The sound is clear, professional, and works great for recording vocals and everyday audio use. ### ⭐⭐⭐⭐⭐ Review *by A***S on January 24, 2026* No lo dudes, funciona exelente! Muy buen alcance. Funciona con una sola pila. ### ⭐ Really wanted it to work :{ *by H***R on February 19, 2020* This mic looked like a good mic for the money, but it had sound issues. By sound issues I mean distortion from the receiver even though the mic was not in the on position. The red light came on immediately and I knew I was in trouble. I found out later that the light would actually go off when the mic was in the'on' position and then it worked fine. But as soon as it was turned off, bam. Nothing but amplified noise. I thought I might work around that issue by leaving the mic on standby when not in use, but another problem popped up when I started to test the distance of the unit. The sound of the mic would go on and off, and pop constantly. Too much trouble for something that just came out of the box. The sparse instructions did not help, (I tried). BTW the sound of the mic was not bad. Maybe it would work better in another environment with no other cordless mics, but I had to return it. Perhaps it will work for you? ## Frequently Bought Together - AKG Pro Audio WMS40MINI Vocal Set Band US25B Wireless Microphone System, with SR40 Receiver and PT40 Mini Pocket Transmitter - Monoprice XLR Male to 1/4-Inch TRS Male Cable - Gold Plated, High Fidelity and Eliminate Noise in the Recording Studio and On Stage, 16AWG, 6 Feet, Black, 6Ft --- ## 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.kr/products/43498840-pro-audio-wms40mini-vocal-set-band-us25b-wireless-microphone-system](https://www.desertcart.kr/products/43498840-pro-audio-wms40mini-vocal-set-band-us25b-wireless-microphone-system) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-05-16*
