Customer Ratings & Reviews

Don’t buy this junk, subwoofer is over powering for the speakers it comes with. The woofer rattles and buzzes for no reason even at 15% volume , terrible sound as well. I returned my Logitech z407s and paid the price difference thinking I would get a better product, but boy was I wrong. This is totally off topic but i personally think the overall design looks out dated , looks like something you would have back in 2009.

POOR quality control on Logitech's part! The left side speaker connector at the sub was loose causing an audible short. I am thankful the defect presented itself immediately upon setup rather than after Best Buy's return window closed. I bought them based of all the positive reviews. These are going back right after Christmas.

RECENTLY BOUGHTED ONE AND RETURNED DUE TO A FAILURE TO 3.5 CONNECTION AFTER THE 14 DAYS I LOSTED MY DEAL AND I WAS REQUESTED AGAIN TO PAY ONE MORE PROTECTION PURCHASE ITEM THE NEW ITEM THE SAME ...AGAIN 3.5 SPEAKER CONNECTION FAILED! I DON'T RECOMMEND THIS ITEM

Just average for the time I had it. Started to shorting out. So I threw it away. Should have saved up and got studio speakers.

I didn't try the speakers for 30 days. When I did the sub woofer gave no sound. My $30 speakers have more bass response that these did. I took them back to Best Buy who said that I waited too long to return them and said my only recourse was with the manufacturer. Logitech hasn't answered a phone call but when I left a voice message I did receive an incident number. Two weeks later that's still been my only response.

If you like being in control of your sound these are the speakers for you!

They stop working after u purchase. I can't do anything with these

Speakers have a very loud high pitch sound as soon as I turn it on. It isn't hooked up to anything, but speakers to the subwoofer. There are hundreds of online users complaining of the same issue dating as back as 4 yrs ago. Looks like Logitech hasn't fixed whatever issue it is. Returning it!!

I got these speakers about 2 years ago for $100 on sale. They are absolutely fantastic - I am actually listening to them right now. The right speaker has a power on/off switch (which is hard to find on other systems), a volume control, and a bass control. I typically have my computer set to 50% volume and will adjust the speakers accordingly. Even at 50% on both systems, my room shakes due to the bass. I typically don't raise it higher than that combination. It hits the highs, mids, and lows very well and I completely understand why these are THX certified.

works good for a while but seems i always burn out the sub, they replaced it for free though

The Logitech z623 sound is amazing, I listen to mostly Trance and Electronica in general, but I can tell you everything sounds fantastic on it, I also own the z2300 which I have hooked up to my Samsung 3D TV and I can tell you that it falls slightly behind it in terms of bass, but just a little, and I would say the satellite speakers sound better than those in the z2300, I certainly do not regret buying it at all. And to the people saying the cables are short, people it's SOOOO easy to go buy one audio extension cable, they are less than $5 in any electronics store, you just need to buy the cable and an extender plug and that's it, cable length is an issue for me with my z2300 because of the way I have it set up with my TV and I just got one extension cables from Bestbuy. Get this today!

The sound is horrible. It has a high pitch tinny noise at all levels. Like the speaker is blown out or manufactured incorrectly. Also the main connector has 2 retention screws but one is missing threads. Quality control is definitely lacking here. Definitely not worth the time and money.

The Logitech Z623 2.1 speaker setup offers a very good experience overall. The headset and audio input right on the speaker is very convenient and the sound quality is very good excellent. If you are considering a Bose setup, save your money and consider this or the Klipsch product at half price and all of the performance. The one drawback is it is always nice to have plug style connectors going into the speakers instead of fixed wire, but Logitech has done a good job with this particular fixed wire. It is very sturdy and gives the impression that it will last over time. If you are putting this is a fixed spot on your desk, there should be no/very little wear and tear. The subwoofer handles music, movies, and gaming very well and can easily be controlled from the right speaker module. It's very easy to tone it down for music and throtlle it up for thunderous bass in gaming and movies.

First off, the satellite speakers are larger that I thought they would be. Heavier and better built than what the image may apply. They actually are very loud and if I turn it more than a third up, it gets a bit too loud since they are computer speakers and not very far from you. The sound stage is very good and you feel the spacious sound imaging. Secondly, the sub woofer is smaller than I thought. But it packs a punch. It actually can go pretty low and does well. It does have a limit though so don't expect it to be a competition sub. However, it really is above par versus its competitors in the same price category. Overall, very good set and if you can grab a set on sale, do it.

Had it for little over a year and I think the quality is already diminishing

When I first opened the box I thought to my self that this bass is pretty big, but since it's a 130 watt sub with two 35 watt speakers. It got to be very nice. It turned out it was the best speakers I have ever bought and the price is really worth it. So if you like good shaking the house bass these are the computer speakers you would probably want to buy. Since its approved buy THX the audio is brilliant. Another nice thing about the speakers is that they have a bass, volume and power button built into the right speaker, so for example if your in your house if the bass is to high and the neighbors don't yell at you. you could turn the bass down.

There is really no need to break the bank for an expensive home theater system because the Logitech Z623 will give you the same experience, but at a more affordable price. I will keep my review as brief as possible. When it comes to HTS or, in this case, speakers and subwoofers, I tend to look for 2 main attributes: bass and appearance. The bass level for this particular system is quite spectacular! I'm talking mega bass that bangs and booms, all while maintaining clear, crisp audio. And the hookup process is effortless. I connected my 73" flat screen television and PS3 to the subwoofer and boy was I blown away! I don't know how I've gone this long without audio replacement. As of this moment, I'm prepared to buy the same Logitech system again within this month! 20 stars if it were possible!

Powerful but sounds quality is bad when you up the volume to high level.

They do the job. Not as loud as I would've liked but eh you get what you pay for.

I MADE A MISTAKE BUYING THIS PRODUCT ALL I GET IS HUMMING FROM IT. CALLING GEEK SQUAD FOR ASSISTANCE DIDN'T HELP THEY NEVER ANSWER THE PHONE. MY TIME HAS RAN OUT TO BRING IT BACK I'm handicapped I am very sad and disappointed yhey may be busted and i have them hooked up the proper way.
