The optics of flips has managed the workmanship is good.
Unfortunately, the sound quality is not convincing - in mid volume of the sound is quite ok but not good. Set quietly whispers the box without pressure in front of him, at full volume sounds the flip very plärrig. Bass there, but punchy is different. He can not prevail.
In no volume I have to hear to feel a "grown-Box". That's something many other mobile box succeeds entirely in this size class.
Who is a very handy little mobile box examines the "really loud" may, should resort to flip. Those who place a higher priority on the sound, should resort to other models.
