Product description
More than music, K400 is a portable PA system built to connect with every crowd. Use the wireless mics for shared moments and audience interaction, or go hands-free to teach, host, guide or present. From casual gatherings to organized events, K400 brings clear voice and rich sound wherever you go
Three wireless mics give you more ways to connect. Share the handhelds when two voices need the spotlight, or switch to the hands-free headset when freedom to move matters most. From one speaker to the next, K400 gives you the flexibility to match the moment without being tied to one setup
K400 microphone and speaker system supports any two wireless mics at the same time, so you can adapt the setup to the moment. Choose two handhelds or pair one with the headset for public speaking, hosting, karaoke, outdoor group activities and more—giving you the right setup for work, events or fun
Hate wrestling with settings? K400 is incredibly easy to use. Connects via Bluetooth, USB, or AUX in seconds. One-touch EQ adjusts instantly; TWS pairs two for massive stereo. Smart beeps confirm power, pairing, mode, volume limits—and you can turn them off or on. Battery level shows on screen
Weather doesn’t always cooperate—K400 does. IPX6 water resistance and a rugged build handle sudden rain, splashes, dust, and bumps. Whether you’re relaxing poolside, heading to the beach, or camping with friends, the music keeps playing and the good times keep rolling wherever the day takes you
Built to move when you do. At just 7.6 lb, the K400 portable loudspeaker has a comfortable handle and rugged, compact design that’s easy to take from classrooms and community events to campsites and outdoor activities. A practical portable sound system for wherever your voice or music needs to go
Make Your Voice Carry Without Pushing It: Whether you’re teaching a class, leading a group, hosting an event or speaking outdoors, this 150W portable voice amplifier delivers clear, powerful sound that helps everyone hear you. Crisp highs keep speech and announcements clear, while rich bass gives music the presence it deserves—so one PA speaker works for both voice and sound
Choose the Mic That Fits the Moment: Some moments call for a handheld mic; others are easier with a headset. This microphone and speaker set includes two wireless handhelds plus one headset, so you can adapt the setup for teaching, coaching, presentations, hosting or group activities. Use any two at once—speak solo, share the floor or bring another voice into the conversation
Rain or Shine, This Portable PA System Has Your Back: The best activities don’t always happen indoors. Whether you’re leading outdoor training, setting up a community event or heading to camp, IPX6 water resistance plus a rugged, shock-resistant design helps K400 handle changing weather, splashes and everyday bumps. Built for real-world use, so you can focus on your group instead of worrying about your gear
More Than Voice—Ready for Music & Fun: This Bluetooth speaker with microphone goes beyond voice amplification. Stream music from your phone, connect through USB or AUX, or link two K400 speakers with TWS for wider stereo sound. Rich bass and clear highs make it ready for background music, group activities, family gatherings or karaoke—so one system can move easily from work and events to music and fun
Built to Move and Keep Going: From one class, field or event to the next, this portable microphone and speaker is made to travel with you. At just 7.6 lb, the carry-friendly design is easy to move, while the built-in 5000mAh battery delivers up to 6 hours of playtime. Handheld mics run up to 12 hours and the headset up to 5–7 hours, helping you stay ready through long days and changing activities
