Providing both voice amplification and MP3 playback in a handheld, portable package, the MP-25 25W Megaphone with Siren, MP3 Player and Detachable Microphone from Polsen is capable of over 1,500 yards of audible range, making it ideal for use in high-noise areas and large open spaces. Featuring both a handheld microphone with a coiled cable as well as a built-in microphone, the MP-25 can be used in scenarios where you need to face a different direction than the megaphone, as well as one-handed applications.

Thanks to its built-in MP3 player, which can play files from either a USB flash drive or SD memory card, the MP-25 can be used to play music, or pre-recorded messages. Additionally, a 3.5mm auxiliary input allows you to connect a smart phone or MP3 player directly to the MP-25. Whether using the MP3 player or auxiliary input, the megaphone's microphone still functions, allowing you to talk over your music or message as needed.

The MP-25 features sturdy ABS construction, allowing for use both indoors and out, and can be carried with the included shoulder strap. Eight C-size batteries (not included) provide up to 5 hours of use.
