## Description

Nefficar Portable Voice Amplifier for Teachers – Wireless Mic with Bluetooth Speaker - Headset Microphone – PA System for Classroom – 15W Loud Output : desertcart.in: Musical Instruments

Review: Best Product at Good Price - I've been using the N511 wireless amplifier for a few weeks now and honestly, it's a total game-changer! I'm a teacher and having to shout to be heard was starting to wear out my voice, but this little device has made my life so much easier. The sound is super clear and loud enough for my whole class to hear me even in a large classroom. I also tried it outside during a school event and it projected my voice really well. The wireless mic is so comfortable to wear and you don't feel restricted at all, like you do with wired ones. You can just walk around and talk naturally without thinking about staying close to the amplifier. Pairing it was also super easy, didn't even have to read the instructions (though they're there if you need them haha). Battery life is pretty decent too – I used it for about 5-6 hours straight without needing to charge. I also love that it comes with multiple ways to connect, like bluetooth and aux, which means I can even play music through it during breaks. Only small downside is that the headset sometimes feels a little bit flimsy, but I think it's more about me being clumsy than the actual build. All in all, worth every penny and a must-buy if you need something portable but powerful. Highly recommend!
Review: Good - Good product

## Features

- FREEDOM TO MOVE, FREEDOM TO SPEAK – Forget the old struggle with dangling cords and poor sound. Our wireless voice amplifier with UHF technology gives you seamless movement, crystal clear audio, and zero pairing hassles. Most Bluetooth systems can't match this stability.
- DESIGNED FOR TEACHERS, COACHES & GUIDES – Built keeping real users in mind — this teacher microphone speaker clips on the waist, feels weightless, and covers 50–100 people effortlessly. While others compromise on comfort or volume, we deliver loud, clear, natural voice amplification without distortion.
- MORE WAYS TO STAY CONNECTED – Along with the wireless headset mic, we also include a free wired mic — ensuring you stay powered even if the wireless battery runs low. Plus, the built-in Bluetooth speaker lets you stream music or announcements without needing another device. While others leave you stranded mid-session, Nefficar keeps you connected.
- POWER THAT LASTS BEYOND EXPECTATIONS – With a powerful rechargeable voice amplifier (2200 mAh), speak for hours without recharge anxiety. 10–12 hours mic time, 6–10 hours music time — unlike cheap amplifiers that die midway through your class, session, or tour.
- LOUD, CLEAR, AND EMOTIONALLY CONNECTED – The 15W portable PA system ensures your voice feels personal — not like a noisy megaphone. Ideal for teachers, yoga instructors, tour guides, fitness coaches — because being heard shouldn’t mean sounding harsh.

## Questions & Answers

**Q: Which is the best collar microphone supported by the amplifier?**
A: Nefficar Collar Microphone is perfectly compatible with this loudspeaker and offers the same level of clarity as the headset mic that comes in the package and comes with tie clip to easily place it on your tie, collar, lapel, pocket or t-shirt neck.

**Q: Is shidu and nefficar same?**
A: I didn't find any noticeable difference - between shidu and nefficar.

Had bought both of them (few years back).
My wife had to talk in a classroom of 120+ students, and this was a lifesaver for her.

**Q: Can we use tie-clip microphone?**
A: Yes, you can use a tie-clip microphone as long as it is a wired one. To clarify, the tie-clip microphone doesn't come with this Voice Amplifier and you need to buy it separately. What you get with the voice amplifier is a headset kind of microphone that can be either put on head or worn around your neck.

**Q: How far does your voice reaches in open area?**
A: based on the speaker loudness, If the volume is high speaker speaks in high volume it creates noise.

Nefficar Portable Voice Amplifier – User Review I received the Nefficar Portable Voice Amplifier today and tested it right away. Overall, it’s a dependable and well-designed device, ideal for voice projection in classrooms, meetings, or public gatherings. I had previously purchased one for my daughter, and based on her positive experience, I decided to get another one for my wife, who is a teacher. What I Liked: Sound Quality: The amplifier delivers loud and clear audio, even when speaking at full volume. The clarity remains intact without distortion, making it suitable for larger spaces and outdoor use. Wired & Wireless Microphones: Both mics function smoothly. The wireless mic adds great flexibility and ease of use, without compromising on voice clarity. Portability & Build: It’s lightweight and compact, making it comfortable to wear and convenient for extended use. What Could Be Better: Charging Setup: The speaker and wireless microphone require two separate charging cables. It would have been much more practical if both components featured USB-C ports for a unified charging experience. Battery Indicator: A more precise battery level display would be beneficial to prevent unexpected shutdowns during sessions. Final Thoughts: If you’re looking for a reliable and portable voice amplifier with strong audio clarity and both wired and wireless mic support, this is a great option. A few tweaks in charging design would make it even better.
