Description
What should I do if the microphone cannot connect to the speaker? If the connection fails, press and hold the + and – buttons on the microphone at the same time until 1d appears on the display. Then restart the speaker to complete the pairing. If still not working, contact our support. Why is the volume low when I connect my phone to the speaker via Bluetooth? If "Reduce Loud Audio" is enabled in Headphone Safety, it may limit your Bluetooth volume. To fix this, go to Settings > Sounds & Haptics > Headphone Safety to adjust or disable the limit. Your speaker will then reach full volume output.

I honestly wasn't expecting this Karaoke PA System to have this good of sound quality that it has. It's big but it has wheels and a pull up handle for taking it out and about the gigs or to parties and it's not really that heavy so transporting it it's pretty easy to do. Like I said in the beginning here the sound quality is much better than I thought it was it's got a nice equal balance of the highs mids and the bass and it has the extra bass thump too. And the sound quality is clear and clean even at higher volumes, so you can turn it up and not lose the that good sound quality. It has record and playback at USB port that TF card slot auxiliary line in as well as two 1/4 inch Jack inputs for two extra microphones or maybe a guitar or keyboard and a microphone I mean the choice and options are there for adding an instrument to it or again extra mics nice to have that option for those options. You have microphone volume control she the master volume control. The two microphones are both pretty solid well may just like the system they connect right away with no interference no static even at longer distances I was about 25 ft and it picked up just fine without any interference like I said or static is that good quality sound that's clean. It comes with a fully functional remote control with batteries as well as the rechargeable batteries for both microphones and so far the batteries have held for quite a while I haven't had to charge them up yet and that's after using it for two or three hours. And the same with the system itself I hadn't had to recharge it yet now I probably will just to get everything back on a full charge but it has held up quite a long time in my opinion without having to charge it yet. They connected via Bluetooth to my Android smartphone with no problems and again when I play music back the music was just as clear and clean even through the Bluetooth. This is a nice system it's got a lot of options to it a lot of fun stuff it's easy to carry around with you if you have to take it it's on wheels it's got the pull-out handle it's got a very cool looking light display that seems to sync up with the music. In my opinion it's well worth the value you're getting it a very good quality product for not a very big price I would definitely recommend it especially if someone's on a budget but doesn't want to lose any quality of the sound or product.

This speaker set made a great first impression. Unfortunately, the LED display on my unit does not work, and I believe it arrived with a factory defect. Even so, I was able to navigate through the different modes without much trouble, as switching between Bluetooth, FM, USB, and other inputs was smooth and intuitive despite not being able to see the display. Voice commands and guidance is available so I had knowledge to which functions I'm getting to. In addition, you have an included remote control (batteries are included) which should make things easy as well. Where this speaker really shines is in its sound quality. The dual 8 inch woofers deliver deep, punchy bass with plenty of volume, making it more than capable of filling a backyard gathering or family party. Music sounds full and dynamic, and the overall output exceeded my expectations for a speaker in this price range. The two included wireless microphones were another pleasant surprise. They have a solid, professional feel with a good amount of weight, rather than feeling like inexpensive plastic toys. The rechargeable batteries on the microphones where a pleasant surprise as I have a charger for that type of batteries and actually carry spares, so won't need to stop having fun while I change the batteries for one that is charging. Bluetooth pairing with my phone was nearly instantaneous, and the connection remained stable throughout my testing. Portability is another strong point. The built in wheels and pull handle make it easy to move around, and it rolls smoothly without much effort. While the product is marketed for outdoor use, I couldn't find any IPX rating for water or dust resistance, so I would still be careful to keep it away from rain or wet conditions. If not for the non functioning display, this would easily earn five stars from me. Despite that issue, the excellent sound quality, solid microphones, easy connectivity, and overall value make this a very impressive karaoke system for the price.

