The Electro-Harmonix R&B Buds True Wireless In-Ear Headphones leaves the wires behind to deliver true wireless stereo sound in a portable form factor. You can stream music to these headphones via any Bluetooth-compatible mobile device. If that device is your smartphone, you can utilise the built-in microphone for hands-free calls. The microphone can also be used to send voice commands to your device's digital assistant.

The R&B Buds can run for up to 5 hours on a full charge, and the included charging case provides another 15 hours. That's up to 20 hours of power before anything needs to be plugged in and recharged. Thanks to the lightweight and sweatproof construction, you can wear these headphones on the go or at the gym. No matter where you use them, built-in controls let you control both audio playback and wireless calls.
