  • Works awesome....so far
Color: K666-Gray mic
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. ... show more

  • Amazing karaoke speaker
Color: K666
I bought this strictly to be a karaoke machine with friends. I expected the sound to be subpar, and only good for fun. My jaw literally dropped though the first time I played a song to test out the Bluetooth connection. I have some very high end speakers and studio monitors that I use as an editor, and this thing blew 99% of modern speakers I’ve heard, owned and used out of the water! The bass is so rich and deep and you can feel the vibrations! The highs are good too, though the mids get a bit muddled in certain types of songs. This isn’t anything most would notice, and the mids are still better than a different $400 speaker I have. The only speakers that have better mids are my studio monitors and all of my highest end over the ear headphones. It’s worth it for the bass though, and even audiophiles will be impressed! So far, the 2 mics work great straight out of the box. They make my mediocre voice sound decent, and I’m not embarrassed to belt out high notes like usual! I’ve connected it to my tv through Bluetooth to try too. The delay is quite significant, so definitely recommend the optical connection instead of Bluetooth for this reason. But it’s fine for YouTube karaoke to just use Bluetooth because the delay makes it easier to follow along with the words actually. I do hate the power button and auto power off. It seems to power off way too quickly and there’s no options to change it. Tge mics can’t turn the power on and off on the machine, so you have to manually hold the power button down for 5 secs on the top of the speaker which is annoying if you’re already situated on the couch ready to binge Netflix. But this is obviously a very minor inconvenience that only tech spoiled humans in 2022 could ever complain about. Also, The mics auto power off every 20-30 min too, even if you’re constantly pushing buttons. I have to turn the mics on 6-7 times just to get through Hamilton haha. So it’s kind of annoying and a buzz kill with friends singing ridiculously to Hamilton and then all of a sudden their mic cuts out in the best moments… Still, for the price, you are getting an amazing home karaoke system that doubles as an amazing Bluetooth speaker! 100% worth every penny! ... show more

  • Nice System overall compared to the Ikarao X1
Color: K666-Gray mic
I have spent the last month comparing karaoke systems online and in person. This unit is much smaller and lighter and quieter than the original Ikarao X1 that I purchased, but I kept this one and returned the other. I really loved the loud speaker, ability to download music offline and computer screen of the X1, but the microphones had way too much reverb (even when turned to zero) and I couldn't get all the apps working right. If I ever need an extremely loud boombox or portable way to watch movies or do karaoke I will get that one again! The RHM K666 has enough volume to fill my living room, has nice microphone effects and is very portable. I can lift it with one hand and it is not at all heavy. The Ikarao was super heavy! This unit works as a speaker with microphones that you can connect with bluetooth to your phone, or can just be used as a speaker for the mics. I am currently using it only for the microphones and having the KaraFun karaoke app on my tv with the backing music coming out of my soundbar. It works well and I don't have to worry about the music coming out of this little unit...which would give a much thinner sound. The one very annoying thing about this unit is the battery saving feature on the microphones. They shut off automatically, sometimes in the middle of a performance! I have learned to deal with it, but I think it should only turn off when not in use for the timed amount. Whatever, easy enough to turn back on and if I have a party I will warn the singers to turn off the mic when they are not singing...so the mic will be reset each time it gets turned on. The VE feature does lower the volume of vocals on Spotify so you can sing karaoke style, but it isn't great. Using a karaoke app is much better because you can turn off the vocals completely. I was hoping this feature would work better and it is actually the reason I purchased this unit. However, I really like the lightweight feel of this unit and the microphone features available. I have been singing every day and I really like the improvements I am hearing since I purchased this. ... show more

  • Best portable karaoke machine ever
Color: K666-Pink
My coworker bought this and then me and another one bought it after we tried it at work. The pink color is very pretty and the sounds is perfect . It’s very loud and the sound system is way better than a $800 karaoke home set that i bought before. Very impressive . I would recommend that. And the black color is very pretty too. My friend got it. Matte finish look very expensive and high quality ... show more
