I tried to search this forum so apologies if this has been answered. The output for the BTR3 is so low that I have to turn it up all the way to hear anything. I don’t have this issue with the ES100. Is this an issue? Can it be fixed?
Hi there,

It certainly sounds like this is an issue. Which headphones are you using? The es100 does have a bit more power but The btr3 should be able to drive most iems to a really high level. What is the source device? Have you been able to test with any other device?

It might be a silly question, but do you have the volume set to 100% on the source device?

i'm using Periodic Audio Be with a one plus 6. ES100 is okay with medium volume on the One Plus 6, but i have to crank it up to the max on the OP6 on the BTR3.

Hmm it should drive those with no issue based on their impedance / sensitivity. Are you able to connect the btr to a PC/Mac via usb and use it in usb mode? It would be a good test to see if it is a Bluetooth related issue or not.

You could also try to reset the device. Try google search btr3 hard reset.

Anybody know if they make a lightning to type c cable so I can use this as a dac from my iPhone XR? Will I gain anything by doing this? Any noticeable difference from Bluetooth?
I have tried this using the Apple camera adapter cable. I get an error saying device draws too much power. To be honest though it kind of defeats the object of this device. I think usb mode limits the bitrate to 16 also, so ends up being a complicated setup for not much improvement in sound. Just my opinion though.

I tried that, and the sound wasn't better than with the best Bluetooth codecs and the BTR3 got warm/hot. I posted about that in this thread. Check the post for details.

Dear friend,

I think that you could try to turn off the charge option of the BTR3 from FiiO Music app-BT device control and check again.

Best regards

Dear friend,

Please try to reset the BTR3 by holding the power button for at least 10s or holding the volume +&- for 5s to see if it helps first?

Best regards

What USB c to USB c cable should I use to connect the BTR3 to Android as a DAC ? I have multiple USB c cables and the only one that works is the one bundled with Note10 , other high quality cables (nekteck for ex.) The BTR3 is not recognized.

try instead usb A to C, C to C is way too many usb protocol that it's confusing, maybe to btr3

now my question: lowpass filter only works in AptX or does it work with LDAC too? and what does each filter brings? im trying hard to dissect them but cant figure them out

I tried to search the forum so I apologize if it's been discussed.
I connected the BTR3 to my phone and Macbook Pro, but it only plays media from my macbook when it's connected to both. I set "Select Input Device" to manual, it still won't switch when I double click the power button. Automatic mode behaves the same way, even if no media is playing on the mac and media is playing on my phone. Any advice would be appreciated.

Edit: I just tried resetting the device by holding down the power button for 10 seconds, I tried both when the unit was on and when the unit was off and both times it just changed the power state, but didn't reset the device. I'm starting to think that I have a defective device.
