FiiO Media Player FX1221 BLACK REFURB X1 2ndGen Portable High-Res Lossless MusicPlayer

Comprehensive improvement of hand feel starting from the touch wheel
By studying and comparing dozens of designs and through hundreds of experiments and tests, we have finally developed the unique FiiO touch wheel with higher sensitivity, better anti-interference, enhanced reliability and longer service life.

Wireless Bluetooth 4.0 allowing to enjoy music easily
The Bluetooth 4.0 system based on F1C81 chip set allows you to easily enjoy the music with reduced latency and high sound quality.

Getting rid of the wire to achieve two functions
Two-way transmission allows it to receive Bluetooth signal while sending Bluetooth signal.
(RM1 can be used at the same time when Bluetooth headphone or Bluetooth speaker is on.)

Not limited by wire
Being not restricted during exercise, you may have a good sweat while enjoying wireless music.

On-board music accompanying you on the way
In-vehicle mode provides a perfect link between music and vehicle audio system, which has greatly improved the acoustic quality of vehicle audio system and let you enjoy music on the way.
(When vehicle engine is ignited, X1 is turned on too. When you shut down the engine, X1 stops immediately. There are no tedious manual operations anymore.)

Dedicated professional high quality DAC chip
Utilizing Texas Instruments high quality CM5242, the all new X1 gets higher signal-to-noise ratio and supports full differential line output to achieve balanced line output function, as compared with PCM5142 of last generation.

Further optimized architecture
With dedicated LPF and operational amplifier, we have optimized design of power architecture and circuit at the same time to further improve sound quality of the all new X1, making better low-frequency and depth.
