The SMSL M20 is a Hi-Res gaming DAC and headphone amp with a 3.5mm single-ended output and a 4.4mm balanced output. It suits PC or console desks that also do music: a gaming headset on the 3.5mm jack, balanced-terminated headphones or IEMs on the 4.4mm, no adapters.
Who the SMSL M20 is for
PC and console gamers: The 3.5mm single-ended output takes a gaming headset, so one box handles game audio on a PC or console desk.
Balanced headphone and IEM owners: The 4.4mm balanced output runs balanced-terminated headphones and IEMs without adapters, so your IEMs earn desk time instead of only commute duty.
One-box desks: If you don't want separate gaming and music chains competing for the same desk space, the M20 covers both from a single unit.

SMSL M20 vs similar options
vs SMSL DS200: Same 3.5mm single-ended and 4.4mm balanced outputs, built on a CS43131 DAC with XU316 USB and Bluetooth 5.1 input for computer-plus-phone listening; pick the M20 for a PC or console gaming desk.
vs FiiO K11: Another 4.4mm balanced desktop DAC/amp, driver-free on PS5 and Switch, but its single-ended jack is 6.35mm rather than 3.5mm; pick the M20 to plug a 3.5mm gaming headset straight in.
