Norwii Bluetooth Voice Amplifier for Teacher with Wired Microphone Headset

Works fine for a low budget speaker and headset. I use it for teaching and it does help save my voice. The sound is good enough for my needs. I can’t speak to the longevity of its use, but it’s been good so far for the last few weeks.

I teach workshops inside loud venues, like breweries, and I wasn't sure if this would be loud enough for what I needed, but it has worked great! Even with a group of 30 or more people in a large outdoor space, everyone can hear me well. I used it for at least 5 classes (2 hrs per class) and the battery still didn't need to be charged. Worth every penny, and I wish I'd bought it sooner!

Works well. The longest I've used it is 90 minutes at a time, so it holds a charge for at least that long. The headset is cheap and mine stopped working after 4 uses. The mic on the headset is on a bendable mount, so I'm thinking a wire came loose in there from adjusting the mic. I tossed the headset and now I use another lavalier mic I had and it continues to work great. As with any microphone/speaker combo, if you hold the mic near the speaker you'll get a feedback loop and shrieking noise. Overall I recommend this. It's cheap and it works.

Works great. My son uses it for his speech class recordings and it works awesome. Easy to use too.

Good and loud!! connects to bluetooth easily!!

Works great. I teach motorcycle riding and this enables the students to great more clearly.

Barely works. Very quiet, even when fully charged and turned up all the way. Speaker emits random howling feedback shrieks even when beyond the minimum required distance from the microphone.

My daughter got it for Christmas and as a Showchoir member; she loves it! She hasn’t complained about anything! She says she would buy it again!

以前から2,000円代の拡声器を使用していたが 今回の商品は、価格は二倍だが、性能も良く しっかりと音が出るし、充電時間も二倍位あり 安心です

Låg ljudkvalitet och det blir lätt missljud om man höjer volymen. ( Man får vad man betalar för!)

O produto é muito bom! Projeta a voz com nitidez e potência. Funciona muito bem nas salas em que dou aula com cerca de 35 a 40 alunos. Posso falar normalmente, sem forçar a voz...isso faz toda a diferença na qualidade do meu trabalho e na saúde das minhas cordas vocais. A bateria aguenta bem dois períodos de 7 aulas cada. O microfone é confortável de usar e o auto falante é pequeno e bonito...eu o deixo preso no bolso da calça. Melhor aquisição!

Super Teil für jegliche Events man darf es nicht auf die volle Lautstärke stellen da es sonst scheppert aber ansonsten hört dich sogar der letzte Mensch in der hintersten Ecke klar und deutlich. De Akku hält sogar länger als angegeben

I purchased the NORWII S358 Voice Amplifier for my dad, who wanted to use it for evangelism back home in Nigeria. He also planned to share it with fellow brethren for outreach activities. After using it, he shared some positive impressions that really show the value of this product. Here’s what he had to say: Purposeful and Effective: The amplifier served its intended purpose perfectly. Whether speaking to a small group or a larger outdoor gathering, it ensured his voice was heard clearly without the need to strain. Lightweight and Portable: One of the highlights is how light and easy it is to carry. The included waistband makes it even more convenient, especially when moving around during preaching or group activities. Impressive Sound Quality: According to him, the sound is crisp and clear. The microphone picks up the voice well and delivers it with minimal distortion, which is crucial for effective communication in a noisy or open environment. Good Battery Life: With its 2000mAH rechargeable battery, the amplifier lasted for several sessions without needing a recharge. That’s a big plus for areas with limited access to constant power. Strong Amplification: The volume is more than sufficient for most outdoor settings. The amplifier projects sound well, making it ideal for street preaching, teaching, or leading group discussions. Overall Verdict: The NORWII S358 is a practical, budget-friendly solution for anyone needing a reliable voice amplifier—whether for teaching, tours, or ministry. It checked all the right boxes for my dad, and I’d definitely recommend it to others looking for a portable and efficient amplification system.
