Youtube Video Summary

Aful Performer 5+2 lands as a hybrid of the beloved Performer 5 and the punchier Explorer. The unboxing is the familiar P5 affair—same case, same style of tips—nothing flashy, but solid. The shell mirrors the P5 in size with a comfy little stabilizing wing that locks in well. No metal nozzle or front filter here, yet tip retention is secure and hassle-free. The flat 2-pin socket is straightforward, and the stock cable feels thick and supple with a reliable chin slider and handy red/blue channel markers. Overall: understated build, great ergonomics, daily-driver ready.

Sonically, this one aims neutral with a very distinct top end—clean, dynamic, incisive. Think switching from black-and-white to color; cymbals and overtones pop with a slightly crunchy/pristine edge that energizes detail without turning harsh on good recordings. Bass isn’t about sheer quantity; it’s about slam and dynamics—quick on the draw, well-controlled, and satisfying when called upon. Vocals sit a notch forward, microdetail is strong, and the overall presentation is coherent, clear, and technical with convincing stage, resolution, and imaging. Not a treble-shy or bass-bombed tuning—more a refined all-rounder for those who want clarity and bite.

Versus the original P5, the 5+2 fixes the missing “air” and soft edges, trading them for crisper transients and better extension. Compared with Explorer (a value champ), the 5+2 brings superior upper-treble reach, detail, and vocal focus. Against Performer 8 and Cantor, it feels more visceral—the P8 is smoother and more relaxed, while Cantor pulls finer microdetail but with less bass slam. Sets like Dino Quattro or J’s Estrella bring bigger fun or treble theatrics, yet the 5+2’s balance and everyday versatility win more often. Net take: a neutral-leaning, highly technical upgrade that stands tall in its bracket—easy to recommend to anyone chasing clarity, speed, and controlled impact over pure warmth or excess bass.

It's boring. So boring, like mega boring to the max.
Youtube Video Summary

Build & accessories: understated box, a surprisingly nice cable with a “juicy” feel and flat 2-pin connectors, plus extra filters. The stock tips are the weak link—thin out note weight and feel downright horrific, so a tip swap is recommended. The medium-to-large shell is a highlight: secure fit, comfy nozzle size, and a handsome faceplate that looks premium in ear. Overall ergonomics and finish scream daily-driver friendly.

Sound: impactful, well-judged bass, lively upper mids, and a touch of upper-air jank; for $200 it’s a strong value with a clean, modern JM1-style tuning. Easily the most convincing Kiwi Ears to date: more balanced and natural than Quintet (which pushes upper mids/10 kHz energy), far more sensible than the treble-shouty Forteza, a clear upgrade over budget options like DLS and the tiny, poorly packaged Singolo, and less fatiguing than the bass-and-upper-mid heavy Melody. Against $200 benchmarks, KE4 becomes a new reference—cleaner male vocals and better build than “Chopin,” and a tighter low end plus tidier mids than AFUL Performer 5. Trades blows with Hype 4 at a fraction of the price; those craving a pricier step-up in the same vein can eye HiSenior Mega5EST. Measured verdict: Tier A, 3-star, 8.8 for tone—good imaging, solid soundstage, gamer-friendly, not flawless but genuinely excellent once re-tipped. A handsome, comfortable set that delivers outstanding value for newcomers and gift-givers alike.

Solid pick for the price, if you're after a warm neutral sound.

Pros
Overall very pleasant balance with good tonality and perceived technicalities for the price.
Cons
Bass can come off slightly boomy and a bit disjointed sounding at times, and somewhat relaxed upper mids gives a perception of bluntness to the sound, most evident on snare and other percussive strikes.
