Although many mobile music enthusiasts are using true wireless headphones, enthusiasts on the move are more inclined to choose the high fidelity provided by wired headphones. The German audio brand Sennheiser’s $1,500 IE 900 flagship headphones is aimed at these listeners.
Sennheiser said that through IE 900, the engineering team successfully released the potential of the 7mm system. Sennheiser IE 900’s affinity for details is eye-catching. The clean and balanced sound characteristics ensure that the original recording is restored. IE 900 broke the limit of people’s earphone listening experience and deservedly become the top product among similar products.
The outer shell of each Sennheiser IE 900 headphone is made by a single piece of aluminum milling by a professional team from Wedemark in Germany, and it is equipped with a new 7mm X3R system. Sennheiser specifically uses a single drive structure. , To avoid multi-drive problems, such as phase inconsistency and unnecessary distortion.
The housing is also equipped with the company’s three-chamber absorption system, which uses three Helmholtz chambers and a downstream acoustic vortex to counter the so-called masking effect, that is, if a lower frequency sound is emitted at the same time, the human ear cannot hear it. To low-volume high-frequency sound.
The X3R system enables listeners to hear more details in the music, which is exactly the purpose of audiophiles. The three resonant cavities make the high frequency response in the 6.5 to 10 kilohertz region smoother and reduce the so-called masking effect. This means that users can better hear frequency details above 11 kHz.
In order to ensure quality control and optimal performance, Sennheiser engineers are said to even pair each set of left and right earphones manually. The company also includes a newly developed diaphragm to provide internal damping. The total harmonic distortion figure is 0.05% at 94dB and 1 kHz. The headphones has a wide frequency response from 5Hz to 48kHz and a sound pressure level of 123dB. The impedance is 16Ω.
Three sizes of adjustable earhooks, x silicone and memory foam eartips ensure comfortable and safe wearing. The earphones are equipped with unbalanced 3.5mm cables and balanced 2.5mm and 4.4mm cables, which can be used with high-end portable audio The equipment is compatible. The Sennheiser IE 900 headphones is now available for pre-order at a price of US$1299.95 and is expected to start shipping next month.
