Wielenbach, 07. November 2017 – The Edition 15 sees ULTRASONE expanding its product range with a set of top-class open reference headphones. GTC driver technology is a completely new development that perfectly reproduces all frequency ranges, reproducing music with real transparency and precision. These are also the first open headphones to feature S-LogicEX® technology, which produces an outstandingly authentic stereo image and remarkably clear depth of sound. With high-quality materials such as American cherry wood for the ear cups, Merino leather for the headband and ear cushions with microvelour, the Edition 15 headphones also have a premium look and feel to match their high-end sound. Production of the Edition 15 is limited to 999 for an extra exclusive sound experience.

Edition 15: open reference headphones featuring our new GTC driver technology
The tonal highlight of the Edition 15 is the gold-titanium compound driver technology, an in-house development known as GTC for short. This technology combines a gold membrane with a titanium dome to produce unique sound qualities. Audio reproduction is taut and precise across the entire frequency range, from the lowest bass notes to the most delicate of trebles. With its new driver technology and open ear cup design, the Edition 15 delivers a pleasurable audiophile music experience that redefines the term “high-end”. And with high-quality LEMO connectors and a four-core cable, these headphones are fully ready for symmetrical operation.

S-LogicEX® for astonishing spatiality
The Edition 15 is the first set of open headphones to feature patented S-LogicEX® technology. Thanks to a special, fine-tuned driver arrangement, the sound is extremely natural, with a quality that is closer to playback on premium speakers than the typical headphone experience. The result is an authentic stereo image and vibrant depth of sound. Headphones with S-Logic® technology also require significantly lower sound pressure for the same perceived volume. This reduces listener fatigue, so even those longer listening sessions will be effortless.

Ear cups made from a wood used in instrument making
The ear cups are made from the exquisite wood of American cherry trees. By no means new to the world of music, this wood is extremely popular in instrument making. Many pianos and woodwind instruments are made from this high-grade wood – materials don’t get much more musical than this!

High-quality materials for the ultimate comfort
It isn’t just the wood used for the ear cups that meets the very highest standards in headphone production: the microvelour ear cushions and the Merino leather headband cushioning complete your listening pleasure. If the cushions get damaged at any point, they are easy to replace thanks to the ingenious magnet attachment. The stainless steel panels are one of the main attractions, their elegant design underlining the open construction and giving the Edition 15 a unique look.

Unique, limited-edition headphones from our production facilities
With just 999 sets available, the Edition 15 delivers a truly exclusive and enjoyable listening experience. Each set of headphones has its own serial number, making it a completely unique product. Furthermore, each Edition 15 has its own individual identity thanks to the natural materials used. The headphones are handmade at our production facilities on Lake Starnberg to ensure consummate listening pleasure.
