For the sound evaluation, I used a wide variety of ear speakers, including the Tipsy M5, Binary Audio EP321 MEMS, QoA Martini IEMs, Sennheiser HD 6XX, FiiO JT3, FiiO JT7, and Moondrop Horizon headphones.

Instead of doing my standard 24-hour burn-in, I did more than 50 hours of burn-in as I was busy with other reviews and could not review the XM2 right away. And also to test the battery life and charging times.
