What's in the box
TONOR names two wireless microphones in the title of its two-mic K20 page. The pages we used don't list the rest of the box or say how the mics are powered, so check the listing before you order.
Inputs and connections
TONOR lists four ways to play music into the K20:
- Bluetooth from a phone or tablet
- USB from a flash drive
- TF (microSD) card
- 3.5 mm AUX from any device with a headphone-style output
TONOR doesn't list HDMI or any video output, so the K20 doesn't show lyrics by itself. Read them on the phone or tablet that plays the song, or play a karaoke video on a smart TV and use the K20 for the mics. See how to connect a karaoke machine to a TV.
Power and battery
TONOR lists a built-in 7000 mAh rechargeable battery and rates it at up to 12 hours of music playback. Treat that as the maker's figure: run time changes with volume and use. Charge it fully the night before a party.
Who it suits and who should look elsewhere
The K20 suits backyard and living-room parties where everyone sings from a phone and two people share the mics. TONOR states its peak power as up to 250 W and lists a wooden cabinet, plus a disco ball and LED lights on the front.
Look elsewhere if you want lyrics on a built-in screen: the Singing Machine ISM9025 has a 10.1-inch touchscreen and HDMI, and our TONOR K20 vs ISM9025 comparison sets them side by side. For a smaller TONOR speaker with UHF mics, see the TONOR K6. More picks: karaoke machines with two wireless mics and battery karaoke machines for outdoors.
