- Fully-Differential 24-Bit R2R DAC Array - FiiO has featured its newly developed four-channel fully differential 24-bit R2R resistor array on the K11 R2R. It consists of 48 resistors per channel, a total of 192 high-precision ultra-thin film resistors with 0.1% accuracy and low-temperature drift between the four channels. It promises clean and crisp output with dark background thanks to the specially developed audio circuit architecture.
- NOS/OS Dual Operating Modes - FiiO K11 R2R has NOS(Non-Oversampling) and OS(Oversampling) dual operating modes. These are freely switchable and offer dual sound characteristics with the device. The NOS mode maintains the original sampling rate while signal processing while the OS mode oversamples all the signals to 384kHz for processing. NOS mode results in more musical presentation while the OS mode delivers more details and clarity.
- Powerful Amp Section - FiiO has equipped the K11 R2R with professionally designed amp circuitry. It consists of Ti OPA1642 as Low-Pass filters and then dual SGM8262 Professional-grade operational amplifiers. The K11 R2R has an output power rating of up to 1300mWx2, which is adequate enough to drive demanding headphones with ease. It has three-level gain modes for easy pairing with sensitive as well as high-power requiring gear. The K11 R2R also adopts NJW1195A precise digital volume chipset for precise volume adjustment with low distortion between the channels.
- Dual Headphone Output Ports - FiiO K11 R2R houses dual headphone output ports. It consists of a single-ended 6.35mm port and a balanced 4.4mm output port. You can easily pair different IEMs and headphones with the K11 R2R and enjoy high-resolution music to all its glory.
- True High-Resolution Audio Signal Processing - FiiO K11 R2R supports decoding for high-resolution audio signals. It has full support for PCM and DSD signal processing supporting up to 32-bit/384kHz PCM and DSD256 audio signals. DSD256 requires the DSD output mode to be set to native. It is internally converted into PCM for R2R signal processing.
- A Brand-New Processor That Surpasses Competing Products — Qualcomm Snapdragon 680 Built on a 6nm process, it delivers superior performance and enhanced power efficiency. With 4GB+64GB storage and Android 13, it ensures smooth and seamless operation for all major music apps.
- Patented Desktop Mode with 950mW High Power Output: When Desktop Mode is activated, the M21 operates entirely on external power, with the built-in battery neither charging nor discharging—effectively extending battery lifespan.

- [PCM 384kHz/32bit, DSD256] Supports 32bit/384kHz PCM despite its tiny size, it is capable of highly-detailed sound.
- [3.5+4.4 dual outputs] After repeatedly adjusted design, it finally managed to fit two headphone outputs in the compact dongle, marking true progress in packaging capabilities.
- [App connectivity] Supports being controlled with the FIIO Control app. With the app, you can set the RGB lights, SPDIF output, audio filters, etc. for a more convenient experience.
- Hi-Fi Audio Performance: This USB C to 3.5mm audio adapter delivers high-fidelity audio performance with a Hi-Res DAC chip that provides excellent and stable decoding performance. It supports a maximum sampling rate of 32bit/384Khz, which is higher than most other USB C headphone adapters available on the market.
- [DAC Chip for Hi-Fi Sound Quality]: Built-in with high-peformance DAC CS43131 and op-amp allows the KA11 to effortlessly produce great Hi-Fi sound.
- [Lightweight but useful and powerful]: The tiny USB DAC KA11‘s body size is only 44x9.7x10.5mm, and it is just about 8.5g. It is convenient and portable for you to take it anywhere. The power can reach 245mW at 16Ω load and 200mW at 32Ω load, which is enough to drive most headphones.
- High-standard circuit components are supplemented by multi-layer immersion gold circuit board design, with strong decoding ability and better detail control. THD+N: <0.0006% SNR: 125dB Noise: <1.7uV
- [Multi-playing ways and portable]: KA11 amplifier with a USB Type-C/Lightning connector, you could use it on Android/iOS phones and tablets or to Windows and Mac computers to get a high resolution sound for listening music, playing game, doing chatting, doing living when you are at home or at office.

FAQ:
Q: What’s the difference between the FiiO E3 and E5?
A: Up until recently the E3 was the only FiiO headphone amplifier available, but that has changed with the arrival of the E5. The E5 features a much more sophisticated design, and has a volume control which means you can use it with a line-out from your DAP.
Q: What’s the price of a FiiO headphone amplifier?
A: The first headphone booster amp from FiiO was called the E3. The E3 costs a mere $7.99 and enables you to run quite demanding headphones from a normal DAP. Up until recently the E3 was the only FiiO headphone amplifier available, but that has changed with the arrival of the E5.
Q: Do you need a AAA battery for the FiiO E3?
A: The only two things you get with the E3 is a mini to mini interconnect and a manual. In order to get the unit to work you need to install a AAA battery. The E5 comes with a far more sophisticated bundle. You get two mini to mini interconnects one with a right angled plug and one straight.
