My kind of neutral, improves a lot on my favorites. Jaytiss Youtube Channel
Overall it is sounding more visceral and incisive than the Performer 5.Super* Review original ranking

A detailed, engaging all-rounder that's exciting without being shouty or harsh. Smooth, neutral tuning with a bass boost, excellent bass quality, clean mids, forward vocals, and sparkly, incisive treble. Great detail. I wouldn’t change a thing.Gizaudio Axel original ranking

Clean, balanced, neutral sound with good layering and tech. Relaxing vocals, but lacks power and last bit of vocal extension. Bass has good controll, but lacks impact. Has sizzly planar timbre in the treble. Safe but forgettable. Jays Audio Youtube Channel

The AFUL Performer 5+2 (also listed as “Performer 7”) uses a 2DD+4BA+1 micro planar driver array and AFUL’s LC-network crossover plus a 3D-printed acoustic tube system, aiming for clean band splits without smearing. The shell also integrates a high-damping air-pressure balance system, a design AFUL has used across its line. Official listings put MSRP around $229 and outline the same core tech features.
Tonally it trends neutral with a sub-bass lift: bass has solid depth and texture, mids stay relatively linear, and the presence/treble region adds energy without veering into sharpness on most chains. Multiple reviews characterize it as warm-neutral with bass boost or slightly V-shaped depending on perspective, which matches listening notes about a lively but controlled upper end. Sensitivity and load are portable-friendly (≈109 dB, 15 Ω), so it reaches performance without demanding amplification.
Technicalities are competitive for the class: imaging is tidy with good instrument separation, micro-detail retrieval is above average, and soundstage is moderate (more width than depth). Build and comfort are typical resin-shell fare; some users note occasional lower-treble bite depending on tips and recordings, so treble-sensitive listeners may wish to pair accordingly. Overall value is strong at its price, especially if a clean, bass-supported neutral curve is the priority.

New Meta tuned IEM. This gives you a bass boost and it's not the best bass. If you want the Hexa + Bass this is what you want.Super* Review original ranking

It's boring. So boring, like mega boring to the max. Jaytiss Youtube Channel

Just get Odyssey it's better. Warm/bassy with solid vocal and treble extension (not buried) that scales really well with good treble air to not sound too intimate. Has a fuller noteweight with one of the best low-ends under $200. Recommended to be listened at higher volumes. A mid-volume version of the Explorer, bassier, and more open.

Almost dead neutral tuning in the best of ways Lacks excitement, bass is alright Tim Tuned Youtube Channel
Solid reference. Great Meta tuning. Could use more detail, not very engaging.Gizaudio Axel original ranking
