The ULTRASONE NAOS MICRO is an ultra-compact USB DAC for listeners who refuse to compromise on high-fidelity sound while on the move. Small enough for any pocket, powerful enough for demanding headphones, and designed to unlock significantly better sound from your smartphone, tablet, laptop, or desktop setup. 

At its core is a distinctive dual symmetrical architecture: two high-performance CS43131 audio converters work in parallel to create a precisely balanced signal path with excellent channel separation, low distortion, and impressive detail resolution. This concept is supported by the CT7601CR audio bridge controller, enabling reliable playback of advanced PCM and DSD formats. NAOS MICRO supports PCM up to 32-bit / 384 kHz and native DSD256 in UAC 2.0 mode. With switchable UAC 1.0 compatibility, it also offers broad support across a wide range of devices. Whether you are using a modern hi-res source, a mobile setup, or a device that requires UAC 1.0, NAOS MICRO adapts to your listening life. Its headphone outputs continue the symmetrical concept. A 3.5 mm single-ended stereo jack and a 4.4 mm balanced stereo connection give you flexible listening options for a wide range of headphones — from classic favorites to modern balanced models. 

The refined aluminum and glass housing combines premium design with true portability. Two configurable function buttons, a customizable RGB status indicator, selectable output levels, and USB bus power make NAOS MICRO intuitive, flexible, and easy to use every day. Compatible with Windows, macOS, Android, and iOS, and including a proprietary ASIO driver for ultra-low-latency playback, NAOS MICRO becomes a powerful sound upgrade for travel, work, home listening, and compact high-end setups.
