This is a product that has all good. A powerful sound (for height), with very good scope in both acute than in the midrange and lower midrange. obviously a bit light in the bass, but it's hard to do better for a pregnant this size powered by a battery whose autonomy is more than enough for continuous listening on almost the entire day. Perfect inside and out. Solid, elegant, discreet, stable, ... In short, this mini speaker to it all! :)
