FAQs
What is the warranty on the FiiO BTR3K?
All FiiO products come with a year warranty. You can simply get in touch with us to claim the warranty.
Can I use the original USB-C cable of my Macbook to charge and for DAC?
We can use dual TYPE C cable connecting to Macbook and Macbook Pro for charging as well as USB DAC output. Because the original wire material is too long which would slow the recognition down. When the cable is not recognized, you can unplug it and insert again.
When connecting to the computer in USB DAC mode, you can find that the audio output device appears FiiO BTR3K. With the white light on, the sound can be output. It is recommended to use FiiO LT-TC1, a double-end TYPE-C cable, which can be perfectly matched with the charging box data function of your Macbook Pro. What's more, it can also be charged by connecting the PD charger.
Does the BTR3K support in-line remote and the microphone function?
【In-line remote】
The BTR3K supports the CTIA standard for line control as well as line microphone. But the headsets with OMTP protocol only support normal listening.
【Microphone recording】
Android-based cellphones can normally use WeChat,Wechat calls, QQ voice and QQ calls. The phone microphone is used when taking videos, using QQ voices and Wechat voice. It depends on different systems of mobile phones. iOS system only supports WeChat voice, calls and QQ calls with the microphone of BTR3K. If taking a video, the phone microphone is used.
What adapter is suggested to use?
The BTR3K does not support fast charging. It is suggested to use common 5V/2A adapters.
About the standby function and the battery life.
【Stand-by function】
No playback and operation means the BTR3K is in stand-by mode after connecting. When there is no connection, it would automatically turn off after about 2min(you can choose the working time in the APP's settings). Its battery life is about 300 hours in idle status.
【Battery life】
With a built-in li-polymer battery, its battery capacity is 330mAh. Under low gains mode in AAC codec, it can continue to work for 11hours with merely 1.5-hour charging time. LDAC priority would allow a battery life for about 8 hours ; LDAC standard for about 9 hours; LDAC connection priority for about 11 hours; aptX for about 9 hours.
Why does the volume of the mobile phone not change when the BTR3K adjusts the volume?
1.There is a memory function within the BTR3K so that it can automatically adjust the volume.
2. We have deliberately designed the volume adjustment of the BTR3K out of sync with the mobile phone which makes it possible to adjust the volume in a more precise level and avoid many problems.
What the mobile phone can adjust is the the volume of the Bluetooth codec. If its volume is too small, the dynamic effect would be affected. While the BTR3K controls the volume of decoding and amplification which can decrease the loss of the sound quality. Therefore, it is recommended to adjust the volume of the phone to the maximum, and control the volume by the BTR3K.
How to use the aptX HD/LDAC?
The high-quality Bluetooth encoding format needs the support of the transmitter first(such as mobile phone), and then you need to correctly select the corresponding encoding format (some mobile phones can set the Bluetooth encoding format in the developer options, but different mobile phone's settings are different, please consult the mobile phone Vendor's customer service for more information)
iPhone devices are limited within AAC and SBC formats so that the Bluetooth codecs could not be switched. Normally it is defaulted as AAC, and SBC in phone calls.
Can the BTR3K work as a DAC for the computer, and how?
The BTR3K can be connected to a computer and work as a DAC, which supports the sampling rate up to 48K/16b. Use any USB TYPE-C cable to connect the BTR3K to a computer. Once the BTR3K is on, it would automatically work as the USB DAC mode.
It is prior as USB DAC . Therefore, when the BTR3K is working in both Bluetooth audio and USB DAC outputs at the same time, it would take the USB DAC output as the priority. By connecting it to the app the output modes can be selected in the settings menu.

