Our Verdict

Audeze LCD-X

Audeze MM-500

The Audeze LCD-X and Audeze MM-500 are similar wired open-back headphones meant for professional use. The LCD-X are heavier, and have a warmer sound profile, which you may prefer. That said, both are comfortable, well-built, and easy to drive with portable devices. Both the MM-500 and LCD-X also come with a hard carrying case and use mini-XLR connectors for the headphones. That said, the LCD-X cable terminates with an XLR connector meant for the source device, while the MM-500's has a 1/4" TRS connector.
