## Description

Product description

Review: Works awesome....so far - This was a second attempt to buy a good karaoke machine. The last one, Masingo brand, the mics didn't allow any kind of distance from the base. More than 2 feet away and the mics would stop working. After reading some reviews, I gave this one a go. Boy am I glad i did! First of all, I really like the compactness and portable nature of this unit. Very easily schlepped around. The unit is very sturdy and well built, don't see anything external breaking soon. Had no problem connecting our devices via bluetooth. The sound is amazing! The sound is clear with a good bass, perfect for a house party or backyard party. The mics are fantastic! They have controls for a speaker volume, mic volume, echo and voice enhancement. The only time the mics cut out was when someone other than the singer was standing right in front of the speaker blocking the signal to the singer. The unit says that mics can reach up to 10 meters. In reality, the singers would and should be closer than this distance. We had no issues with being about 15 feet away from the speaker. The unit comes with the standard wires to plug into the wall and/or usb ports for power and charging. Haven't had the unit long enough to test battery life from a charge. This unit was totally worth the extra money. Hopefully, it will hold up in the long run.
Review: Awesome machine - Awesome Karaoke Machine, excellent reverb and echo effect. Awesome volume control on both mics and the machine itself

## Features

- 【RICH, BALANCED SOUND FOR EVERY GATHERING】Experience the depth of 60W balanced audio designed to fill your outdoor space with clarity. Unlike smaller, thin-sounding speakers, the K666 delivers a solid acoustic presence that carries beautifully across a backyard or campsite. Whether it’s a family BBQ or a weekend getaway, the rich sound ensures your music and vocals are heard with premium texture and zero distortion
- 【SING WITH CONFIDENCE: UHF CLARITY & VOICE BEAUTIFIER】We believe everyone should enjoy the spotlight. This system features ultra-stable UHF wireless microphones—preferred for outdoor use due to their superior range and interference resistance. With the built-in Voice Beautifier function, your vocals are subtly polished for a natural, effortless tone, giving you the quiet confidence to sing your heart out in any environment
- 【EFFORTLESS CONTROL AT YOUR FINGERTIPS】Great entertainment should be seamless. With integrated controls directly on the microphones, you can adjust volume, echo, and voice effects without ever walking back to the speaker. This is especially convenient for outdoor settings where the speaker might be placed a few feet away. Stay relaxed, enjoy the conversation, and manage your performance from where you stand
- 【A SOPHISTICATED ADDITION TO YOUR HOME DECOR】Designed with an understated elegance, the K666 eschews flashy, distracting lights for a sleek and timeless aesthetic. At approximately 13.86 x 7.87 x 6.89 inches and 10 lbs, its solid construction ensures it stays grounded on any surface while minimizing vibration. When not in use for karaoke, it blends perfectly into your bookshelf as a premium Bluetooth speaker for relaxing background music

### ⭐⭐⭐⭐⭐ Awesome machine

Awesome Karaoke Machine, excellent reverb and echo effect. Awesome volume control on both mics and the machine itself

### ⭐⭐⭐⭐⭐ Great Speaker, EXCELLENT customer service
*by J***Y on November 4, 2022*

After doing a considerable amount of research, I bought this Karaoke Machine last year and could not be happier with my purchase. It's not my first one as I bought another highly rated system 3 years ago that only lasted a year and was slightly more expensive. The sound quality on this RHM speaker is impressive and a good quality karaoke machine with 2 wireless mics is hard to find. The system is extremely user friendly, comes with simple instructions and has provided my family and friends hours of fun! I love how easily transportable it is, so it's not a hassle to bring it anywhere and it holds a substantial charge. So much so, that when I didn't use it for awhile, I forgot what the charger looked like and tried to charge it up not knowing I was using a different charger. I contacted the company who QUICKLY responded and helped me troubleshoot the problem. I realized I must have misplaced/lost the original charger. Though it's my mistake, they are kindly sending me a new charger. Honestly, I don't write reviews very often but the customer service was so outstanding, that I had to share. Great product and next level customer service!
