MyMealivos Bluetooth Megaphone with Siren Bullhorn 50 Watt Bullhorn Speaker with Detachable Microphone, Portable Lightweight Strap & 3.5mm Aux Input

This thing is Awesome FUN!!!

We run carnival rides. We bought two of these for one of our rides.One of them was used for loud announcements at the top of a tower, either using the playback (which saves the recording even if batteries are removed. A+) or the microphone, and the other was on loop giving the safety rules at the ride entrance using the playback feature.They were unstoppable, and the rechargeable batteries lasted for 3 solid days of hard intermittent use.I'm extremely impressed

My 16 yr old son uses this for street preaching, telling people about the good news of the Lord Jesus Christ! It is excellent and has gone beyond our expectations! Its loud and clear and has many nice features on it as well as being lightweight and we are very pleased with it. thank you

A little on heavy side but works great

Purchased this for “safety” purposes at work and has been working swell so far.

Has a chargeable battery. Great and loud! Perfect for protests. Free Palestine!!

I used this all summer while lifeguarding. It was not only practical but a lot of fun. Easy to play music through with a simple adapter. I would often ”announce” for the kids as they prepared to dive.

The battery has a single USB connector that is used for both charging (at 5v) and for speaking (at 12v). There is a switch that must be set to either "5v charge" or "12v use". If you forget to set the switch when charging, the charging circuit will immediately be destroyed. This product should eliminate that switch and provide a separate connector (not USB) for 12v output to the megaphone. In spite of being determined to always set the switch correctly, I destroyed my unit at the end of only the second day of use.Other defects: (1) The 3.5 microphone jack didn't work with my (stereo) microphone. I couldn't get any of the stuff on that panel to work. (2) Only a one page instruction sheet is provided, and it is totally inadequate and gives no warning about what will happen if you set the switch wrong. (3) The stitching on the shoulder strap is totally inadequate; it will break at the first good impact or tug. (4) The microphone wire is too short for comfortable use.This is the same basic product as the Uzi, differing only in labeling, the (nonworking) side panel, and the support for a rechargeable lithium battery that is obviously a retrofit to a product designed at least 8 years ago. (I bought an Uzi in 2010.)
