What customers say about "Key Specs"

Sony PHA-1 Headphone Amp

I think it is a great offering. Music sounds better.
What a beautiful sounding AMP/DAC , much better detail and stereo separation than my more expensive portable amplifier.
Good sounding DAC and highly recommended.
Amazing sound quality and even better build quality. It was either this or a new high end soundcard.
This is a GREAT "portable" dac/amp. There are better sounding dac/amp.

Sony PHA-2 Headphone Amplifier

I have the Fiio E17 and E18 and the PHA-2 blows them out of the water in terms of pure quality - built and sound wise.
This amp/dac makes my iPod classic sound much better.
Excellent condition and ship time. Well done!! Best part, it plays DSD! Sounds amazing.
The PHA-2 is the best built, best sounding DAC/Phone Amp I've used.
The only bad thing, is not able to charge battery during the use of Sony PHA-2.

The sound is outstanding! Good weight and size!
Good. Work perfect. Small size of this unit help me a lot.

Sony PHA-2 Headphone Amplifier

This little amp sounds stellar with my AKG K3003 and Shure SE846 & 1840.
Fantastic little gadget. I've used Windows 8.1 with the downloaded driver and J River to play DSD native files.
It works as advertised. Great little amp. Highly recommend.
I love this little amp and I haven't even listened to DSD or DXD files yet. Just a DAC and the Amp make a huge difference with iPhone 5.
This unit does a great job powering higher end headphones. Perfect size and weight.

What customers say about "Features"

Sony PHA-1 Headphone Amp

The on/off volume knob is very sturdy and feels solid like it'll last.
The PHA1 has a better solution for connecting an iPhone, iPod or iPad. I like it!
However it turns out to be fine. Quite compatible with IPC.
Tonally wise, just right, sweet highs, MIDS and low, tight and control bass.
Average battery time for this product should be around 5 hours, however, the best time i got after fully charged is no more than 2 hours.

Sony PHA-2 Headphone Amplifier

PHA-2 has a good warmth compared to Mojo, slightly v shaped and highs does not resolve as well as Mojo, Fiio or Onkyo.
Listening to it right now streaming DSD files, it's awesome.
Love the rubber bands that come with it hooks from the PHA-2 over my I Phone right back to the amp it's got ridges that hold the bands.
Work like a charm with apple ipod touch 5 and the standard cable for charging.
The battery level indicator seems to be a bit off, as one moment after listening for a few hours it will still indicate that I have full charge and then in the next hour it will be flat.
