Yeah, iPod speaker docks are a dime-a-dozen, but Pioneer’s new XW-NAS3 and XW-NAS5 seem a little better than most. The 2.1 speakers have a digital amp, built-in downfiring subwoofer, and an optional Bluetooth adaptor lets them stream music wirelessly.

Bluetooth being built-in would be nicer, but still, not having to connect to your iPhone 3GS or iPod touch 2G (or other Bluetooth device) is kinda neat.

The XW-NAS5 (pictured top) also has auto track volume levelling, an “Advanced Sound Retriever” to improve compressed music, built-in radio, and a hippy ambient sound generator to sooth you to sleep.

We don’t know pricing yet, but the speakers are slated to arrive this season. The basic XW-NAS3 will only be white, while the S5 will have a few different colours, including red and black. [Pioneer]