This karaoke machine is going to be a little difficult to review, specifically because we have experience with a competing brand. Let me start with the challenge, and then move on to the pros, which are many. The biggest challenge with this is the lack of the screen and music source. At this price point, comparable models have an integrated touch screen that directly connects to either a paid service or services you are probably paying for if you are shopping here, such as Amazon music. That means you can simply pull the machine out, turn it on, and dial up your playlist, including the display for karaoke lyrics, directly on the device. With this device, it is up to you to figure out how you want to get those songs playing. You could do Bluetooth or you could do a audio connection direct to the speaker, but that does take additional hardware and setup from you. Where this excels at is the opposite end, the speaker system itself. As you can see in this video I am playing a track with both strong highs, mids, and bass, and the speaker does a really good job across the spectrum. The included mics are also really nice and heavy, and feel premium. The ridiculously large mic and volume buttons make it very easy to adjust your settings, and the turnable knobs on the top for trouble bass and echo give you a lot of fun options that you would use in a real karaoke machine. What I most appreciate about this is the luggage style carrying handle, enabling you to roll this in addition to pick it up and carry it like you normally would. I have yet to run this thing to zero battery, so it lasts for hours, although I concede when running this for a long session I am plugging in a 10,000 milliamp hour USB pack with it just to make sure it doesn't die. So how to rate this? As a karaoke microphone and speaker system, this is easily five stars. I'm not wild about the fact that you own what I think is probably the most complicated part, figuring out how to get a screen and lyrics to play what you want, but as long as you know that going into this I can recommend this, and I'm able to give it five stars.

I'm really happy with this karaoke machine. It arrived in perfect condition with no issues. It is actually double boxed to protect it. It's very well made from a really sturdy premium plastic. Even though it's on the larger size, it's easy to move around with a large built-in handle and nice wheels. It's very easy to set up and operate. Pretty much any type of audio source will work with this. It has a well-rounded sound quality, and I credit that to the 8" speakers. It gives enough bass that dance and rap style music sound good. It gets nice and loud with no distortion when played at high volume. The led light effects are neat, and there are many options for what kind of light show you want. The microphones are full size and have a quality feel to them, plus they have a good range and clear output. The back of the unit has two holsters to keep the microphones I when not in use. It has a nice battery life and has lasted me several hours many times. I do keep it plugged in while using it, which does give it a trickle of power. It also includes a remote that is a nice addition and it has a good range. This will get the party started and is a nice value for what you get.

This karaoke machine is so fun and easy to use right out of the box. The mics are cordless and there are holding straps on the back of the machine to keep them secure so they do not get lost when not in use. I love that the batteries in the cordless mics recharge with a type c cable, which is super convenient. The unit itself is also cordless and requires no plug in cords to operate, so I can roll it anywhere with the wheels and pull handle. I paired the unit to my laptop and was able to sing karaoke off YouTube in my living room within minutes of opening the box. I would love to get the neighbors together for a karaoke night, but will need to purchase a bigger monitor than what I have on my laptop. For now the setup works great, and the 80W power with dual 8 inch woofers gives plenty of deep bass and volume for the house and outside (luckily we dont have close neighbors lol.) If I could give this unit more than 5 stars I would. It is such a joy to sing on my own and with my family. This instantly created something fun to do together as a family. I am looking forward to many more hours of singing!

I used this for a family gathering and was impressed by how much sound it produced. The included microphones connected easily and worked well for singing and announcements. The wheels and pull handle make it much easier to move than expected for a speaker of this size. I liked the deep bass and the LED lights because they added to the party atmosphere. Bluetooth pairing was quick and remained stable throughout use. The controls are easy to understand and adjusting the volume and sound settings was straightforward. It is fairly large, so it does require some storage space when not in use. For parties, outdoor events, and family entertainment, it feels like a good value overall. I recommend this product.

I was pleasantly surprised by this karaoke machine. It was packaged well, set up in just a few minutes, and paired with my phone over Bluetooth without any hassle. The sound is loud and clear with good bass, making it great for family gatherings, parties, or even just listening to music around the house. The included wireless microphones connected quickly and worked well with no noticeable lag. I also like that the speaker is portable with a built in handle so it’s easy to move from room to room or take outside. The controls are easy to understand and there are enough inputs and playback options to make it versatile. Battery life has been solid so far and the overall build quality feels better than I expected for this price range. Overall, this has been a fun addition to our home. If you’re looking for a portable karaoke machine that doubles as a Bluetooth speaker, this one is definitely worth considering.

So Awesome. We have several Green Keeper models like this, but it's the biggest and loudest one, yet. We hook them up around the room for surround sound, or take a couple outside with laser lights, and it's a blast. And we let the kids use the smaller ones so they're not left out. Good build quality, great sound. Love the trolley wheels and handle. This one's a Win.
