Dedicated Professional Audio Design
Utilizing TI's high quality CM5242, the all new X1 gets higher SNR and supports full differential line output to achieve balanced line-out function. With dedicated LPF and op amp, we have optimized power architecture design and circuit to further improve sound quality, resulting in better low-frequency quality and depth. The new X1 supports all major lossless music formats: APE, FLAC, WAV, WMA, and ALAC, at up to 192kHz/32bit.

Improved Functionality
The headphone output is switchable to line-out, allow the X1 to be used as audio source to your amplifier. Deep-sleep standby enables instant-on playback, with stand-by power for as long as 15 days from a full charge. Music on demand, at a moment's notice. In-line remote control support for most headphones (not compatible with Apple Earpods)
