"worth the blind buy for bass head on a tight budget."
"especially for the price ... The price point on budget iems is low key dangerous for audiophiles!"
"the discovery that budget IEM's, in my case, starting with the CCA CRA (revised edition - i.e after the retune), could sound even better than my cherished AKG K702, was such a revelation."

"By and large one main issue with KZ/CCA is the possibility of level imbalances between left and right earpieces, it seems to be a bit more pronounced, compared to IEM's from other manufacturers."

"Same thing happened with CCA. Their mistake is that they should have labelled PR2 to something like PR2 alternate version or some other name to notify customers that it's not the exact same PR2."
gobolin-deez-nuts 1.0Wow more than me! My favs are ZS12 Pro X, Zenith, PR2 (black mesh), and Vader. How do you like the ZA12 and Hydro? I tried to get a ZA12 but it was a scam listing so I got a ZSN Pro X instead lol, at least it was free. Oh, and original CCA CRA, one of my favorite DDs to this day.

Tsuiichi 1.0CCA CRA original one is amazing, the sub bass and upper mid dip with sparkly treble made it sound so atmospheric and emotional. I get that upper mids give alot of detail and forward vocals, but it can take away the whole vibe and depth of the sound. Especially when you turn up the volume on cra it feels more intense without being shouty. Idk what driver material they used but it feels super thin and resonant which gave it more "x-factor" to me. Sadly after the driver+tuning change, it became shouty and sibilant lol.
WaltzPsychological20 1.0I had the og cra and cra+ in short worth the blind buy for bass head on a tight budget. Other factors can be a hit or a miss.
elfonite 0.7Downgrading PR2 was not deliberate but after running out of stock of certain component, due to unavailability KZ sourced the component from elsewhere which changed the whole tuning. Same thing happened with CCA. Their mistake is that they should have labelled PR2 to something like PR2 alternate version or some other name to notify customers that it's not the exact same PR2.
That's not true. No company world like to ruin their reputation by engaging in malpractices which would be obvious in the public.

Aces115 0.6EDC Pro and CRA are okay
arkizalnds 0.6CCA CRA, left driver stopped working but they’re still somewhere in my basement
Buick6NY 0.6I had the original CCA CRA and lost one of the earbuds. I heard they silently revised the sound signature and rereleased it, so I never bought another one. Still miss that set.
Daemonxar 0.6CCA CRA. So GD bloated. I literally pulled them out of my ears before going back in to finish a quick review. There are people who love them, and good for them. 1,000% not for me.
Ketadine 0.6Not just that model but sub brand models like the qkz vk4 and cca cra also got downgraded after positive reviews and the qc is still bad, both for iems, and cables.
I would go with those for the absolute budget vs kz. I've had QC issues with my kz edx, cca cra and qkz vk4. But I would go with one of the over 2 for a lightning port iphone + item as the best budget price/performance.
