The RP-HF400B Bluetooth On-Ear Headphones use 30mm drivers with neodymium magnets to provide clear sound while the acoustic bass control filter helps deliver sharp bass notes. They connect to your device via Bluetooth 4.1, enabling you to stream music wirelessly. One of the earcups features a built-in microphone for making phone calls. The earcup also features buttons for raising or lowering the volume, as well as answering calls, ending calls, playing music, and pausing music.
A micro-USB charging cable is included and can recharge the headphones' internal lithium-ion polymer battery in approximately 2.5 hours. The battery provides approximately 20 hours of playback and 15 minutes of charging can provide up to two hours of playback. The headphones' earpad housings conveniently swivel, allowing the headphones to fold flat for travel.
