100-Watt Square Megaphone Bullhorn, Lightweight and Portable Loudspeaker Horn with Aux (3.5mm) Input for MP3/Music, Automatic Siren, Whistle, MIC/Talk (Black), 1500 Square Yards Projection Range

Feels a little cheap. Works pretty good and loud, no cut outs with shaking the horn or anything with 9V but with battery pack shaking can affect sound quality.

Coming to a sports game or protest near you, this Pyle 100-Watt Megaphone means business. If you need to be heard, this bullhorn delivers. The sound projection is impressive, easily cutting through noise across a wide area. Whether you're rallying a crowd, directing traffic, or hyping up a team, it gets the job done. It’s lightweight and portable, which makes it easy to carry around for long events. The built-in siren and whistle functions are great for grabbing attention fast, and the MIC/Talk mode is clear and powerful. Bonus points for the AUX input—plug in your phone and play music or pre-recorded messages for even more versatility.

This megaphone functions well and has lots of options. Lower rating because some of the buttons are difficult to use, especially the on/off switch. There is also a very loud and annoying announcement every time you turn the device on.

I'm a very techy person and this thing is incredibly confusing. The battery pack supplied seemingly has no way to work with the unit, despite them coming together in the package. Half the reason I wanted to buy this thing was because I didn't need to buy batteries to put in it, and it was still supposed to be very loud. Right now I dont even see the point of adding the lithium ion battery as there are multiple reports of this not working at all for this unit, and every video on youtube doesn't even touch it, or they have a different battery pack with a different cable supplied. I'll buy the batteries and put them in, but I feel like I should have a pretty hefty discount on this thing. The parts are cheap, it feels very finnicky and loose and despite trying to figure it out for hours, I still haven't even been able to get to turn on with the provided parts. Despite the listing saying it comes with a rechargeable battery. What the hell is this battery even for?

Didn’t work. Battery pack that came with it didn’t work. Had to order separate batteries and it still wouldn’t turn on.
