WinBridge Voice Amplifier with Bluetooth, Portable Speaker and Microphone Set, Wireless Mic Headset Speaker for Teachers, Tour Guide, Public Speaking, Fitness Instructors, Features Mute, 15W WB002

For such a small device, this amplifier is amazing. Light and discrete, you don't feel odd having this on you like some of the bulkier counterparts. Produces good quality sound and loud enough to be used in the classroom setting with ease. With multiple options for wearing it and a wireless headset/ microphone, it's so easy and convenient to use. My preferred way is to have it sit at the front of the room and keep the headset around my neck, keeping me hands free and able to move around. The range is incredible- I tested in a two story building and the amplifier was able to pick up whispered conversation from the opposite side of the office downstairs. Would highly recommend for all teachers, or if you're thinking of getting a new graduate a gift to use in the classroom, this is amazing value for money!

Usei bastante no começo, a bateria durou muitos dias, uns 4 ou 5 para aulas de meio período. Achei as travinhas para conectar a parte que usa na cabeça muito fracas: nas primeiras semanas de uso, uma delas quebrou. Após alguns dias de uso , repentinamente parou de funcionar: os dois ligam, mas o bluetooth não funciona! Já deixei descarregar completamente e recarreguei de novo, pra ver se funciona, mas não funcionou. Não sei o que fazer para solucionar o problema.

Comprado hace ya tiempo y muy muy bien. Igual que el primer día, funciona perfectamente, se oye de lujo. Perfecto para dar clases. Todo Ok!

Además de que es bastante ligero y portátil. Lo llevo para dar clase en la Universidad todos los días.

I bought this to use while leading walking tours near busy San Francisco streets. Most of the other tour guides use the type with a wired headset and I wanted to instead find something wireless. Another reason I chose this one was because the speaker it light weight and I didn't want something heavy hanging on my neck. First couple of times I tried it it seemed odd, I could hear echoing. I had read that the blue tooth mics could have a delay, so I considered returning it for something wired. But I wanted to see if I could change different things (mike position in relation to my mouth, location of the speaker, etc.) to really give it a fair shot. Turns out that I think I had the speaker hanging too high on my chest, and maybe the mike was picking up not only my voice but the voice on the speaker. I lowered the speaker so it now comes just to my pant waist line, I placed the mike directly in front of my mouth and found a medium high volume. Now it works great. Sounds good to my listeners and to me. The only thing I am not crazy about it using the mute function. It doesn't always turn back on automatically when I try to unmute it, so I just leave it on the entire tour, moving it from my mouth if I want to sip water or speak just to one person. With those tweaks in mind I highly recommend.
