Technology & Features
BEAST™ Mode (Low Latency)
BEAST™ Mode is a low latency mode infused with virtual 3D sound, built for gaming. A single press of the dedicated BEAST Mode quick-switch button activates low latency mode with a “BEAST Mode” prompt confirming activation; press the same button again to switch back to normal music mode. It’s ideal for entertainment and casual gaming, but not designed for professional gaming equipment needs.
EQ Sound Modes
Rockerz 375 offers two sound profiles: Signature Sound Mode (boAt’s default bass-centric mode) and Balanced Mode, better suited for podcasts, news, and voice-based media. Short press the dedicated EQ button to switch between the two modes.
Multi-Device Call Switching
If Rockerz 375 is connected to two phones and a call comes in on the second phone while you’re already on a call with the first, press the MFB to switch to the second call while placing the first on hold. You can continue switching between the two calls using the MFB. Press and hold the MFB to transfer an ongoing call between the earphones and the phone.
