Overview of the FiiO BTR13
The FiiO BTR13 stands out because of its multifunctionality. It’s designed to cater to a variety of audio needs, making it a versatile tool for enhancing audio quality across multiple devices. The BTR13 primarily serves three roles:
USB DAC for PCs and Macs:
Acting as an external sound card, the BTR13 connects via USB, significantly improving the audio output of computers and streaming devices. This function is essential for users looking to bypass the often inferior internal sound cards in their laptops or desktop computers, elevating their listening experience to a higher level.
Dongle DAC for Smartphones:
Modern smartphones, especially those lacking 3.5mm headphone jacks, require a reliable dongle DAC to deliver premium sound quality. The BTR13 fits this need perfectly. Using either a USB-C or Lightning connection, it delivers an enhanced audio experience directly from your phone.
Bluetooth DAC:
The BTR13 doesn’t stop at wired connections. It’s also capable of receiving high-resolution audio streams from a variety of Bluetooth-enabled devices. The BTR13 turns your Bluetooth connection into a high-quality sound system by offering support for multiple codecs that maintain the integrity of your music or podcasts.
The magic behind the BTR13’s performance lies in its components. FiiO has equipped this device with Qualcomm’s QCC5125 Bluetooth chip, a chipset known for its efficiency in processing high-quality audio signals and ensuring stable connectivity. Furthermore, dual Cirrus Logic CS43131 DACs handle the digital-to-analog conversion, which is critical for delivering the high-fidelity sound that FiiO products are known for. These DACs work in tandem to process audio signals separately for each channel, reducing distortion and crosstalk, resulting in crystal-clear sound.
Design and Display
The BTR13 is not only powerful but also designed for convenience and portability. Weighing just 28.6g, it’s lighter than many similar devices on the market. The compact design allows it to be easily carried in a pocket or clipped onto clothing or a bag using the included back clip.
The device features a 0.96-inch color IPS display, which provides detailed information at a glance. The display shows critical data such as battery life, volume levels, and connectivity status, ensuring that users always know the status of their device. The display supports both English and Chinese, making it accessible to a global audience.
Despite its small size, the BTR13 is built to be durable and user-friendly. The overall build quality is solid, and the compact form factor makes it an excellent option for users who prioritize portability without sacrificing sound quality.
Key Features and Performance
The FiiO BTR13 is not just a compact DAC and amplifier; it’s a feature-rich device designed to enhance your audio experience across a wide range of devices and setups. Its connectivity options and high-resolution output make it a standout product in its price range.
Versatile Connectivity and Usage
The BTR13 excels in versatility. It’s designed to be compatible with a variety of devices, making it a one-stop solution for anyone looking to improve their audio experience. The device supports three main modes of operation:
PC Mode:
In this mode, the BTR13 functions as an external sound card when connected to a computer via USB. It processes the digital audio signal from your computer and outputs a clean, amplified sound that outperforms most built-in sound cards. This is ideal for audiophiles who want to improve their music listening experience or gamers seeking enhanced sound immersion.
Bluetooth Mode:
Wireless operation is where the BTR13 truly shines. It operates independently of any external power source, running on its internal battery, and streams high-resolution audio from Bluetooth-enabled devices like smartphones, tablets, or even some smart TVs. It’s a portable solution that frees you from being tethered to a specific device while still delivering excellent sound quality.
Phone Mode:
When connected to a smartphone via a USB cable, the BTR13 acts as a dongle DAC, bypassing the phone’s internal audio processor. This significantly improves the audio output, especially on devices that lack high-quality sound chips. The internal battery ensures that the device doesn’t drain your phone’s power while delivering superior sound performance on the go.
High-Resolution Audio and Output
The BTR13 supports audio playback up to 24-bit/96kHz PCM, which is a critical specification for maintaining high-resolution sound. It also utilizes Qualcomm’s QCC5125 chip for Bluetooth transmission, a chipset that is capable of supporting high-resolution audio codecs like AAC, SBC, aptX, aptX LL, aptX Adaptive, and LDAC. These codecs ensure that the BTR13 can maintain high-quality audio transmission even over Bluetooth, preserving the richness and detail in your music or media.
The dual Cirrus Logic CS43131 DACs further contribute to this device’s high-quality output. By processing each channel separately, these DACs reduce crosstalk and enhance clarity, providing a more immersive and accurate listening experience. This setup makes the BTR13 particularly well-suited for audiophiles who appreciate subtle details in their music.
The BTR13 offers two headphone output options:
3.5mm Single-Ended Output:
Capable of delivering 100mW of power into 32 Ohms, this standard headphone jack is ideal for most consumer headphones and IEMs (in-ear monitors).
4.4mm Balanced Output:
For users with higher-end headphones or those requiring more power, the balanced output delivers a whopping 220mW into 32 Ohms, a 282% increase in power compared to FiiO’s previous model, the BTR3K. Balanced connections provide better channel separation and lower noise, resulting in a cleaner and more powerful audio experience.
Parametric Equalization (PEQ)
One of the standout features of the BTR13 is its 10-band parametric equalizer (PEQ). Most devices in this price range offer limited or no equalization options, but the BTR13 goes above and beyond by providing a fully adjustable PEQ. This feature allows users to customize the audio output to their liking, whether they want to tweak the bass, mids, or treble, or correct specific frequency response issues with their headphones.
The parametric EQ can be controlled via the FiiO Control app, available on both iOS and Android or through FiiO’s web portal. This level of control makes the BTR13 a flexible tool for tailoring your audio experience to your personal preferences. Whether you’re a bass-head who wants more thump or a purist who prefers a neutral sound, the BTR13 can be adjusted to suit your needs.
The EQ functionality is available in both Bluetooth and USB DAC modes, making it a versatile feature that enhances the BTR13’s appeal as a comprehensive audio solution.
