[FiiO BTR17/BTR7] True Lossless Bluetooth, Portable Bluetooth DAC and Headphone Amplifier BTR17 Is Officially Released!

The battery indicator on the BTR17 is horrible. It shows 40% and then turns off. I haven't seen 20% yet.

Dear friend,

Hi, the battery indicator in the BTR17 or the FiiO Control APP? Are you using the latest firmware?
We will also report to the engineer for improving. Thanks for the kind feedback.

Best regards

It shows the same capacity both in the app and directly on the device. It always shows 40% and then turns off sometimes after 10 minutes, sometimes after half an hour. This happened to me three times in a row. Thank you for passing it on to your technicians

How about the distortion compensation feature setting always resetting to 2 odd and 2 even?

This was reported a long time ago, many times!

same experience here. my btr17 turns off itself shortly after reaching 40%. the battery gauge seems not quite reliable/accurate. already on the latest 0.62 firmware.

@FiiO Support Lin Lin please help to report to engineering team

I also noticed that after 40% it doesn't go down to 20% and shuts off in 15-30 minutes. This is clearly a miscalibration of the battery level.

You're right, no matter what your harmonic compensation settings are, both levels will always appear set to 2 once you exit and re-enter the control app. Good observation

Is there any way to delete all of the eq presets that I don’t want ,so I can just go back-and-forth between eq off and user eq1 ? It is so annoying having to go through all of them every time.

Hi, connecting 2Ω IEMs to the BTR17 could be problematic because the btr17 is designed to handle impedances above 16Ω.
It is not recommended to connect below 16Ω because you could overload the amplifier. Extremely low impedance would cause the output power to go out of control, causing distortion or even damaging the IEMs. Be careful!

My BTR7 seems to drive my SE846 fine so assume BTR17 should do same, even though I think they are 8ohm?

Can get an Open Box one for £139, worth it? Most software issues resolved now?

Hi!. These low-impedance, high-sensitivity IEMs will work well with the BTR17 without any problems, and also with the BTR7. Technically they'll work better with the BTR17 due to less distortion and background noise at high volume. If you say the BTR7 works well for you I don't see why you should buy a BTR17.
And, for example, I don't use the same IEMs for both the BTR7 and the BTR17. Is the BTR17 worth it? In my case, yes

I felt the need for a new toy and want to try Aptx Lossless Vs LDAC and doesn't break the bank, especially at £139.

Also, as powered DAC left plugged in.

I just have SE846, IER-Z1R and Fiio FD7 now via Xperia 1 VI, sold all my DAP's and other IEM's.

I use my BTR17 (4.4mm output) without problems with SE435, aonic 4 and fiio's fh7s other than the EMI issues, and I do prefer it over my BTR15 which these days I only use when the BTR17 runs out of battery

 

[Deathman666]

Not only does the battery show meaningless values during use, but even when charging, after about ten minutes it appears that three bars are charged and then it takes more than an hour for the device to be fully charged..

I also had the BTR15 for when my BTR7 battery ran out. When bought the BTR17 I retired the BTR15. I prefer BTR7 to BTR15.

I'm not saying this is a bad device overall, I bought it and will keep it at least until Qudelix will decide to release a new portable device.
Sound is excellent and the build quality is great.
That said this device has many problems, this thread is full of them, for instance many people are experiencing EMI noise - not me, but it should be mentioned in a review IMO.

But the software is clearly not achieved which negativity impact the device and make the impression it was botched and its launch was rushed.
My main concern is the inconsistency of the EQ depending of the input (BT or USB).
(See this post and the following : https://www.head-fi.org/threads/fii...7-is-officially-released.963808/post-18607553
I'm just surprised that the review omitted the whole EQ function and did not mention this issue which is extremely annoying and basically make the EQ a pain to use if you plan to switch between BT and USB input.
I've bought a Fiio BT11 to completely bypass the USB mode... (That said the BT11 is not the most polished device as well...)

The thing is too many reviews here or elsewhere are biased or sponsored and people often tend to take them as objective whilst they are too subjective or biased.

Perhaps the reviewer did not experience these issues in their use case and testing, and thus did not mention any of these. I also would add that for my use case (Bluetooth LDAC, no EQ) the BTR7 has been flawless. If I were writing a review I would focus on that.

Reviewers should be very clear about their preferences and use cases and consumers should pay very close attention to that. If the reviewers use cases and preferences do not align with the consumer’s, then heavily discount what the reviewer says.

It's arrived, before I even use, didn't realise they had dropped wireless charging which I use on my BTR7. Hmm......


Yep, it's another wow, sounds even nicer than the BTR7 over LDAC and Aptx Lossless

Just listing with my Fiio FD7 for first try out, again sounds better over balanced to 3.5 to my ears, but great over 3.5 too.
