Karaoke Machines With Two Wireless Mics
Two wireless mics in the box means duets from the start, with no cables across the floor. The real difference between machines is how the mics are powered: self-charging, rechargeable, or AA/AAA batteries.
How the mics are powered
- Self-charging: Ikarao Shell S1 (charges when docked, per the maker).
- Rechargeable: Singing Machine ISM9025.
- AAA batteries: TONOR K6 (not included).
- Check the listing: TONOR K20 and K9, and the ISM9011 (batteries not included).

FAQ
Are UHF mics better than Bluetooth mics?
They work differently. UHF uses its own radio band, while Bluetooth mics pair like headphones. Makers quote range and battery figures, and we list them where published.
Can I use a third microphone?
Some machines add wired jacks. The ISM9025 lists two extra wired-mic jacks.
Do wireless karaoke mics lag?
Makers don't publish latency figures for these machines, so we can't compare them. Keep the mic near the machine and away from other wireless gear.
