Customer Ratings & Reviews

The volume is a little less than I was expecting at 400 watts systems. The sound is flat. I was not happy with the sound of any of my music through this speaker system. It was not as good as other Logitech computer speaker systems I have purchased before or even a much cheaper and lower powered Philips computer speaker system I still use. Right now I put it on s split output with the Philips system to make the music sound good. The Philips more complete range fills in the missing mid and high tones. Overall was disappointed for the very first time with a Logitech computer speaker set.

Bought this system because I thought my current speaker system died. Apparently the problem was with my PC and a bad sound card. Just got the pc back from Dell after long delays because of COVID19. Tried the new sound system. Followed the directions EXACTLY as provided on the box, even moved plugs. Cannot get rid of the overbearing terrible buzz coming out of the subwoofer. No additional material was packed in the box. Went to the store, 1st time no experienced personnel were available, stopped back in the store yesterday waited 35 minutes to get help that didn't happen so I left the store. Got on the Logitech website, saw that others had the same problem. Logitech recommended returning the item to the store. Not impressed, no resources after the sale. Will be returning tomorrow.

Big speakers in and always the best speakers choosing small speakers that have audio quality and of course Bluetooth capabilities make it useful for smaller devices to use for audio

When you get the speaker make sure to break the sub in or it will blow

I order one and it arrived i got it set up and the left one made a weird nose that obviously it wasnt supposed to. I returned it and got another just for the right one to do it this time:(. I love how they sound besides the little sound messing up. Would recommend, just have them test them in the store.

I got z623 speakers about a year and half ago. I was looking for a set that had a good punch, great sound quality, and something that wouldn't take that much space. These speakers were perfect for me. Let me just say, these speakers easily pack a punch! I've never had the volume past 35% because it was loud by that time. Even at very loud volumes, the sound is still at an extremely good quality, no crackling or other issues. When it comes to the bass, these speakers can handle it. Not even halfway on the bass dial, and my room is shaking. I generally use these speakers for music, but they are just as amazing with movies and games. These speakers prove that I will continue to be a Logitech Customer.

This speaker system has incredible sound. All sound is crystal clear.

Sound system far exceeded my expectations.i would highly recommend

I save this speaker for two weeks on my cart cause of the price it's $109 for me it's too much for 109 so then it go down to $99 I'm sure that's the best price for it thank you B.B I got two of this one for my B rom one for the basement

Doesn't allow you to switch between inputs without disconnecting like it says on the box! Tech support told me it really doesn't have that capability.

the smaller speakers had very little sound quality. I had them at either end of my desk with the base unit on the floor, almost all of the sound was from the floor. For speakers in this price range, I expected more. If you like lots of pounding base, at high volume, you'd like this setup .

Perfectly adequate and suitable for computer speakers.

Super loud and for a great price it just can't be beat

Bought these in Rkfd, Ill , highest wattage for desktop gaming speakers. Yoi can feel the base, but tiny speakers cant handle the base. Base dial, volume dial. No treble dial, i cable to hook to speaker out, they dont have thier own speaker wires for a dedicated sound card ! My old Altec gaming speakers put these too shame !

Sounded great for 2 weeks..after that everything was distorted beyond. Garbage

I thought it was going to have a better sound. It got bass but not button for treble.

Easy to install. recommend using the Bluetooth adapter to reduce wire clutter and more speaker location flexibility.

Don't understand why this speaker system comes with such short wires. Had to order longer wires for my connections.

The sound is so good! I haven't had any sound for some time for my computer so it is heaven that the sound is so good.

No bass from subwoofer , the two tabletop speakers wear good
