voice amps for teachers

You’ve probably been there.

You’ve gotten through a long week of teaching, and your voice has just about had it. But you know your students depend on you – and your voice – to help them learn and grow.

That’s where a portable voice amplifier comes in. For teachers (and their vocal cords), it can be a real lifesaver. Voice problems are a real occupational hazard.

The best voice amplifiers for teachers help alleviate vocal issues by clearly amplifying even the softest voice without straining a vocal cord. Using one will allow your students to learn – and your body will thank you.

We’ve researched and compiled a list of the top vocal amplifiers for teachers. Our editor’s choice is the WinBridge WB001 Portable Voice Amplifier With Headset Microphone because overall, it meets all the requirements. The voice amplifier features a long-life rechargeable battery with up to eight hours playing music and 10 hours for teaching, excellent audio quality, a portable mic with an adjustable gooseneck headset, and made from durable materials.

The list features a wireless voice amplifier with mic, Bluetooth speaker with built-in microphone system, systems functioning as MP3 players using audio input, Micro SD card, or USB port, and waterproof systems for beaches, pools, or the shower. Some amplifiers with lower power output work perfectly in standard classrooms or online teaching, while others are ideal for outdoor use for coaching or field trips.

What Makes A Great Teaching Microphone And Voice Amplifier For Teachers 

A great portable voice amplifier microphone system provides excellent sound quality over a distance that won’t strain a teacher’s vocal cords. The best voice amplification devices have these features and characteristics in common.

The battery life of a portable microphone and voice amplifier varies from 3 to 15 hours of power output. Sometimes a battery that lasts 3-5 hours is sufficient for a classroom microphone. Still, a strong battery with long battery life is more effective and convenient for long teaching sessions and outdoor use covering a large area. Teachers can charge or change batteries between lectures but using the system outdoors requires 10 to 15 hours of battery life. If the batteries need recharging when fully drained, make sure you choose a system with good battery life. 

Volume level and additional features also affect the battery life; at full volume, the charged battery won’t last nearly as long as at a lower volume. Rechargeable batteries are environment-friendly and could save you money; you don’t have to replace batteries often and can charge the batteries at your convenience.  

Make sure the system is loud enough for your purpose. Teachers using a teaching microphone and voice amplifiers in the classroom won’t need nearly as much volume as coaches, field trips, gym instructors, and other outdoor events. 

Loudness varies from built-in 5W or 10W speakers that will help save a teacher’s voice but won’t be as effective in a noisy crowd or outdoors. Powerful speakers can range from 18 W up to 50W to cover larger classrooms and outdoor areas. The manufacturer may indicate the sound coverage on the package; the sound range covers a larger space in a quiet classroom than outside or in a noisy gym. 

A portable microphone and voice amplifier are lightweight, compact in design, wireless, and clipped to clothing or worn around the neck. Portability is essential for field trips, coaches, outdoors, and teachers who move around the classroom while teaching. 

A wired system may limit freedom of movement, be sufficient for standing still when teaching and cover a larger space due to better connectivity than a wireless mic. Consider a wireless portable voice amplifier and wireless microphone with a headset to maximize freedom of movement. You don’t need to carry the wireless system on your body or have tangled wires. Be mindful of quality and connection reliability; a wireless one is convenient, but you don’t want the system to cut out during a session. 

Additional features could make operating the system more intricate. For example, connecting a wired microphone to the voice amplifier could be easier than the connectivity of a wireless system. Playing music in the background, connecting the device to an MP3 player, and using SD cards and flash drives may complicate user-friendliness. Outdoor use may require a waterproof system to protect against damage from rain or snow. 

The headset and microphone should be comfortable to wear and be durable and long-lasting. Check the sound quality, minimum feedback, and no noises from the headset or microphone. The mic should be easily adjustable for maximum effect.

As many teachers began wearing one when wearing a mask, the importance of a sensitive microphone has increased. A gooseneck headset design will adjust the mic close to the teacher’s mouth – even when using a facemask. 

A general guide is to choose the amplifier’s power output according to the number of students in the classroom, teaching scenarios, and style. The 5-10W output power should be sufficient for 30-80 students like kindergarten classes and 10-18W for 80-120 students. Outdoor teaching and large classrooms will need 20W and up.

Most voice amplifiers include practical and cool accessories. The essential accessories are a waistband or detachable lanyard to attach the voice amplifier to your body; the most popular is hanging it around the neck, waist, or clipped to a belt. A carrying bag, USB cable, Bluetooth features, and a built-in FM radio are other accessories to consider.
