Complained of low frequencies, pulled out by an equalizer. The sound is clean, loud but i would like even louder. On ios put the program "mifa music" and in this program select the connection to the column. Next, you can set many alarm clocks (you can on the days of the week) from the iphone, adjust the brightness, turn on the melodies from the flash drive which in the column, volume. In the play market, i did not find such a program, it seems not yet. Took for 3 k rubles. For this money i recommend. Yes, the light of the clock will fade without connecting to the network. And the connected lights are constantly on average brightness.
