Description
Enjoy the true sound of music with the Sennheiser IE 900. This IEM features 7mm TrueResponse drivers with the new XR3 technology for brilliant treble, powerful lows and clear mids. The high-quality build is designed to last and fit comfortably.
Hear Every Detail
Experience the finest nuance in your music with the Sennheiser IE 900. And, it’s not just the tonality of each instrument that is clearly audible, but also the acoustic properties of the room. Immerse yourself in a vast soundstage without any distracting peaks or troughs. An acoustic back volume – a small chamber within another chamber – is used to manage the slope and amplitude of the bass lift. It controls the overall volume and direction of the air as it moves through the driver unit. The end result: Disciplined bass with uncoloured mids.
Built for Brilliance
With the IE 900, Sennheiser has left no stone unturned. The German designed and engineered 7mm TrueResponse transducers offer brilliant treble, powerful lows and clear mids. The drivers are well-tuned to avoid sibilance and overpowering any one frequency. The warmth only adds that much-needed life to your music. The combination of a variety of acoustic materials in the diaphragm ensures a precise transient response and detailed audio experience.
Designed for Pure Sound
The new XR3 technology uses a system of 3 Helmholtz resonators. These are milled right into the solid aluminium housing. The tiny channels in this system prevent resonance peaks that colour the sound. A vortex structure in the nozzle swirls acoustic energy in the frequency bands to smoothen unwanted peaks. Together, these high-end technologies deliver incredible balance and transparency to your music.
Precise Build for Precise Sound
The Sennheiser IE 900 does not shy away from making a statement with its high-class housings. Each one has been cut from a single block of aluminium using 5-axis CNC machined precision. This enhances the electro-acoustic components of the IEM. Once anodized, it is highly resistant to wear and corrosion. The end result? A work of pure art.
IEMs that Fit Seamlessly
Working musicians require IEMs that fit well. And, we took inspiration from this and translated it into IE 900’s form factor. Silicone ear adapters and elastic foam ear adapter sets in three different sizes adapt to the natural shape of your ear for a tailored fit. It does away with uncomfortable sibilance or resonance, letting you enjoy your music just the way the artist intended.
The Perfect Connection
Apart from its sonic properties, a great IEM also offers unmatched durability and reliability. The recessed, 4.8mm-wide MMCX sockets ensure outstanding strain relief. The para-aramid reinforced cable is rated for thousands of bend cycles and terminates with gold-plated Fidelity + MMCX cable connectors on one end and a 3.5mm stereo plug on the other. For audio lovers looking to plug their IEMs into hi-fi audio devices, the IE 900 also comes with symmetrical 2.5mm and 4.4mm cables. The serialised case keeps it safe when on the go.

I didn't expect this kind of sound from this tiny device. Unboxing was underwhelming compared to fiio iems. The tips are okay if you put it correctly. They need to be put very lightly inside ear canal, not too deep, otherwise the tip will collapse and won't sound good. Sound is more detailed than anything I've ever heard. It doesn't sound fatiguing at all. Like i said, it sounds smooth. The azla sednafit light is the tip to go for. I've tried the spinfit cp100+ as well, but the sednafit light sounds the best. Thanks to mr pritam for helping me get the perfect iem for my taste.
Kudos to Pritam sir for the recommendation. A well balanced IEM with a high degree of musicality. My favourite IEM for when I simply want to lose myself in the music and enjoy the show.
Amazing what can be achieved with a single driver.
No Words for me to say about this IE 900 IEM. Even if I say more it will be very less. That much perfection in sound.
Firstly, I thank my new friend Pritam ( The Audio Store Co-Founder ). He helped me by asking about my taste in music and came up with the best for me. He was a polite person who never tried to sell anything until customer requirement needs it. Very honest in delivering the Info. Thank You, my friend, for the best recommendation.
IE 900 Wherever you search for review it will 9.9 Rating or 9.5 from Audiophiles. Any website or Video everyone says is the best. It is exactly the same as mentioned on sound.
Sennheiser has come with their experience on this IE 900 IEM. They are very well built material Aluminum when you put them in-ears feels like nothing was there. Such a good comfortable if you carry on your hands feel noting weight. The first impression of me was comfort.
Then I started playing with Iphoine 12 + 3.5 Jack + Apple Dongle Jack. It's a very simple setup not used any Dac/Amp then I started playing Dangreos By MJ. I can't really explain my experience with the first impression.
The instrumental part was Awsome!! Drums have kick bass. Guitar strings will make you simple :) Sound Stage will be like Auditorium. Vocals are a blessing Gift for this IEM. The bass is mindblowing and you keep repeating the song for that kick and experience.
You play anything it sounds exactly the same as how the musician thought to deliver the end of the listeners. That all will be delivered without any other expensive AMP DAC. That's the beauty of IE 900.
The big joke is it's a 7 MM Driver don't how they designed this IEM. It can be done only with the experience of 75 Years as a sound engineer like Sennheiser.
Great Job by Sennheiser Team. I really bow for their work.

from 5181 reviewsThe fitting and impact of sound quality and comfort is amazing I would love to buy more this kind of eartips
Most convenient

This was a gift for a friend of mine. The shipping took some time but when it reached them it was shipped the same day and after two days it was received. It came in perfect condition. I'll copy my friend's review below:
"This is most balanced IEM with a touch of warmth among everything out there. The Bass is just a bit much and with a 3db high-pass filter it became perfect. It doesn't get much better from this. The soundstage and imaging is decent and competes with +800$ stuff. The tuning, resolution and timbre is one of the best even under 2k. I'm very much in love with them. The comfort is pretty decent. I haven't got tired of them even after long hours."
The audio quality is very crisp and refreshing
The sound just amplified after using this with my kz castor pro IEMs....it is amazing.

Great product, strong magnet and holds the DAC snugly. Wish the 3M sticker was sold separately as well as already started to come off (user error).
the Detailed and balanced sound. then the design is so beautiful, the white version looks very good.
*What I liked the most:*
Clear sound at a volumes.
Good bass response, with focus on the sub-bass.
Tuning nozzles which make huge difference to the sound signature.
Good treble which is not harsh or sibilance.
Good soundstage & imaging performance.
Generous amount of ear tips to choose from.
High quality cable.
*Something that I didn't really like:*
Huge metal carrying case.
Ldac, hifi eq, durability, water proof rating
Quality

The amount you pay for this DAC is absolutely worth it. I'm using it with my PC, and I also have a Fiio KA13. It provides 32-bit 48000Hz audio output, and it's really good. I'm connecting it via a USB-C port and one extension cable (AGARO 3.5mm Aux Male to Female Extension Cable, Gold Plated). There’s no audio loss whatsoever.
The only minor issue is when you use it with a mobile device — the blue light can be a bit annoying. However, that's more of a personal preference. It also makes some noise with certain songs, but that's actually a known issue with the CS46L41 chip. There's no need to worry though; unless you've used a high-end DAC before, this will be more than enough for you.
Bass and clear vocals
😊
Excellent sound quality

After searching internet found this dac which has multiple input options and support 165*2 watts passive speakers and 350 watt passive subwoofer for future extension, tested with all input modes, bluetooth input feels a bit of low quality as it only supports sbc and aac codecs only, however if you want to use mobile via wired, alternative options 1. connect using Portronics Bridge Y USB 3.0 to Type C OTG Adaptor via USB A. 2. Use audiocular d08 cs-pro usb-c to 3.5 mm and 3.5 mm to rca input (cable creation brand). Optical input mode supports PCM (loss less stereo output) and Digital compress audio multichannel only) these are specific to Sony X-80J 65 inch
