[FiiO BTR15/BTR5 2021/BTR5]Bluetooth DAC and Headphone Amplifier Discussion & Impressions Thread

[dirtdawg]

My video about BTR15



In my opinion, this device offers great value, as it's not only a capable BT receiver, but also a good USB DAC with own power supply

Great vid, thanks! I really appreciate your reviews, very informative.

@FiiO just recieved the Fiio btr15 and i’m beyond impressed. Incredible sound and EQ is INCREDIBLE big step over BTR5 !!!!
Question: do you think you could add Crossfeed fonctionality to the app and device?
That would truly a masterpiece with Crossfeed options !!

Can the BTR15 Bluetooth connect to multiple devices? (Eg. Phone, tablet, computer?)

I have a Samsung Galaxy s23 Ultra, it can go up to 192k in usb wired mode. I do this with my other dac/ dongles, but for some reason the btr15 only displays 48K in USB wired mode, NOT 192k and the toggle switch (UHQ upscaler) to turn it on to 192k on my Samsung is greyed out. This makes the btr5 pretty much useless for me if I want to use it in usb wired mode. The btr15 is set to U Audio 2.0, so that's not the issue. Is there a fix for this?

Edit: I reset the device, shows 192k now. I'll continue to monitor.

Dear friend,

Hi, yes. You could find the instruction from the quick start guide:

My BTR15 used in PC mode (Firmware 2.2) after being closed for a while seem to switch to High Gain despite being set to Low Gain, this while the "L" that indicate that the Low Gain profile is active is showing on the device's display. Switching from Low Gain to High Gain to Low Gain again seems to fix the problem temporarily. Is it a bug?

I have the same problem when using 4.4 output in Bluetooth mode.

@FiiO: Sorry for being that harsh, but you urgently need to work on the Android app and especially on the firmware. How can you just throw such kind of immature (software-)products onto the market?
Latest discovery: Personalized EQ set on USER1 is created -> now every other custom preset is no longer saved permanently. As soon as I create another preset and then switch back to the first one, the newly created one is gone except for the pre-gain.

Please add:

1. Please make PEQ available with UAC 2.0
2. Please add at least low-/high-shelves to the filter types in PEQ

Ever since I upgraded my BTR15 to 2.2 firmware, I can't seem to be able to charge my battery to 100% even after leaving it overnight. It will continue to blink in the last bar. When connected to the app, it's showing 100% correctly.

Dear friend,
Hi,
1. EQ problem: We will improve about that in next APP update.
2. PEQ is available in UAC 2.0mode.
3. We have reported to the engineer for assessing.

Best regards

I have the same problem when using 4.4 output in Bluetooth mode.

Dear friend,

Are there any certain operation to reproduce the issue? And you could hear the volume is louder? Thanks in advanced!

Best regards

This is very beautiful looking!

1. I failed to reproduce the problem with PEQ. Are you using the FIIO Control in latest version 3.18?
2. PEQ is available in UAC 2.0mode.

Thanks for the response!

1. Yep, newest Android and the latest Firmware installed.
To describe a little bit more precise: USER1 Profile is configured (some freq modifications and -xdB in Pre-Amp) and works perfectly. I can switch between EQ Profiles, disable EQ, just as expected. Now, when I change to the USER2 Profile and start modifying it with -xdB Pre-Amp plus some Adjustments everything looks fine. But when I change the Profile from USER2 to USER1 and then back to USER2 everything is gone except for the Pre-Gain. (USER1 is not touched and not reset)

2. Yeah, but NOT for PC or Phone
