Description
Your music just got better with the Sennheiser IE 600. This top-of-the-line IEM is equipped with Sennheiser’s TrueResponse transducers that are specially tuned to bring out the best in every track. Amorphous zirconium alloy housings allow for next-level durability while retaining its lustre for years. Gold-plated MMCX ensure seamless connectivity across multiple source devices.
Experience True Sound with TrueResponse
Enjoy an extra-wide frequency range and ultra-low distortion with the Sennheiser IE 600. It is equipped with high-end TrueResponse transducers. These 7mm transducers are assembled by Sennheiser and achieve the correct channel matching, making left-right differences nearly undetectable. Expect a powerful bass, unrivalled total harmonic distortion and accurate response, all delicately balanced.
High-end Studio Sound, Now in Your Pocket
The Sennheiser IE 600 offers a natural sound that’s similar to that offered by high-end studio monitors. The acoustic back volume inside each IEM’s nozzle has been tuned to add neutrality while bringing about an intimacy that lets listeners discover new accents and details. Additionally, dual-chamber absorbers (D2CA) capture and attenuate similar sounds that occur in a track simultaneously. This creates a level of poise and naturalness while revealing the finest textures of your music.
Designed to Last a Lifetime
The IE 600’s housings have been crafted from zirconium alloy for 3 times the hardness and flexural strength of high-performance steel. This amorphous metal was developed after years of research by Heraeus Amloy Technologies and is fabricated using a metal-powder-based 3D printer. The chamber and channels formed as part of this, require no milling process. While impressive, the cost of developing this new material is extremely high, making it exclusive to only high-end IEMs like the IE 600 and equipment used in extreme conditions (like the drilling head of a NASA Mars Rover).
Made in Germany
The amorphous metal housings are made in Germany. A computer-controlled laser sinters a thin coat of metal powder that’s welded to the already hardened material beneath it. This process continues till the housing reaches its perfect shape after which a skilled technician removes any artefacts of the manufacturing process by hand. It is then cleaned, steel shot-blasted, polished and shock-frozen to prevent the formation of a crystalline structure (like that of conventional metals). This ensures a lustrous surface that’s highly resistant to corrosion and scratches.
Connections that Matter
The gold-plated MMCX connectors support cable diameters of 4.8mm and below. This makes it perfect for a variety of audio sources. The recessed design of the connectors ensures better durability and stability. In the box, the IE 600 comes with para-aramid reinforced unbalanced and balanced cables with 3.5 mm and 4.4 mm terminations. You even get silicone and memory foam eartips in 3 different sizes and flexible earhooks for better fit, comfort and noise isolation.

I got these after listening to several reviews on YouTube. They are precisely what these reviews said they would be.
Thanks for your feedback. We're glad you're happy with the Sennheiser IE 600 IEM!
Excellent IEM
Thank you for the review!
I bought ie600 as my third iem after fiio f9 pro and fh7, i was looking for a comfortable DD iem and my search ended with ie 600, i bought a custom cable along with this because i find default one not good enough, amazing iem natural timbre and nice base, wanted that got the same amazing iem by sennheiser finally in iem game.

The Sennheiser Single Driver IEM has a V-shaped sound signature. The driver is housed in amorphous metal that was 3D printed. You get three pairs of silicone and foam ear tips (S, M, and L) in the box. You get two cables, one with a 3.5mm termination and one with a 4.4mm termination.
I heard enough sub-bass rumble with a decent thump, and the bass is warm but not boomy. The highs are clean with decent air and least sibilance, but for those who are treble sensitive, they can be sparkly or harsh on some tracks.
The decay of the bass is clean and does not bleed into the mids. If you like V-shaped tunes, the mids are laid back and not in your face, which may be beneficial for long music sessions. The holographic sound stage of the IE600 impressed me greatly.
The review is based on Qobuz/AM as a source via laptop onto iFi's Gryphon (using GTO filter) at +61db volume. Please keep in mind that I did not use stock tips, but rather the AZLA Sedna Light ear tips.
Tracks used for this review:
1. 4ware by Deadmau5
2. Rockstar by Post Malone
3. Thriller by Michael Jackson
4. 295 by Sidhu Moose Wala
5. Usure Poyene by A.R. Rahman & Karthik
6. Pathala Pathala by Kamal Haasan & Anirudh Ravichander
What could have been better?
1. The cable quality, which is prone to impressions even with minimal force applied for long periods of time.
2. The stock tips, at least for me, were not a good fit. Although the IE600 sits comfortably and does not feel heavy during extended sessions.

