[Question] how to improve audio quality of inew v3?

[zatycz]

listening to music while your earphones are plugged in with inew v3 is not that bad!
I didn't thought that this might make you think inew v3 has the worst audio quality ever! which is not so!

Experts Answere!
so finally is there any hope that by changing the 3.5mm jack I can get better results from this phone?
ONE MORE STUPID QUESTION! :
do smartphones have some specific hardware for audio management? like old pc's that had audio card

Danyno1 sorry, but i have to say, that V3 has really crappy headphones output i saw for last 2 years on smartphones. Yes, if you use some average headphones with low impedance and high sensitivity, you dont need to set higher volume and the sound is fair. But with "better" headphones with higher impedance, you need to set higher volume and the sound is heavely distorted (you can hear it best on bass). I tested it with Sony XBA-3, Sony MDR-1R, Xiaomi Pistons 2.0, Sennheiser IE80 and it was unusable for my ears

No, there is no change to get better sound with changing jack connector.

Yes, some smartphones have dedicated chip, called DAC (Digital-Analog Converter) to get better headphones output, like european version of Galaxy S3 has Wolfson WM1811 and sound compared to V3 is like from another galaxy, even on cheaper headphones.

ATM, there 2 ways to get fair sound quality from V3. You need to use some good player. I recommend PowerAMP with turned on Direct volume control.
1st one is Bluetooth. Tested with Sony MDR-10RBT and even without apt-x support, the sound was very good and much better compared to cable connection of same headphones.
2nd is to use some headphones with Active Noise Canceling. I had borrowed MDR-NC200D and tested it in city traffic, and the noise cancelig was very good, so it wasn't necessary to turn on volume up and the amplifier inside headphones did his job very well.
