- 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.10-31-17 09:48 AMLike 0
- 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...10-31-17 10:19 AMLike 0
- 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?10-31-17 10:23 AMLike 0

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.10-31-17 10:26 AMLike 0 - 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.

-- 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.
Posted with my trusty Z1010-31-17 11:26 AMLike 0 - 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.)

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.10-31-17 11:39 AMLike 0 - 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.

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.

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?10-31-17 08:00 PMLike 0 - The upcoming Keytwo with the SD660 might be something to look forward to:

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.

https://www.qualcomm.com/products/sn...obile-platform11-01-17 12:26 PMLike 0 - Preliminary listening notes with a variety of recordings and headphones (No headphone amps or external DACs):
The KEYone is significantly less musical than either the Z10 or the Passport. In particular, the lower midrange, where most of the warmth comes from in acoustic music is dry and clipped.
Amplification has never been a strong point for BlackBerry 10 or Android phones. The Passport is the best in this area, with the Z10 second and the KEYone just a bit quieter than the Z10.
Overall, I'd give the Passport a solid B+ on its DAC performance, the Z10 a B-, and the KEYone a C to C-. By comparison, a computer with external DAC /amplifer is capable of A- quality, and an iPhone offers C+ quality to my ears. (I was trained as an orchestral musician and have played live music as a hobby for 30 years, and I've listened to almost every piece of high-end audio equipment under good conditions.)
But don't take my word for it, listen for yourself. Just make sure to normalize the volume between devices before serious listening.
I may post more notes later, but the KEYone is worse than the iPhone, which is saying something because the iPhone is, ironically, a lousy device for listening to music. The one saving grace of the iPhone is that it's loud, while the KEYone is mediocre in both sound quality and quantity.
TCL seems to have grabbed the cheapest DAC they could find for the KEYone. Quality audio is one part of the BlackBerry legacy they simply ignored.

By the way, how would you rate the sound quality on a Galaxy S7?11-04-17 08:25 AMLike 0 - Agreed!! I think the listening device's output is also equally important! I use QJAYS iem's and the sound is amazing!11-04-17 10:14 AMLike 0

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?Baritone Astoria and bqik like this.11-04-17 10:53 AMLike 2 - 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.
