Compatibility

Use Bluetooth to connect compatible devices such as a smartphone, tablet, or television. For other playback options, the machine supports AUX input, USB flash drives, and TF cards, as well as FM radio. TWS mode lets you connect two units for dual-channel audio, a useful setup when you want sound from two speakers around a gathering.

Who it’s for

This system suits adults and kids who want an approachable way to add singing to family time, birthdays, home parties, and small indoor or outdoor gatherings. Having two wireless microphones makes it practical for duets, turn-taking, or group games, while the shoulder strap and carry handle make it easier to move between rooms or take along to an event. The LED effects bring a party-focused look without requiring a separate lighting setup.

It also works for listeners who want more than a karaoke-only player. Bluetooth, AUX, USB, TF card, and FM playback give you several ways to use the speaker when the group is listening to music rather than singing.

Before you decide

Can it play music without Bluetooth? Yes. You can use AUX input, a USB flash drive, a TF card, or FM radio, in addition to Bluetooth playback.

Are wireless microphones included? Yes. The package includes two wireless microphones and four AA batteries for them, so two people can take part in karaoke.

Can the lights be changed? Yes. A dedicated button switches among five dynamic LED effects, which also sync with the music’s rhythm.

When it makes sense

Choose the K303-N when you want one portable setup for karaoke and everyday music, with two microphones for shared singing and multiple playback choices for different devices or media. Its compact dimensions, carry handle, and shoulder strap support moving it between home spaces or bringing it to a gathering, while adjustable bass and treble help you shape the sound for the occasion.
