The 3.5 mm Bluetooth transmitter for Switch can transmit the audio signal from Switch to Bluetooth headset or speaker. Not only does it adopt the dual-color style of Switch handle in color matching, but also the overall shape is designed according to Mario, the exclusive character in the Switch games. The familiar red hat and blue belted trousers make this product truly become an exclusive product for Switch. In addition to the above colors, the Switch controller comes in pink and green, so you can use Mario's brother Louiki's green hat on this unit.
