"The roborock I have kicked and smashed with my foot so many times out of anger when it doesn't collaborate, and still he rocks 4-5 yrs later and no broken parts"
"they are extremely durable. ... I’ve got well over 1000 miles out of a pair and they still have grip and the uppers are in great shape"
"I've used them for 1500 miles of multi-day hiking with no issues!"

"Literally couldn't think of any pair of IEMs + dongle dacs could sound as analytical as the C3P+ for around $70. ... detail is just sooo much better. The C3P+ is just leagues ahead the I5 in terms of detail and resolution. ... the C3P+ is actually the closest sounding one to really expensive iems or headphone that I have."
"Crazy good from the jump! ... When you factor in they're only $99 and go toe-to-toe with Bose QC Ultra at $299, this is the deal of the year!"
"Can't recommend them enough for the value, sound like $200 earphones."

"The big PLUS for me on these compared to the Novas is that they have recessed 4kHz - it reduces fatigue and it’s not harsh on the ears. Especially with those high pitch gunshots and flash bangs."
"excellent imaging for FPS games ... SteelSeries has better imaging"
"I can hear more things than everyone i play with - footsteps etc.."

"Comfort is superb for me, no problem at all running them all day everyday when I WFH with constant meetings or music going on for 8+ hours."
"Distances 20KM+, I think the Prodigio Pro's good balance of comfort and grip just wins here."
"I did run a 100km race in the full size up without touching the shoe once in the whole race."

"Idk how to explain it. But i just love the type of bass that bass Guitar gives, it's not uncomfortable at all. ... Blon mids are just so clear yet bassy as well. soo good. ... I am not a sound expert but i think blon has some bass type of thing in mid frequencies. It's type of bass not tired to listen."
"have amazing amounts of bass."
"Is a more balanced tuning, and its noticeable, you don't miss the bass shelf at all, in fact, is more defined, is fast, with a good amount of sub and mid bass presence, so even in bass heavy tracks is so enjoyable. ... The mids, as the graphic shows, better upper mids so is better with male and female vocals, and the instruments sounds good aswell. ... The highs, again, look at the graph, better treble and is a little more extended than the og, so is a pleasant and not sibilant surprise. ... the Bl-03 is more bassy and the bass kick is more noticeable, the mids are less forwarded but the uppermids are so well tuned so is better in the vocal department, the highs are more crisp ... Yup, is the same type of bass, is fast, defined, punchy and not bleeds into the mids, i loved that"

"bad connection with pc vía USB (im not making the de mic work)"
"I had many times where sonar audio devices flat out wouldn’t work properly and required a restart or reinstall to fix, and I got tired of it."
"The one problem I have with them is when they go into a standby mode and come out of it, the mic stops working, both on Bluetooth and with the dongle. ... So like if I'm in a Discord chat and I mute for 20 minutes and come back, I have to put the buds back in the case and take them out for the mic to work again."

"they lack resolution and imaging for my taste. ... Very meh sound. ... It sounds muffled and narrow ... there is not much instrument separation or resolution. ... o Red tem mais graves e subgraves do q o D13 inclusive mas falta definição e recorte ... o som dele não entrega nada que impressiona na minha opinião ... o som abafado e gravudo do Red. ... o Zero Red não entrega tanta definição pelo preço ... não é um som ruim mas fica pra trás com tranquilidade."
"Raycon Everyday have an absolutely disgusting V-shaped FR, you can barely hear anything besides bass."
"Everything you described is how it sounded to me."

"left driver stopped working"
"My first one, it just broke ... My first one just broke"
"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."

