Since the battery operates at a higher voltage, the analog circuit maintains strong output fluctuation and clean performance even when you're not sitting at your desk. Charging is fast—about two hours with PD3.0 fast charging—so you can keep it ready for spontaneous listening at any time.FiiO's discrete R2R DAC for natural soundAt the heart of the DM15R2R is Fiio's proprietary R2R DAC. Instead of a conventional delta-sigma architecture, it uses a resistor ladder to convert digital data into analog waveforms. The result is a smoother, more organic reproduction that many listeners prefer. The player also features low noise and low distortion—THD+N below 0.030% at 1 kHz and a signal-to-noise ratio of at least 112 dB—so quiet passages remain quiet and dynamic passages remain powerful.Balanced and unbalanced outputs to suit your listening styleYou get both a 3.5 mm single-ended and a 4.4 mm fully balanced headphone output, each supported by its own amplification. The balanced connection offers up to 1150 mW per channel in desktop mode, while the single-ended connection offers easier handling for efficient models.The line-out options are just as flexible, as both the 3.5 mm and 4.4 mm outputs are designed for use with amplifiers or active speakers.Bluetooth when you want to go wirelessIf you want to free yourself from cables, the DM15R2R can transmit Bluetooth signals to your favorite wireless headphones or speakers. Supported codecs include SBC, aptX, aptX-HD, aptX-LL, and aptX-Adaptive. This allows you to easily listen to your discs without being tied to a cable. Useful when cooking, walking around the living room, or in any situation where cables can get in the way.ESP anti-vibration support for more stable playbackThe ESP switch stabilizes playback when the player moves or shifts. It reduces the likelihood of dropouts when you walk or carry the device from room to room. Once you've settled down at your desk or on the couch, you can leave it on or off. The player will read the disc reliably in either case.An infrared remote control for touchless controlIf the DM15R2R is on the other side of the room, you can use the included infrared remote control to control basic transport functions without having to pick up the device. Skip tracks, pause, stop, or adjust output modes while remaining seated. It may seem like a small thing, but it makes for a more relaxed listening experience—especially when the player is paired with speakers or an amplifier.Special laser lens for CD players for stable disc readingThe DM13 has been on the market for over a year. Its disc reading performance has been significantly improved through several upgrades and optimizations. Building on this, the DM15R2R has been further developed, with a lot of investment in adapting to some disc shapes and introducing a self-resetting steel button design to ensure smoother disc insertion/removal and prevent damage to the discs.*The disc reading capability of the DM15R2R is equivalent to the new firmware version of the DM13.**Due to the limitations of the portable motion structure, perfect reading of all CDs cannot be guaranteed. Firmware upgrades will be implemented in the future to continuously optimize disc reading performance.***Due to differences in motion, disc material, and recording environment, frame skipping when reading a small number of high-capacity CDs is a normal phenomenon.Supports USB audio capture functionAppreciate the moving melodiesSupports capture while listening to music, allowing favorite CDs to be saved in WAV format on mobile storage devices and the moving melodies to be shared with friends.*Only supports mobile storage devices in FAT32 format.**Only supports ripping audio in CDDA format.
