SHIDU M800 Voice Amplifier, 18W Portable Bluetooth Speaker, IPX5, Green

The SHIDU M800 pairs an 18W speaker with a wired headset microphone, helping your voice carry while your hands stay free. Use it for lessons, meetings, training, tours, or outdoor activities. Bluetooth and USB connectivity also make it useful for playing audio alongside spoken instruction.

What matters most

The headset microphone lets you speak while moving, demonstrating an activity, or holding materials. Its wired connection is a practical fit for a setup where you want the microphone linked directly to the amplifier. For a class or guided tour, you can address the group without needing to hold a separate microphone.

The M800 also works as a portable speaker. Connect a device through Bluetooth, or play audio using a USB flash drive or TF card, a 3.5 mm AUX input provides another wired option. The amplifier can play music while you speak into the headset, and one-key recording and loop playback support recorded lessons, announcements, or repeated audio. Its rechargeable 4,400mAh battery is designed for portable use, and the display shows the remaining battery level.

The IPX5-rated housing resists splashes and light rain, making the speaker suitable for outdoor instruction and activities where it may encounter water. It is not designed to be submerged. The enclosure is ABS, and the unit measures 4.5 x 3.7 x 1.5 inches and weighs 0.62 kg. Buyers often praise its clear, useful voice amplification and straightforward operation, feedback on battery life, volume control, and Bluetooth varies.

Getting the most from it

For a lesson or presentation, connect the headset, set the amplifier where its speaker can project toward the group, and speak into the microphone while keeping your hands available for notes or demonstrations. When background music or listening material is helpful, pair a device over Bluetooth or use one of the supported media inputs. The volume control lets you adjust the output for the setting.

This is a different approach from carrying a handheld microphone: the headset is intended for hands-free speaking, while the compact speaker combines voice amplification with playback and recording features. Keep the microphone positioned away from the front of the speaker to reduce the chance of feedback. For outdoor use, its splash resistance adds practical protection, while keeping the unit out of standing water and away from submersion.

Who it’s for

The M800 suits teachers, coaches, tour guides, and presenters who want portable voice amplification with a headset rather than a handheld mic. Its multiple audio options also make sense for instructors who use music or recorded material as part of a session. For example, a coach can speak through the wired headset while playing background audio from a phone over Bluetooth, keeping both voice and playback available through the same speaker.

It can also serve people leading outdoor activities who need hands-free speaking and a speaker housing rated to resist splashes. The wired headset is the key choice for buyers who value a direct microphone connection, Bluetooth is available for audio playback, not for a wireless headset.

Final verdict

Choose the SHIDU M800 when your priority is a portable, hands-free way to address a group, with Bluetooth and other playback options ready for lessons, tours, or training sessions. Its wired headset, 18W output, recording and loop-playback functions, and IPX5 splash resistance bring voice projection and practical audio playback together in one compact amplifier.
