Summary: Best sound, very cool style. The power of bass and treble is incredible. For those who wanna pay higher prices for excellent quality and style. What's not so good is that it doesn't come with a rechargeable battery, you have to use your own batteries. And also it's weight, it's a little bit heavy but it's handle makes it still easily portable.
Summary: While sound is pretty good, the player is no where close to portability unless you have "portable" generator to feed this thing up. I inserted the batteries, and all I've got was just "On" button lighting up. That's it, no sound, no response from other controls. I called Australian distributor (I am living in Oz) to check whether this is normal, only to be told that "they are not providing technical support for the items bought outside Australia".
Summary: This is NOT the HKGOPLAY5BLK. They keep sending the Go Play 2. The Go Play 2 sounds AMAZING until you pull the power cord and "Go" on the batteries. You loose half the bass and a third of the volume. Very disappointing! I have returned two and number three is the same.
Summary: I basically wanted a compact music system which i can play and able to move it to the place i need. So this perfectly fits my requirement. Coming to the sound quality, it is excellent. Even at high volume the music is clear and it has good balance of bass.
Summary: I love the sound quality, but the volume is not up to my expectations of harman kardon. I had sound of the theater speakers in the past, and they rocked. I expected BIG sound and didn't get it.
