“they are really nice”— @peanutbutterbean1738 on YouTube
“Insane audio quality for 5 bucks.”— @BernardoOne on YouTube
“KZ EDX Pro never sounded good in the first place. Very V-shaped sound which bleeds all over the mids. The bass is although pretty satisfying. The treble is sharp and mids are practically non-existent.”— Paulex57 on Reddit
“Your efforts made this 67 year old smile from ear to ear while listening to my classic rock playlist”— @tedz-kk3vf on YouTube
“reformed mine like a month ago and theyre still holding their shape and feel soooo much better than the original form”— @deathsaidhello on YouTube
“Really disapointed in them, they just dont fit my ears well :/”— @Wizzardus on YouTube
Real owners lean toward the Zero Red: 63% of 38 owners recommend it, vs 57% of 121 for the KZ EDX Pro.
Owners point the KZ EDX Pro at first-time IEM buyers on a very tight budget, and gamers wanting soundstage and footstep positioning for FPS.
Owners point the Zero Red at budget-conscious listeners wanting a natural, well-balanced tuning under $100, and gamers who want punchy bass and detail for FPS/console play off a dongle.
The most-cited downside of the KZ EDX Pro is flimsy cable that oxidizes, turns green and fails. For the Zero Red, it's wide/large nozzle causes discomfort or pain, especially during longer listening sessions, and doesn't fit all ear shapes.