OUR HONEST REVIEWS FROM THE CO-FOUNDERS & AUDIOPHILES
View allTRUSTED BY OVER 35K+ MUSIC ENTHUSIAST
Let customers speak for us
from 4996 reviewsThis is really warm sounding as advertised. Especially vocals are more engaging. The fact that its driven by phone power doesn't affect the sound quality in anyway like in other dacs I have experienced brighter, thin sound or few peaks in upper midrange. If earphones are having good sensitivity then this dac provides good enough power. Although bit bulky build is very good. I'm sure it can withstand frequent drops also. Have not tried the filters and listening to default filter only. One thing I noticed is although on paper power output is good for 32ohm its only good at driving earphones and not headphones. Distortion kicks in when volume is increased even at high gain setting. I'm only guessing current supplying capability for dynamic driver headphones is not sufficient. Tested with 300ohm HD600.
The sound quality is so much better than any other wireless earphones
The quality of wire is superb.
The mic quality is also good.
Length and feel of wire is good. Sound quality with my Tangzu warner is excellent

Have bought this on 17 Aug 2024 and after using it for almost half a year i can surely say this is the best one in this price range...
I like how crisp and clear the audio is, also how good the IEMs respond to EQing, which unlocks a lot whole lot of possibility

Recently bought this after seeing some positive reviews
Fit:
Unlike many reviews which talks about it's fit issue, it's a wonderful fit for me with the stock large size narrow bore tips. I usually go for medium or small size silicone tips but for this one large one fitted well. i guess large size long stem eartips fits well with this iem.
Sound:
Vocals and string instruments sounds forward but never thin or sharp or fatiguing and has a sweet timbre. I guess it's due to its thick note weight and the quality of dynamic driver.
Bass in general is good. But i would prefer little bit more sub bass quantity. Also prefer the bass to be a bit tighter. Not too tight as i am not a fan of too tight bass. Basically here bass decay is slow and i would prefer it to be moderate.
Treble has just enough energy and details but relaxed.
Overall it sounds very nice with a pleasant timbre.
Note that i replaced the stock cable with fiio ls-b 4.4 mm cable.

Great set to start your tip rolling journey!
Got the delivery under 24 hrs.

This is wonderful product and quality is great. Very good working with mic.
And support samsung s22 ultra.
The Moondrop Blessing 3 is a hybrid IEM with excellent performance and a largely neutral sound signature with a slight bass boost. It offers impressive detail retrieval, resolution, and instrument separation for its price.
Pros:
* Excellent detail and clarity: It reveals subtle nuances in music.
* Balanced sound: Largely neutral with a well-controlled bass that doesn't bleed into other frequencies.
* Good technicalities: Strong imaging and separation of instruments.
* Comfortable for wearing for long periods
* Solid build quality
Cons:
* Fit can still be an issue for those with smaller ears.
* The cable could have been better.
Overall an excellent IEM for me.... Well done Moon drop!!!
The KZ ZSN Pro 2 offers exceptional sound quality at an affordable price. With a hybrid driver setup (1 dynamic + 1 balanced armature), it delivers a punchy V-shaped sound signature with deep bass, clear mids, and sparkling highs. The soundstage is surprisingly wide with good instrument separation and imaging. Build quality is solid, featuring metal faceplates and a comfortable, ergonomic design. While the cable and accessories are basic, the overall performance makes the ZSN Pro 2 a fantastic value for budget audiophiles.
Yes it is very comfortable 👍

Best under 2k for balanced sound.

Rarely do you find cases that offer this kind of value. I love it for two main reasons: there's no need to cram your IEMs like in typical compact cases, and it has enough room to fit a dongle DAC comfortably. You can even carry two IEMs if needed. The build is solid, and it feels premium all around. A great pick!

Suggested by Pritam—bought them and loved them. Insane value for the price! A must-have for beginners exploring the tip rolling game. While they mimic some branded ones, the material and build do differ—but the value is unbeatable. Highly recommended!

Purchased a iem from them.Nice packing safe delivery. Will definitely recommend beginner audiophiles to buy it from them.
