ZolaIII, 21 Apr 2020Tiristor based impedance to voltage regulation is better approach if you must have one, CS431... moreSix months back I bought a Meizu 16th (Meizu 16 in China). At $240, it was a flagship with SD845 & 8GB RAM. Meizu India provided a fully Google certified device with Google playstore pre-installed. In short, pretty awesome performance & built quality for its price.
Meizu has a rich history of making portable music players before they ventured into smartphones and still today makes some very good quality headphones & earphones. As such the company understands sound quality and many of their previous flagships smartphones came with dedicated DAC solutions. However for 16th, sadly their last flagship with a 3.5mm audio jack there was no press material indicated anything extraordinary in the audio department.
I took for granted it was using some low quality audio codec from Qualcomm. However more I listened music through my Meizu 16th, more I fell in love with this device. One day just for fun I sat down a did some critical listening with some expensive earphones, and I immediately noticed the sound quality is above ordinary through the 3.5 mm headphone jack. I started reasoning my mind how is it possible with Qualcomm codecs and Meizu must have done something special.
After going through some Chinese websites performing detailed tear-downs, I found Meizu 16th is using the highest quality flagship audio codec available from Qualcomm. It is Qualcomm Aqstic WCD9341, a dedicated audio chip. With an advertised dynamic range of 130dB & distortion of -109dB during audio playback the WCD9341 is quite close to ESS Sabre ES9218P (LG's Quad DAC) & Cirrus Logic CS43199 (Vivo NEX S). Digging deeper I found Qualcomm partnered and further tuned their flagship WCD9341 under the guidance given by a group of audiophiles known as "Golden Ears". Qualcomm was then able to create custom digital filters which creates the final sound signature which are generally adored by most audiophiles.
However in real life even if these objective measurements are very close to ESS & Cirrus Logic, there still remains a gap that Qualcomm have to fill to the very best in the audio industry. In Meizu 16th tear-downs by Chinese media, I found the WCD9341 audio chip sits under its own tiny metal cover plate with graphite & copper shielding over it. So the chip is completely isolated from the rest of the PCB and its ICs. This complete isolation definitely eliminates a lot of induced noise on the analog stage of WCD9341. Quite impressed as Meizu shelled more money in the production line to make sure the sound quality remains intact through the 3.5 mm audio jack.
The other fact I noticed on 16th is the power available through audio jack is much higher than similar WCD9341 implementations like in OnePlus 6 (sadly the last OnePlus with audio jack). The OnePlus frankly sounds anemic in comparison to 16th, no drive. Meizu seems to have twice as much power and can drive any headphone much better.
Going through the spec sheet I found WCD9341 is designed to perform with power anywhere between 6mW to 34mW, maybe Meizu is providing all the power it needs by dedicated power rails. In short I am truly impressed by Meizu's dedication for sound quality as I see & hear the difference of the same audio chip with drastically different performance levels between Meizu & OnePlus. It is Meizu's good implementation that make the WCD9341 shine. Correct me if I am wrong LG's QuadDAC consumes 2.5 times more power at 80mW but have way more drive capability.
Subjectively, Meizu 16th sound signature is like my LG V30+, which can be best described with words like pristine, neutral, clinical & accurate. However to my tastes WCD9341 easily beats anything from AKM stables, be it AKM AK4376 or AK4376A in sound quality. Drive capability is more or less same.
One of the other reasons I bought Meizu 16th was dual stereo speakers. Each speaker is powered by a dedicated Cirrus Logic CS35L41 amplifier, so sound is loud & crisp leaning more on the musical side rather than being out and out loud.
In the end I am quite impressed with the sound quality and headphone drive capability of Meizu 16th through 3.5 mm audio jack considering that it still uses an audio codec from an unknown brand like Qualcomm in the audio world, though I admit the audio codec is of high quality. Qualcomm deserves credit & also Meizu deserves a pat on their back for bringing to us perhaps the best implementation of Qualcomm Aqstic WCD9341 in a smartphone till date.
