KEFINE provides refined audio products for music lovers at affordable prices and the best value.
So kefine klean have one of the best soundstage and imaging in 12k price range. They provide detailed sound and has decent bass. These are my go to for cs,valo and other BR competitive games. I am not a fan of the sound signature cause I like listening to music on v shaped fun , energetic and bassy iems but the klean serves a purpose for me and I am happy with them.
Grabbed these recently, solid budget iem tbh. metal build feels nice, comfy fit, easy to drive from phone.
pros: balanced sound signature, comes with interchangeable nozzles (silver=warm, black=bright). quality exceeds expectations for the price.
cons: vocals can get sharp and shouty, pretty average bass performance. stock tips kinda suck, cable is just okay.
tldr: decent all-rounder but has some vocal harshness issues. bass nothing special. recommend if you can look past those flaws.
Vocals are really clear. It lacks a bit of bass but that is expected from IEMs which are supposed to be accurate to the sound. Sound stage is also really good for a single driver IEM. The stock eartips are slightly uncomfortable.
I can't go back to my old headphones now, these have changed the game for me. Slightly uncomfortable at first as these were my first iem's, but I've been getting more used to them.
These are my second pair of iems. I'm thoroughly satisfied with its sound, huge upgrade over my KZs. The vocals are clear instrument separation and imaging is great ,and there's little to no sibilance. They also perform really well for gaming.
One of the best birthday gifts for me. :)
I was having a huge dilemma switching from a budget IEM to a midrange IEM and I got this masterpiece... KEFINE KLEAN provides Tank like Build ✅ "Sufficient" bass To Power up Any Tracks and Sound stage Was Better than any Other Iems at this price. As Named The Audio Was Very Clean And Smooth So There'll Be No Distortion At Any Point ...

I have not expected this great audio quality but after hearing the sound this is fabulous and no words to express.
Great product in this price range.
i would say it is best for who likes music and vocal not for the base lover.
Best quality and enhance sound volume compare to one plus and iphone type c converter
Love these, u shaped sound signature but pains my ears after 2 hours of listening.
The IEM's have a decent balanced V shaped profile & the manual EQ settings are quite useful.
After my first pair, the Oriveti OD200 (which I loved!), I grabbed the Martilo as my second set, and wow, I finally get what people mean by basshead. Guys, these are unreal. If you listen to music that's supposed to really H-I-T, this is the one for you.
Sound Breakdown
The Bass is the star: It literally shakes my eardrums. We're talking deep, physical sub-bass rumble, not the muddy, boomy kind. It feels like having a huge subwoofer in your head. It hits hard but stays clean and super fast, which is critical.
Mids are surprisingly clear: I was worried the bass would swallow up the vocals (Mids), but they stay right up front. My favorite singers sound crisp! You get great separation, letting you pick out instruments even when the bass is going crazy.
Treble is sparkly and quick: I think the planar driver is what makes the high notes (Treble) sound so detailed. It adds enough "air" to the sound and keeps the whole picture from feeling dark.
The design is awesome, they look like cracked lava rock, and they are pretty comfortable even though they look a bit chunky.
Only 1 downside for me was the eartips, it could be more comfortable given the price tag of this IEMs. I'm using stock eartips of my another IEMs (Oriveti OD 200) which is surprisingly comfortable.
Final Takeaway
If you are moving up from entry-level and want to know what truly clean, hard-hitting bass sounds like, get these. It’s an easy, near-endgame fun set for people who love bass-heavy genres like EDM and Hip-Hop. Go listen to them!
Works great for any iem out there. I previously only religiously bought apple dongles as my got-to portable dac. Only later I found the audiocular spark which had the CX31993+ Max amp and provided slightly more power. It works exactly like it says and gives 1.4 v vs the 1 v of the apple dongle. So if some extra power is what you’re looking for, the audiocular spark is what you need. This is going to power all your iem needs.
I love these iem’s . This is end game iem for me since expensive ones have diminishing returns
I really like audiostore delivery
Awesome purchase. The KZ Castor Pro Harman Bass Tuned is a dream for audiophiles which will make them enjoy the nuances of every genre of music. Loved it. Wow.
Spectacular DAC, boosts the audio well. Great music experience.
TL;DR:
Finally jumped into the IEM world with the Bunny and I am blown away. Super clear highs with zero harshness, smooth vocals, and punchy bass. Works great across all genres I listen to, super comfy, and keeps getting better over time. Only downsides: cable’s a bit short but that is subjective and movie audio can be hit or miss. Overall, I’m honestly blown away by how good these sound for the price.
I have been contemplating getting into the IEM world for the past few years and when I finally pulled the trigger on this one, it just blew me away and I am not even exaggerating. Before getting these I was using OneOdio Headphones that I got for 4k that I still love but, well, when I got the Bunny's I was like, is this what have I been missing out on ?!?!
This long contemplation for getting an "IEM" was also because of conflicting reviews about some of them like some having high sibilance or thin sounding bass or something else and I couldn't make up my mind to get one or the other. I'll be honest, I was kind of scared if I might not like these or I might find them too sibilant as I am pretty sensitive to that, and I was already expecting the bass to be less than what I am used to before hitting the play button. All of my worries went away as soon as the music started, the highs and vocals were absolutely clear and bass hitting just right. I did try tip rolling to see which eartip gave the best seal. I don't know if burn-in is real or not, but it has been a month since I got them and they have just kept getting better and better.
I listen to a lot of DnB, Experimental or other EDM subgenres along with Jazz, Orchestral, Movie scores and songs with vocal etc and they work for all the genres in such a nice way! I'm seriously trying out new genres at this point because everything sounds so fun with them. The vocals are so smooth and just the right amount of sparkly and the bass either the sub or mid is not at all lacking by any chance. I won't be able to talk much about the soundstage but if I say so, listening to Yosi Horikawa, Snarky Puppy, Tipper is an absolute fun in these. Everything just sounds like it is there as it should be. Separation is great compared to my headphones. I am indeed hearing things that I haven't before but that might also be because of the bass not muddying everything up.
They are small so they fit me like a glove (subjective but still) and are so comfortable to wear for a long session or even while lying down. I just wish the cable were a little longer but its still fine. The included bag is pretty handy and the included tips have a pretty good selection to get a good fit.
I'm definitely getting a DAC and maybe in the future a Balanced cable just to see how much can these be pushed and what sound these can deliver.
The only few things I'd say is that watching movies or shows could be a hit or a miss with these because of the way they might be mixed/mastered and as these being balanced they don't hold back on any frequency or muddy up the other. The other day I tried to watch Chris Nolan's Tenet with this, but the gunshots were a little too harsh or the voice was too low to hear properly but Ford vs Ferrari, Mission Impossible or Star Wars were very fun to watch. Might be a subjective opinion but I thought I'll add it. The other thing is that I thought these would be good for making music as I do that for hobby but I still have to test them out more in that scenario.
It is very efficient and clean sounding. I loved the amplification which is enough to drive demanding planar magnetic headphones. The functions and display is very intuitive. Overall a very good product.
A goodpurchase awesome improvement in the bass with no extra noise!
It is really good for the price
The IEM's are really good. The build quality is great for the price
