Very cute little amplifier. I like the idea that it requires no power at all to run. I was skeptical about this, but it turned out it really works, and the sound got amplified while the volume remain unchanged. You cannot compare this amplifier with a actual speaker, but it does have significant impact to the audio.
This will only work for Iphone 6 / 6S. I wish they can come up with one that allow the iPhone to sit in landscape mode so that I can enjoy a video with it. It also allow you to charge your phone while using. One thing I don’t like about the amplifier is that the home button will be fully covered by it and it is so inconvenient especially when I need to unlock the phone or do something with the phone while listening to the music. But overall, I am happy with it.
