Engineered for Adult Living Rooms, Not the Toy Aisle

Every detail of the StageDock K1 eliminates the tangled cords, dead batteries, and harsh distortion that keep ordinary karaoke machines stuffed in a closet.

Self-Charging Gunmetal Mic Docks

Both 248g CNC-anodized wireless mics live and recharge via gold pogo-pins right inside the speaker top. Lift them out and they auto-pair instantly.

15° Silicone Tablet Lyric Cradle

Skip overpriced built-in screens. Drop any smartphone or cased 12.9-inch iPad into the deep top slot to stream free YouTube or Apple Music lyrics.

<4.2ms UHF & Anti-Howl DSP

Dedicated dual-channel UHF links prevent lip-sync delay while onboard notch filtering kills high-pitched feedback even two feet from the grille.

60W Bi-Amped Acoustic Warmth

A 5.25-inch long-throw woofer, 2.0-inch silk-dome tweeter, and warm tube-amp amber ring make it your favorite everyday speaker between parties.

Finally a karaoke setup that doesn't look like a neon carnival ride

I didn't expect the microphones to feel like real weighted stage metal and charge automatically just by dropping them into the top of the speaker—zero AA batteries or loose cords! The warm amber ring light on the front woofer looks like a high-end tube amp sitting on our living room coffee table instead of those tacky spinning rainbow disco balls. The top slot holds my 11-inch iPad with a thick case on it without wobbling even when the bass is pumping.

Zero vocal lag compared to our TV soundbar

We tried using a Bluetooth mic with our TV soundbar last month and the half-second vocal delay made it impossible to sing. This StageDock K1 has zero lag the second you lift the mics out of the dock. Both mics auto-pair the instant you pull them out of the top holes—no menu diving, no Bluetooth pairing codes for the mics. It sits right on our Walnut media credenza and looks like a real studio monitor.

Paid for itself in one Friday night

We saved at least $250 skipping the karaoke bar downtown for my wife's 40th and ended up having ten times more fun in our own living room. Every cheap karaoke machine we bought online screeched the moment you walked within five feet of the speaker, but the anti-howling chip in this actually works in a small room.

The one-button vocal remover is crazy good

You don't even need special karaoke tracks if you don't want them. The one-button vocal remover is crazy good—we just played regular 90s playlist tracks off Spotify and it stripped the lead singer right out so we could duet. Love that one single USB-C cord charges the speaker AND both docked microphones at the same time.

Kids and 70-year-old grandparents used it for 4 hours straight

My kids and my 70-year-old parents used it for four hours straight over the weekend. There is no complicated app to download—you just open YouTube, search 'song name karaoke', drop the iPad in the groove, and sing. The leather strap feels super sturdy and the whole cube weighs under 5 pounds, so we carry it from the basement bar out to the patio firepit in one hand.

Doubles as our everyday living room speaker

What sold me is that you can switch the warm amber light down to a soft glow or turn it completely off. Monday through Thursday we use it as a regular Bluetooth speaker for podcasts and acoustic playlists, and on Friday nights we pop the two gunmetal mics out of the top dock and go crazy.

Serious punch for a 4.8 lb cabinet

Honestly shocked by how much clean mid-bass comes out of a box this compact. My only minor wish is that it came with a hard travel case for road trips, though the built-in leather strap makes carrying it from room to room effortless. The metal mics have a really satisfying heft to them.

No more hunting for AA batteries mid-party!

Our old wireless mics ate through AA batteries every single weekend and rolled off the coffee table constantly. Having the two charging docks built right into the top of the StageDock K1 means the mics are always at 100% battery and always right where they belong.

Studio reverb makes average singers sound great

The built-in echo and vocal tuning smooths out rough notes without sounding robotic. Even my brother-in-law, who usually refuses to touch a microphone, ended up singing three 80s rock ballads back-to-back because the vocal mix blended so well with the backing track.

Holds a 12.9-inch iPad Pro securely

I was worried the top lyric groove might be too shallow for a big tablet, but it holds our tablet rock-solid at the exact viewing angle you need while standing or sitting on the couch. Even with the volume cranked up to 80%, the tablet doesn't vibrate or slide at all.

Frequently Asked Questions

Do I need to pay for a monthly karaoke app subscription to get lyrics?

No. The StageDock K1 never locks you into paid software. Simply connect any phone, tablet, or Smart TV via Bluetooth 5.3 and stream millions of free karaoke lyric videos on YouTube, or use Spotify, Apple Music Sing, or Karafun.

Do the wireless microphones need AA batteries or separate charging cords?

Never. Both anodized gunmetal microphones house built-in 1,200mAh lithium cells and charge automatically via recessed gold pogo-pins whenever you drop them into the top speaker docks. One USB-C cable charges the speaker and both mics simultaneously.

Can I turn the warm LED woofer light completely off for everyday music?

Yes. A dedicated lighting button on top lets you toggle between Beat-Synced Warm Amber, Soft Steady Candlelight Glow, or 100% Off so it serves cleanly as an architectural living-room speaker.

Will the top lyric cradle hold a large iPad with a protective case on?

Yes. The 16mm-deep silicone-lined channel is angled at 15 degrees and engineered to hold smartphones and tablets up to 12.9 inches—even inside thick protective cases—without tipping or rattling during heavy bass.

Can we sing to normal songs if there isn't a karaoke version available?

Yes. Pressing the top AI Vocal Cut button isolates and reduces the original lead singer's voice by up to 85% in real time on standard Spotify or MP3 tracks while keeping the drums and instruments clear.

Can I display the lyrics on my big-screen living room TV?

Absolutely. You can stream YouTube karaoke right on your Smart TV and send the TV's audio to the StageDock K1 via Bluetooth or the included braided 3.5mm AUX cable, with zero lag on both wireless microphones.
