I'm looking to purchase new wired headphones suitable for my workstation. I need a model with an impedance that matches the amplifier built into my motherboard. My Asus Pro WS X570-ACE lists its specs online, but there’s no mention of the MB output impedance or any guidance from Asus’ support pages. I’m curious about how this compares to the Supreme FX used on ROG-Strix boards, which provide clear impedance details. I also want information on Realtek S1220A versus Supreme FX, and I’d appreciate insights from musicians or sound engineers. For reference, a typical high-impedance headphone is above 150 ohms, while mobile phones and laptops usually use 30-50 ohms. I’m wondering if my motherboard supports that level and whether trying different headphones like the Beyerdynamic DT770-pro (32/80/250 ohm) from a PC’s board gives useful comparisons.
Even if a manufacturer claims professional audio quality, dedicated hardware often provides better results. For impedance and detailed specs like these, the built-in connectors on a motherboard may fall short. Motherboards contain many components that can affect sound, introducing distortion, hiss, or glitches. Even labeled "shielded pro-grade" audio might not deliver the clarity you need. An external amplifier can help maintain a cleaner signal without interference. I don’t suggest relying on standard "pro grade" motherboard audio.
