Thanks! So we know the 625 supports high definition audio. I guess the question then is how/if it has been implemented.

I say not bit perfect. I say this because when i connect my Mojo, i can still adjust the volume on the phone - when in fact (if implemented correctly) i shouldn't be able to.

Yes, it seems if people's anecdotal evidence is correct, they may not have implemented the full capabilities of the SoC. Still, it would be nice to know what the 'officially supported' audio specs are to eliminate the guessing game and help us get the most from our devices. The fact it doesn't seem to be mentioned at all isn't very encouraging mind you...
Thanks...so these numbers would appear to indicate it compares quite well with other high end devices out there, at least when it comes to the audio quality. Is that correct?
I doubt that its on their priority. I'm more thankful that they spent time to make the device as secure as it is versus spending time to create lines of codes for a phone that wasn't really designed for 'audiophiles'. But still, i see your point.
For me, it doesn't bother me much as i have a few DAPs. So if i want better SQ, i'll used them instead.
It's not a coding issue. What determines sound quality is the following:
-- quality of the Digital/Analog conversion chip (DAC)
-- quality of audio amplifier
-- quality of all wires and connections in the analog path, including the headphone jack
-- Minimizing radio frequency (RF) interference within the device (This is very complex and affects the entire design.)
-- Ensuring consistent current and clock timing for the entire device
All of these optimizations require the talent of audio engineers in order to balance the tradeoffs intelligently, and virtually no mobile phone makers do a good job of it, though Sony comes closest, as they have that talent in house. BlackBerry used to be the best, and by a wide margin, but that ended with the Passport.

I agree with your pointers, but coding in the OS also has an impact in SQ. I have several DAPs and an OS update does change the SQ.
The reason why i focused on the SW side is that BB was never known to be an 'audiophile' grade phone. So it's a lot better for them to spend the time and effort on making sure their OS is as secure as it can get versus to trying to make it sound better.
I agree with you that it's not strategic for them to focus on audio quality in 2017. But it used to be something they were very good at. Not "audiophile" quality, but very good.
I haven't seen any smart phones from any manufacturers, other than Sony, in the past 3 years that are as good as the Passport was.

Sorry about the bodged posting
The Keyone is average within the group tested above until headphones are plugged in, then it becomes one of the worst listed there.
Interesting...assuming the test data is accurate, and aside from a few obvious blips...most of the devices (including the K1) seem to fall within line of each other, for the most part...even down to a few hundredths or thousandths of a decimal place. Are these minuscule differences even perceptible to the human ear?
Might as well just go by what just plain sounds better. If there is a significant difference as you say...maybe it's just me, but I can't see how anyone could make a decision about SQ based on numbers like these?
The upcoming Keytwo with the SD660 might be something to look forward to:

Qualcomm is the main reason that audio quality is so poor in the current crop of mobile phones. I am very skeptical that any Qualcomm platform that doesn't employ chips from Cirrus or another dedicated audio processing company will sound any better.
The reason that BlackBerry used to be so good is that they employed the Wolfson DACs. When BlackBerry 10 hardware failed to sell, Wolfson was sold to Cirrus Logic.

Many thanks for this info!
By the way, how would you rate the sound quality on a Galaxy S7?
You picked the two BlackBerry devices with the best sound quality -PlayBook and Passport- for your comparison. Unfortunately, and this is in my experience only, no phones compare to the sound quality of those two. But YMMV.
Agreed!! I think the listening device's output is also equally important! I use QJAYS iem's and the sound is amazing!
Lately i'm being too lazy to use DAPs, the K1 would do for now - it's 'ok' or to be more precise - acceptable as an audio source.
Actually, the Z10 with the Wolfson DAC is also very, very good. I assume the Q10 is the same.

Yes. I think those of us who have been BlackBerry users over the years, particularly in the BBOS(7) years were spoiled with call and speakerphone quality in general.
Always amazes me when I read or watch a review of (any) phone nowadays, all that’s discussed is camera and multimedia quality. Very rarely does someone comment on the call quality. Aren’t these phones?
Oops mods please remove the duplicate post of mine. :) thanks.
Thank you for this tip. It made a HUGE difference.
That's super cool I had no idea that it improved the overall sound of the device as well!
