Bluetooth 5.0 audio transmitter, compatible with PS4 and Nintendo Switch. - Model: BT-W3 - Bluetooth Version: 5.0 - Compatible Devices: PS4, Nintendo Switch, PC, Mac [Contents] - Main unit, USB-A connector, Instruction manual *Bonus: Microphone jack I bought this used hoping to use wireless earphones for voice chat on my Switch, but I couldn't get the microphone to work. I'm not sure if I'm doing something wrong or if the microphone is broken. Therefore, I'm offering the microphone jack as a bonus. Everything else worked fine. As you can see in the image, there is some damage to the box. I am a private seller, as stated in my profile (^_^;). Please understand that this is a used item from a private seller before purchasing (^-^ゞ #Transmitter #AudioTransmitter
