Sennheiser IE 900 Audiophile In-Ear Monitor Headphone

 The precision-manufactured aluminium housing of the IE 900 faithfully protects the dynamic TrueResponse transducers at the heart of Sennheiser’s innovative X3R technology.

In addition to outstanding sound, audiophiles appreciate durable products that are made to last. Here as well, the IE 900 excels.

Gold-plated Fidelity+ MMCX connectors ensure perfect contact. Each termination is seated within a recessed, 4.8 mm-wide socket below the surface of the housing, providing strain relief. The cables themselves are para-aramid reinforced to withstand many thousands of bend cycles. But they don’t have to when protected in the included serialized case. Connect to practically any digital audio source with the 3.5 mm stereo plug including headphone amps, laptops, and audio interfaces. Each pair of IE 900s also includes symmetrical 2.5 mm and 4.4 mm cables for plugging directly into hi-fi components with balanced outputs. Because when you’re looking for the most natural and immersive sound, every detail matters.

Experience peak German audio engineering

The precision-manufactured aluminium housing of the IE 900 faithfully protects the dynamic TrueResponse transducers at the heart of Sennheiser’s innovative X3R technology.

The IE 900 reveals the true potential of any recording. If it’s a masterpiece, you’ll hear it. Brilliant, sparkling treble — with no trace of sibilance.

A single dynamic driver only — of the highest quality, of course.


In developing the IE 900, Sennheiser faced a fundamental choice. The inherent compromises multi-driver systems require (phase issues and the resulting distortion in overlapping frequency bands) made the decision easy. There would be a single dynamic driver only — of the highest quality, of course. To get exactly the sound they were looking for, they designed a sophisticated system of three Helmholtz resonators — a crucial element in the X3R technology - milled right into the solid aluminium housing of each earphone. These tiny channels eliminate resonance peaks which can colour the sound signature and alter the feel of your music. In addition, a complex structure in the nozzle of each earphone — the Vortex — swirls acoustic energy in these frequency bands to smooth out peaks.

Smash or Pass? ….Smash.
The smash phone mount did the trick. There was never a good or convenient place to put my phone in the 4-runner. This piece of kit fixed the issue nicely. Fits in the little storage spot tightly with a spring loaded friction mount. The hardware to manipulate the holder so you can customize your preference is made of metal so it will be durable and stable and bc you can change it around to fit your needs it has a lot of functionality. A little pricey but a good add-on for the rig.

Get the stubby, not the standard
This is a very nice mount. I strongly recommend the stubby version over the standard, mostly because you can move the phone holder around to help keep it visible and out of the way. As a taller guy, the standard mount would be hitting my knee when I get in the vehicle, but the stubby mount allows me to move it further towards the passenger side, which also keeps my cup holder usable.

Perfect fit attachment!
This product is built very strong and fits perfectly into the small cubby in the lower middle dash of my 2018 4Runner. It holds my iphone tightly but is easy to remove. 100% satisfied with this purchase.
