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.

Great gift and lovely way to weave God's presence into daily life
Format: Imitation Leather
Love these prayers. I heard about the book from a podcast of Steve Cuss (or maybe Curtis Chang?). This book is a lovely and sometimes humorous way to weave God into the day. (My favorite-- a prayer for changing diapers! I sent this to my daughter in law).

Love Each of These Three Volumes - Most Excellent!
This is the third volume of Every Moment Holy and I already own and use regularly the previous two. So needless to say, I was excited to add this to my collection and it did not disappoint! Each of these books are written so beautifully and are unique and special. They have taught me better ways to pray and to look at prayer. They have encouraged me to better pray / how to pray with and for others. I use them daily!

Daily tasks in a wonderfully sacred light!
Wow! This is a wonderful way to remember that every moment is holy and should be honored. Well written! The illustrations are so good. I only wish there were twenty volumes instead of just 3!
