Who wins on what

Ranked by what users actually praise

Overall Impression

Sound quality and value stand out as the M3K's biggest strengths. Commenters repeatedly call it the best DAP under $100, citing punchy, forceful sound, good power output for the price, and a night-and-day improvement over phone listening. Several buyers describe it as an unbeatable bargain at £60-70, especially paired with budget IEMs. Some note typical FiiO character with harsh mids or limited bass extension, and one user found power output too low for demanding headphones.

Navigation and UI are the most consistent pain points. Many users struggle with the touch-sensitive scroll bar, especially browsing thousands of songs without a way to jump to a letter or scroll quickly. The lack of dedicated physical buttons and absence of a hold switch to prevent pocket presses also frustrate owners. Several found relief by using arrow-key navigation or installing Rockbox firmware, which noticeably improved control responsiveness and added EQ options.

Reliability and software quirks affect a subset of users. Multiple commenters report units failing after a few months, including crackling audio, random restarts, or getting stuck on the welcome screen, with some replacements failing again. Others mention SD card recognition requiring re-ejection, unsupported file formats like DSF or APE, and a fast-forward crackle glitch. Many owners, however, report no major issues and long-term satisfaction despite these scattered complaints.
