    • Why look any further? This amplifier has fantastic sound quality and is so easy to use.
Color: Black
WOW! This amplifier is really really fantastic. The sound quality is off the charts, I had been using a big Sony speaker with a corded microphone and although it was nice sounding in comparison to this sound quality of this amplifier, there’s no comparison. I thought that I would have to try different amplifier. Send them back get a new one, etc. etc. but I don’t have to do that because this is the real deal and I sing a lot and let me tell you if you’re going to buy an amplifier and you want good sound. This is the one I haven’t even thought about the other features and there are a lot but I do highly recommend this amplifier and I’m just an ordinary person. Basically I’m not like being paid to say it’s a beautiful amplifier or anything like that. No, this is this is this is very good amplifier. ... show more

    • Fun amplifier for events, but not a true karaoke machine
Color: Black
I’ve been using this more at home about as much as I expected... which is a lot, mostly just plugging my phone in over Bluetooth and messing around with songs when I feel like it. The sound gets loud fast without sounding like it’s falling apart, and I can actually hear a decent split between vocals and instruments instead of everything turning into a muddy mix. The two microphones connect without any issue and they feel solid in the hand like professional mics. I like having the option to tweak bass and treble instead of being stuck with one flat sound too. It doesn’t feel complicated to switch between Bluetooth and wired inputs, and I’ve run music through it from a laptop and a keyboard just to test it out, which worked fine for me. The thing that I keep coming back to though is that it behaves more like a compact PA speaker than an all-in-one karaoke setup, which is fine for how I’m using it, but it’s worth knowing going in, especially if you prefer an all-in-one system. My older machine had a small and ugly screen, but it was an actual karaoke machine. With this, there’s no lyrics display or built-in karaoke system, so I’m relying on another screen for that part. It’s also got some weight to it, not as lightweight and portable as expected, but not so heavy I can't lift it. While that makes it feel sturdy, it’s not something I’d want to carry around constantly. The microphones run on AA batteries and I wish it had an option to recharge instead, but it works overall. None of this really gets in the way once everything is going though. ... show more

    • Better value than Harman Kardon
Color: Black
I picked up this karaoke machine for our weekend family gatherings because we always end up trying to sing along to music on a tiny portable speaker. Right out of the box the overall quality of this unit really surprised me. It has a very solid construction that feels like it can handle being moved around the patio without any issues. I was a little worried it might be too bulky but the physical size is actually perfect to set up on a side table without taking up all the space for food and drinks. The ease of use is definitely a huge plus because I had the bluetooth connected to my phone and both wireless microphones synced up in just a few minutes without needing to read through a complicated manual. Once we finally got the music playing the actual audio output completely blew everyone away. The raw power coming from the speaker easily fills the entire backyard and the dedicated treble and bass controls let me dial in the perfect sound profile for whatever genre we are listening to. Singing along with the dual microphones has brought so much fun to our weekend barbecues especially when my six year old niece and seven year old nephew take over the stage to perform their favorite songs. The vocal clarity is crisp and there is absolutely no annoying feedback even when they stand right next to the machine. When you consider the professional sound and the fact that it comes with two wireless mics the overall value for money is absolutely outstanding. I highly recommend picking this up if you want to elevate your next outdoor event. ... show more

    • Very well made karaoke machine that also works as a small speaker
Color: Black
This is an impressively nice karaoke machine. The first thing that stood out to me is how well built it feels. It has a solid, quality feel to it, and it seems like more than just a cheap novelty speaker with microphones included. There are a lot of knobs and controls, which I like. You can adjust different aspects of the sound instead of being stuck with one basic setting. It may take a little experimenting to figure out exactly how you want everything set, but the controls make it feel more flexible and more useful. I was also hoping this could double as a small boom box for playing music, and it does work for that. The music playback is good enough for a small room, small gathering, or casual use. I would not expect it to replace a large outdoor party speaker, though. The microphones seem to come through louder than the music playback, so as a regular speaker it is better for smaller areas than big outdoor spaces. As a karaoke machine, though, I think it is excellent. That is clearly what it is designed for, and for that purpose it feels extremely well made. The microphones, controls, and overall build make it feel like a real karaoke setup rather than a toy. Overall, I am very happy with it. It is well built, has a lot of useful sound controls, works well for karaoke, and can also serve as a decent speaker for smaller spaces. ... show more
