An absolute life-saver for recitals! I suspect the reviewers have forgotten what live music actually sounds like! Theyre very sturdy and easy to stick onto the wall. They make acoustic instruments sound amazing just like you hear them in the room thanks to their flat response and the 10dB pad is cool for when you want to mic an amp or drums. The audio quality is abysmal, I tried it with windows sonic, I tried it with Dolby Digital, and I tried it with ICUE native software. 😊😊😊ENJOY, this series 🙌 It is pretty loud as well, matter of fact I had to keep it at 65%-75% volume because I didn’t want the neighbors to complain. I normally wear a size 6 (59" 150lbs), but i ordered the medium rather than small (what the manufacturer sizing chart put me in) because I like my dresses on the longer side. Frogg Toggs sells a unique product. I do have a couple niggles, but thats no fault of the product, nor was I mislead buy the listing.
