Synthesized from what Zero Red owners say — not a spec sheet.
“the RED is excellent.”
“Your efforts made this 67 year old smile from ear to ear while listening to my classic rock playlist”
“Really disapointed in them, they just dont fit my ears well :/”
“Not changing the nozzle or upgrading the drivers is a fat L”
“reformed mine like a month ago and theyre still holding their shape and feel soooo much better than the original form”
“i think the bass is great on them and i cant find a single fault OTHER THAN the fact that when my skin/hair gets them abit oily the tips end up staying in my ear”
“Just get the reds tune them to give you better footsteps audio will change drastically depending on tips you use anyway.”
“These Red and Blue chonky boys give me such serious ear fatigue after like an hour of use cuz those nozzles are like, 6.8mm or something”
“Red is better all around, its tuning is very safe and the ohm adapter gives it the needed bass increase for movies and gaming.”
“Those are not reference. They have boomy bloated bass and shite detail from the soft upper mids. Not reference at all.”
“I have to say I'm very impressed”
“Zero:RED is FAR from being reference tuning. The mids on this is too clean to be reference tuning that's applicable for studio and stage use.”
“I have both now and the bass on the red is wayyyy better in terms of amount, extension and separation from the mids.”
“It’s lovely and boring.”
“they sound quieter than my hyperx cloud II and "tinny" if that makes sense”
“Yes the red is a good iem but there isnt a reason to be excited about it anymore.”
“I just find the Reds thin, honky and a bit shouty.”
“Red for music”
“At $50 it's not even close to Ua Guangzhi tbh.”
“The sound is nearly perfect and closer matches my home theater system now. Good stuff for $50.”
“These IEMs are great! Got them on release and can't stop listening to them.”
“I bought these and got bored in a hurry !”
“it’s a good iem for the money”
“I would recommend these over any pair I can think of short of $300.”
Practical notes owners raise — setup, quirks, and issues to watch for. They don't say whether the person likes the product, so they're not counted in the score, but they inform the pros, cons, and who it's for.
“Probably not, but I've only heard the zero red out of these. They are very close in sound, with the zero 2 being cheaper (and bulkier).”
“This is fine on your of and Android sources, but iOS does not support EQ apps, so you’re stuck with the stock presets offered.”
