The device is small and lightweight, and it has a clip that allows it to be attached to luggage or garments with ease. The AK4376A DAC chip that’s built into the BTR7 is a high-performance component that promises to offer high-resolution music with low levels of distortion.
In addition, the BTR7 is compatible with the LDAC and aptX HD audio codecs developed by Qualcomm, making it capable of streaming high-quality audio wirelessly. The FiiO BTR7 has caught the attention of audiophiles as well as listeners who only occasionally pay attention to music because of its stylish appearance and impressive feature set. Within the context of this review, we will investigate the numerous capabilities of the FiiO BTR7 and evaluate its performance in comparison to that of its rivals.

Design and Build Quality

The FiiO BTR7 looks like a USB drive because it is small and smooth. It is small enough to fit in a pocket, and it comes with a clip that can be used to connect it to clothing or bags. The device is made of metal, which makes it look and feel high-quality. The device is also long-lasting and can handle regular use because it is made of metal.
On the front of the device is a small OLED monitor that shows the battery level, the Bluetooth codec being used, and other important information. Even in bright sunlight, the screen is easy to read, and it adds to the device’s general good looks. You can buy this Fiio BTR7 from its official website
Fiio BTR7: Display
The BTR7 has a 1.3-inch color IPS display on the front, which is another clear improvement. The main screen typically shows PCM, DSD, or Bluetooth levels, as well as the bit rate, battery level, and volume setting, depending on what is running.
On the other hand, if you press the power button for a while, you’ll get a screen with a lot of options. There are things like a 2-stage gain, a fast and hybrid DAC filter choice, a car mode, and a few other things.
Fiio BTR7: Software

To be honest, the FiiO control app has its pros and cons. For example, the EQ doesn’t work on the UTWS5, but it does on the older UTWS3. The good news is that the BTR7 seems to be working fine.
Not only does the equalizer work, but it also has a hidden function called PEQ, which is a full equalizer with adjustable parameters. This is also called a parametric equalizer, and it lets you change the frequency, gain, and Q of each EQ band.
Fiio BTR7: Battery Life
The FiiO BTR7 has an 880mAh battery, which, according to the manufacturer, can provide 9 hours of use. If you used really sensitive IEMs and kept the level low, you may get close to that.
Obviously, when using modern headphones at a loud volume, that figure drops significantly. Seven and a half hours is enough for a full day of activity or a lengthy flight, and that’s about what we got on average.
Final Words
The BTR7 is a “buy-it-once” device with a battery that can’t be changed by the user but is flexible enough to handle most situations with ease. Almost any pair of IEMs or headphones will work well with it. It can be hooked up to your computer as a wired DAC/Amp. It can link to your phone through Bluetooth. Other devices may do one thing as well as or slightly better than the BTR7.
Fiio BTR7 review: The good and The bad
The Good
- High power 4.4mm balanced output
- Great screen
The Bad
- Larger than a typical dongle DAC/amp
FAQS
Audiophiles will like that they can choose between 3.5mm uneven and 4.4mm balanced outputs, which is great at this price point. We used MQA files played from TIDAL to test the BTR7, and the sound was great. This little player is a great deal for the money and well worth the cost.
The battery life is said to be between 7 and 9 hours, based on the Bluetooth codec, gain, volume, and headphone output used. With a 2A charger, it takes between 1 and 2 hours to charge. The BTR7 and the FiiO Control App work well together.
