Hybrid Connectivity: They primarily run on Bluetooth (typically versions 5.0 to 5.3) for wire-free pairing with your phone, tablet, or laptop. However, if your battery dies, they also feature a 3.5mm AUX port so you can plug them directly into your device.

TF/MicroSD Card Slot: A unique feature often left out of expensive headphones—the P9 includes a built-in TF card slot. You can load an SD card with MP3 files and use the headphones as a completely standalone music player without needing a phone nearby.

On-Ear Controls: Physical buttons on the rim of the earcup allow you to skip tracks, adjust the volume, play/pause music, and answer calls hands-free.
