First off, let me say that, I am a very very picky person when it comes to sound quality and music. I want it to sound a certain way! I like everything to be well-balanced, but I also like a lot of bass! These are exactly what I always look for in sound quality. The speakers have it! I got my first set of logitech speakers in 2004, and have been buying them ever since. These ones are getting harder to find. The first time I bought them, was for a computer back in 2004, then I got them with my second computer when it was built a few years ago, and just decided to get one for the basement for when I do workouts! I can’t tell you how wonderful these speakers are! Let’s just say, you don’t want to turn the subwoofer up too much, it will rattle your windows! They are that good! I have pictures on my wall, and they all rattle if I put the subwoofer up too high. They are amazing in the basement and doing workouts. I hooked them up and they were perfectly! I’m so happy to have a second pair now. I have bought other speakers, including some other Logitech speakers, but they weren’t quite as good as these. I’m so glad I found some more. I almost thought about getting an extra pair, just in case down the road I need them. They are that good you just want to find more of them. These things are amazing, the sound is well balanced, the base is astronomically. Amazing, they are just really awesome! The price wasn’t bad either. I had a friend told me when he built my computer, you’re gonna be hard-pressed to find a set for 100 bucks. Well, I finally did. Glad I got these. The shipping was great, Speakers were packed nicely, no damages or anything. I’m impressed! All I can say is get these, you won’t be sorry! By the way, these are very easy to set up, I am a blind person, and had no problems.

First, I rarely buy any used or renewed item because I don't want to deal with any possible hazzle. I decided to give this one a try because I trust amazon's return policy.

I'm very surprised to receive a brand new looking unit in original packaging without any visible defect. It looks almost like an open box return. All the cables are included too. (Your mileage may very, other reviewers can attest.)

The speaker is definetely a bang for the buck with a renewed product pricing. The bass provided with and without the sub is night and day. I never realized how much low is missing until I put this speaker up. It lefted my little bluetooth speaker in DUST! The speakers deliver ample amount of bass with bass tuning knob sitting at default mid position. I connected this set with optical link which is the reason I specifically chose z625 for. This eliminates the RF interference from desktop. If I want to go deeper into the rabbit hole, I can always get an external DAC later. So far, everything has been performing perfectly and the only concern is possible complain from neighbour for being too noisy.

Great value, sound is "eh", not bad. Bass is overpowering in a boxy, boomy kind of way, and the satellites are very mid-rangy. Klipsch Pro-media 2.1's on my other system sound much nicer, but hey, this is a great deal and it has optical in, which is great!! Get the re-furbished, they looked brand new when I opened the box!

5.0 out of 5 stars HUGE SOUND / GREAT BASS / AWESOME VALUE

These are loud, REAL LOUD.. I bought them because I wanted a powerful sound system. This hit the spot, a little tweaking the sound with my onboard sound system eq, and I was off to the races.

I really like how you can control the bass separately with a knob next to the the volume, there are times when the bass was too strong. I paid $140 for these but I would have paid more. If you can find these around $150 and looking for value, jump on it.

My box came with virtually no damage, unlike others have reported. So, I was thinking I was lucky and was going to get a really nice set of these Z623 speakers. Upon UN-plasticing the speakers I became even more hopeful because they looked immaculate, just like new.

The problem was with the subwoofer. It makes no sound at all. I've tried various points on the bass knob, various volumes, I've disconnected and reconnected the speakers and their inputs in every order I could think. I've tried both 3.5mm inputs, as well as the RCA inputs. I've tried my PC (which was where the speakers were intended to be placed), I've tried a tablet, even tried a frequency generator. But the bass input seems to only go to the stereo speakers, the sub never makes a sound. 60Hz or lower is something you'd expect to make the subwoofer at least try and emulate the sound. It's super disappointing, I've owned Logitech stuff for many years. It's generally good stuff, I'm even typing this on a G910 keyboard. But it looks like "Refurbished" doesn't actually mean "fully functional" like it's supposed to.

I had the Z313 set from Logitech and I absolutely do not recommend those. Mine lasted a year and the amp or sub blew.

These though are sick! I also love that I got them about $100 off full price through a seller called "BuySPRY". The only reason the item was on sale was because the box was opened. BuySPRY duct taped the edges of the item box to ensure nothing fell out and I appreciate the care.

Hopefully this set lasts longer and the only reason I would get a different system is for surround sound but I didn't want to spend a minimum of about $300. I thought I could add speakers to this set and you can not.
