Sony’s Sound quality is there, but the problem less power output from the headphone jack.
And why haven’t they gotten the problem ruled out yet? As far as I remember, their phones have had a good quality, but so damn quiet audio output on headphones. The problem has been the same for YEARS. Or do they just ignore it? If they are known as the "go-to" phone for audio, then I’m not expecting anything else than the HTC-level of audio quality and volume on headphones as well.so.
The answer is simple, they have Walkman players selling separately . I have Z3 compact and Walkman e574. I can tell the sound quality difference between them. So don’t expect too much volume output from Sony
