Why the sound at first was not good, and now but for the size has a more than decent sound and a good volume level, to me is simply a mystery.
Conclusion: Anyone looking for a mini speaker with built-in battery, which is really tiny, easy to store and in all walks of life provides a good sound, could be happy here. I for one am glad that I have not thrown the ROGNT after first trying them out on the wall, Segregate the Knilch've left a chance. Meanwhile, I want the little nub that is not to miss in my household. 5 stars and a buy recommendation.
