120W earphones are as flexible as you. The case’s smooth low-profile shape means it’s easy to pop into your jeans pocket or smallest bag.
