- 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.

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.

## 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.
