Summary: First off, I have to say I was VERY impressed with the unit. I was at first a bit confused when taking it out of the box on how the control unit was attached to the sub, which houses the amplifier. The power cord was also attached, and both were in a separate compartment so it was difficult to remove. Having flash backs of previous sound systems, I was a bit scared as to the quality (usually low-end speakers are setup like this). I have a nice 5.1 system and every cord is detachable from the main unit. It's nice when you re-organize your room and stuff, but definitely not a necessity.
But I was curious as to how well the sound would be played. Logitech has been known to produce wonderful speakers in the past, and they have done it again with this version.

Setup was a breeze, although I admit I had to cheat and look at the manual to figure out what all the extra dock parts were for along with the extra headphone wire. Learned that the unit fully supports iPod video, and nanos, and the new Zune. Since it does not use the proprietary jacks for the units itself, you can pretty much plug ANY MP3 player to it, and the MP3 rest area is concealable, aka you pull it out during use and can push it back in when not used. The only problem with this is that the \"dock ports\" for the specific units will get in the way if you decide to use them. And then if you do not, your unit won't be charged. So for all those people that don't want to use it for MP3 and just have a nice affordable 2.1 speaker system for your computer, yes this can work for you. No one will be the wiser about the dock, except for you. Only downside to using this as a MP3 sound dock strictly is that if you decide NOT to plug it into your pc, the pc audio cord is hardwired to the unit, where as the MP3 audio cord is a separate add-on. I think Logitech saw this product as a PC speaker setup first then as an add-on a MP3 speaker setup. Hence the necessity to purchase an AC to USB adaptor for those that don't want to use it as PC speakers as well (where USB ports are bountiful), if your MP3 unit charges through USB that is.

The amp does a great job and delivers a great sound. When you turn the sub off, you hear what you would expect to hear, just pure treble. And the nicest part is that you can manually set the bass level with the volume knob on the back of the sub. The sub although small, delivers a great amount of bass. It won't blow away bigger and more expensive subs, but for it's price range, it's well worth it.

My favorite part was learning that the unit can dual task, be a great iPod speaker system AND connect to the pc at the same time. This may also be a double edged sword as you can mix two songs at once, aka while the iPod is playing, the input from the computer is mixed with it. While some may see this as a hindrance, I see it as a bonus. What would have been nice, is the OPTION for the user to decide, mixed or not. And then decide the priority. Although this would most likely result in 1) a more expensive product 2) a bigger unit. Just be sure to NOT play songs from your computer AND your MP3 player at the same time, unless you want to be a DJ.

All in all, for it's price range I feel that this is a great 2.1 speaker system that allows the user to have the ability to use it solely for MP3 or dual use. A great sounding unit with clean bass and manual bass control. You will not be disappointed in buying one.

Summary: These speakers boost the sound of the music and games I play on my desktop, compared to the small bundled PC speakers I already had. Best thing is that boom-boom sound I got with the subwoofer. Has a headphone jack input. An extra was the ability to connect an mp3 player with the included cable and place it on the stowaway cradle. 2 year warranty period.
I did not like the fact that everything is wired together. But it is a small inconvenience. Once the speakers and subwoofer are in place, I don't expect to be moving them around.

Summary: I got these speakers for a great price after rebate. It is otherwise not worth the full price. THey are ok for a desktop. For my purpose it is alright.
