Connect the wireless microphones to the karaoke machine, then connect the machine to the TV with Bluetooth or an AUX cable. The TV plays the karaoke video and shows the lyrics, while the microphones send your voice to the machine's speaker.
Switch on the machine and the microphones
The machines in this guide come with 2 wireless microphones each. Switch the machine on, then switch the microphones on so they connect to the machine. The HWWR machine uses 2.4GHz wireless microphones, and the JOIN&JOY machine has separate mic and music volume knobs, so set the mic volume on the machine before you sing. The Delighkidz machine also includes 2 wireless microphones with adjustable mic volume.
Connect the machine to the TV with Bluetooth
Open the Bluetooth settings on the TV and pair the karaoke machine as a Bluetooth speaker. The JOIN&JOY machine pairs with TVs over Bluetooth 5.3 up to 100ft away, and the Delighkidz machine pairs with a TV, phone, tablet or PC over Bluetooth 5.3. The HWWR machine connects to a compatible TV through Bluetooth audio output. Once paired, play a karaoke video on the TV and the lyrics show on the TV screen while the sound comes from the machine.
Connect the machine with an AUX cable
The HWWR machine connects to a compatible TV through an AUX audio cable. Plug the cable from the TV audio output into the AUX input on the machine, then select the AUX input on the machine. The JOIN&JOY machine has USB and AUX inputs, and the Delighkidz machine supports AUX, USB and a TF card, so the cable connection works on each machine.
Play a karaoke track and balance the sound
Play a karaoke track from the TV, a phone or a USB stick and sing into the microphone. Use the mic volume knob to set your voice against the music, and use the music volume knob for the track. The JOIN&JOY machine has echo effects and bass and treble adjustments, and the Delighkidz machine has a reverb effect and a vocal removal function that reduces the original vocals on a track. Adjust the echo or reverb until the voice sits with the music.

Frequently asked questions
Can I connect a karaoke mic directly to a TV?
A wireless microphone connects to the karaoke machine, not to the TV. The machine then connects to the TV with Bluetooth or an AUX cable, and the TV shows the lyrics while the machine plays the sound.
Why is there no sound from the TV after pairing?
Check that the TV is sending audio to the machine over Bluetooth or the AUX cable, and that the machine is on the right input. Raise the music volume on the machine and the volume on the TV, then play a track to check the connection.
Can two people sing at the same time?
Yes. Each machine comes with 2 wireless microphones, so a duet works without sharing a mic. The HWWR machine uses 2.4GHz wireless microphones, and the Delighkidz machine includes 2 wireless microphones with adjustable mic volume.
How long does the battery last on a karaoke machine?
The JOIN&JOY machine gives 8+ hours of playtime, and the HWWR machine gives 24+ hours of use. For the HWWR machine, battery life depends on volume, lighting and playback conditions.
