Conclusion: The Pioneer A3 (XW-SMA3-K) is probably the most versatile wireless streaming speaker we've seen—it's even portable, rechargeable, and water resistant—but it doesn't sound like a $400 system.
Pros: Powerful audio for the size. Streams wireless audio via AirPlay, DLNA, HTC Connect, and Wireless Direct when there is no Wi-Fi signal. Water-resistant, portable, with rechargeable battery.
Cons: Distorts on deep bass tracks at top volumes. Very slow to power up. Overly complicated controls, and set up process is not terribly intuitive.
Conclusion: It’s obvious by the traces of Andrew Jones’s signature all over the SMA3 packaging that Pioneer is proud of their acclaimed speaker engineer, and they should be. The sound the SMA3 reproduces on most styles of music is nothing short of phenomenal. Naturally, it has some sound limitations, because let’s face it: It’s a tiny little box that you can carry anywhere.
