Volume levels are fine. I listen with my MDR-7550's and if I turn the volume up all the way my ears really hurt.

I really wouldn't call the audio volume low atall. It isn't the loudest by any means but it is loud enough and certainly isn't low.

Those things usually just make bad things worse.

Thing is how loud/good does it sound on it's own internal speaker?
GSMArena in particular are saying it's got a really poor internal speaker

^We are talking about the headphone volumes here..so discussing the DAC..It has nothing to do with the external speaker. Though i have heard its pretty good..not the loudest though.

External speaker sounds good but doesn't go as loud as most phones. Still adequate for pretty much everything though.

I had a listen to a demo unit in phones4u today, can't say i'm impressed. I stopped using my SGS2 for audio because I couldn't stand the poor sound quality and the XZ is not a lot better. I know it's just a phone and a standalone player will always be better, but it would be nice to at least have a phone music player that is listenable!

I did a side by side comparison. The XZ was able to drive my AKG headphones a little better than the SGS2, the bass was a little warmer and mids were possibly a touch less mudded, and I can't comment on if the antenna radio buzz is still present because obviously it wasn't connected to the network. Really disappointed, was going to preorder my upgrade today, but not now. I'll wait for the HTC one and SGS4, then demo those before I decide on my upgrade.

If the rumours are right then both the HTC One and SGS4 will use Snapdragon 600's, which most likely use the same DAC and everything as the Xperia Z - so they'll probably sound similar too.

There just isn't enough internal space to add a proper DAC and amplifier that really offers better sound quality. And nobody really cares either, I call myself a mild audiophile, have a lot of high-end dedicated players and IEM's and the difference between using a good player and my Xperia Z is actually not all that big (at all).

If you really want sound quality while on the go you need one of these:
http://pro.sony.com/bbsc/ssr/cat-aud.../product-PHA1/ - they work with the Xperia Z.

Hi Forsh, as Ambroos said, the output is too weak to drive headphones well. The only solution would be to carry an external DAC/amp, or to go with IEM.
Also, SQ and volume are two different things.
Headphones usually have higher impedance than IEM, therefore they will get less power (lower volume) on a low-voltage audio source.
Sound quality depends on several factors, among which RF/EMI noise isolation and DAC quality.
We said earlier in the topic that the DAC was OK, refering on N4's SQ. We also said that the output was low, which would explain why the music you heard in your headphones was muffled.

Yeap, I know the difference between SQ and volume, i've been an audio enthusiast for far too long! I carry around a Fiio E7 amp (nice cheap little amp, I can highly recommend it) with my phone when I have used it as an audio player because of the higher impedance. On this occasion I was just testing to see if the amp on the XZ naked could drive my headphones any better than the S2 naked (I hate it when the amp battery runs out in the middle of the day).

And then the rest of my post was just talking about my personal impression of the sound on the XZ. Like I said I know its just a phone, but it would be nice if focus moved away from improving quantifiable addons (like the camera) and maybe squeezed a little more out of the SQ side -but what can you do!

One thing i've learnt about discussing how something sounds is that everybody hears things differently (especially when discussing over the internet!) - one thing that's great to one man, is awful to another. I just found the XZ to be lacking somewhat, which is a shame for a such an expensive phone produced by a company that has audio as one of it's central signature products. But each to their own, if you're not using high(er) end headphones and high quality mp3/flac then the phone is unlikely to be the weakest link in the chain, and the majority of the public won't be using either.
