SHIDU Voice Amplifier Teachers with UHF Wireless Microphone Headset, Portable PA System Speaker 10W 1800mAh Rechargeable for Multiple Locations Such as Classroom, Meetings, Promotions and Outdoors

The SHIDU S611 wireless voice amplifier is not a professional singing machine but can amplify the voice for singing. It is wireless with a good volume and a UHF system that makes it secure from unwanted access. However, it has a low volume, a short battery life and cannot be used to film videos with better audio quality. The SHIDU S611 has been beneficial to some customers in different areas, such as in classrooms, coaching, and outdoor activities. The rechargeable battery included and the wireless system are notable pros, while a few customers have expressed concerns about its low volume and short battery life. There have been complaints about the headset that doesn't hold a charge and not being able to receive a USB port to charge both the mic and headset at the same time. Additionally, it can't be used as an external speaker, so it's not ideal for those who want better audio quality when filming videos.