Aaron, 22 Apr 2020dac have only lgAs stated in this discusion ... no, there are few other that use dedicated DACs to drive their outputs - LG is just the most "famous" one :D
There were many phones with Wolfson DACs, it's really a shame they all died out.
CAw, 21 Apr 2020So which phones have "Dedicated" DAC? I want to know more, please!dac have only lg
Shitter, 21 Apr 2020How did you write this? With your pen?Bro bro bro bro!!!! Woaaaaahhhhh!!!!!!!😂🤣
Anonymous, 19 Apr 2020I do not feel that there are advantages over v50 besides main cam and battery endurance. Today I played with V50 with fresh android 10. It is just brilliant. Yes battery and cam is main pros to V60 over v50.
I just recieved my LG V50 5G with android 10 and I gotta tell you! There is NOTHING better than LG Android 10 UI. You gotta see it it is amazing. And I have mate20pro with android 10, and p30pro with 10, and LG v40 with android 9. But v50 with android 10 is something else!
Gotta love LG
V60 is the same or better in software wise

I know the creator, successor with lot of thing's resolved better (digital filters, companion app, multi layer PCB, better interface USB IC...) is coming really soon. He is a pain in the ass and I hope successor will have & normal unbalanced out but I don't hold my breath on that.
A nice balance of tech. I like that this V60 doesn't focus on just the camera & offers more with nice video & audio features also.

Even for a... moreYou should try E1DA 9038S, for 80$, this one beats DragonFly Cobalt and it's very light, just 10g. All you need is a Type C to Type C dongle and a balanced output 2.5, seriously, a lot of audiophiles recommend this one.
Hey can anyone here help me.. I'm a poor man from Egypt and all what I hope is to have any mobile phone for free so can any one help me in that
RishiGuru, 21 Apr 2020Aah.. the ZTE Axon 7 with AKM AK4490EN audio DAC. I always wanted to experience this phone, bu... moreTiristor based impedance to voltage regulation is better approach if you must have one, CS43131 for instance take it. Best approach is ideal gain delta hard limited in design for all amplifier elements and analogue control at one end of the chain especially taking in consideration & DSD. I already tried to tel you how DAC's sound the same & everything else is related to noise and distortion this is related to how good IC is made along to how good it's implemented.
Second part would be actual matching, he tried to explain you the part with output impedance the Amp has as if it's let's say higher than 10 Ohm's it will charge sound characteristics for sensitive lo impedance EMI's for which desirable is under 1 Ohm's & 120 dB SNR. So that's step one amplifier, second would be an OP Amp & Amp with gain switch (again vvd related) for 80~120 Ohm's on lo gain and 150~300 on high gain. By the way LG's lo impedance gain limitation is software one & applies only to EU - US firmwares because thay actually had to do it to comply to the law and regulations.
LDAC at high quality 24 bit 96KHz @ 990 KB/s actually stays in 17 bit range. Think Opus is next logical step for BT audio.
I feel that the whole tech world don't NO what they are talking about, if a phone is lacking in addition to screen or camera specs. Its a lower speced phone to all the competition.WHAT NONSENSE LG , HAS EQUALLY As much functionality at Samsung, more than oppo or One plus and Apple. But due to it not being popular its not counted.every manufacturers stands out in something.no brand is good at everything.Thats a fair comment or narrative that should be pushed. LG HAS A HEADPHONE JACK, WITH EXTRA AUDIO FEATURES. IT HAS MANUEL VIDEO, IT HAS WIRELESS FAST CHARGING, IT HAS 8K MANUEL MODE, PLUS EXTRAS. Now Samsung and oneplus or apple are lacking in some of these these features, yet they are counted to have more due to what a smoother screen experience and a 2k display, which LG pioneered.Look I'm not brand loyal, but I like to give credit where its due Lgv60 has given users the 2 most important things when it comes to mobiles and that long battery life and good audio to hear people on the other end. Who cares about 120htz or 90htz.

