I befeuere the Go + Play with android (WinAmp Pro) and MacBook Pro (iTunes) via Bluetooth with MP3's the / s compressed with 256 and 320 kbit. The coupling works fine and the sound is top even with this lossy constellation. So you do not miss when traveling to high-end home theater system. Batteries (Duracell) hold at low volume by about 20 hours, if you then times has no electricity. And last but not least it still looks good no matter where it stands.
2015-02-15 Have happy since purchasing with classical, jazz, rock and roll, Hard Rock and Soul the device. The sound is especially in songs like Gregory Porter's Spirit or Liquid Mambo Sinuendo of Ry Cooder is a pleasure, whether through Bluetooth or the audio input. The equalizer of the player you need only if you want to produce the individually preferred sound pressure. Otherwise Go + Play.
