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 toy for moderately destructive dogs
Color: Dragon
My dog LOVES this toy. It's not hard to see why: it has just about everything a dog could want in a soft toy. There are ropes that move around, a squeaker, crinkly wings, and different textures of fabric. It's not extremely durable--I've had to sew up one busted seam within a month or so--and you will likely have to re-knot the ropes and pull them back through the holes, but if your dog is only moderately destructive, they will enjoy this. I'd buy another.

Dog Obsessed -- Toy a Mess
Color: Squirrel
The dog was OBSESSED. Truly loved this toy, but he ripped the little pockets really easily. While he still wanted to play with it, it was a little disappointing.

Cute toy
Color: Squirrel
My dog loved it! Looks just like the pics. Durable for most dogs I’m sure. My little dog can destroy anything though lol! Didn’t get to use the treat part cause he destroyed it but looks like a neat concept

Creative and well made!
Color: Squirrel
This is a great dog toy, durable, creative, and it kept my dogs busy and very, very interested. It's challenging enough, but not frustrating. Great for tug of war, too!

Looks like fun but NO
Was so excited to get this and slow my girls down eating their treats and engage them in play. How big do the treats have to be? Because I had to scoop wet gross chewed up treats out of each pocket, vacuum, and put them in the washing machine AFTER my girls abandoned them with the treats still in the pockets. GREAT IDEA but not functional. Agressive chewers would have destroyed the toy the first time. SO DISAPPOINTED
