Out of my phone it sounds like rubbish, but improves when I use Viper4Android and tweak the gain and DSP settings. Sounds good, but thin from the Aune T1's amp, like it's lacking power. When fed through the FiiO E9 and Vamp Verza they sound full with powerful, rumbling bass and an open, airy sound. The RealTek chip on my PC's motherboard can barely get them loud enough on full volume and sounds congested and sloppy. The Sound Blaster Z gets it plenty loud around 40% volume, presents decent bass, but it's not as lush as from the E9 or Verza. The treble is bright, clear and a little drier sounding. More analytical.
I heard the stock tubes on the Aune T1 are kind of iffy though, and that it's a gateway drug to tube rolling.
