As a vocational training lecturer, I can also be regarded as an educator. The megaphone I usually use for students in class is Sony Ericsson's SH22 Bee Microphone, a domestic brand product. I wear it every class, which saves me a lot of energy.
I use a wireless model, and the speaker can be placed in the middle of the classroom, so that students can hear more clearly and save their voices. I will copy some audio materials to TF card or USB flash drive in advance, and insert them directly into SH22 to play in class. You can use this product to listen to music on the radio or USB flash drive when you are resting and closing your eyes.
This portable and compact speaker can really meet my needs and help me solve many teaching difficulties.

Which brand of speaker is good?
It depends on the kind of speaker used. Bee type, as mentioned above, will do. If you want the wireless type, you can use JTS brand, which was established in 1982 in Taiwan Province Province and has long-term experience in wireless microphone system. Similar Taiwan Province Mi Bao is also a professional wireless speaker, which was established in 1995. These manufacturing costs are high and expensive, and they are generally purchased by enterprises or government units. Compared with Mi Bao's public relations, JTS recommended by singer G.E.M. is better, but JTS is still better than Mi Bao in sound quality, especially the design on the microphone core is very interesting. The hand-held microphone with larger amplifier usually seen in the market is still quite large. The hand-held microphone of WA-35 is small and compact, with one battery and high sound quality.
