If you switch the unit on, you will be welcomed with light blue lettering HI, the device then switches immediately into the Bluetooth operation. Pairing works quickly and without problems. Off you go. The volume at power-on stage 9, still has game up, but is quite loud. The sound is decent for a small Bluetooth, however, bring the three membranes (two round, shiny left and right, an oval centered) no real bass with it. So lacking in about Summertime by Fitzgerald / Armstrong of the bass, midrange and treble sound good while about the trumpet. Even songs like Sunday Bloody Sunday by U2 or the marching Violent Hill by Coldplay missing something dynamic. But our previous Bluetooth speaker JBL Flip can do better, sound in direct comparison also fine he resolved also costs about three times. It is important that one seeks his individual favorite sound with the sound settings of player (the Galaxy S5 JAZZ sounds like my best impression).
The EXPOWER but is not limited to playing Bluetooth music, but it actually is a clock radio handsfree MP3 player speakers. If you select the FM function and start the search process, the device is remarkably fast and accurate available stations. Then you can cycle through the many preset stations, however, the case of the mass (Berlin area) may take a while until you have your favorites. Is absolutely amazing how the device with no apparent antenna accomplished noiseless, clean stations cons gifts that I have experienced in other devices with wire antenna so rare. The device can also be used as an alarm clock, you can specify it via the USB slots also have a favorite song that he plays reveille. As mentioned, it can also serve as a hands-free mode and play via the USB slots different data formats. In standby the unit displays the time that you have to set it manually. When charging the details are somewhat contradictory. Point of connection and the instructions on connecting a charger with 5V, there is a hint in the manual that one should not use devices with output power over 4.2V. I could discover none at 5V in my household among the many chargers, the charger from the Galaxy S5 with more than 5V but I'll rather not use.
One shortcoming that I've found is the assignment of certain keys with multiple functions. In particular, the change in the volume (press longer) results regularly is that the title is geskipped or from early starts (press briefly). Here I would have nothing against separate volume buttons. Class endurance, however: Even after three days use, each about 6 hours of play time at moderate room / office volume, the device is not yet empty that does not stop the FLIP rudimentary.
Conclusion: The functional diversity and perseverance make the EXPOWER a versatile travel companion and it can also replace the bathroom or clock radio. The sound is not for the most demanding, as musical accompaniment while traveling or in the office but very neat and never annoying. For the current price of about 30, - Euro (as of 09/14), the device is a strong buy recommendation, if you're looking for more than one speaker truly amazing and for me. Only discerning listeners or those who can not do anything with the additional functions, should look elsewhere.
