Review on 🔊 Portable VoiceBooster 10Watt Black MR1506 Voice Amplifier by TK Products - Ideal for Teachers, Coaches, Tour Guides, Presentations, Costumes, and More by Michael Morgan

It's clearly not an Apple product, but for the price this thing does what it's supposed to do. We do walking tours in groups of 12-20 people and this thing does a great job of getting my voice to the people in the background even when I'm standing outside. It has a strap that can be worn around the waist or over the shoulder. In any case, I can rotate the speaker from back to front, whether I'm walking in front of the group or facing them. Very compact, surprisingly loud when needed. Robust construction. Reloads quickly. I can't vouch for how long it lasts on a single charge - at least 90 minutes for our tours. The only small issue is that the headband wire that runs behind the head and over the ears is too big (and I have a big head). Overall a very good product for the price.
