Worked great. Note that there is a switch that must be flipped accordingly to lift the ground as needed. Audio quality seems fine since it’s only MP3 music. Probably wouldn’t buy this for a million dollar recording studio but for my needs, this was an economical choice. ## Frequently Bought Together - FMUSER RCA Audio Ground Loop Isolator, Hum Noise Eliminator for High-Fidelity Stereo Home Theater & Car Audio Players with 3.5mm Ground Loop Noise Isolator - CESS-163-4i Low Noise 12 Gauge Premium RCA Audio Line Patch Cable (4 Inches) - Monoprice 1.5ft Premium 2 RCA Plug/2 RCA Plug M/M 22AWG Cable - 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.co/products/658365687-rca-audio-ground-loop-isolator-hum-noise-eliminator-for-high](https://www.desertcart.co/products/658365687-rca-audio-ground-loop-isolator-hum-noise-eliminator-for-high) --- *Product available on Desertcart Colombia* *Store origin: CO* *Last updated: 2026-08-25*
