Default USB Audio - working!

Hi everyone,

I know this has been confirmed elsewhere on the net, but I didn't see anything here so thought I would pass this on to the more hardcore audio fans here.

I tried all my USB DACs last night - RSA Intruder, Apex Glacier, HeadAmp Pico, Leckterton UHA-6S.MKII and all are working with the Xperia Z.

I recently got the MW1 (only 19!!!) and learned about DACs (apparently there's a pretty good one inside, Wolfson). Now using this together with the MDR-1R and my Xperia Z! Really nice.
The DACs you are talking about are standalones? How would you use these and why? And why so many? Sry noob questions, but would really like to know.

Yeah, standalone DACs/amps. You would use these because they give you better sound quality than the phone itself does, and also the amplification makes them able to drive less sensitive headphones, which phones are unsuited for. Now that Sony, HTC, and Samsung all have USB audio in their phones it means I never have to care how good or bad my phones inbuilt sound quality is, I know I'll always have awesome sound quality regardless.

As for why so many, well, no particular reason apart from I wanted to know which I liked best and I'm taking my sweet time about deciding!

Where did you get it for 19 euros from?

It was a temporary offer from Studentmobiel, the dutch company where I ordered my XZ. Ridiculously good offer

Thanks for the explanation.

What do you mean by less sensitive headphones?

If I understand, newer model phones all have a DAC inside already?

In my case, because there's a Wolfson DAC in the MW1, would you recommend using MW1 or just using Xperia Z (in the case of audio quality) ?

Audio PlugAndPlay

Is it a simple plugAndPlay or do you have to restart the phone with the DAC plugged in?

Would love to attach a Behringer X302 to my (future) Xperia Z
It's only 42Euro at Thomann.de


According to the Android App USBAudioRecorderPRO
i can record a signal with the Xperia Z (hopefully)
Think that output is also possible?

Simple plug and play, USB Audio Recorder Pro not required.

All phones have a DAC inside, a DAC is a digital to analog converter, and is required for the playback of digital music and sound.

The advantage of bypassing the phones internal DAC, which is what is being done with USB audio, is that if a phone has a poor DAC (or good DAC that is poorly implemented for that matter) you're not stuck with that.

Headphones and IEMs have varying sensitivity to a given input signal - some require more power to drive effectively (and when I say drive effectively I mean drive to both good listening volume levels and adequately control the driver of the headphone to get the best from it). That's a fairly simplistic and ham-fisted explanation right there to get the basic gist across, if you really want to understand 'sensitivity' you should take a look at somewhere like Head-Fi and so some reading about sensitivity and input impedance (for starters). As a general rule IEMs tend to be more sensitive than full-sized headphones.
