Forbrain headphones are primarily designed for cognitive and sensory enhancement purposes, using bone transmission technology and a built-in microphone for voice feedback. Here is an overview of the connectivity options offered: Standalone | Forbrain headphones are self-contained and do not require connection to external devices for their primary operation. All necessary components, including microphone and bone transducers, are integrated into the headphones themselves. This makes the headphones easy to use and portable Reload | Forbrain headphones include a USB-C port for charging the built-in battery. The USB connection is used exclusively for charging the device, and not for data transfer or audio connection to external devices No wireless connectivity | With forbrain you can speak independently into the headset microphone, get support thanks to the external microphone or listen to lessons and courses via a 3.5mm jack cable
