K380F Wireless Microphone Karaoke Microphone Wireless Mic with Bluetooth Receiver Rechargeable Professional - UHF Dynamic FM Cordless Microphone For Singing Karaoke Speech(Elegant Gray)

This mic was easy to use and sounded professional. I just plugged it into my Karaoke machine instead of the wired mic that came with it. It worked straight away without any issues. Just a couple batteries and I was no longer tied to the Karaoke machine. It feels and looks professional, a great addition to Karaoke night!

My wife was super excited to use this right after opening it on Christmas morning. I tried figuring it and lone behold, there was no “18650 Li Rechargeable Battery” in the Bluetooth transmitter or in the packaging. I researched it, and it’s going to be another $20 out of pocket. The extra cash doesn’t bother me as much of the convenience of wanting to use it right away. And this is a failure on the seller for selling this without clearly annotating it in the description/title that it is not ready for immediate use or does not come with all the pieces and parts required to operate it.

Super fun mic for family karaoke at home. Easy to setup and use. The sound is nice and crisp. I had pre-purchased the 18650 battery (for the receiver) so I could use right away when it was delivered The description clearly states that it did not come with that special battery. We use my son's guitar amp for the speaker. Looks and feels like a pro microphone, sure beats the old one we were using.

I bought this product recently and used it in 2 occasions. Everything worked well as expected. I used it during a journey in a bus and also in a car for singing. I could easily connect my android mobile phone to provide background music while the mic was used for vocals. Some of the issues that I noticed which made my mind to give it a 4 star rating rather than a 5 star. There is no charging or battery level indicator in the receiver. It is difficult to determine whether the unit is being charged or not. However, in the 2 occasions that I used the unit so far, the usage time was great since I could use it about 4-5 hours with one charge. When the unit is connected to a FM receiver, sometimes depending on the strength of other signals there could be lot of distortions or noise. In my case direct connection via AUX input gave the best results. It is good if the same receiver comes with 2 separate mics which probably would be what I am looking next.

This mic worked very well until the day it just didn't work anymore. I had to be plugged into the aux port to use it with my car speakers. After a couple months of maybe 15 hrs of sing time it failed and I tried to connect it via FM but the stations offered (only 3) were either in use or even numbered (107.8) which I'm not able to tune my digital radio to. I unsuccessfully attempted to contact the manufacturer to troubleshoot the problem but wasn't able to locate any information on them. Amazon came through for me though and gave me a full refund

I am looking for a good microphone for a long time. this one is very good. I invent my friend come to my home for singing, they all asked me where I bought this microphone. I already used it for almost one month, it works well!

Use it as a back up microphone, it need 2 AA battery for the mic and one 3.7V battery for receiver. test it for several hours, the sound is clear, high and lows sound perfect, and the range is pretty good. it is a good buy!

The media could not be loaded. I’m an engineer, but I will keep it simple. The connection and instructions were simple and straightforward - anyone can do this. However it came with some issues:1. The receiver wouldn’t run on battery power, only plugged in. Note: make sure you have a fully charged and healthy 18650 battery on hand, none supplied. Also 2 AA for the mic.2. There was an echo/delay. Switching channels did solve this problem once, but never again. See and listen to attached video.3. There is no volume control. Not a mistake by the manufacturer, but I didn’t notice and you might not have either.It played the BT music fine from my iPhone, but due to the delay it was impossible to sing along.12/19/2018 update: the manufacturer stated that the delay was due to it being plugged into the UE Megaboom bluetooth speaker. Ultimately I found a fantastic mic that passed the speaker test, but doesn't have the dual RF that this one does.
