tech.pro, 05 May 2016As you said every MediaTek (not MideaTek) or Snapdragon chip sets come with internal audio cod... moreYou have still not answered the most elusive question... What advantages in sound quality does LeEco's CDLA tech bring over regular 3.5mm audio jack smartphones?
Regarding use of additional audio adapter to plugin existing 3.5 mm headphones, it is heartening to find out LeEco have gone downtrend in using the crappy internal audio codecs from MediaTek & Snapdragon chipsets for their Le 2 Pro & high-end Le Max 2. After all their predecessors Le 1 Pro and Le Max used to come with a heavily modified discrete ESS Sabre 9018Q2C (DAC + headphone amplifier) package with superlative sound quality. So as per your information Le 2 Pro & Le Max 2 now produces crappy audio output through this adapter, hence all existing 3.5mm headphones are also going to sound crappy. Very sad. :"(
Do you really think taking out a quality DAC & headphone amplifier package from the phone makes for a better design? And yes cramming the same DAC & headphone amplifier inside their headphones also makes a better headphone design?..... LOL ... After all the 3.5mm jack was never the bottleneck with regards to sound quality in phones.
Let me give you an example of the overall expenses over a tenure of three years:
1) Let say a good branded phone cost you $160. You add quality DAC + Headphone amplifier with 3.5mm audio jack in it at an additional $20, total phone price becomes 160 + 20 = $180. Now, say a quality headphone costs $40. Now due to heavy usage say your headphones last for 6 months. Over a tenure of 3 years, total expenditure = 180 + (40 X 6) = $420
2) LeEco wants you to buy their headphones, so they take the $20 worth of DAC + Headphone amplifier out from their phone and stuffs it inside their headphone. So they are able to save $20 on their phone as it now sells at just $160. But now their headphones are more expensive with the audio hardware stuffed in it, ends up at 40 + 20 = $60 price tag. Over a tenure of 3 years, your total expenditure = 160 + (60 X 6) = $520
Heck, you end up spending $100 dollars more with LeEco phones on the long run!!!! It may be a great marketing policy by LeEco to suck money from us, but a very bad deal for us end consumers.
Personally I least care about internal crappy audio codecs inside MediaTek and Snapdragon chipsets. But yeah... I do know some discrete DACs & headphone amplifiers used in audio centric smartphones with formidable audio performance.
1) ESS Sabre ES9018
2) ESS Sabre ES9028
3) Cirrus Logic CS4398
4) AKM 4375
1) Analog Devices AD45257
2) Analog Devices ADA4896
3) Texas Instuments OPA1612
4) Texas Instuments OPA2604
5) ESS Sabre ES9601
6) ESS Sabre ES9603
7) Maxim MAX97220
So can you kindly reveal us a little more about the DAC used inside LeEco headphones which you claim is of very high quality?
RishiGuru, 05 May 2016Your point is valid in that while using the 3.5mm audio jack the final sound quality will dras... moreAs you said every MediaTek (not MideaTek) or Snapdragon chip sets come with internal audio codecs, you will have no problem to use the audio adapter to plugin 3.5 mm headphone in Le 2 , Le 2 Pro and Le Max 2. You do NOT NEED to buy LeEco's Type-C headphone.
Even if you want a Type-C headphone, there are lots of manufacturers out there manufacturing Type-C headphone. Each of them has inbuilt DAC in itself. You can get any one of them. Better design and more space for other component in phone is better than having a dedicated 3.5 mm jack in phone.
By the way, can you mention the DAC model no. found in MediaTek and Snapdragon processors?
tech.pro, 05 May 20163.5 mm jack has not been bottle neck but the quality of sound you hear in your headphone diffe... moreYour point is valid in that while using the 3.5mm audio jack the final sound quality will drastically vary from phone to phone with the SAME HEADPHONE. This is because different phones have different audio hardware architectures built in it which results in different sound qualities. An audiophile centric phone will have discrete DACs and headphone amplifiers resulting to superlative sound quality through 3.5mm audio jack while another phone may end up using the internal crappy audio codec that comes with every Snapdragon or MideaTek chipsets.
But with recent trio of LeEco phones, we are in trouble the other way. As these phones comes with no in-built audio hardware which gives the desired sound quality, the final sound quality will now drastically vary from headphone to headphone with the SAME PHONE. If only an audiophile headphone manufacturer ever in their craziest dreams think of making a headphone for LeEco, we can end up with amazing sound quality. But that is not the case as we are all stuck with a very limited number of headphone options that LeEco will provide to us on their mercy. So we are stuck in their eco-system and do not have our freedom of choice. Whenever we buy their phone, we have to now buy their headphone.
And as you say LeEco perform all digital-to-analog conversions themselves with inbuilt high quality DAC inside their headphones, may we know the make or the model no. of this DAC? After all how do you know it is of high quality? Just by reading their marketing jargon's? And now as the DACs come inside the LeEco headphones they become even more expensive than similar quality 3.5mm headphones.
I am still not able to understand from your explanations how LeEco was able to improve the sound quality with their CDLA tech over conventional 3.5mm audio jack? The only change that I can see is they have moved the DAC from inside the phone to their headphones so that they can sell both their products and garner more profit.
RishiGuru, 04 May 2016How come a USB Type-C port with CDLA transmission tech have better sound quality than a 3.5mm ... more3.5 mm jack has not been bottle neck but the quality of sound you hear in your headphone differs from phone to phone even with same headphone. With USB Type-C headphones, they directly take digital input and perform all conversions themselves with inbuilt high quality DAC. This will help them to output more quality sound. LeEco has developed CDLA for better sound processing.
I want to buy this phone where can I avail this? Im from Philippines :)

AnonD-531353, 28 Apr 2016Very disappointing thing is that their is no audio jack.It's very difficult for day to day life...Yes, it has audio port.
It gives high quality music output from USB Type-C port using LeEco's Continuous Digital Lossless Audio (CDLA) which is better than current audio port.

can sum1 tell, if they have sold dis phn in China on Tuesday..
why there arent any review out yet..???

Yes, this phone also lacks 3.5mm audio jack and outputs audio through usb.
is it very hard (read: costly) to make a max 5.2" display? after then the body will not exceeds 14.7 cm length?...hmmm curious.
Can any once confim is this once of those phone which has audio out put via usb port
mr. nobody, 25 Apr 2016WTF!!!!!!!....no audio jack......
To me the LeEco's are audioless phones as they comes devoid of any analog audio hardware. They are in reality saving money on these phones by omitting the implementation of expensive DACs and headphone amplifier chips in the phone. They are basically routing the digital audio straight from the cpu to the usb out. To market they need a colorful name, so we get CDLA bullshit tech.
And to prove this point even further they are not revealing any details of the audio chips used inside their headphones.
If battery is of 4000 mh and it support memory card than it will prove better than redmi note 3
