High End Partnership

In cooperation with Auris Audio, well known European High End company, EarMen designs a Sparrow, High quality DAC and amp, with impressive characteristics.
Designed to process digital sound of up to High-Resolution Audio quality into analog for greater detail, clarity, and precision, Sparrow delivers audio close to the original studio recording.

Designed and Built in Europe

Sparrow’s great characteristics are available by using the best components and materials.
The vast majority of the total production cost of Earmen - chassis, boards, transformers, assembly, etc - stays local. Our chassis are made minutes from our facility. Our PCBs are done in HCP. Yes, some components are made in China, but there's some give and take at this price point.

Featuring Audiophile SABRE DAC

Sparrow is powered by ES9281PRO, the flagship of the ESS line, which can provide best-in-class audio performance at 124 dB DNR and -112 Total Harmonic Distortion plus Noise (THD+N). The ES9281PRO is the first USB product that offers an integrated hardware MQA (Master Quality Authenticated) renderer that makes MQA playback easy and cost-efficient. The encoding process folds extra information into the signal that can be recovered later. The ES9281PRO automatically detects the MQA stream and engage the rendering. The entire process requires no additional design work.

Low-Noise Design

Using a Super LOW ESR tantalum capacitors, high grade components in power-supply design and 4 layer golden plated PCB technology from PC and smart phone industry, Sparrow reduces the noise to minimum. This will improve super fine details especially in Hi-Res files where you can feel and hear the difference.

Gold plated PCB

Sparrow’s PCB (Printed Circuit Board) is 4 layer gold-plated, which is unmatched in terms of quality and performance. Gold plated PCB guarantees the minimal loss of sound quality.
Earmen manufacture this through CNC drilling and pattern plating.

Size and Design

Sparrow is housed in a light-weight, but robust aluminum enclosure, which protects audio signal from the interference. The aluminum structure is created via CNC milling.
If you are using your phone as your source of music, small and lightweight device is key. From a design perspective, smooth rounded edges enable it to feel more like an integral part of the cable without catching or snagging on anything.

Easy to use

Built-in adaptive drive, there is no need to manually install the driver. The connection can be used directly, easily adapting smartphone to professional audio equipment.
