## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great!
*by M***D on September 12, 2020*

I used this for socially distanced, masked rehearsals In a park. Our first attempt, before the mic arrived, was torturous. With masks and distance and ambient noise, it was exhausting to get attention, be heard, or be understood.This. Unit made it possible to do the work while maintaining safe distance.I wore the mic inside my mask. The sound quality is excellent. The controls on the wireless earpiece made it easy to mute or adjust volume when necessary. I didn’t play with the controls on the speaker much in rehearsal, but I was able to pair other devices via Bluetooth to play some musical examples.There is the option to wear the speaker unit or set it somewhere. I was working in a 50 sq. yd. space and never went out of range. The speaker fit in my overall or cargo pants pockets when I was moving around. This helped my singers/actors to locate me instead of just my voice coming out of a remote speaker on the sidelines. The speaker, like any speaker, needs to be pointing toward the listeners, especially in an open air setting.Battery life was excellent.

### ⭐⭐⭐⭐⭐ Adds good/easy reverb
*by K***A on March 13, 2025*

I use a lapel mic with my NAF and this amp with the echo turned on when I want some reverb. It works really well, is portable, and easy to use.

### ⭐⭐⭐⭐ Not a bad little unit, don't let its size fool you
*by S***T on December 8, 2020*

I use it in a moving train car. I sing tunes and use the uhf wireless mic with the unit. I accompany myself with a banjo, which is acoustic. I have the 18 w model but thought I'd try this because it had 25 w. I like the placement of the volume knob, the echo effect feature can only be added slightly without sounding horrible. I've used it all day without a recharge, it's a shame there's no way to tell how low it's getting, the 18 w has a digital readout of the charge that is remaining. I left the headphones power on during a break and it ran out on me, but the headphones charge up fairly fast. The 18 w is a warmer sound quality, but I find myself using the 25 w as first choice, mostly for the volume knob convenience. I prefer the casing of the 18w because I know I'm going to scratch up the the shiny casing of the 25w, but it looks nice now, I've used it for four days. (Starting fresh charge each day)
