I first thought it might be used because of the scratches on the control panel. My wife & I both l examined it to see if it had a protective plastic covering but did not see any edges. Emailed TK to complain - They responded almost immediately to ensure the unit did indeed have a protective covering over the control surface. We looked again and it did indeed have a barely perceptible clear plastic covering - Unit was flawless. It came with a hands-free headset mic, charger, shoulder-strap, and carrying case. The quality of the speaker is amazing! Whether the input is voice, mp3, or FM, it is clear and crisp at any volume...And believe me, this unit will project at LOT of volume. It comes fully charged and provides 10+ continuous hours per charge. My born-again Friends and I will use it for outdoor evangelizing and look forward to drawing a crowd to hear the Gospel of God's Grace; the message of Salvation which comes through repenting of our sins and placing our faith in Jesus Christ alone as Lord & Savior...And to God be the Glory! Review: Solid Product for Me - Works great and to boot it has an input where you can hook up your MP3 player to speak for you if you're not up task. I use it for open air preaching the Gospel of Jesus Christ. It holds a charge for a long time and sounds really clear for the most part. The amplifier is a sliding bazooka style with a low profile that hangs over one shoulder and rests on your opposite hip.The headset is just OK because it is kind of short and you need to position it it just right. It still works really good, but it just could be better in my opinion. I may decide to get a sleeker headset that is of a smaller profile as well. Either way, it's well worth the price. I recommend this one over all the others out there under the $300 price point. ## Features - POWERFUL VOICE AMPLIFIER: Delivers 25W of amplified sound coverage up to 8,000 sq ft.

BARGAIN! *by C***R on February 16, 2015* OK I'll admit I was skeptical when I read 12 Hours on a single charge. So out of the box it's fully charged according to the tiny manual so at 8:30AM today I fired it up playing a local radio station *L*O*U*D*, then I went out. I come home at 10:30PM and she's still blaring out music! That's 14 hours and still going strong! And it's *L*O*U*D*. It includes an over-the-ear mike with windscreen, a 3.5mm stereo male to 3.5mm stereo male cable which can be used as an antenna or to hook up an iPod. It's kind of short and not gold plated so I plan to replace that but it's functional. I'm totally delighted with this - it even comes with a storage bag and adjustable carry strap. It's the size of a can of Nana Brown's beans but not so heavy. Two things I find strange is they say to "auto-scan" the FM radio stations but after doing that I don't seem to be able to change frequency except to the channels it found in the scan. I'd prefer to be able to tune in some of the weaker stations that didn't get programmed when I did the scan. The other thing I was surprised to read was they recommend you let the battery do down to DEAD before recharging. I wonder what chemistry that would be? ## Frequently Bought Together - Voicebooster Speak Out Personal Voice Amplifier – Portable Speaker with Microphone Headset for Classroom, Tour Guide, Presentations - Built-in MP3 Player & FM Radio – 25watt Black MR-AK38 - Voicebooster Speak Out Headset Microphone Lightweight Adjustable Boom Mic with Feedback Control - 3.5mm Plug for Voice Amplifiers for Public Speaking, Classroom Teaching, Tour Guiding - Voicebooster Speak Out Dual Tie-Clip & Handheld Microphone 3.5mm Wired Mic with On/Off Switch for Voice Amplifier, Public Speaking, Teachers, Costumes, Presentations – 39" Cord in Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/4684818-voicebooster-voice-amplifier-and-mp3-player-mr-ak38-by-tk](https://www.desertcart.gr/products/4684818-voicebooster-voice-amplifier-and-mp3-player-mr-ak38-by-tk) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-10-17*
