German company Ultrasone AG has come up with some pretty impressive audiophile-oriented gear over time, and now, they're back with yet another very cool offering in the field of high-end audio, namely the first open back special edition headphone – Edition 10, that's all about luxury, crisp audio and style, featuring Zebrano wood ear cup inlays, Ethiopian sheepskin leather ear cup pads, Titanium plated drivers and Kevlar coated cables and, not to mention that only a limited number of 2010 units will be available.

Drawing inspiration from natural forms, the Edition 10’s ear cups feature high levels of air permeability through the grills, high specific torsion strength and extremely low resonance, all in a lightweight design.

The outer ear cup is finished with galvanic Ruthenium plating and with a Zebrano wood inlay, which is coated with eight layers of clear lacquer for protection.

The Edition 10’s inner ear cup, as well as the head-pad, is adorned with reddish brown Ethiopian sheepskin, a type of leather that's known for being the most supple leather available, achieving a very good level of comfort and sound isolation.

The drivers selected for the Edition 10 have been specially tuned for open back headphones, the Titanium-plated 40mm drivers being designed with a 10% more powerful magnet for enhanced sound pressure levels.

Each set of drivers have been individually paired with a tolerance of +/- 0.4, while Ultrasone has also incorporated silver-plated OFC 99.99% pure copper wires and utilized Kevlar as the casing, achieving increased current flow, improved flexibility and lower overall weight.

In addition, the Edition 10 is designed to be balanced input ready, so audiophiles who wish to implement a balanced cable configuration do not have to change the entire wire, rather connect XLR connectors instead of the 6.3mm connector.

Ultrasone’s latest headphones employ S-Logic Plus technology, resulting in an impartial acoustic feeling that affords the listener a spacious tonal perception.

This gives users the advantage of wearing Ultrasone headphones for many hours without their ears hurting.

Ultrasone’s newest headphones also contain MU-Metal shielding (ULE technology) that reduce the amount of radiation directed to the listener by up to 98%, as compared to conventional headphones.

Other important features worth mentioning include the frequency range (5 - 45000 Hz), the impedance (32 Ohm) and the sound pressure level (99 dB).

Since we're talking about audiophile-grade headphones here (and also a limited-edition, luxury item), it should come as no surprise that the Ultrasone Edition 10 are extremely expensive, relatively few and passionate music lovers affording to pay around $2,749 for a pair.
