“Every penny, just first thing to do is to swap the oem cable with a balanced one and you'll be blown by the amount of bass and clarity.”— lnt976 on Reddit
“I consider them to have a balanced neutral response. It has been my gold standard where I compare every other IEM to. Well worth the cost in 2026.”— Gransmithy on Reddit
“Man I got scammed like you when I bought these iems some years ago haha these things only work well if the recording of the songs is absolutely perfect”— morkfjellet on Reddit

Real owners lean toward the Zero Red: 63% of 38 owners recommend it, vs 48% of 77 for the Etymotic ER2XR.
Owners point the Etymotic ER2XR at frequent flyers and commuters who want passive isolation rivaling ANC headphones, and studio/analytical listeners who want a flat, accurate reference-tuning IEM.
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 Etymotic ER2XR is deep-insertion fit is uncomfortable for many, with complaints about painful, tugging, or fiddly insertion and removal. 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.
