Buyer's Guide

Buying a voice amplifier can ensure you're being heard and that everyone is clearly getting the information they need from you. Amplifiers are also an excellent way to keep your voice and throat from growing irritated and can help make long stretches of speaking less strenuous.

To decide which device is best for you, you need to think about your profession and the environmental setting the voice amplifier will be used in, do you need to use your hands a lot? Will you spend a lot of time outside? Will a wired mic get in the way? The answers to these questions can help in narrowing down the features you need.

For example, for instructors and coaches who spend a lot of time near water, we would strongly suggest number 2, the IPX5 waterproof amplifier because of its rugged features and water resistance. And the added bonus of the device working as a Bluetooth speaker for music can make cleanup after classes seem less tedious. This model is recommended for fitness instructors as well because of its hands-free wireless microphone design.

For interviews and situations where there will be dual speakers, the Winbridge S92 is hands down the best choice, coming with two microphones and the integrated double-emission feature. This would make a great addition to classrooms where guest speakers are often present. The S92 could also be used during seminars and ceremonies.

For professional speakers and performing artists, we suggest the DuaFire and the Zoweetek models because of their sound coverage. These models are ideal for larger spaces and can compete with the noise of outdoor bustling. These devices would also be suitable for large outdoor classes to assure that every student will hear your instructions.

For professors and office settings, the WinBridge Voice Amplifier would be a great choice because of its lightweight design and affordable price (it is the cheapest amplifier on the list) and the lapel microphone. This device would work well for larger meetings where the hearing impaired may be present. The battery lasts for up to six hours on a single charge so you won't have to charge it often.

For those on a budget, the DuaFire and Zoweetek are the best options, they boast similar features and have enough sound coverage to work in larger rooms such as studio spaces. Both devices are under $30.00 and have four-star reviews on Amazon.

Best Pick

The overall best pick is the Winbridge S92, while it is the most expensive model on the list, it also packs the most features and accessories right out of the package. With two microphones, and the headset having a small, easy to place transmitter pack it is probably the most versatile option that will be used again and again. Although it does take several hours to charge, the device allows 6-8 hours of amplification, that is plenty enough time to give several presentations.
