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

whats the purpose of the included USB C to USB cable? I tried it on 2 Android phones, it does not support USB OTG for USB DAC. I thought it was my phones, but i tried another USB C to USB C cable, it works.

Is my included USB C Cable defective?

EDIT: i noticed the cable has arrow on it, it only works if the arrow is pointing towards the BTR5. Why did Fiio design the cable this way?

So, the battery of my 2 year old BTR5 has swollen, and since the warranty has expired I took it apart to see what kind of battery I need as a replacement, but couldn't find the exact model.
I've found a similarly sized battery with a higher capacity though and will be trying it out, 1150mah to be precise, but who knows if said capacity truly holds up.
I'm no expert when it comes batteries or electronics in general but from the looks of it the original battery is a Lithium Polymer type if I'm not mistaken.
Do you guys think any other LiPo battery with 3.7V will work?

My iPhone works with a third party lightning to female USB A OTG, combined wirh the FIIO USB C to USB A. But sometimes you have to unplug and plug to be recognized.

Now I can wait for the FIIO LT-LT3 in relax.

Tried it with my DT880 600ohm… no problems at all! Enough Volume at 30ish.

Only problem I have - how can I play DSDs out from an Iphone over the BTR5?

BTW, I just ordered a Kindle Fire HD 8 2020 (refurbished from Amazon, 60€), want to use it as a dedicated Musik Player in combo withe the BTR5.

Edit: Managed to play DSD using the VOX App.
Using Etymotics ER4pt, for the life of me, I can't hear any or only small difference to 16/44.1 redbook.

Am I the only one?

Dear zeko39,

Sorry about that. Yes, the 3.7V battery could theoretically work with the BTR5 as well.

Best regards

Dear globobock,

You could try the FiiO Music app for playing DSD files.

Best regards

1. Is it normal, that turning EQ with default Custom (all values 0) changes sound output? I mean - shouldn't the output be the same with or without EQ if EQ is set as baseline?
2. Max sound level on Android device seems to be way lower than on PC (both BT connected).
3. Only 2 lowpass filters are available on Android Fiio Control app (linear and hybrid) - reviews online showed more than that - is it limited by app or connected headphones?

Dear prakalejas,
1. When EQ is on, the volume decreases: https://www.fiio.com/newsinfo/63367.html
2. The Bluetooth output level of your Android device may be different from your PC.
3. If you are using BTR5 2021 instead of BTR5, the filters are two.

Best regards

Dear globobock,

You would need to transfer the DSD file to FiiO Music app first in your iPhone.
Help: https://support.apple.com/en-us/HT201301

Best regards
That is unfortunate since I hardly use a PC these days and would rather just work on the phone.

BTW, I manage to do it using VOX, you can simply share the downloaded file to the VOX app using the phone.

It shouldn't be too difficult to enable the FiiO App access local files within the phone, without requiring a PC in between, no?

Dear globobock,

Sorry I am not using a iPhone so I am not quite familiar about that. But in my iPad, the APP could not access the local files unless I upload the files for the certain APP.

You could also try whether the Wifi transfer function in the FiiO Music app could help?

Best regards

The thing is, I don‘t want to use a PC just so that a phone app might use a file that is already on my phone! VOX has hadled it fine, Fiio should be able too.

It also works with Onkyo HF and Hiby Music App - no PC needed for files downloaded directly to the Phone.

BTW, on Hiby, dff files were displayed as DSD on the BTR5 while dsf files were downsampled to 88khz pcm. It is an app problem, I suppose?
