4 out of 5 eggsGreat speaker set, very short cables

Pros: This is a very solid set of speakers. Unless you are an audiophile, these work great for desktop music and gaming. They won't be as awesome as a solid surround sound system, but good surround sound is surprisingly tricky to set up and really only marginally better whereas these are plug-and-play.

Cons: The cables are WAY too short. The cables are only about 6 feet long. You should keep speaker equipment, no matter how well-shielded, far away from other computer equipment. For me, that means the subwoofer sits on the other side of a 5.5 foot desk. Then the distance to the on-board audio on the motherboard is another few inches and the distance to the subwoofer is a couple more. In other words, I'm currently straining an audio cable to just barely make this work and I'll be buying a longer cable on Newegg shortly. The other cable to the right speaker is also not perfectly relaxed due to the size of my desk...and my desk is pretty small compared to a lot of desks out there! Even if I put the subwoofer on the other side of the desk and next to the computer, the left speaker cable would be too short and it seems flimsy compared to the right cable. Logitech needs to add 2-3 feet of cable to ALL of the cables in this speaker set. Cabling is one area that shouldn't ever be skimped on.

Other Thoughts: I own the Logitech Z5500, the Logitech X140, and now the Z623 speaker sets. The Z5500 is the best 5.1 computer speaker set I've used in terms of audio quality. The X140 has laughable audio. The Z623 is similar to the Z5500 in terms of audio quality but doesn't produce as rich a sound. The materials of the Z623 feel like they are of slightly lower quality than the Z5500, which seems to be in line with the general consensus of this model. RMS wattage, frequency response, and quality materials in construction all seem to matter when it comes to reproducing audio.

5 out of 5 eggsDesktop speakers

Pros: Great speakers. If you like some bass sounding music or some of that explosive sound during an action movie, you must look into these speakers. Even though they are only 2.1, they still make a living room sound like there is surround sound. Great that you can have multiple aux jacks, one on the speaker that goes on your desk, and another extra on the side of the sub.

Cons: None, just great build quality and sound is amazing.

5 out of 5 eggsGreat Speakers

Pros: Great loud sound
Great bass, like shake your house and anger off your neighbors bass
Good highs, they could be better and clearer at higher volumes
It's a room filling 2.1 system

Cons: White noise at high volumes when no sound is playing
cords could be longer, but they fit on my computer desk
Volume and bass at 100% causes the speakers and sub-woofer to give off a burning smell and might smoke a little bit, but I will say that you don't need them that loud at 50% these speakers will fill a house with sound.

Other Thoughts: I love this speaker system, although I will state I have not owned another. I've had my speaker system for over 2 years, almost 3 in fact. I don't even want to look for another speaker system, plays music and game sounds very well. Has pretty good room filling presence. These are 100% worth the price tag, and they even go on sale a lot. Completely happy. I know a 5 star review probably isn't warranted with all the cons I listed, but those cons don't matter to me.

3 out of 5 eggsGood sound till it breaks.

Pros: Worked great, sounded great until my left speaker stopped working.

Cons: Left speaker stopped working due to the female plugin being loose. Happened less than 6 months after purchase, very disappointing this was the only item I didn't buy an extended warranty for, I guess I know now.

1 out of 5 eggsZ623

Pros: Decent Bass
Bass Control, Volume Control, and Power Button on Satellites instead of using Control Pod

Cons: -Fuzzy/Hissing sound when tuned the volume at 50% or higher
-Volume Speaker sounds awfully too low even at volume 40% or more.
-Requires too much wattage to raise the bass!
-Subwoofer is enormously big to some users who live in small dorm room for college
-Audio Sound Quality sounds as worse as Z523 & Z323 Speaker System
-Too prohibitive with terrible sound quality even without Dedicated Sound Card

Other Thoughts: Don't buy Z623, Z523, or Z323 Speaker System. All three speaker systems that Logitech want to sell are useless! Go with Logitech Z313 2.1 Speaker System. I've bought Z313 speaker system back in 2009 and it still sounds much much cleaner and louder than Z623,m Z523, and Z323 Speakers!

No Sound Card is needed unless you purchased Corsair SP2500 Speaker system and you'll also need Dedicated Sound Card to convert Digital to Analog signal without compromising Audio Quality, especially for those guys who are working on Audiophile work. Overall, I highly recommend Z313 with reasonable pricing, performance, and reliability!

4 out of 5 eggsgreat bass

Pros: sound great. always had 5.1 but got sick of all the wires, and these things are, imho, just as good and the bass is way better then anything i have had to date. desktop speakers are small but really heavy for the size and don't slide around when making adjustments

Cons: headphone jack is impossible. stupid tight and you REALLY have to push to get the jack fully seated. every time i pull the jack out i think its going to rip off. crossover can be...temperamental, occasional odd noises, or a speaker will cut out for a bit. power cycling seams to fix any of the issues.

Other Thoughts: the headphone jack cost it a star, the sound is good enough to make up for the occasional crossover burp.

5 out of 5 eggsAmazing Speakers

Pros: Awesome bass and clear highs at pretty crazy loud levels. The bass is clear and can be felt across the room, and the highs seem to carry throughout and into other rooms. These are the best 2.1 speakers i have owned or even heard. Buy them!

Cons: I can't think of any.

5 out of 5 eggsBooming and Clear

Pros: Great sound separation, and room filling sound. At less than 20% volume, it easily fills my home office, with room to spare. If I push it to 50%, it nearly fills the house. I don't have a need to ever go that high, in practical scenarios. Music is crisp, dialogue is clear, and it has a lot of punch in a small package.

Cons: There is some distortion and cut-out if I push the speakers to around 75%. But, realistically, I am never going to push them that far. Considering that they meet my needs, and can deliver the volume levels that I would want, definitely am not going to ding it for an egg at this point.

Other Thoughts: I don't claim to be an audiophile, by any means, but I do enjoy a wide variety of music, from rock, to metal, to classical, to old school rap - a sampling across my library has been more than satisfactory through this setup. These can really thump, but I do not have the issue that others claim, where turning the bass down has little to no effect. I can drop the bass to near-nil, and get a pretty good sound, still. The mids are a little muddy, but for the price of the speakers, they definitely exceed my expectations.

5 out of 5 eggsImpressive

Pros: Deep, rich sound. Hearing lows & highs I didn't know existed in favorite music. Crisp sound. Room shaking bass - but easily adjustable, loud - if you want it. Nicely styled, quality feel. Long enough cables.

Cons: None - wish I had bought these sooner.

Other Thoughts: I had the z523 which served me well for a couple of years and moved them to another computer. Having a good experience with the z523s & reading good reviews of the z623, I took the plunge. But I was not expecting such a huge difference in the quality of the sound. My music is so much richer & games are more immersive. Definitely recommended.
