The M9 offers a plethora of features being an audio player that can transmit HWA/aptX/aptX HD/LDAC lossless Bluetooth codecs even when used as a USB DAC. It supports virtually all Bluetooth formats with its Bluetooth 4.2 such as 24-bit aptX HD, LDAC and HWA and has dual AK4490EN DACs that has high signal-to-noise ratio, great dynamic range and low distortion for a precise sound signature. Meanwhile, a A3P030 FPGA ensures that music is played back accurately no matter the sample rate with stabilization using digital clock signals and even decodes DSD64/128 in hardware. It also has an 8-layer HDI PCB to ensure excellent sound quality and a specially designed audio circuit with balanced and single-ended outputs.
Using M9 allows users to get their music from anywhere whenever they want with Wi-Fi, DLNA that allows for listening on computers and even have built-in streaming apps. Its battery lasts for 10 hours of playback but can go for 45 days when on standby mode. The M9 has both 3.5mm and 2.5mm balanced audio jacks and also supports CTIA (Android headsets) and iOS headsets. A nice addition is its RGB light indicator that changes color depending on the audio format being played and also indicates low battery with a red light. However, unlike most players, the M9 is capable of being used as an asynchronous USB DAC with both Macs and Windows PCs and can also acts as the computer’s Bluetooth transmitter.
The Android OS give users easy navigation with the carefully thought out user interface with some of the pre-installed apps being NetEase, Cloud Music, MOOV, Tidal and KKBOXS while it has a USB Type C connector which enables charging and file management when connected to other devices.

A player that does it all
When developing the M9, we at FiiO saw that there wasn't any one player that combined all of the functions people want. Was there a player that could transmit the HWA/aptX/aptX HD/LDAC lossless Bluetooth codecs, even when used as a USB DAC? What about something that also contained a highly optimized audio circuit for excellent sound quality? Did any players also give the user an experience worthy of a flagship, capable of many features including Wi-Fi music streaming all in a slick interface? We sought to change that with the M9 – which does all of this and more.
The M9 uses Bluetooth 4.2 and supports virtually all Bluetooth formats including the high-resolution ones for your ultimate listening pleasure, including: 24-bit aptX HD (also backwards compatible with aptX), LDAC, and HWA.
Bluetooth audio unleashed with full format support
As a Bluetooth transmitter: LDAC/aptX/aptX HD/SBC (both natively from the player and through USB DAC)
As a Bluetooth receiver: SBC (LDAC to be added with software updates)
The two AK4490EN DACs employed in the M9 feature a high signal-to-noise ratio, exceptional dynamic range, and low distortion – making for a precise yet exciting sound signature.
Dual AK4490EN DACs for superb decoding performance
Built-in dedicated FPGA with DSD128 hardware decoding
Inside the M9 is a high-performance A3P030 FPGA, responsible for ensuring your music (whatever sample rate) is played back accurately by stabilizing digital clock signals. The FPGA also decodes DSD64/128 in hardware, which the M9 supports in ISO/DFF/DSF formats.
Eight-layer HDI PCB ensures excellent sound quality
For the first time, in the M9 FiiO uses an eight-layer HDI (High Density Interconnect) PCB with a thickness of only 0.08mm. While the M9 PCB is more complex than the one in the M7, it also allows more components to be integrated into a smaller space, leading to a smaller PCB and a smaller device overall. Combined with the fact that the M9 PCB is L-shaped, similar to modern smartphones, and you have a recipe for outstanding sound quality.
The TI OPA1612 is used as the LPF, while the TI OPA1622 serves as the current buffer. To achieve single-ended and balanced output, there are two OPA1622 op-amps used that provide up to 77mW* of power under a 300Ω load.
