Sennheiser MOMENTUM True Wireless 4 Noise-Canceling Earbuds
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 .
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
It's pretty good for the price, good bass and well maintained treble.
Okay, let's talk about this transparent protective case. If you own the MOONDROP ST2s, this case isn't an option, it's a must-buy. Why? Because the original charging case is lidless and instantly attracts dust and scratches!
Fit and Feel
The fit here is fantastic. It slides on perfectly—it's a snug fit with absolutely no loose gaps, which is exactly what you want. Even though it's super affordable, it feels like genuinely good quality in your hand.
Protection and Design
This protective case does its job perfectly: it seals up the whole unit, protecting the original case from dust and scratches. The magnetic lid on this new case works really well, too. You can shake it all you want, and it won't pop open, which is great insurance against the buds falling out of the original lidless design.
I love the look. The transparent design is super cool because it lets the charging case shine through and reflect its original form, all without adding any noticeable bulk.
Just a Quick Heads-Up
It's important to note that the protective case doesn't block the charging port. This means if you travel a lot, you'll still need to keep an eye on that port and clean it regularly to prevent dust buildup.
Final Verdict
My advice is simple: you need this case. Go buy it! Otherwise, you'll constantly be putting the ST2s in a separate IEM box just to protect them. Honestly, doing both—using the protective case and the IEM box—is the best bet for extra protection, which is what I'm doing now.
Okay, seriously, these little earbuds absolutely blew my mind.
The whole vibe, right from the moment I cracked open the box, felt super new and cool. Like, this isn't that same boring, generic crap you always get. The charging case? Totally unique! It looks awesome, but heads up: I can already tell it's gonna be a dust magnet. To keep mine fresh, I slapped a protective case on it immediately and keep the whole setup in a tiny IEM box for peace of mind. Just a pro-tip! Other than that, the actual earbuds fit like they were custom-made for my ears.
But the sound, man? That’s the whole reason to buy these. It’s just miles better than any regular Bluetooth headphone I’ve used. Everything is so dang clear! You can hear all the different instruments perfectly, like they’re standing in separate spots instead of being a messy blob. Oh, and download the app! You can tweak the settings to make them sound exactly how you like.
There are definitely other options out there in this price bracket, but these guys win, hands down.
That separation in the music? I felt it for the first time ever, and it made all my old playlists sound brand new. If you want that super crisp, detailed audio without emptying your wallet, you HAVE to try them. Huge step up! The volume is a little low, but honestly, the ANC (Active Noise Cancellation) covers that right up.
The Technical Bits
The controls are quick and easy to use, but they're super sensitive, so you might accidentally pause your music a couple of times while adjusting them. You'll get the hang of it, though.
For calls, they're fine in a quiet room, but you gotta speak up. If you're out near traffic, the person on the other end is definitely going to hear the cars more than you.
Watching videos? Zero lag. The low latency mode works perfectly for YouTube and Netflix sync. Sorry, I don't really game, so I can't tell you how they handle laggy mobile FPS games.
Battery life is decent—I got about five hours with the ANC constantly running.
Just a heads-up: If you already own a wired IEM, don't bother with these. Wired is just way better. I'm only just starting my journey into audiophile stuff, and I can already tell you: wired beats wireless every time.
P.S. Huge shoutout to The Audio Store for the crazy fast shipping and good packaging! Definitely buying from them again soon.
Awesome Product!

Great Dac
Excellent sound quality
I got suggested this on reddit. Trust The Audio Store.
Value for the price. You can enjoy music at a different level.

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.
I am writing after 1 year and I can tell you definitely that this dac is best in beginners section
Good product
These are absolutely the best bang for your buck case. Simple, spacious yet compact and sturdy.
Best value for money and handles most of the consumer earphones/iems for the beginner audiophile
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.