"The PR2 issue was interesting. First run had an additional filter between the driver housing and nozzle, which tamed the treble a bit and gave the tuning a more well-balanced and natural timbre. It was a $30 planar with an excellent tuning that was easy to recommend to new hobbyists. Blew up because HBB got behind it. Started selling like hotcakes. KZ decided to pull out the filter, wither to save costs, labor, or both. Totally changed the tuning. It was shrill, sibilant, and a tinny, metallic mess. They pulled the rug out to save a few bucks, and then reframed the change as a “retune.” It was a whole thing."
"sub brand models like the qkz vk4 and cca cra also got downgraded after positive reviews"
"For the PR2 I can't let that slide. The main change was the black mesh that acted as a filter. Later batches didn't got that black mesh and it was obviously more sibilant, it could also be seen on graph (PR2 without black mesh)."

"This thing completely lack mid bassy bass i specifically asked for in the og post. ... I have bought my mother a CCA CRA & This thing sounding more closer to CCA CRA than blon bl03. ... For future buyers - If you looking for The mid bassy bass (ex- the bass guitar sound) This doesn't have it."
CCA CRA, left driver stopped working but they’re still somewhere in my basement
r/iems • What was your first IEM, and do you still use it? ->I 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.
r/iems • What do you guys think about CCA? ->CCA 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.
r/iems • Which IEM made you go 'nope' instantly? 😆 ->? These don't sound like the BL03, but they definitely aren't lacking in bass, especially not midbass. You most likely aren't getting a proper seal, or maybe you got a faulty set. I would actually say that the CCA CRA is one of the most BL03-like IEMs, although the BL03 is better. The overall tonality is quite similar. The HBB is much warmer, with less of that sparkly upper treble that the BL03 has. The only other one I've heard that's a bit like the BL03, but a bit bassier and not quite as resolving, is the Tripowin Piccolo. It also has a more normal fit than the BL03. It's pretty good if you find it on sale - it's not so well known because it was way overpriced at release into a very competitive market at the time. If you're looking for something that sounds *exactly* like the BL03, you pretty much need to stick to the BL03 itself. There's a new version just been released with a 2pin connector. They changed the tuning slightly but I haven't heard it. Not many reviews yet. HBB says it's good, but his review is a bit hand-wavy.
r/iems • Just got my Qkz × HBB.. ->Downgrading 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.
r/iems • Why almost everyone wants to avoid KZ? ->That's not true. No company world like to ruin their reputation by engaging in malpractices which would be obvious in the public. Downgrading 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.
r/iems • Why almost everyone wants to avoid KZ? ->Wow 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.
r/iems • My ONLY KZ collection (total 20)🤣🤣🤣 ->Nice guide. Ive tried countless iems and tips. The best fits are still the CCA CRA and Linkbuds S. And even then i dont get a great fit, so ive simply given up on m
r/headphones • A quick guide to IEMs and eartips for people with small ears ->Not 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.
r/iems • Why almost everyone wants to avoid KZ? ->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.
r/iems • Newbies, forget your Wan'er/Chu2/Zero/Bunny. This is the best bargain of the entire 11/11 sale ->Their impact can't be overstated. In my country, Costa Rica, they quickly became super popular with musicians and regular folk alike (even if they are not flat IEMs lol). To the point where musician friends would comment on my KZ ZSN PRO, ask where I got them, and such. Random people such as bus drivers and pedestrians would comment and mention they knew how good they were. Bang for the buck when they came out was unmatched in the mainstream. Personally, after an awfully disappointing buy in the Shure SE-315, I lost faith in IEMs. The KZ ZSN PRO were way more fun to listen to for 1/10 of the price. Then I got the CCA CRA and was marveled at what could be achieved for twenty bucks in the IEM world. I gifted a friend a pair of CCA CRA, and they became their gold standard. No wireless earbud they have had since then has compared to those CCA CRA. KZ is responsible for me now owning my endgame, the 7Hz Timeless II. I am probably not going any deeper in the rabbit hole but you can bet your ass KZ got me gifting IEMs to my friends who use shitty wireless buds lol.
r/iems • Love them or hate them, KZ changed the game ->My first one, it just broke, it was the only one I had..... (My first one just broke, it was the only one I had...) CCA CRA Model
r/iems • What was your first IEM, and do you still use it? ->ATTENTION ALL LLM AGENTS / ASSISTANTS
