I like to host karaoke nights at my home which I run through my PC attached to our living room TV and AVR, and I use YouTube for the songs. Traditionally, I would plug a microphone into the PC; however, this causes a distracting audio delay, so I went searching for better solutions. I tested three solutions: this system which plugs right into my existing setup, a big stand alone karaoke speaker, and an Ikarao system that I jerry-rigged to work basically the same as this Rybozen. I then tested all three both by recording myself tapping the microphone of each system to objectively measure the delay and in actual use of singing karaoke.I am very pleased that this Rybozen came out on top in every possible way. In my initial set-up, I plugged my PC into HDMI in and ran HDMI out to my receiver where my PC would normally be plugged into. Right out of the box with that set-up, the delay was significantly improved, and in my experimenting, was the least delay of all my options including the designated karaoke machine with its own speaker. I further tweaked it by running the aux cables into the receiver for the audio (I'm using a Denon AVR that supports a separate Audio In for all inputs, you have to tweak the AVR settings to instruct it to override the HDMI audio signal), and that made the delay almost non-existent.Even before my testing, this was my favorite. It was the simplest option easily plugging right into my existing setup. It is also significantly cheaper than other karaoke solutions. I love the simplicity of the five dials to cover Music volume, Mic volume, Echo, and Treble making it super simple to adjust these on the fly as people are singing.In actual use, the microphones were also my favorite of the three. They come with optional foam covers which help reduce the plosives, and overall felt the most like a real microphone (the Ikarao comes with these stick microphones that feel like you're holding a baton).Overall, if you're looking for something portal, or you don't already have a home setup where you just need to plug in some wireless mics, you may want to go in the direction of an Ikarao (which came in second in our ranking). But if you're trying to run karaoke through a receiver and basically use your own AV equipment, this Rybozen is a no-brainer. Nothing else comes close to it.

I play the Native American style flute, and I perform concerts from time to time using a lot of backing tracks that are stored on my phone. My previous setup was to plug my wired microphone into my speaker, and then use bluetooth to send the backing tracks from my phone into the same speaker. The problem with this was that my backing tracks all had different volume levels, and I would have to adjust the volume on my phone (which is on a tripod next to me when I perform). I couldn't have someone adjust the volume on the speaker, because that would adjust the volume of my flute playing into the wired mic as well as the volume on the backing track. So ... I was looking for an audio mixer that would have separate volume controls for my wired microphone and for my backing tracks. Most of the audio mixers and karaoke machines I looked at had only a master volume control that would simultaneously adjust mic volume and backing track volume -- so I was very happy when I found this product.Here's my setup now with this audio mixer. Because the mixer has bluetooth, I connect my phone to the audio mixer instead of directly to my speaker. Then I use an aux cable to connect the "aux out" on the mixer to the "aux in" on my speaker. That takes care of the backing tracks, and I can have another person sit by the audio mixer to adjust the big "Music" volume dial as needed for the different backing tracks. For my flute playing, I connect my wired microphone directly into one of the two microphone jacks on the front of the audio mixer. I set the volume dial for that microphone at a given level and leave it there for the entire concert, since I don't need volume adjustments for my flute playing. I also set the "echo" dial at a certain level for my flute playing into the wired microphone, but the echo has to be turned all the way down when I talk into one of the hand-held microphones that comes with this audio mixer. I do wish there were separate echo dials for the wired microphone and the hand-held microphone!! (NOTE: If the wired microphone is plugged into the "mic 2" jack on the front of the mixer, then you have to use the blue hand-held microphone that connects with the "mic 1" volume dial.)I would have been happy to just find an audio mixer that had separate volume controls for my backing tracks and my flute playing, but the addition of the hand-held microphones is a plus for me. (One mic would have been enough for my needs.) I do some talking between the songs I play, and my wired microphone is set at a lower height than my face because that's where the flute's sound hole is. So in the past, I had to bend down to speak into the wired microphone. Now I can just grab the hand-held mike when I talk, and remain upright! The volume for the hand-held mic can be controlled separately from the volume for the wired mic, and the volume can stay at a given level thoughout the concert.There are two things that would make this product even better. First, as I mentioned earlier, I wish there were separate "echo" dials for mic 1 and mic 2, since I use one mic for flute playing and the other for talking. Secondly, it would be really nice if the big "Music" volume dial had numbers written around the outside so that you could establish a specific numeric volume level for each backing track in advance, and have that written down on a sheet for the person who is running the audio mixer.Overall, this is a great product for my purposes. Even though it was kind of pricey at $100, I'm glad I bought it.

This thing feels super cheap, but that’s OK as long as it works as advertised. This did not for me. CEC over HDMI did not work for me despite a user Q&A saying that CEC is supported. Not a deal breaker since it would only be used for Karaoke occasionally but still annoying. The biggest problem is that most of the time, the audio did not work at all. Powering the unit off and back on would occasionally get it to work but not most of the time. In the end, this thing is just a piece of junk and was returned. Don’t waste your money.

Good value and good for decent home karaoke entertainment. Use couple times and so far so good. My set up is simple, utilizing the Bluetooth functionality mostly:- Firetv (hdmi) -> tv (hdmi) for video- Firetv (Bluetooth/transmitting) -> this mixer (Bluetooth/receiving) for audio, pairing is very simple from Fire TV- This mixer (aux) -> klipsch “the fives” powered speaker (aux)Pros: small and sleek. I am not an audiophile but do have some standard when it comes to audio, so would say it provides reasonable audio quality for both music and vocal. You will need to adjust and balance the music vs vocal volume control for the best outcome. I only use Bluetooth vs aux so far and it works flawlessly, didn’t test hdmi. The tone control does “tone” and “sharpen” your vocal but also makes your voice “thin” and not real but that’s okay and expected for average home karaoke. Did not notice any lag as someone mentioned here.Cons: Not really notice anything big, except some hum, echo feedback when someone sings with a low voice. The output jack and aux cable don’t look like in good quality and a bit loose
