The Line out is a 3.5mm mini jack output which will drive headphones, and it worked in that capacity for me, so it should be compatible with any 3.5mm "AUX in" input. However, I used Line out only with headphones, and not as an input to a device other than headphones. --- ## 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/99437577-fiio-d3-d03k-essential-edition-digital-to-analog-audio-converter](https://www.desertcart.tn/products/99437577-fiio-d3-d03k-essential-edition-digital-to-analog-audio-converter) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-09*
