I compared the dimensions the other day with the Colibri specs (as I have a Colibri at hand). They’re pretty similar.

In all honesty the Colibri in hand doesn’t feel that different from a usual dongle. Mathematically it might seem a much bigger three dimensional volume than a dongle like the Chronos or Questyle M12/15 - all of which I have at hand to compare in person. But in everyday use it’s not really that different, so I think “slight” is fine for the size description, because that’s how it feels in person. Mojo (which I also have at hand) feels much more substantial and inconvenient for portable use than the Colibri. So if BTR7 is Colibri-sized (which the specs confirm) then I won’t have any problems using it on the go.

An iPhone 13 Pro Max is 42% larger than an iPhone SE. No one--absolutely no one--would say the former is slightly larger than the later, except facetiously or ignorantly or dishonestly. It's a substantial difference in size which also feels substantial. To get from the one to the other, you need to cross several size categories. We're talking twice again that increase. Once more, assuming your dimensions are accurate (and don't include the clip) there's no way to interpret an 84% size increase as "slight," and no universe where trying to pass it off as that could be interpreted as honest. It's nowhere close to the realm of subjective license.

Sorry, maybe my answer is not as strict as yours

In fact the size we are published on the official website. And "Slightly larger" is my intuition, I do not think that the smaller the product, the better, but from his design and functionality.

Just like @EdgeDC said, because of the existence of the display and 4.4mm headset holder, the product size is definitely larger than BTR5

Sure, easy to agree that they have some responsibility, but in the case they were misled by a manufacturer the lion's share is on the later. I hope this is easy to agree with too. Correct information existing somewhere on the internet does not give manufacturers carte blanche.

I think that ~40% larger when the baseline is a BTR5 is — to me at least — close enough to qualify as ”slightly” larger. Now, when the baseline is a typical suburban home, 40% larger would not feel ”slightly” larger.

You definitely have every right to draw your conclusions. Hopefully you won’t begrudge the conclusions drawn by others.

I don't fully agree, but I think you have at least in every way successfully blow up this issue to deter any reasonably intelligent human from mistakenly buying BTR7 because it is "slightly larger" than BTR5. So if you are still unhappy at this point, just don't buy it. I really don't see how this holy war be any more meaningful / meaningless going forward for both sides of the argument. Let's move on.

Sorry Everyone, Sorry @Jeff Graw :

First of all, I did not intend to mislead, and in fact I never calculated how much it has increased compared to BTR5

Thank you for calculating the 84% value, which I really haven't done before either. It's just how I feel in my hands. Maybe I've been doing a lot of larger products lately and haven't paid much attention to that.

In fact I often communicate the content here with the aim of making more consumers more aware of our products.

I sometimes make some mistakes, thank you for the correction.

I hope not to dwell on this anymore.

Thanks again @Jeff Graw for your seriousness, I will follow up by paying attention to the words used and try to answer your questions with data


Special note, the picture above this figure is also displayed in equal scale

I don’t mean to drag this on, but after posting above I thought I should have included some photos for perspective.

Here’s the dimensions of:
Colibri: 77 x 35 x 14
BTR7: 84 x 40 x 14.5

And here’s how Colibri looks against the DACs I have, with the good old iPhone 6S thrown in to have a phone for comparison:

And thickness:

I don’t understand. What does EQ have to do with LDAC? Isn’t the adjustment made before the handoff to Bluetooth regardless of which Bt codec?

On the BTR5, EQ was available on all Bluetooth codecs with the exception of LDAC. Given the increased demands of LDAC the Bluetooth chip was not able to process the EQ in the implementation. The upgraded Bluetooth chip in the BTR7 solves this problem.

No worries. In fairness it did get blown a bit out of proportion (no pun intended), when myself and a few other posters got stuck in a feedback loop.

Could FiiO comment on the decrease in SNR performance from the BTR5 2021 to the BTR7 shown in this comparison from their German website? I was hoping for and improvement in the BTR7 to be across the board but if this is the case I am considering just upgrading to the BTR5 2021 version.

Would that difference in SNR be detectable to humans... or bats...?

Unless the size of the device puts you off, the BTR7 seems to be an upgrade over the BTR5 2021 (screen, battery, output power). If FIIO succeds in getting PEQ to work over LDAC (as they reported they are trying to) it would be a great win (if you care about LDAC & PEQ).

I really like the look, but dunno if it warrants a upgrade over the btr5

I think there is more that goes into the sound quality than just the quoted SNR, but having it go down by 4 dB doesn’t seem like a good sign and I am wondering if there is an explanation why.

Nothing wrong with you asking the question.

Could it be due to THXAAA-28 amp in the signal path?

 

[bwardrop]

Would I be able to use this with a PS5 and a gaming headset with 4 pole? Not a lot of dacs support UAC1 and this looks like a fantastic option if it works.

The BTR7 DAC direct out of the noise and the BTR5 is basically the same, the difference is that the BTR7 added Independent amplified power amplifier circuit（like THX AAA28*2 etc.） , so the SNR is little smaller.

But 118dB is also very good,better than many players and desktop decoders.

 

[FiiO Willson]

Yes, the THX AAA 28 amp of high power at the same time, will increase the amplification of some noise,
But overall SNR reduction is very small, so the BTR7 is still very good
