GCIG X1 Portable USB DAC Headphone Amplifier, Grey, (Pack of 5 pcs)

The heart of X1 is the 24-bit ESS Sabre conversion chip, a high-performance solution that's typically found in better CD and Blu-ray Disc players.

X1 can accept audio and music files ranging from MP3s and CD-standard 16-bit/44kHz to native 24-bit/96kHz high-resolution, regardless of music file format. If your computer's software can recognize and play a format, X1 will make it sound its best.
