Works well and I like the quirky styling and the machined from solid case. Simple controls, one on/off switch and a second button which is volume control and after a short press in, mode selector. (a longer press returns it to volume mode) --- ## 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.tn/products/57119769-smsl-m9-dsd512-32bit-768khz-headphone-amplifier-dac-ak4490eq-2](https://www.desertcart.tn/products/57119769-smsl-m9-dsd512-32bit-768khz-headphone-amplifier-dac-ak4490eq-2) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-16*
