Optimized sound through sophisticated tuning by audio expert

Opus#1s is based on Android operation systems compatible with the ARM Cortex-A9, up to 1.4GHz with the Quad-Core CPU DDR3 1GB to express the best possible sound, providing bit to bit decoding and supporting wide variety of audio formats.

Opus#1s maximizes the advantages of the CS43198 DAC performance while retaining the sound of the audio-opus series praised by users, enhancing ultra low range and high range sound compared to the existing Opus#1 .

You can enjoy more dynamic sound.

OPUS#1S Hi-Res Portable Digital Audio Player with FREE Leather Case

Best DAP I've ever had.

To me this is a very good player. It sounds very clear and has plenty of power. The only down side is the battery only last 9 or 10 hours.
