Are you looking for the best children's microphone?

If so, you may have noticed that there are plenty of options available, which means it can be difficult to find the one that will give your child the most pleasure.

I've written about it before the best toy microphones for kids, but that was more of a general article.

Today I want to talk about the best variants with a speaker in it, because many of you have asked about them too.

That's why we've researched the best microphones for kids and laid out all the details in an informative review just below.

My favorite is this Technaxx BT-X31 which offers a lot of freedom. It's not too expensive but the sound quality is still pretty good. The real power is in the freedom to use any app you want for a fun game of karaoke.

An important thing to consider is whether a more realistic microphone is appropriate for your child, or one that is more of a toy microphone.

If you're still struggling to make up your mind after reading our guide, you can find a Buyer's Guide section at the end to help you learn more about finding the perfect toy for your child.

Best Kids Microphone with Speaker: Technaxx BT-X31

The MusicMan BT-X31 is connected via Bluetooth to its stereo speakers and the 3-watt amplifier to the iPhone, iPad or Mac, optionally a music player can also be connected via Aux or a FAT32 formatted UBS stick with sing-along music in MP3 and WAV formats.

Technaxx BT-X31 microphone with speaker

Five controls are available: one combines the volume of the music source and the vocals, two are responsible for bass and treble, but really only there because we hardly notice a difference when we press the buttons.

Another adds a slightly awful echo effect to your own voice, the latter being ultimately responsible for the overall volume.

The controls look like on / off switches, but can in fact be moved continuously.

But only more than two centimeters, so they are not really fine adjustable.

The Bluetooth pairing is fast and uncomplicated. The sound is not what you get from your Harman Kardon and can be a bit “tinny”, but very good in relation to the price and all the features.

The gold-colored microphone has a battery of 2000 mAh ready, which is sufficient for 3,5 to 6 hours depending on the volume.

It is a pity that there is no app for the karaoke microphone.

This is exactly where the manufacturer could have made a difference and recommended at least one for iOS or Android or macOS or Windows or maybe even released its own.

Then just browse the app stores and YouTube to find resources for karaoke fun.

Technaxx names this as a great advantage, so that you are not dependent on a specific karaoke app but can use whatever you want, which means great freedom at any singing party.

Mi-Mic is a karaoke microphone with built-in speaker and Bluetooth functionality.

It is equipped with an SD card reader, USB rechargeable battery and charger.

With the Bluetooth function, you can connect the Mi-Mic to any paired device (iPhone, Android phone or tablet) so that you can play music from the device through the microphone speaker while singing into it.

The built-in speaker then broadcasts both the music and vocals, creating a more complete karaoke experience.

This allows you to play any song directly from your device. You can put on your favorite tune and then sing along.

While doing this you can sing 'karaoke style' and the Mi-Mic will add your voice to the song being played and you will hear a mix of the original song, your voice plus the addition of extras added from the Mi-Mic.

You can get extra creative by adding an echo effect and distortions to your vocals!

Mi-Mic also comes with 7 color beat matching LED lights that blink to the beat of the music.

You can choose a static color or changing colors that light up while singing.

The mic also features FF / RW / Pause / Play buttons and volume knobs so you can make the song as loud or quiet as needed.

Turn up full volume to use it as a conventional Bluetooth speaker (you may not have separate bluetooth speaker more needed for the nursery) or lower the volume and let your best Adele impression take center stage.

This microphone is charged via USB and the high capacity rechargeable battery lasts up to four hours on a single charge!

It has a range of ten meters and also takes TF card. This makes it perfect for a kids karaoke party.

The Mi-Mic is suitable for children of 6 years and older, but children as young as 3 years old often enjoy playing with it too, especially if they see an older sibling with it.

I've tried it too and I have to say it's really fun! It's great that you can sing your favorite songs and listen to them at the same time.

The sound effects also add to the fun! As you can see, this microphone is perfect for the whole family!
