Sound technically simple a bomb similar to the SoundLink, bassy but not quite as strong, but clearly emphasizes what is useful in the field.
Battery life is specified with 8 hours, which is achieved not only in a whisper. Under full load to reach incredible 4 hours, which is sufficient to provide sound a 40sqm room party default.
Bluetooth connection very easy, but for technical reasons, susceptible halt when no visual contact. Alternative connection possible via Aux.
Services such as Spotify, Xbox Music, iTunes OAE. can be super on cell phone, Mp3, use laptop etc.
For all the flirting with the SoundLink, like me, I can only recommend this device to look and if you like it is priced a new iPod Touch on top of it!
