Have made these my "beater" IEMs. They sound good to my ears, better than most IEMs under $100. Just don't expect these to sound better than more expensive IEMs. I think the sweet spot is in the ~ $120 range with the FiiO FH3, Moondrop Starfield, or ThieAudio L3 if you want to spend a little more for the next level.

These are one of the harder iems I have heard to understand. I. Actually surprised to see enough people gave these a fair shot trying alternative tips to give these a rating they deserve. With stock tips these had me disappointed after recently getting the CCA C12. Those really impressed me compared to things like the Blon bl-03. Stock the CA16 seemed too bass heavy and recessed the treble way too much.Outside of the obvious increase in resolution and lack of grain compared to the Those mentioned and some others it felt like a down grade. The bass could completely cover most of the other frequencies. The only unusual thing about that fault was that you can still hear the other stuff well controlled underneath. It wasn't like the bass was bleeding in to things but more like the volume of the other frequencies are too low.Sadly the sound wasn't the only negative on first impression but the fit was an issue as well. The stock tips are recessed on the sleeve and the nozzle is relatively short. In addition to that the underside of the iem has a large bump that pushes against my ear with stock tips. That eventually leads to the iem slowly coming out my ear at an angle breaking the seal. If you own some of the other less recent models from CCA or KZ you are familiar with a 4.5-5mm nozzle but these are more like 3.5mm maybe even 3. Most of my tips don't fit.Luckily the stock star tips from those older KZ and CCA tips will mostly fit. If you are something else and freak out thinking you have to run to the hospital to waste their valuable time to get it out then don't do this. I have had the tips come off iny ear many times but eventually found a way to make the tips stay on despite being slightly too loose. The star tips will make the body of the iem sit further out. There is a good amount of space after the nozzle ends before you get to the end of the tip. That increased distance allowed them to stay in my ear and improved comfort a lot. It does make them stick out from your ears a bit more but it's a trade off I am willing to make.Finally to where things improve. I was not originally a fan of the star tips which is why I had them to spare. They seemed to brighten things compared to my usual tips be it foam or silicone. With the CA16 they are nearly exactly what is needed. The bass is toned down a touch but still elevated compared to the C12 and blons. The mids seemed to come up to an acceptable level and the treble loses some of that veiled feeling it had prior.With those tips it is such an enjoyable experience. The detail is extremely impressive for the price and it presents detail in a technical way and not in a bright analytical way. Vocals are very smooth and oddly lacking that grain maybe slight metallic tint from most other chifi BA's. The tips also gave some power back to the female singers that was taken away with the stock tips. Overall they would still be considered a warm iem and though.These have more than enough detail to keep you occupied listening to music allowing you to enjoy the small things you normally wouldn't but they are also a pleasure set. At no point will these hurt you or result in fatigue. Outside of playing them too loud you can listen to these all day without issue. These have become my most used pair since I got the tips figured out and the improvements are painfully obvious going back to the C12 and especially the bl-03. I didn't notice that much of a lack of detail or grain with those but after listening to the CA16 then going back the difference is actually startling.Hopefully lastly I also upgraded the cable. I got it earlier today and it is the 16 core silver and gold cable by Tripowin. I'm trying real hard to find a difference between it and the stock cable but don't know if I can. I only have one pair of the CA16 and there is just too much time between listening when swapping the cable to get an honest opinion. I think I may notice a small difference but don't know if I am hearing the difference because I want one to make a difference. I think I hear a slight boost to the mids and treble with the new cable but even if what I think I am hearing is real it is very minor. The difference I think I notice the most is the trail of vocals and instruments in the treble region. The stock cable seems to have a soft ending edge to words and roundness to the treble. The Tripowin feels like it shaved down the rounded edges adding a touch of crispness. It's actually a good thing but it could all be in my head. LolI'm scared to scroll up and see how long this review is so I will summarize and end it here. These have many issues stock but if you invest the time and effort finding better tips you can get a very good sounding pair of iems that have impressive detail at a reasonable price. Possibly the best detail at it's price.

Me gustó todo, se ven muy buenos, delicados, excelente, gracias.

The sound is fantastic, better than the CCA C12's in terms of soundstage and bass. They are comfortable but I'm using a different set of eartips. They were accidentally washed with clothes but they still work with no issues!

They're definitely warm and smooth to listen to and easy listening all day. It may just be mine that have a problem, but the response curve has definite dropout around 4500 hz and 8000 hz which may be either mine having an issue or just the tuning of these in general. It's significant enough to where certain instruments aren't quite coming through. Something's missing. It may be they tried too hard to remove any sibilance, or it could be I have some bunk drivers in there that aren't quite pulling their weight in the upper range.I have the CCA C12s and they seem fairly flat through the entire frequency range with some very minimal changes around the upper 5000 and 8000 hz range and everything seems more detailed and separated in those relative to the CCA CA16. The lower end of the CA16 definitely sounds great and digs deeper than the C12s, but it just seems like the CA16s are missing something in the upper end. I'll keep listening for a while and see what I get but I definitely have more of a "wow, I hear everything so well" on the C12s. I don't have that same experience with these and am somewhat disappointed as they're higher priced and have more drivers.

Unreal sound quality at this price point. I unfortunately could not keep them but for the time I listened to them, they were superb. Couldn't really afford to purchase them at the time but lost my mains and needed a set before worship service over the weekend. My old ones turned up a couple days later and it was either have an extra set of iems or get my kiddo a birthday present. Will likely be back for another set asap!

I've been trying several of these sub-$30 IEM style buds. I had gone all the way down and tried some $10 ones and sent them right back, so I thought I'd keep trying the ones closer to $20. There seems to only be a few varieties and the rest are all rebranded from the same few.These were interesting because of the frequency switches.Here's my assessment:- without the bass boost, they are too flat to listen to music.- A tiny bit quieter than another $20 set I like- Sound quality is slightly harsher than another $20 set I like, and I would expect these to be fatiguing after a while because of it.Overall, they are still GOOD. Sound quality is decent. Bass boost warms them up a bit.The cable is DIFFERENT than what others are doing. I got a "zip cord" style cable, while all the other ones are a funny twisted braid now. I don't dislike either one, they're just different.So, in the end would I buy these again? Probably not since I found some that I think sound better for about the same price. But I'm not returning these either. They are perfect fine sounding and are totally usable.

I have an expensive one and I compare to CA16 I was surprised when I try it to my onkyo dap the sound quality is close if this can only sealed the ear tips it’s perfect. The only thing that I don’t like about this is the wire the ear part is soft plastic.
