Present in the M15 is FiiO’s self-developed 3rd generation FPGA with more advanced algorithms, more accurate clocks, and even further reduced jitter.

June 17, 2022 - In this article we review the $1,499 USD FiiO M15. It has the best dual DAC of the market on paper, but does it deliver? Now on Headfonia!

October 12, 2023 - The FiiO M15 is a new flagship digital media player, (DAP), featuring a dual AK4499EQ DACs, MQA decoding, and LDAC Bluetooth capability. It is priced at $1,299.99.

The new M15S starts a new chapter in the FiiO high-end, sharing the same technologies as the portable desktop-grade M17 player and the portable desktop-grade amp Q7 that give you desktop-level performance in a portable package – including desktop mode, dual power supply modes, and five gain ...

April 24, 2023 - Sure, I couldn’t reach the same level of resolution, found on the FiiO M17, but considering the price, and more importantly the size, that’s not a real flaw in my opinion. Don’t get me wrong, sound-wise, if not as impressive as the M17 this new M15S remains a few steps above the M11 Plus, and the M15, thanks to its large power reserve: deep bass, smooth mids, excellent layering, it’s an amazing portable source in and out – a real upgrade from the M11S and M11 Plus, sonically speaking.

In truth, the M15 audio quality matched the much cheaper Astell & Kern SR25, but the better amplifier in the M15 made it a winner with inefficient headphones. I liked the bigger, high-quality screen, and I also liked being able to turn off the Android OS and listen to the M15 in a ‘pure’ audio mode that was designed only for the playback of music. ...

What was quite unusual even for FiiO is that instead of just showing it to the world and telling everyone you will need to wait for another 6 months before you can buy it, it was available right away with preorders starting the next day. I still remember that I waited for more than 6 months for a M11 PRO after its announcement and I’m glad that didn’t happen with M15...

FiiO M15 adopts 5.15’’ HD full touch screen(Corning Gorilla Glass),supports 5GHz/2.4GHz WiFi,MQA,2.5mm/3.5mm/4.4mm headphone outputs,QC 2.0 fast charge,USB DAC.

January 4, 2024 - The M15S internal setup is quite different this time around and we have the legacy of the M17 to thank for that. ... The FiiO M15S is a mid-to-high-end open Android 10-based portable audio player and an update on the original M15 DAP.

January 29, 2020 - My Video Review: Who would thought that at their flagship year from its inception, FiiO would announce at their Winter Launch Event in an One More Thing stunt, their highest performance and highly anticipated M15 DAP. What was quite unusual even for FiiO is that instead of just showing it to ...

The M15 had to surpass the already excellent M11 (and the M11 Pro after that) in every conceivable way so to do that FiiO equipped it with not 1 but 2 AK4499EQ switched resistor DACs by Asahi Kasei (768KHz/32-bit/DSD512 native/140dB SNR) which they successfully paired with the Exynos 7872 hexa-core processor by Samsung (features two A73 cores clocked at 2GHz, four A53 cores clocked at 1.6GHz, 3GB LPDDR3 RAM and 64GB flash memory), the XUF208 USB chip by XMOS (768KHz/DSD512 - 384KHz/DSD128 for USB audio) and the CSR8675 v5.0 bluetooth chip by Qualcomm (supports the SBC/aptX/aptX-HD/LDAC/HWA audio codecs and features their Kalimba DSP).

The full, uncut desktop ES9038PRO DAC chip with eight independent D/A converters is employed in the M15S.Each channel uses four D/A converters in parallel to form a fully differential output, for a truly rich and highly resolving sound. Audio data is passed through a FiiO-developed 4th-gen FPGA with phase-locked loop technology, which works together with two custom Japanese NDK femtosecond crystal oscillators to provide a high-precision and low jitter unified clock source for the entire audio architecture.

February 16, 2022 - The FiiO M15 is the top of the line flagship player from FiiO, at least for now. It’s similar in design to the less expensive M11 and M11 Pro, but those players can’t power hard-to-drive headphones.
