What Redditors Say
Best praise vs top criticism for FiiO K5 Pro
Best Praise
+45 ptsβIt's quite strange that they tell you it has to do with impedance, because the FiiO K5 Pro has a very low (2.2ohm) impedance output. It should work perfectly on paper.β
r/headphones
ViewTop Criticism
+44 ptsβYeah, I'd be curious to know what source OP is using. There was a guy here recently with a Fiio K5 Pro, I think, that was frying his right side drivers. Coincidentally, my dad also has a K5 Pro and his Audio Technica right side driver gave out recently.β
