It is as good as anyone could reasonably expect for the size and price. The mic is on a flexible gooseneck that stays in place and the neck/head ring thing is metal wire covered in plastic. Bluetooth works fine but this is terrible (and not very loud) as a bluetooth speaker for music- not its intended purpose. For speech- and violin- it works fine. Not super loud, just a boost in volume. Feedback suppression seems to work well. ### ⭐⭐⭐⭐⭐ Great little Amp. *by on Reviewed in the United Kingdom 7 March 2026* Great little voice amp. Bought this to use with a costume and totally does the job. The mic that’s supplied works well on the voice pick up and the amps volume is great. For the money it’s well worth the money. Recommend ### ⭐⭐⭐⭐⭐ Works great *by on Reviewed in the United Kingdom 15 December 2024* I had never used one of these devices before but as someone with a naturally soft voice I thought I would give it a try. Well worth it. Really makes a difference and stops people asking me to speak up! It can be difficult to judge how loud the volume is so have someone test it for you (it is easy to turn the volume too high). It is sensitive to feedback so make sure the speaker is pointed away from you. Quick charge and battery lasts a long while.Overall very pleased. ## Frequently Bought Together - NORWII S358 Portable 4000mAh Rechargeable Voice Amplifier with Wired Microphone Headset & Waistband, Personal Microphone and Speaker for Teachers Tour Guides ect.
