Review: Finally found one that works very well! - Because of a sudden problem with my voice box, I needed to get a voice amplifier urgently, so that I could talk very quietly. My voice therapist said that I could find one that's OK for about $30, so I started with testing 4 of wired ones in that price range, as well as a wireless system that a friend loaned to me, and two sets of wireless lavalier mics connected to my amplifier . After spending countless hours in the first two weeks trying to make any of those products work well enough for my teaching, causing tremendous frustration, I ordered this one. It is three times the price but what a difference! The sound is clear, the mic is wireless and omni-directional, so the amplifier does NOT need to be on my body, connected to the mic with a wire but far enough from it and other devices in the room not to cause interference (awful shrieking), and the mic picks ups much more reliably, without echo. Not to mention the multitude of additional functions that actually work. In AUX mode, it can be used as speakers for just about anything with a 3.5 mm audio plug or 6.35 mm with an adapter or some other sound adapter. It even works with a different brand of wireless mics if its receiver is plugged into the AUX jack. In Bluetooth mode, it works with my iPhone and the like. Using the microphone jack, I was able to make a powered condenser mic and mics of other voice amplifiers work. There is also a mute button, which I really wanted, and an SOS siren that I'm not sure I'll ever use. The unit is certainly too large to carry around just for that, but it could save someone from a sticky situation while carrying it. It's also possible to play music with it from a jump drive, TF, or connected device, and to make a short audio recording, though I am not interested in those, so I have not tested them. The unit is also supposed to be waterproof and able to tough. By description, the charge should hold for many hours. I have not yet been able to use this unit enough to attest to that but, based on my experiences with this unit so far, I have a good feeling about it. Should my expectation not come true, I plan to update this review. Regardless, I really wish I could guy a second microphone, so that the batteries of two microphones would last as long as one amplifier's. I am really excited and relieved that I finally found a void amplifier that may be truly helpful in my situation, rather than a source of immense frustration, one that allows me to provide the learning experiences of the same quality as under normal circumstances. Update: The AUX jack seemed quite tight at first, but worked a throughout the testing period. However, within a week or so, something inside seemed to move or break and it no longer registered anything connected to it. No AUX devices could be used with it. I contacted the manufacturer and they promptly sent me a replacement. Excellent customer service! Hope the AUX port malfunction was an odd event, and the replacement unit will work for a long time.
Review: 10/10 Voice Saver - If you are trying to decide between this voice amplifier vs one of the cheaper, wired ones, I would encourage you to go for this one! I have tried both and experienced a lot of feedback issues with the wired amplifiers but have not experienced anything like that with this one. My voice becomes clear to the back of the room even when speaking at a very low volume. The battery life problem hasn’t really been an issue for me and I really appreciate the convenience of them providing a dual USB-C chargers so you can charge the speaker and headset at once. I coach an outdoor color guard team so I am constantly competing with instrument sounds outside and have come to rely on this speaker to save my voice. I also love that I can connect my phone via Bluetooth but honestly sometimes just end up holding my phone to the microphone because I get lazy. This speaker connects easily and transmits clearly so I would say it works very well. I am satisfied and will most likely be getting another set to keep in my classroom.

### ⭐⭐⭐⭐ Annoying battery issue
*by P***Y on August 14, 2025*

This item is still working. It amplifies pretty loud for a decent classroom size. One thing I noticed from using this for a year or more is that when the battery is fully charged over night, somehow it goes to zero on battery and it won't work when turned on the next day. You would have to unplug and charge it again. What I did was just don't charge it over night and just turn it on when I am using it and plug it in when it is in use and it won't give you a drained battery since it is in use as it is also charging. Nothing has broken, yet, so good quality except for the battery annoyance.
