DGTenk Voice Amplifier for Teachers Portable Microphone and Speaker

About this product

• HIGH-FIDELITY VOICE AMPLIFIER FOR TEACHERS — Equipped with a 3-inch full-range speaker, this portable voice amplifier delivers clear, balanced voice coverage for classrooms with up to 200 students. Built-in anti-feedback design helps minimize howling during normal use; position the speaker away from the microphone for the cleanest sound in classrooms, training rooms, and small-group settings.
• LONG-LASTING RECHARGEABLE BATTERY & USB-C CHARGING — The built-in 2200mAh battery delivers up to 12 hours of wired-mic use on one charge, covering a full school day or a full day of touring. It charges via standard USB-C at normal speed; a full charge takes about 4 hours.
• STABLE WIRED MIC AMPLIFIER FOR LONG-TERM DAILY USE — Unlike wireless voice amplifier for teachers troubled by pairing failure and disconnection, this unit is easy to set up: power on and connect the wired headset mic. The wired link ensures stable voice pickup without repeated pairing or mic charging. Analog dials support smooth, precise adjustment for reliable teaching.
• VERSATILE PLAYBACK MICROPHONE AND SPEAKER SET — Use the 3.5mm AUX input, USB flash drive, or TF card slot for background music, recorded drills, or event audio. Single-track repeat and playlist loop make it easy to run practice sessions, break music, or guided-tour narration hands-free.
• ULTRA-PORTABLE WEARABLE DESIGN FOR ALL SCENES — Weighing less than a pound and measuring 5.32 x 2.09 x 4.32 inches, this wearable microphone and speaker clips to your belt, hangs from a lanyard, or fits in your hand. The lightweight headset mic stays secure through hours of teaching, touring, or training.
• HANDS-FREE WIRED HEADSET MICROPHONE FOR CLASSROOM — The adjustable wired headset microphone frees your hands for writing on the board, demonstrating materials, or guiding a tour. Different from wireless voice amplifier models, the fixed wired connection means no dropouts and no mic battery to charge—just plug in and start teaching.
• PORTABLE VOICE AMPLIFIER WITH MULTIPLE MODES — Switch between personal voice amplifier and local audio playback to support lessons, fitness classes, or outdoor events. This mini voice amplifier supports TF card, USB drive, and AUX inputs delivering music, recorded instructions, or tour commentary straight from the device—no paired phone needed.
• PROFESSIONAL SPEECH-FOCUSED SOUND CONTROL — Designed exclusively for human voice amplification with independent microphone volume and Echo knobs let you shape your voice for the room. Keep Echo low for natural classroom speech; in smaller spaces, turn Echo down or off to reduce feedback. Analog controls adjust in one motion—no menus to navigate.
