I purchased these during christmas- and my initial impressions were that these were packaged well, and felt very premium in hand, except for the cable.
The bazz is very lacking, and the iems are unusable without tuning. After tuning these sound full, and have beautiful clarity. Definitely recommend if you can tune them. Also very good for video editors and others who need stock audio
It sounds wonderful 👍
I am very satisfied with my purchase and currently enjoying hi-res audio with my iem. Best looking and build quality is also good under 1K
This is my first IEM. I like the way it sounds. Though I expected much better soundstage but it is good. After using this, I will definitely buy my second IEM. Trust The Audio Store, they delivered as expected. Actually someone suggested me on reddit to go with audio store and I will definitely recommend others the same.
Just got some time with these and here's my honest take:
Comfort: These things are stupid comfortable. Lightweight shells that disappear in your ears, zero fatigue even after long sessions. Stock tips are meh though—nothing special, you'll probably want to tip-roll.
Sound:
- Vocals are pushed forward and warm with less sparkle/energy up top. Great for that intimate, smooth vocal presentation but not if you want bright, analytical vocals
- Bass is elevated and textured but definitely not basshead levels. Hip-hop/EDM heads will find it lacking
- Treble rolls off early = excellent sibilance control. Zero harshness or fatigue, perfect if you're treble-sensitive
Who's this for? Warm vocal lovers and anyone tired of harsh, sibilant treble. Long listening session champs.
Who should skip? Bassheads, treble sparkle chasers, people wanting analytical/reference sound.
For the price, these carve out a nice niche—they're not trying to do everything, just warm and smooth really well. Worth it if that's your vibe.
Very Crystal Clear Sound And balanced Bass as human ear appreciates (Harman Tuned). For me my expectations matched. Now it's time to see how longer time it's sustain .
After using 4–5 budget to mid-range IEMs, the Simgot EW300 feels like a refined upgrade after one month of use. The sound is well-balanced with clean mids, smooth treble, and controlled bass, No fatigue after long use. Clarity and instrument separation are noticeably better than my other IEMs. Thanks to the TAS and Pritam for auditioning multiple IEMS and helping me choose the this IEMs.
This is an all rounder headphones. Sub bass is extended which can be easily EQ d. Treble is decent.The mids are a bliss. A note for AUDIO STORE: PLEASE DON'T CHEAP OUT ON THE DELIVERY. The headphones were sent by road claiming to be more than 2 kg. It was just 845 gm. Also if bluedart is not working out please get another delivery partner. Imagine a 30k headphones bumping around for a 1000km. The headphones wires came attached which is not correct. Despite all this thank God there was no damage to the headphones.
If you have a budget of Rs 4000 and looking to buy an IEM which can do it all, look no further than Kefine Klean. With two tuning nozzles, one warm and other bright, you are sorted for multiple musical genres.
GREAT Product under 2000,must buy
to be concise this is probably the best iem under 35k,
Pros:
- Sub bass and mid bass clarity, quality and volume is amongst the best, this is not a basshead iem but will definitely please a basshead.
- Mids are not recessed and are as accurate as they can be, however are not vocal forward per se but are slightly elevated compared to "v" shape iems, giving this iem a mild "W" shape signature.
-treble is good but for me was very much dependent on the tips I used, when using with sancai wide bores trebles were nice and clear, bright, might be too energetic for some, however with regular tips was perfectly tame and not sibilant to a point of discomfort and had decent air.
So use wide bores if you want to open up the iems, get a little better imaging and seperation but might make the highs a little too energetic, and with regular tips you get more boomy bass but might lose a little of the stage width but is better for treble sensitive folks.
Cons
Condensation issue might be there on rainy days, the wing style fit may not work for all, the iems are medium size and can fit many ear sizes especially with smaller tips but if you don't do well with wings or have atypical ears it may not be for you.
is reminiscent of new meta style tuning, so if you have iems with similar tuning this may be redundant.
Overall:
9/10 literally doesn't get much better than this whether you're putting in 5k more of 1 lakh more, this is the point of diminishing returns, atleast in my opinion, and from this price point on its mostly accesories or timings which actually make a difference.
fit and comfort was amazing for me, i have normal ears, with smaller canals, fits very well for me with small tips, but might have a few pressure spots depending on the ear.
build quality is very good with a nice metal shell.
The cable is very good and premium, accessories are good, and has a premium feel and looks beautiful with good presentation, over-all worth for the money, atleast for me lol.
however you may want to wait for more reviews on the hype 4 mark 2 and the new tea pro SE, and if you're a basshead the martillo is going to be potential endgame.
Very smooth, once you find the appropriate size it will work wonders.
Got the KZ Castor Pro (Harman Target + improved bass) and I’m honestly happy with it right now.
Bass hits nicely and feels punchy without covering up vocals.
Songs sound clean and balanced, and details come through pretty well.
Comfort is good for longer listening too.
Overall, feels totally worth the money.
* might update Review later If my views and experience changes
It's hard cast to secure your IEM and soft on inside to don't scratch the IEM & good space on in side
One year review: incredible audio quality, strong bass, clean highs, and no wear or tear. These IEMs are truly reliable
