Question: Is there a way to "lock" the trigger button down so you set down the horn and talk or play music through it without squeezing the trigger manually?
Document: Some music will sound fine mono, some won't. I also noticed the delay that is stated in other reviews, so sometimes you'll want to push the talk button and wait a second or two before speaking.I would suggest reading the descriptions of used items carefully before buying.
Its a nice megaphone, real durable, but the only thing I have to say bad about this product is that you have to talk real close to the microphone in order for it to be loud. But if you ignore that, real good purchase. Its real cool that it has the audio jack to connect a device to play music, not the best sounding quality with the music playing because its a megaphone.
Mic detaches from the back of the bullhorn or clips on. Volume control is on the mic and also has a push to talk button. Talk trigger exists on the handle as well. Takes 8 &#34;C&#34; size batteries so buy yourself some rechargables. Tenergy has a great 5000mAh rechargable &#34;C&#34; that I purchased for this. Twice the capacity of an Energizer and at the same price.
Handy and useful if you have a need for it. It isn't as loud as I thought it was going to be, but it sure beats yelling to get your point across. I wouldn't recommend using it for music--as it is capable of doing-- because you have to depress the trigger and hold it in to keep it playing.
This is a fantastic product. This is my third megaphone in 10 years (mostly used for crowd control for 250+ guests at football tailgates). Compared to past products I have owned, the all black color and the MP3 input truly make this product distinct. The only negative is that there is a delay when you press the talk button to when the sound is projected. I have noticed that this is based on when it was last used. Example:1.
product looked used or at least poorly made,after installing new batteries found the trigger mechanism did not work,so i took it apart and found the slide inside the switch had a loose screw on the mount and bent ,so i fixed it then after using it a bit the (siren-off- talk) toggle switch quit working,so i dissassembled it again found the switch had fallen apart,with a corner broken off the circuit board,repaired switch.
I bought this megaphone for airsoft games that I do with my boys. We host about 50 kids at our games and this thing is LOUD. The 8mm jack is nice - I can setup a group of songs and random sound effects on my MP3 player then just to lay this thing out in the field and it will blast music and sound effects I've downloaded off youtube. I've had it for almost 6 months and it's still going on the original set of batteries.
The build quality of the horn itself is pretty solid but the detachable mic and battery compartment durability over time could be a problem. Works great, plenty loud and a great value.
The siren doesn't work and it came without instructions. Needed this for a race Marshall and it was not able to make the siren.
was advertised as new but the scuff marks on the phone indicated that it was a refurb. the trigger has a slight delay and mic feedbacks easily. If I had paid full retail, it would have been returned. Low to mid level. Definitely not professional.
