USB DAC Computer Sound Card

Connect the device to a computer to use it as a USB DAC and headphone amplifier. The sampling rate is up to 384 kHz/32-bit and is fully powered by the computer.

.

Bluetooth Chip

Enjoy your favorite music via a wireless Bluetooth connection with an advanced Bluetooth 5.0 chip that supports SBC/AAC/aptX/aptX HD/LHDC/LDAC Bluetooth encoding..

Powerful 700 mW + 700 mW Outputs

An independent power supply system with low noise and high current output is specifically designed for the CS43198 DAC's built-in amplifier.

.

3.5 mm + 4.4 mm headphone outputs

The Fiio JM21 has been upgraded to the more common 4.4 mm balanced headphone jack, providing more reliable and durable connections. It also features a 3.5 mm single-ended headphone jack, making it compatible with the various headphones you already own. In addition to supporting two headphone outputs, the JM21 offers a maximum output power of up to 700 mW, making it compatible with a wide range of headphones.

.

Compact and Lightweight Design

The power-saving features of the 680 processor enable a thinner and lighter product, significantly improving portability. Combined with two power-saving Cirrus Logic CS43198 DAC chips, the JM21 achieves a stable battery life of over 9 hours (9.5 hours in balanced mode, 12.5 hours in single-ended mode), even with a 2400mAh battery.

The JM21 features a dual-tone frame design with an aluminum alloy center frame and a plastic back cover. This design makes the product appear slimmer. The aluminum alloy center frame provides robust support and protection for the display. The plastic back cover was chosen for its light weight and also serves as the battery compartment.

The back cover has a chamfered surface for a better grip.

Entry-level price, premium configuration

The 680 processor is considered a lower-end configuration compared to FIIO's mid-to-high-end products (and even the broader music player industry). In this case, it's a low-end device equipped with a high-end processor. Two CS43198 DAC chips are standard configurations for mid-range portable audio products. Some users may compare them to portable USB dongles and assume their sound quality is similar. However, the two are fundamentally different. A very important point is that the music players have a built-in battery, whose power source and flexibility are much higher than USB dongles that draw power from smartphones.

This is one reason why the JM21 can deliver an output power of up to 700 mW. Another point is the digital audio signal path. The player utilizes the main control chip and FPGA for jitter reduction prior to DAC conversion, ensuring a direct signal path with a high correlation to the quality of the source. In contrast, portable USB dongles rely on USB transmission from the phone via a cable for decoding and amplification, which introduces additional factors that can degrade the audio signal.

.

Various Connections and Features

The 3.5 mm and 4.4 mm headphone outputs also serve as line-out (LO) outputs, allowing you to connect external amplifiers or powered speakers. In terms of digital outputs, the JM21 supports a coaxial and a USB digital audio output, providing a digital audio source for connection to higher-end decoders. For the coaxial output, you should use a 3.5 mm to RCA adapter, with a maximum sampling rate of 384 kHz or DSD128.

The USB output supports up to 768 kHz or DSD512 in the exclusive USB Audio mode in the FiiO Music app. Internally, the JM21 is equipped with two custom-designed femtosecond oscillators, ensuring sufficient quality for digital transport. These features make the JM21 a versatile device that can serve multiple purposes and meet different user needs.

Worry-free purchase, effortless use

Meeting the needs of users has always been FIIO's primary mission. To achieve this, the JM21 not only comes with excellent product configuration and portability, but also with thoughtful accessories to ensure users have a hassle-free experience. For example, the JM21 comes with a pre-installed PET screen protector and a transparent protective case for comprehensive protection, allowing you to use the product worry-free right out of the box.
