Is it possible to adjust the volume of the "Power on", "Power off" voice, or turn the sound off?
It sounds too loud to me....

fiio replied to someone else asking in this thread a couple of sites before. you would probably find what its named like with a quick search. me too lazy today tho

The voice volume slider is called "volume of tones". I guess it's called that way because I presume it controls call ringing, but I don't use my BTR15 for calls, so I can't tell. Anyway, you can lower/mute the voice with this slider.

I apologize if I’m repeating myself, but is there anything you can do about the delay in playback that affects the BTR15? When starting, pausing, and then starting again, there is a significant delay in the audio. A similar problem existed with the KA17, although to a much lesser extent. However, with the latest firmware update, it seems to be fixed. Could you implement the same fix for the BTR15? The problem is present in both PC and BT mode.

Hi, I too hope they release a firmware update to fix the annoying low gain bug. And all this long before your current complaint about sound delay that you tell us about now. It seems they can't fix the latest bugs and probably won't be able to fix it due to device limitations. Will they bring out a new Btr15 2024 like they did with the btr5 and brought out the btr5 2021?

Dear friend,

Hi, the engineer told me that the firmware for fixing the low gain bug could be available in this week. We will share to you when we received the update from the engineer.

Best regards

Dear friend,

Hi, the firmware is now available.
Firmware download link: https://fiio-firmware.fiio.net/BTR15/BTR15_V3.8_trial_p.bin
Local upgrade:
1. Import the "BTR15_Vxxx.bin" firmware into the mobile phone;
2. Set the button on the side of BTR15 to the BT position and connect to Bluetooth in the phone settings. Download the Fiio Control App on your phone and connect the BTR15. On the BTR15 page, click the settings pattern in the upper right corner, find "Firmware Upgrade", find "Local Upgrade", select the firmware imported to the phone, and start upgrading the firmware.
Please note: During the firmware upgrade process, please do not leave the upgrade interface, otherwise the upgrade may fail! The upgrade may take a long time, please be patient. If the upgrade fails, you can try again.

Changes:
1. Fixed the issue where the low gain setting will change to high gain after reboot;
2. Fixed the issue where the UAC1.0 setting will change to UAC 2.0 after rebbot.

Best regards

That's the gain bug fixed, alright. Thank you, Fiio! I only tested over BT, gain remains at low even across multiple reboots, and display show correct gain setting. Can't comment on behavior over USB, though.

Looks like this isn't the definitive version, since the file aboves shows "trial" in the name and the BTR-15 firmware page doesn't show this update yet. Wonder if we're the guinea pigs for this firmware

Personally I'm happy to be a guinea pig if they fix the problems and there is no risk of bricking the device

same, if the device gets bricked tho they probably will say you did it at your own risk

Hi, I'm doubly happy! You have delivered in one week 2 firmware updates for the best mid-range and high-end portable bluetooth amplifiers available: BTR15 and BTR7. Thank you so much!

i am trying to update the way it was described. Loaded the bin on my phone, connected the BTR15 via BT with my phone, went to the app and clicked local upgrade. now its already 10 minutes saying "Updating device 0,0%". is that normal?

edit: second try seems to work
