USonic headphone :good: ; Speak is loud
The USoic headphones are really good. Bass is strong. If the ear scan feature is activited, some noise is then introduced as the result of the algorithm trying to balance the sound when you play quiet music like piano ones, but the feature can be turned off easily through notification screen.
The speaker, however, does not produce strong bass at all. But sound is clear, and no cracking even at max volumn. Max volumn is also really high on the speaker. A lot of times the ringtone gives me heart attacks when it is on my computer desk.
It is dual speaker, as in the one you use for phone and bottom firing speaker can both produce sound. However, unlike M9 or previous dual speakers, it is not entirely stereo, and the impression it gives me is that they seems to cover different part of frequency range.
In short, other than the lack of bass for the speaker, I absolutely have no other complains about the sound part of this U Ultra.
