By connecting the amplifier via USB (for PC and some smartphones like the Galaxy S3-S5) the device to the sound card and the sound is even better again. As the amplifier sounds can be adjusted with a PC or Mac in order to better meet individual needs also a software download from Creative.
Unlike the E1 E3 also has Bluetooth (for wireless connection) and NFC allows appropriate smartphones easier to connect by simply holding the amplifier and the instrument together. Bluetooth is flexible, but also comes at E3 not match the quality of a cable connection.
In addition to the audio reinforcement of E3 can be used as a speakerphone and allows even in demanding conditions such as windy weather still clear calls. All important functions for controlling calls and audio playback are also from the E3 of reach. Who can do without Bluetooth but should look at the E1 because it is again more compact and easier to carry.
This amplifier is also very good if you go once his own music simply want to connect to an audio system, after all, has today almost always the personal collection on your phone case. The sound is worlds better because the amplifier brings enough power.
All in all, the E3 once again a sophisticated audio solution from Creative which can be proud of. The unit keeps all advertising promises and offers even more, but there is a downside. Through Bluetooth, the battery life is considerably shorter than in the E1, in my experience, really only about 8-10 hours with moderate use, so who wants to party the night away in between must to the charger. Otherwise, there is really nothing to complain about, absolutely ok for the price and in my test experience I will also give additional equipment, because who has heard good quality on smartphone does not want to miss this.