What is the warranty on the FiiO BTR3K?
All FiiO products come with a year warranty. You can simply get in touch with us to claim the warranty.
Can I use the original USB-C cable of my Macbook to charge and for DAC?
We can use dual TYPE C cable connecting to Macbook and Macbook Pro for charging as well as USB DAC output. Because the original wire material is too long which would slow the recognition down. When the cable is not recognized, you can unplug it and insert again.
When connecting to the computer in USB DAC mode, you can find that the audio output device appears FiiO BTR3K. With the white light on, the sound can be output. It is recommended to use FiiO LT-TC1, a double-end TYPE-C cable, which can be perfectly matched with the charging box data function of your Macbook Pro. What's more, it can also be charged by connecting the PD charger.
Does the BTR3K support in-line remote and the microphone function?
【In-line remote】
The BTR3K supports the CTIA standard for line control as well as line microphone. But the headsets with OMTP protocol only support normal listening.
【Microphone recording】
Android-based cellphones can normally use WeChat,Wechat calls, QQ voice and QQ calls. The phone microphone is used when taking videos, using QQ voices and Wechat voice. It depends on different systems of mobile phones. iOS system only supports WeChat voice, calls and QQ calls with the microphone of BTR3K. If taking a video, the phone microphone is used.
What adapter is suggested to use?
The BTR3K does not support fast charging. It is suggested to use common 5V/2A adapters.
About the standby function and the battery life.
【Stand-by function】
No playback and operation means the BTR3K is in stand-by mode after connecting. When there is no connection, it would automatically turn off after about 2min(you can choose the working time in the APP's settings). Its battery life is about 300 hours in idle status.
【Battery life】
With a built-in li-polymer battery, its battery capacity is 330mAh. Under low gains mode in AAC codec, it can continue to work for 11hours with merely 1.5-hour charging time. LDAC priority would allow a battery life for about 8 hours ; LDAC standard for about 9 hours; LDAC connection priority for about 11 hours; aptX for about 9 hours.
Why does the volume of the mobile phone not change when the BTR3K adjusts the volume?
1.There is a memory function within the BTR3K so that it can automatically adjust the volume.
2. We have deliberately designed the volume adjustment of the BTR3K out of sync with the mobile phone which makes it possible to adjust the volume in a more precise level and avoid many problems.
What the mobile phone can adjust is the the volume of the Bluetooth codec. If its volume is too small, the dynamic effect would be affected. While the BTR3K controls the volume of decoding and amplification which can decrease the loss of the sound quality. Therefore, it is recommended to adjust the volume of the phone to the maximum, and control the volume by the BTR3K.
How to use the aptX HD/LDAC?
The high-quality Bluetooth encoding format needs the support of the transmitter first(such as mobile phone), and then you need to correctly select the corresponding encoding format (some mobile phones can set the Bluetooth encoding format in the developer options, but different mobile phone's settings are different, please consult the mobile phone Vendor's customer service for more information)
iPhone devices are limited within AAC and SBC formats so that the Bluetooth codecs could not be switched. Normally it is defaulted as AAC, and SBC in phone calls.
Can the BTR3K work as a DAC for the computer, and how?
The BTR3K can be connected to a computer and work as a DAC, which supports the sampling rate up to 48K/16b. Use any USB TYPE-C cable to connect the BTR3K to a computer. Once the BTR3K is on, it would automatically work as the USB DAC mode.
It is prior as USB DAC . Therefore, when the BTR3K is working in both Bluetooth audio and USB DAC outputs at the same time, it would take the USB DAC output as the priority. By connecting it to the app the output modes can be selected in the settings menu.

"Volume adjustment is independent from the source device,whether the BTR3K is connected via Bluetooth/USB.In both cases it keeps its own volume that's distinct from the source."

"The sound of BTR3K is very clear warm & smooth,with a thicker presentation,less treble energy than BTR5, it very clearly favors neutral and brite IEM's,rather than warm & neutral ones."

"The main shell is made of aluminium alloy while the front and back are 2.D reinforced glass,the device will inspire confidence to use it without fear of falling apart. "

"Bass is natural with normal depth & resolution, but both parameters are slightly cut off by Bluetooth codecs.There are no attempts to force bass and it is good for textures & technicality."

"The trick with FiiO BTR3K is that it is affordable, mini-sized, and most probable to be paired with a Chifi IEM, all of which are known for their fairly strong treble and bright signatures."
