DAP Silent Disco Headphones (reciever) 3 channels - Need separate transmitter

The DAP Silent Disco Headphones are headphones intended for use in a silent disco setup in combination with the DAP Silent Disco Transmitter (D1820). With a range of up to 450 meters, listeners can enjoy a huge freedom of movement. The headphones are capable of producing a loud and powerful sound, while the soft ear pads suppress external noise. The volume control allows listeners to adjust their individual listening volume. With 3 selectable channels, the headphones can be used in multiple applications, like a multi-DJ setup, multiple simultaneous lectures, (tour) guide applications, and so on.

The headphones’ shells have RGB LEDs that show the selected channel by colour. The colour can be overruled by the DAP Keypad for LED Control of Silent Disco Headphones (D1822) that can be connected to the transmitter. The shells can be folded in to save storage space. The internal 500-mAh Li-ion battery provides power up to 8 hours, depending on the volume. It can be charged in 2.5 hours via the included cable using a 5 V USB power supply (50040, not included), or the dedicated DAP Charger for Silent Disco Headphones (D1823) that can charge up to 20 headphones simultaneously.
