FiiO BTR17 Overview

Experience outstanding audio quality on the go with the FiiO BTR17, a portable Bluetooth DAC and headphone amplifier that features dual integrated DACs that deliver a refined, detailed, and articulate listening experience, even when listening to music over Bluetooth. At the heart of the BTR17 is the dual ES9069Q DAC chips, which handle sample rates and resolutions up to 768 kHz / 32-bit. This DAC is housed alongside the Qualcomm QCC5181 Bluetooth chip to provide support for Bluetooth 5.4, as well as Bluetooth aptX and SBC.

The patented Desktop mode features an independent power supply, which boosts performance considerably. The enclosure provides ample protection, as well as a space-age 3D aesthetic that not only looks great, but is easy to handle. The built-in rechargeable battery lasts for up to ten hours, ensuring you can listen to music wirelessly for a long time. The BRE17 includes a leatherette case and a specially-made short dual USB-C OTG data cable.

Patented Desktop Mode
The BTR17 features a dedicated Desktop mode switch along with a dedicated USB-C port to connect an external independent power supply. In Desktop mode, you can connect the BTR17 to a phone as a dongle DAC and headphone amplifier. This method of connection provides considerable performance boosts and will keep the internal battery charged.
High-Precision Lossless Parametric EQ
The BTR17 features a high-precision lossless parametric equalizer (PEQ). The continuously refined proprietary PEQ adjustment algorithms allow you to finely adjust EQ and frequency points, gain bandwidth, and Q value to your liking.
Dual Cores and Four Channel ESS DACs
Inside the BTR17 are tow ESS ES9069Q DACs based on fourth-generation 32-bit HyperStream architecture, achieving high performance while using less power. The architecture helps to further reduce digital noise within the DAC, allowing it to hit 103dB dynamic range and -120 dB total harmonic distortion, resulting in a richer, musical sound against a clean audio background.
THX AAA 78+ Headphone Amplifier
The BTR17 uses the THX AAA 78+ headphone amplifier, the same amp used in the renowned FiiO KA17 and M23. The four-channel fully balanced design utilizes eight op-amps in parallel to ensure robust yet controlled power, for a clearer and more natural sound.
Multi-Stage HiFi Audio Architecture
The BTR17 integrated mid-to-high-end HiFi player-level signal processing within its compact body. Digital signals are deftly handled by the dual-clock digital audio and DAC. LPF preamplification and multi-stage analog audio processing ensure details and the dynamic range within audio signals are precisely restored, comparable to premium digital audio players.
Comprehensive Protection Circuits
Built-in temperature and DC output detection prevents damage to the device and headphones if abnormal conditions are detected for safer usage. Volume limit prevents accidental loud volumes and protects against hearing damage.
All New User Interface
The new UI made possible by the 1.3" IPS color screen supports both Chinese and English displays. The font color even changes along with the audio format. The overall design ensures the user can intuitively use it and easily grasp its current status.

Incredicle Headphone Amplifier

This amplifier provides an incredible audio experience for anyone who wants to link either via Bluetooth or USB A. The audio qualify can be mixed to your individual taste. I use it for Logic Pro and Cue Base with spectacular results. It is also small and portable. I recommend it highly this amp.

The difference it makes isn't just subtle.

I'm not an audio expert, but I've been moved to upgrade my audio systems lately. After reading an enthusiastic review of this unit online & following it up with further research, I bought one for my desktop computer setup, where I listen with headphones. After installing the BTR17 and making sure to plug it into a good source of power (in this case, an AVR battery backup, the difference in the sound quality of the music I listened to was noticeably, markedly improved over just plugging headphones into a line out in the desktop computer. Which led me to buy another BTR17 for my car -- which soon led me to buy one for a friend who is always driving ridiculous distances. Putting my money where my opinion was.

How is this compared w BTR15. I wonder which should I buy ?
Asked by: James
The FiiO BTR17 Portable Bluetooth DAC and Headphone Amplifier and the FiiO BTR15 Portable Bluetooth DAC and Headphone Amplifier both use the same DAC chip. The BTR17 is a larger size and it has a larger IPS color display, as well as a more powerful headphone amp, a higher USB DAC sampling rate with a lower noise level, and a higher capacity battery. It also features desktop mode support and CTIA mic and in-line control, which the BTR15 does not provide, Users report the bass sound of the BTR17 to be punchier than that of the BTR15.
