Wonderful little device. Use this mostly with a Google Nexus 7 2012 model running CM. Sound from my tablet is now so much better with this little dac. Have also tested it with laptop running Win 7 and a Chromebook, no problems with either. Considering what I paid for this it's been one of my best bang for buck audio purchases.
I'm not ready jet for appreciate the sound quality improvement, maybe it sound more detailed and wide. But the first thing i really appreciate it's that i can turn off the volumen near to zero and the sound quality continues being great.
Works perfectly plug and play with OSX and Windows. Inability to control volume with software mixer is a good thing, means the stream is bitperfect regardless of volume setting. Measures transparently and sounds great. Only downside is the flimsy plastic shell construction, but what can you expect for $30.
This DAC works perfectly with my galaxy note 2. The sound is very clear, detailled and punchy. It sounds better than others Dac more expensive. If you're not completly satisfied with the sound quality of your Android phone, you should try this Dac and you will be surprised !
Have been using with my S3 phone for a couple of weeks now - very solid and sweet sound compared to native output - this is great product for mobile sound...
