Summary: This excellent unit of wireless (except power code) and it supports latest technology like dlna and airplay. Easy to to setup if you have some very basic knowledge about your wifi router. Also it supports direct wifi that is we can say it is truly a future proof device. Direct wifi will replace bluetooth technology very soon or so.
Summary: This portable speaker wifi device produces excellent balanced sound from such a small enclosure. I am a long standing Hi Fi enthusiast from Quad II tube amplifiers (1960s) all the way through to today's technology and these portable speaker systems are quite amazing; but there is a much competition to choose from. I wouldn't hesitate to put this system up against the best of the similar product offerings from Bose and B&W, and NAD.
Summary: My daughter researched all the similar speakers and decided on this one. I bought it for her for Christmas and she couldn't be happier. She has called me several times raving about the quality of sound it produces and she is quite the audiophile.
Summary: This system is incredible. The firmware update from Panasonic adds self hosted Pandora and Spotify (through the Pioneer Control App) which is really good. It will keep playing without the pandora or spotify phone app running because the device acts as the client! It is a very responsive system. It's physically beautiful. It's a great DLNA player which pairs perfectly with my Synology (through Audio Station). I love the way this works.
Summary: I received my SMA4 today and I had it out of the box and connected to my home network in less than ten minutes. I used my IPhone 5 to make the connection and my MacBook Pro also found the connection right away. I am impressed with the sound quality. It definitely can fill up a room at even relatively low volume. The speaker would be a great buy at an even higher price.
Very Good product. My first one didn't work at all, but was able to return it for a replacement. It works great.

Summary: Easy to set up, easy to use, great sound. Very good after sales care. My comments limited to the WIFI use case (since I don't use the others) but it's very flexible and supports many different connection modes.
