A Revolution without Equal

Sleek, minimalist, solid build
The E17K inherits the brushed metal crafting of the E17, but with fewer buttons in front and a thinner profile for a sleeker look.

Multifunctional wheel
Utilizing an all-new, unique multifunctional wheel, responding to both turns and presses, the E17K provides intuitive, agile control in one spot in place of several buttons on the E17.

USB audio decoding
Utilizing the SA9027 USB receiver, the E17K may be used as an external sound card for computers, supporting up to 96 kHz/32 bit, and supporting DSD decoding (*with ASIO driver and SACD plugin).

Uncompromising sound
The E17K utilizes TI's all-new PCM5102, which possesses higher S/N ratio, lower distortion and more linear digital-analog conversion characteristics. Also utilizing TI's flagship OPA1622 as low-pass filter, and the OPA1642+LMH6643 in a OP+BUF architecture usually only seen in high-end units.

Complete connectivity
The E17K expands on the industry-standard Micro-USB socket to not only provide charging and data exchange connectivity, but also to dock with FiiO's future desktop products. Also come with coaxial digital input supporting up to 192 kHz/24 bit PCM input (3.5mm to coaxial converter plug included), and dual-function line in/line out port for maximum convenience and operational value for money.
