Owners overwhelmingly praise the Truthear Zero:Red as an exceptional value pick, with dozens calling it the best IEM they've heard under $100 thanks to its balanced, natural, non-fatiguing tuning and punchy, well-extended bass that beats gaming headsets and pricier IEMs alike. Many say it works great straight out of a phone or dongle. However, a meaningful minority pushes back hard on the hype, finding it overrated and less technical than its reputation suggests, while the most common physical complaint by far is the wide nozzle causing ear discomfort or outright pain on longer sessions. A smaller group also dings the stock cable and earloop fit, and some find the tuning swings too bassy or too thin depending on taste.
“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.
