RZ-B120WDE-K - Digital Wireless Stereo Earphones

Our new RZ-B120W wireless earphones are for people on the go - who demand long battery life, to be free of wires and want simple fuss-free operation no matter what the day throws at you. Despite their compact size, and close fit to the ears, there's also impressively powerful bass performance thanks to XBS.

 

Ergonomically Engineered

Thanks to our 'Ergofit' design, B120W wireless earphones sit snuggly and discreetly in your ears. They're made to keep you in music, and chat, 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 B120W have 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 top-up power in the compact storage case, B120W are ready to keep you in music, podcasts and chat all day. And all night.

 

Built for Your World

Because they're made to the IPX4 water resistance standard, B120W are 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, B120W quickly connects to your smart devices and provides a stable connection. It also allows for higher quality performance from both music and calls than earlier versions of Bluetooth.

 

Easy Touch Control

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, B120W are 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, 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.

Low volume, tinny, no bass, many other issues.

This product gives no stats for dB and there's a reason... the max volume is LOW. Out of the box the sound is terrible... tinny, weak, no bass even though it promotes it's XBS bass. I have $10 wired earbuds that sound better. Wore these on the bus and the bus easily drowned out any music via my phone on max volume. Add frustrating touch controls that interpret 3 taps (increase volume) as 2 taps (decrease volume) + 1 tap (pause). The size of the earbuds are small which is fine but the piece that goes in your ear is also tiny which means they fall out constantly regardless of the size of the earpiece cover you use.
