FiiO
FiiO M15 Portable Music Player
The M15 is FiiO’s flagship digital audio player (DAP). Featuring a top-of-the-line digital-to-analog converter (DAC), MQA support, Japanese femto crystals, dual-band WiFi, and Qualcomm’s flagship bluetooth chip, the M15 packs a home theater system worth of features into a stylish handheld.
Blistering Performance
The M15 features the Samsung Exynos 7872, a 2GHz, hexa-core processor that delivers lag-proof, frustration-free file transfers, track playback, and operation.
The Bleeding Edge
The M15 features not one but two of AKM’s flagship DAC, the AK4499EQ. Capable of supporting sample rates up to 32-bit/768kHz and native DSD512, this 4-channel, 32-bit DAC is at the absolute bleeding edge of decoder technology.
Silent Sonic Backdrop
With a signal-to-noise ratio (SNR) of 122dB, distortion as low as 0.0004%, and a noise floor as low as 2.1µV, the M15 presents your music on a completely silent sonic backdrop. No noise, no distortion. Nothing but music, plain and simple.
All Headphones Welcome
Whether you rock a pair of low-impedance IEMs or power-hungry planar magnetics, the M15 can drive them. With a balanced output of 280mW at 300Ω, it can handle any pair of phones you’ve got.
MQA-Ready
Would you die a little if we told you that MP3 files deliver just 10% of original studio recordings? That’s one-tenth of the nuance, depth, and richness that the artist intended for you to hear. MQA (Master Quality Authenticated) files, on the other hand, deliver the full, uncompressed sound of the original master recordings in all their richness. The M15 supports this technology, delivering the best version of the music you love.
Jitter Eliminator
Jitter is this generation’s disc skip--it’s aggravating, intrusive, and could potentially ruin a listening experience. Okay, maybe it’s not as intrusive as disc skip, but it should be avoided at all costs. The M15 uses two custom Japanese femtosecond crystals, correcting drift in the signal timing to as low as -140Bc/Hz @ 1kHz. You can kiss jitter goodbye.
Wireless Wonder
Dual-band WiFi not only ensures better signal strength and stabler connections; by using a different band it avoids interference with Bluetooth altogether. WiFi and Qualcomm’s flagship Bluetooth chip team up to allow the M15 to work as a Bluetooth player/amp and interact with any other DLNA devices you own.
A Do-Whatever-You-Want Customizable Button
The M15 features a mappable multifunction button, allowing you to customize the M15 to your preferences. Want to switch digital filters with one click? Or change the EQ? Or enter USB DAC mode? This button’s all yours.
