Sennheiser - IE 900

Sennheiser IE 900

peak German audio engineeringThe Sennheiser IE 900 in-ear headphones feature precision-manufactured aluminum housing to faithfully protect the dynamic TrueResponse transducers, found at the core of Sennheiser’s innovative X3R technology. High-fidelity recordings are pieces of art and should be heard in every detail, the IE 900 displays the full potential of every recording. If it’s a masterpiece, you’ll hear it with impressive, sparkling trebleand no trace of sibilance.

Powerful lows free from muddy mids and the ability to resolve fine detail, alongside warmth and comfort for extended sessions. All these qualities come from inspired feats of engineering. For example, Sennheiser’s trusted 7 mm transducer has made it just that much better for the IE 900. All-new X3R triple-chamber absorber is also technology milled right into the solid aluminum core with its downstream acoustic vortex. Together, these innovations offer a unique level of balance and transparency without compromise.

A New Level of Clarity

Sennheiser IE 900

highest quality onlyWhen developing the IE 900, Sennheiser faced a fundamental choice and the inherent compromises multi-driver systems require (phase issues and the resulting distortion in overlapping frequency bands) made it a no brainer. There would be a single dynamic driver only made of the highest quality.

To get exactly the sound required, Sennheiser designed a complex system of three Helmholtz resonators, a vital element in the X3R technology milled right into the solid aluminum housing of each earphone. These small channels eliminate resonance peaks which can colour the sound signature and shape 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.

Made To Last

Sennheiser IE 900

Durable connectionsGold-plated Fidelity+ MMCX connectors offer 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 over thousands of bend cycles, although they won’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 comes with symmetrical 2.5 mm and 4.4 mm cables for plugging directly into hi-fi components with balanced outputs. When you’re looking for the most natural and immersive sound, every detail matters.

The Sound of Manufacturing Expertise

Sennheiser IE 900

acoustic back-volumeThe aim here was to achieve a transparent sound with no distracting peaks or troughs. One thing this requires is clear separation of lows and mids. To ensure accuracy across this frequency band, Sennheiser used what is known as an acoustic back volume. It’s a small chamber within a chamber we have tuned to manage the slope and amplitude of the bass lift. The way the back volume helps provide such a clear and natural sound signature is by controlling the direction and overall volume of air as it moves through the transducer system. What you hear is a nicely disciplined bass and mid-range experience. Unpleasant resonances and listening fatigue are no longer presentt.

Sennheiser IE 900

state-of-the-artIn the same facility that builds the revered HD 800S, HD 820, HD 650 and HD 600. The use of aluminum was a clear choice: well-suited to high-precision milling, it also looks great and is a long-lasting home for the electro-acoustic components. A five-axis CNC machine precision cuts each housing individually from a single block of aluminum. Once anodized, the housing is highly resistant to wear and corrosion, music to the ears of any frequent listener. The drivers in each pair of IE 900s are matched during the automated manufacturing process to practically eliminate variance. Resulting in a true work of art.

A Precise Fit For Precise Sound

Sennheiser IE 900

Comfort is keyWorking musicians rely on high-quality, form fitting earphones known as personal monitoring systems. Here we have the added privilege of enjoying perfect live sound, no longer exclusive to the performers of the world. Sennheiser took the comfort and secure fit of these professional solutions as inspiration for the IE 900. You can now enjoy a fit and quality that rival that experienced by the artists who create your music.

Included with the IE 900 are silicone ear adapters and three elastic foam ear adapter sets in three different sizes. These adapt to the natural shape of your ear for a tailored fit. When an amazing piece of music is spoiled by a recurring bass note that happens to match the resonant frequency of your loudspeakers or headphones, or rough treble sibilance that makes longer sessions uncomfortable, these obvious deficiencies become unthinkable with the IE 900. All you will hear is precisely what the artist intended. They’re perfect at your desk, on a train, or taking a walk through the woods. Never have a listening session spoiled by your earphones again.

Reference DAC AMP
Qudelix - Q5K

Qudelix Q5K

ESS ES9219C DACThe experts at Qudelix wanted the device to work as a universal DAC/AMP for both high-sensitivity IEMs as well as high-impedance open-back headphones. Qudelix wanted it simple, small, yet but powerful. In addition to the sound quality and the maximum output power, they also needed to consider the battery time as well, concerning the nature of the device.

Qudelix’s engineers tried many DACs and Amplifier ICs and found ESS9219C is the best option for their goal. Besides the sound quality, the primary advantage of ESS9219C is that the built-in amplifier delivers the maximum output voltage up to 2V RMS. Furthermore, it supports the 1V RMS option at the same sound quality to save power consumption.

For high-sensitivity IEMs, the amplifier noise figure is the most important. The high-sensitivity IEM is so sensitive that it translates every electrical noise or thermal drift into audible acoustic sound, usually white noise.

On the other hand, the high-impedance headphones require a higher power amplifier. Those headphones usually have low sensitivity, and they are free from the white noise affected by the amplifier noise characteristics. Instead, they need higher power from the amplifier output to deliver enough loudness and headroom.

QX-Over Earphones

Qudelix Q5K

QX-OverQX-Over is an active digital crossover with Qudelix's proprietary DSP technology. Qudelix-Q5K automatically detects QX-Over Earphones, processes the stereo input, and outputs Stereo Low and High band independently to earphones units through 4-channel DAC/AMP.

Multi-Driver vs. Single-DriverEarphones and Speakers can be designed with a single speaker unit or multiple speaker units. It depends on, but practically, a single driver unit can hardly reproduce the entire audio details precisely over the whole frequency range. Real-world audio is not like a single-tone but complex waves over the frequency range.

Audio Codecs

Qudelix Q5K

full support for all codecsThe Qudelix-Q5K is the world's 1st Bluetooth DAC/AMP to support all the latest codec technologies, including aptX Adaptive, LDAC, AAC, aptX HD, aptX, and SBC. aptX Adaptive is Qualcomm next generation dynamically adjustable audio codec designed to deliver robust, low-latency, low-bit rate, high quality wireless audio.
