I really like the design, which is very minimalist and should blend nicely with most modern environments (106x108x235.5mm for 1360g). A black version would be nice as well, but at the moment, Logitech as shown the white/silver speakers only. It’s hard to tell from the photos, but Logitech has placed the volume control at the top of the Right speaker. The cables that power the speakers are “lay-flat” cables that don’t get tangled up. It’s the same kind of cables that comes with slightly fancy headphones these days.
Up to three devices can be connected at any given time, out of 8 that can be paired with the device. The user switches the source audio via a button at the top of the speaker. I haven’t listened to it, so I can’t vouch for the sound quality, but the Logitech Z600 ($149.99) has 3 drivers in each speaker so, it should be pretty decent for a set of computer speakers.
