Stereo Quality Anywhere and Everywhere 

Ready to kick your music up a notch, even on the go? Our Sony PHA-3 High-Resolution Headphone Amplifier is perfect for the job. It brings stereo-system amplification to your headphones in one easy, lightweight package. Enjoy incredibly rich, quality music -- no matter where you are. 

Made from Tough Stuff 

Built to withstand the rigors of portable life, the PHA-3 features an extruded aluminum enclosure, the better for protecting delicate interior circuitry from impacts and outside interference. It also sports a fully-integrated front and rear alloy end-caps, the better for protecting terminals from hard knocks. Plus, its recessed controls reduce chances for accidental access during playback. 

Never Stop Listening 

Listen on -- and on -- with its built-in, fully-rechargeable lithium-ion battery. It’s good for 5 hours of balanced-audio playback when connected digitally via USB -- or for a whopping 28 of them when connected with the traditional analog ⅛” stereo input (headphone jack). This Sony headphone amp allows you to finally listen to a great performance the way the artist intended. 

Connect to Literally Anything 

Connect between your music source -- smartphone, tablet, MP3 player, and so on -- and your headphones to truly enjoy the rich, Sony quality sound previously only available on your speaker system. Or use the built-in array of connections to its fullest! With an analog audio output, the PHA-3 connects direct to your amps or your speakers. And with three USB ports -- two micro Type B’s and a standard Type A -- connect your computer and enjoy rich, full sound. The perfect add-on to mate your headphones with your brand-new iPhone 7. 

Imagine Richer Music 

This isn’t just a portable amp! It’s a Sony amp outfitted with their latest Digital Sound Enhancement Engine (DSEE HX) technology. Revitalizing high-frequency audio response, it’s perfect for listening to your HD audio library. Plus, it upscales all of your other signals -- your MP3s, your AAC, ATRAC, and WMA files -- to true high-definition audio. Enjoy the difference a good amp makes. 

Perfectly Responsive 

With a built-in asynchronous USB clock, the PHA-3 supports extremely accurate digital-to-analog (DA) conversions. The ultra-precise clock reduces timing inaccuracies when converting digital 1’s and 0’s into analog wave forms. This results in superior audio with minimal noise and distortion, all the while maintaining sound stage-integrity audio response. 

Balance Your Audio 

Check out the bottom of the amp; there are three input jacks. Why is this? In a home stereo system, you have to connect speakers separately to your amp, feeding your audio signal into left and right channels. Not only do you have a jack for normal headphones, but the other two jacks allow you to use balanced audio-capable headphones, such as our Sony MDR-27s. 

Rethink Your Headphone Audio  

Able to comprehensively decode pulse-code modulation (PCM) audio sources -- such as CDs -- and direct-stream digital (DCD) ones, the PHA-3 is able to deliver a truly high-resolution audio experience, straight to your headphones. Thought their sound was rich? Think again.
