SHIDU Voice Amplifier for Teacher with Portable Microphone and Speaker, 18W Megaphone with Wired Mic Headset, IPX5 Waterproof & Rechargeable Bluetooth Speaker Systems for Tour Guide (NOT Wireless)

I teach Sunday school and used this to work with kids on the playground to play some games. It worked great . The kids and parents to could hear me out well.There is a loud background screeching noise which comes every once in a while suddenly , which u can remove either by adjusting the mic distance from speaker or tweaking the volume. But overall happy with the purchaseI love it that i can use it as a Bluetooth speaker- though the connection is a bit time consuming and an emergency power bank. I just wish the controls were a bit more user friendly.

I been using this voice amplifier and it’s stops me losing my voice during some of my event/production jobs I manage. The sound for the speaker is clear and loud enough to reach everyone in the room without any distortion and witbout me having to yell or lose my voice. It’s extrmely lightweight and easy to wear, so I can move around freely while speaking. The bluetooth feature is awesome because I can also connect it to my phone to use it hands free. The battery life is also pretty good I’ve used it for hours without needing to recharge and for those long days working its definitely a good thing. The thing I like the most is that it is super easy to set up, so I don’t have to mess with complicated settings before I start using it. If you do a lot of presentations or manage people and need to give direction to a lot of people at once, this thing makes a huge difference in getting your voice heard effortlessly!

Powerful, heavier than others due to waterproofing. Very clear and loud. Advertises battery as 4,400 ma, on case shows battery is 1,000 ma. You can watch the battery meter fall even if just on and not “in use”. You can connect via Bluetooth AND the wired mic so that’s a plus. Controls are digital so harder to use and not immediate. To “mute” you need to unplug wired mic. Controls for volume are not marked “+” or “-“ so you need to know which is whichPros: sturdy, loud able to connect two devices and Bluetooth works well with iPhone.

The SHIDU Bluetooth Voice Amplifier arrived properly packaged. I have tested it and it works great, with very good sound quality. It has dust and water protection, which makes handling a bit difficult since the buttons are covered by the protective layer. Aside from that, the sound quality is excellent and the battery performance is also very good.

I have had mine for about a year now. I use it for teaching in the classroom and I appreciate how easily it is to change the volume on it and that it gets loud enough for me to use it in the classroom. It is a little heavier, so I wouldn't recommend using the clip on your waistband unless you have a belt on. It's also really helpful if you're sitting down and can set it on the table if you're reading aloud or standing at a podium. The battery also last for a really long time. I substitute teach, so I'm not working everyday, but I still only have to charge it maybe once a month.The microphone cord sometimes makes a little noise as it's tapping against your clothes or if you bump it while you're talking. The microphone works really well and has a clean sound. It also has good noise canceling and just picks up your voice instead of all the noise around you, whether you're wearing it on your head or around your neck.

he comprado 4 para mi empresa de turismo, han durado funcinando bien un mes, ya que al cumplir este tiempo y poco uso, los altavonces empiezan a hacer un sonido de ruido, he enviado a reparar y me han mostrado como el altazos se ha desprendido, he intentado solucionar pero desafortunadamente es muy dificil conseguir un altavoz de las mismas caracteristicas en miciudad

Super happy with the quality of this speaker! Functions great, easy to connect to, speaker is loud and keeps a great charge. I use it for teaching and room can hear just fine. It’s a good size so it’s comfortable to wear.

Every Bluetooth device should have the option to enable/disable itself. As soon as I turn on the device, the first thing that is heard on the speaker is "Bluetooth is waiting for connections". It's just a matter of time for someone to try to make themselves funny through your device. This device is not a personal voice amplifier, it's a good quality bluetooth speaker.UPDATE: I am changing the rating of my review to neutral due to the attentive customer support I have received during the last week, and also the genuine interest to make your shopping experience pleasant. As for the product, I think it is a robust construction device with good audio quality for its price, in addition to the other features it has. However, I maintain my position that its application as a voice amplifier is compromised by not being able to disable Bluetooth.
