We offer two different transmitters: a transmitter on electricity (most suitable for DJ/festivals) and a wireless transmitter. With all the wired transmitters, we provide a standard 3.5mm headphone jack cable which you can easily plugin into your phone, laptop or iPad. Choose your playlist, hit play and turn it up (your device should normally be at 70-100% of full volume for optimum results). If you have a more recent Apple or Android device without a headphone jack, you may require an adaptor to connect your phone to the transmitter. These adaptors are usually provided in your original phone packaging or are available cheaply online. Please note, we do not supply these adaptors directly. Our wireless transmitters can simply be connected with Bluetooth or with AUX.
