A free, open-source Android app for setting EQ on three supported USB audio dongles, with profiles stored on the hardware.

Landing page captured for the 2026-10-06 issue.

For: Android listeners using supported USB audio dongles
Worth noticing: It reads the settings back after sending and stores them only when every value matches.

Field notes

Profiles are named for headphone pairs and stored on the phone; the page warns users to keep a copy because they live only there. The EQ controls reflect each dongle’s limits, including different band counts and gain ranges. Contour is explicitly described as unofficial and not endorsed by the hardware makers, and the page advises using it at the owner’s risk.
