My chargers are Gan II smart chargers, they supposedly provide even cleaner power than regular chargers. But like I said, I suspect that my problem is linked to the charging system. I replicated once more the problem and I noticed that the FiiO was actually not charging even when the display said it was. Then I believe that when the battery was about to get depleted the screen started to act very crazy and the offending noises shouted again (this time plugged to some cheap headphones). Since the unit died because it was actuallynot charging, I re plugged the power cable and it took the FiiO a couple minutes of flaking acting weird screen displaying charging state to normalize and continue charging normally.

I’m now 24hr on a "dumb" lower quality charger and the problem has not replicated. Will update if something else happens.

I regularly charged my BTR7 with a Gan Anker 65 watt charger (its my go to travel charger), havent expirianced what you described,

Use my BTR 7 with my work laptop, my Huawei M6 tablet and Xiaomi Poco F5 cellphone, both cabled and LDAC to mostly play Youtube music, Spotify and Flac using AIMP.
and headphones B2, Soundrhyme SR5 and currently ZiiGaat Dos Cinco.

Hello FiiO,

I would really appreciate the possibility of changing EQ settings while BTR7 is in USB-DAC mode and playing music.

Is this something that can be implemented via firmware update?

With Q5K it is possible to be connected via USB and also via bluetooth which makes a lot of sense for all the settings

Dear friend,

Hi, you could set the BTR7 in UAC 1.0 mode for help? The EQ adjustment could be available in UAC 1.0 mode.

Best regards

THX Portable Bluetooth DAC/Amp BTR7 Design Story

Chapter 1 Product Positioning of Bluetooth DAC and Headphone Amplifiers-By FiiO Willson
Chapter 2 THX AAA Amp Technology-By FiiO Matt
Chapter 3 Bezel-less IPS Display
Chapter 4 Wireless Charging

Hot-spot Q&A about FiiO BTR7
1. Is there any plan for a back clip?


The BTR7 comes with a leatherette case. While the back clip is clipped on clothes or bags. Since the BTR7 is slightly larger and heavier than the BTR5, the experience of using a back clip is not very good. So it is suggested to use a leatherette case and put it in the bag or pocket. Moreover, we will keep collecting user feedback. If there is a certain demand, we will consider designing a separate back clip.



2. What are the differences between the Apple and Android versions? When will the Apple version be available?

The only difference is that the Apple version includes an extra adapter cable. And it is expected to be available in August.



3. How is the battery life of the BTR7 under LDAC Bluetooth?

There are some differences between different Bluetooth codecs. Please refer to the following test data for details.

1) AAC + Low gain + 3.5mm output: About 9 hours

2) LDAC + Low gain + 3.5mm output: About 8.5 hours

3) AAC + Low gain + 4.4mm output: About 8 hours

4) LDAC + Low gain + 4.4mm output: About 7.5 hours



4. Which one is better, the BTR7 or Q3?

They have different positioning. Even if some functions and performance are similar, it is suggested to consider the main usage scenarios.

The BTR7 is mainly flexible and portable with Bluetooth as the main feature. However, it is weaker than the Q3 when used as a USB DAC bundled with mobile phones. Because the Q3 has a larger battery capacity, and has a form and factor that is more suitable for bundling with mobile phones. Also, we have designed a set of strapping kits for the Q3.



5. When connecting the BTR7 via USB and playing 24bit tracks through FiiO Music app, why would the BTR7 show 32bit?

The bit depth displayed on the BTR7 is the bit depth of the song transmission, which is different from that of the track. This is the best compatibility we chose when customizing the XMOS USB AUDIO driver. 32bit is compatible with both 32bit and 24bit. When playing a 24bit track, the 32bit displayed actually means the transmission mode of the USB driver, but does not mean that it is a 32bit file, and XMOS does not upsample the 24bit track.



6. When connecting the BTR7 to a mobile phone via Bluetooth, and switching the bit depth in the developer options of the mobile phone to other bit depth options, why would the BTR7still show 24bit?

You will find that it will also display 24bit under SBC encoding. In fact, this 24bit refers to the audio processing bit depth after decoding through Bluetooth. It is not the same indicator as the bit depth in the developer option of the mobile phone, nor is it the same one as the track itself.

This is related to the internal DSP of the Bluetooth chip QCC5124. To exert the maximum performance and audio processing capability of the DSP, we have adopted the highest 24bit specification. All decoded Bluetooth audio will be processed in 24bit before sending to the ES9219 DAC.



7. In the parameter table on the official website, the SNR of the BTR7 is not as good as that of the BTR5. Why?

In the BTR5, it drives the headphones directly from the ES9219 DAC, so its amplification multiple is fixed.



While in the BTR7, there is a THX amplifier added behind the DAC. It supports both front and rear amplifying which has higher amplification multiples than that of the BTR5, so the noise floor is higher. These can help to improve the output power. But in terms of the noise floor, it will not affect the listening experience.

If you are sensitive to the noise floor, you can try to set the gain level to "Low".



8. Is it normal that the charging switch is slightly loose?

The size of the switch has a design tolerance. If it is too tight, it will affect the feel. It is normal that the switch is slightly loose and it will not affect the function.



9. Is it normal that some parts of the display are still on at certain angles when the screen is turned off?

It is normal this happens within one minute when turning off the screen. It will gradually disappear. Don't worry.



10. Is dual DAC working when using the 3.5mm single-ended output?

Yes.



11. Can the microphone work in USB DAC mode?

No. But it can work when connecting the BTR7 to a computer through Bluetooth.



12. Will EQ take effect in USB DAC mode?

In UAC2.0 mode, EQ cannot be adjusted. While in Bluetooth and UAC1.0 mode, EQ can be adjusted.



13. Can the display screen display the song title, lyrics and other information?

In theory, it can work. We will evaluate whether to add it after the software is stable.



14. If the BTR7 is used as a dongle DAC with the charging switch off, how long is its battery life?

It has about 4.5 hours for the 3.5mm output, and about 4 hours for the 4.4mm balanced output.



15. Can the BTR7 be used as a dongle DAC when it is out of power?

No. It needs to be charged.

If the charging switch is turned off, the BTR7 will not be charged even when connecting to a USB cable. At this time, it will consume the power of the built-in battery.



16. How to adjust the volume of the BTR7?

It is suggested to set the volume of the mobile phone to the maximum, and control the volume through the BTR7. This will achieve for the best transmission with less distortion.

Please add the feature of seeing the music title on the display, in that way the display would be much more useful. And for me personally would not have to grab my phone over and over again and cause distraction.

Just seeing in what codec is being on the display in a big bold font is mostly useless, it would be better if you guys can shrink it up and put it in a corner. And make the music title on the center. For example like the ikko itb03

In my opinion this is will be a more proper use of that display.
Thank you, hoping that you guys will implement it.

Dear friend,

After assessing, we found that adding the music title or lyrics support on the display would require the support of different languages. The capacity of our chip is not enough to support that so we do not have the plan of adding this feature for BTR7 now.

Best regards

How about just add the support of english as of now. And if any other language is needed , the old interface comes back. (The one with big codex icon and all)

Dear friend,

We may not consider about that currently or the users using other languages may require for adding their languages.

Hey Amgio,

this does not help, as soon as i connect BTR7 via usb it will loose bluetooth connection to fiio control app

How does KA17 and Q15 behave in that regard? Not being able to use PEQ while playing music via USB is kind of a bummer for me

Dear friend,

1. You could set the EQ via Bluetooth connection first. The EQ setting could be saved when using UAC1.0 mode.
2. The KA17 and Q15 could support PEQ in USB mode.
