Customer Ratings & Reviews

Though clarity is good the volume is too low. It is not a good buy for fifty watts of power.

I have had these speakers for three weeks. They sounded great until the slave speaker blew. I always make it a rule never to turn the sound past 75% to preserve speakers, and yet it's blown. I will be taking this system back to see if I can get it replaced.

sounds nice, but my left speaker started distorting on the high end after only a week. i use no more than 70% input voltage and 50% output volume. this shouldn't have happened

Sould clarity is awsome, loud bass, for the price this thing is well worth it.(louder and nice than my soudbar I spent $100 more on.)

Great sound! Wanted something to replace my old pc speakers. Awesome sound out of 2 speakers and subwoofer!! I'm impressed! Love it!!!

Work very well, easy set up, and very clear, no buyer's remorse

Wow do these speakers sound like a movie surround sound system. I cannot believe how Awesome these are. Will definitely buy again

These speakers sounds great! If you only have a single input connected. With more than one connected, power by the same source, welcome to the wonderful world of ground loops. My meter clearly shows all of the inputs on these things have tied ground, meaning it's pretty much just a ground loop waiting to happen. Logitech apparently can't be bothered to isolate grounds on a high powered audio amp that's meant to be used with multiple inputs at the same time!

Since I'm separating my studio from my work office, I needed a pair of descent speakers to use in my office. I wasn't looking for something super classy (I already have the JBL studio monitors with the Yamaha subwoofer) but at least something I can jam too while i work from my home office. These speakers were cheap and easy to use. But in retrospect i wouldn't buy them. They start to glitch after a few hours and the sound cuts in and out. It gets very, very annoying. I can't stand it actually. Very, very rarely do I give bad reviews on Bestbuy.com but I have to keep it 100 with you all. This is a waste of money. Don't get me wrong, Logitech makes amazing computer accessories and what not. I'm just not sure their speakers are worth buying.

Good speakers for a good price I highly recommend.

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.

The speakers sound great. Easy hookup. Definitely worth taking into consideration if looking for speakers.

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