I always wanted to experience this phone, but alas it never got released in India. However I am well versed with the sound signature of AKM's. I own a Vivo V5Plus with AKM AK4376 and they sound lush and sweet over the audio jack. Emphasis is always on low to mid-range but the overall balance throughout the entire audible frequency range is quite good. However they are not as accurate, clinical or precise as ESS ones found on LG's. AKM, Cirrus Logic, ESS each have their own style and I love them all.
I don't like the current three step gain output structure of LG's QuadDAC, as the first step on low impedance cans (< 50 ohms) sounds anemic. Not earphones mind you. Tricking the QuadDAC to the second step will provide meaty power.
On other hand I have seen over powering low impedance headphones can provide detrimental effects to over all sound quality. Hence I prefer the 2 step gain used by Cirrus Logic in my Vivo NEX which provides the sweet spot of ample power to drive any proper headphone and you do not need to do any kind of trickery. Same for Axon 7.
Bluetooth headphones are no doubt far worse. People who don't understand audio, audio quality & audio technology always speaks about BT headphones are the way to go. Yes for convenience factor BT headphones are ok, but not critical listening.
Can they make it a bit smaller with 4500mah battery? This is quite big. And how about updates in India...they suck at that
youtindia, 19 Apr 2020The sudden removal of headphone jack testing makes no sense at all. Why remove something that ... moreSlowly conditioning people to a wireless future. Just like what Apple did.
Make 3.5mm jack look bad.
Anonymous, 21 Apr 2020Xperia 1 has 689 nits. Lower pixel density makes easier for the company to increase brightnes... moreHaha, the panel is dimmer compared to other flagships.
Besides, I'd rather have a 3k panel pushing 1200 nits than a useless dim 4k panel.
Oled burn in happens not coz of higher brightness, it happens on cheaply made oleds after the pixels are static for too long(unrealistic in the real world).
SD865 may not support 4k@120hz but it can support 3k@120hz or even 1080p@120hz.
Why Sony not giving that option to the user? All I see are excuses after excuses made by Sony fans.
3x optical zoom that they provide on Sony is useless. Same result can be obtained by cropping from Main sensor on other higher megapixel cameras.
When I say periscope zoom, I'm talking about 5x,10x optical zoom which is standard for 2020 flagships and is super useful. Portraits aren't the only thing you shoot using telephoto lens.
S20 ultra is the current zoom champ. Great pics thru telephoto lens (day or night) without any compromises. Extremely useful during videos as well without losing that great image quality.
"Chinese brands use two batteries to charge faster"
>> So? End result is faster charging without the associated heat of 65W charger.
Besides, Only Oppo using two batteries, rest are using single batteries.
" It is proven faster charging will decrease life span"
>>That is true only if excessive heat is generated.
Learn how VOOC and other technologies work. Chinese brands way ahead in this department. VOOC keeps heat away even when charging and using your phone. Sony Quick charge is different tech and is inferior to proprietary Chinese fast charging tech.
While companies like Xiaomi using better batteries with more charge cycles despite faster Watt charging, while Sony choosing regular and smaller batteries which eventually end up consuming more charge cycles and start degradation after 300-400 charge cycles.
Sony simply charging more for bigger profit margins.
looks promising, but again, GA drop some test off, this time ausi lab test, why!!
do it plz.
Anonymous, 21 Apr 2020Sony is cutting a lot of corners too.
Dim panel, lack of higher refresh rate out of the box.
... moreIt is not a good deal based on a specs compared to competetion, BUT specs alone do not tell the whole story.
If the cameras are much better than Xperia 1/5 ... and they should be - they are using better chips and better glass ... I would be more than willing to shill said amount of money for a phone with 60Hz display, (I don't care for 4K on 6,5" screen, nor do I care for 60+Hz on my personal phone), headphone jack (even typical low Sony quality), improved mics over 1/5, bigger battery etc.
Why? It does not have a notch, I like Sony speakers, I like their colour balance and the way they are implementing noise reduction, I like it has SD card slot, headphone jack etc. the only thing it is missing in my eyes is a propper desktop mode, BUT considering the quality of Sony software it could actualy be better that way.
Sonys phones are not a good deal to many users and I feel this year It will be even more apparent.
