If you own a KBEATBOX system like the CS200-PU (V1, V2, V3), CS-286PLUS, or KB-39NEO, you’ll already know they’re fantastic all-in-one karaoke speakers that come standard with two wireless microphones. But unlike higher-end models—such as the CS-366PLUS, FLAC 36, Acoustic 3, HiNet 450 Gen2, or the CB41/51NEO—these units don’t include an extra microphone input.
That means, traditionally, you were limited to just two singers at a time. No easy way to plug in a wired mic, and no way to add an external wireless system like you can on the models mentioned above.
But not anymore.
The New Solution: Sonken EZY Mic 5.2
Thanks to the brand-new Sonken EZY Mic 5.2 dual-wireless microphone system, you can now expand these KBEATBOX units to four simultaneous singers—even though they don’t have a dedicated mic port.
How It Works
The EZY Mic 5.2 connects directly via the AUX Line Input on your KBEATBOX speaker. It’s plug-and-play:
-
Connect the EZY Mic 5.2 receiver to the AUX input on your KBEATBOX.
-
Switch the speaker to AUX Mode.
-
Start singing—now with two additional wireless microphones.
Even better, the EZY Mic 5.2 operates on its own unique frequencies, so it won’t interfere with the two factory-included KBEATBOX wireless microphones.
What About Bluetooth Streaming?
Here’s the clever part.
Because the KBEATBOX needs to be in AUX Mode, its own Bluetooth audio input is disabled. But the EZY Mic 5.2 includes built-in Bluetooth, so you can still play your karaoke tracks:
-
Simply pair your phone/tablet with the EZY Mic 5.2 Bluetooth,
-
Your music streams through the EZY Mic system,
-
And everything flows into the KBEATBOX via AUX—music + all four microphones together.
This setup works perfectly for anyone who uses Bluetooth as their main audio source, which is the vast majority of home karaoke users.
Important Note
This solution only works when your audio source is Bluetooth.
If you're using optical input from a smart TV or other non-Bluetooth sources, those signals won’t pass through while the KBEATBOX is in AUX mode.
For Bluetooth users, however, it’s a brilliant and simple way to get four singers on stage at the same time—ideal for parties, family nights, and big group sing-alongs.
Final Thoughts
It’s great to finally have a clean, reliable option for expanding models like the CS200-PU V3, CS-286PLUS, and KB-39NEO beyond the standard two-mic limit. With the Sonken EZY Mic 5.2, you can enjoy the same flexibility as the models that include extra mic inputs—without needing to upgrade your speaker.
Don’t own a KBEATBOX? If your speaker has a Line In (AUX) or RCA stereo audio input, the Sonken EZY Mic 5.2 will work for you too!
More singers. More fun. More KBEATBOX.
