Summary: These speakers are great for providing much better sound than your phone, tablet, or laptop. They are very portable, and provide good sound quality for the size. Only downside is that you can't charge them and play music at the same time.
Summary: I had a set of "original" X minis a number of years ago. Lost them to an ex roomate. Bought these as a replacement, still as good as I remember. Not designed for epic bass, but great as portable monitor speakers when watching Netflix on an Ipad.
Summary: The sound is great and the portability is great. The only trouble with these is that at loud volumes, the speakers themselves would rattle on the shelf because they are light. Otherwise, surprisingly good sound and quality.
Summary: I just received these today and gave them a short audition. At first they would not play in stereo mode using the included charing/playing cable. I was able to get them going using the cable that is built into each unit. I have to say I was pleasantly surprised by the sound they put out.
