Owners point the Quintet at detail-chasers who want a technical, resolving IEM at a mid-range price, and treble/fun-tuning fans who enjoy a spicy, energetic upper-end signature.
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 Quintet is treble is too bright, shouty, or fatiguing for a meaningful minority, described as harsh, aggressive, or exhausting especially for treble-sensitive listeners. 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.
