This wireless microphone device is great for teaching, public speaking and amplifying music or media content, and it also has the ability to play MP3s and record. The battery life lasts for 4-6 hours when fully charged. However, the device voice prompts are all in Mandarin Chinese which is inconvenient for some users. Moreover, there is a persistent hiss that occurs when using the microphone, which can be filtered out by switching mode. All in all, the device is an inexpensive option that is worthwhile to purchase.
