Better conversion on the go
Have you ever been irritated because you were unable to experience your favourite music on your smartphone in the sound quality you wanted? With NAOS, Ultrasone is ending this annoyance. The conversion and amplification of headphone signals will no longer be undertaken by components in smartphones and tablets, which are often very cheap, but instead by a high-quality device: NAOS. When used with award-winning Ultrasone headphones, it gives you the excellent sound you expect, even when mobile.
Good sound really can be this compact
NAOS’s dimensions are extraordinary: 46 millimetres long, 18 millimetres wide and 6 millimetres deep – smaller than a match box! Weighing just 6 grams, NAOS is hardly noticeable. In contrast, its audio properties make it clearly noticeable, as it combines a high-quality digital to analogue converter with a headphone amplifier of the best possible quality and turns mobile music consumption into a special treat.
Hi-res in your pocket
The DAC in the NAOS allows source material to be converted up to a resolution of 192 kHz and a word width of 24 bits. In this way, not only do MP3 files and uncompressed signals in CD-quality benefit from the NAOS’s precise conversion, but high-resolution streaming services can also be played in all of their glory. The NAOS enables lossless enjoyment and studio-quality music on a smartphone.
After conversion, the now-analogue signal runs through a high-performance amplifier that is optimised for operation with a wide range of headphones. Whether a circumaural full-size model or small in-ear headphones, the NAOS will produce an optimal signal at the 3.5mm jack output. A headphone amplifier with the weight of a credit card! Of course, the NAOS can also be used with active speakers or upstream from a power amplifier, to use the high-quality converted signal as a source for speaker playback.
Connected to everything
In addition to the sound quality of its components, NAOS will also impress with its extensive connectivity. Whether mobile or stationary, NAOS works with smartphones, tablets, notebooks and desktop computers. To this end, it comes with cables for micro USB, USB C, Lightning and USB A. NAOS uses the connection not only to transfer data, but the compact DAC also draws its power using the same cable, so no additional power supply is necessary. NAOS works with iOS, Mac OS, Android (USB OTG function) and Windows (driver installation). Laptop, smartphone, desktop PC or tablet – NAOS is always a match.
NAOS and the corresponding cables for micro-USB, USB-A, USB-C and Lightning connections can be stored together in the elegant carrying case. This way, nothing gets lost and both the converter and accessories are always close at hand.
"Not only is the NAOS tailor made for portability, Ultrasone has gone the extra mile to make the device friendly to any platform be it Apple, Android, PC, high quality source, or low quality source. This catch-all use it anywhere, anyhow mentality is further bolstered by the number of attachment components that comes with the product in its simple black carrying case.
