Logitech Z623 Vs Z625

At first glance, Z623 and Z625 appear to be identical. There are, however, some discernible differences if you look closely. First, despite the fact that the design and color are nearly identical, the Logitech Z625 is slightly smaller than the Z623.

As a result, the Z625 is slightly lighter than the Z623. Another difference between the two models is that the Z625 has a matte finish, whereas the Z623 has a glossy finish.

Leaving all of that aside, let’s take a look at the more significant differences in terms of features and more:


The main distinction between the two THX Certified Logitech Speaker models is the Optical Input. The Logitech Z623 has analogue inputs. The Z625 model, on the other hand, has an optical input. In terms of performance, the Z625 has a slight advantage.

Optical ports opens up a plethora of possibilities, the most important of which is that this additional connectivity feature may force you to replace your soundbars. The optical input is frequently overlooked, but it is a gift that allows you to connect seamlessly!

You know what? Optical Connectivity is the super one due to the isolation of audio.

What will this do? It helps increase the precision of the system. Ohh wow! Isn’t it amazing?


Is warranty something that really matters?

Obviously YES!!

But majority of people are unconcerned about warranties and this may influence some people’s decisions.

The Logitech Z625 speaker comes with a two-year limited hardware warranty.

The Z623 model, on the other hand, comes with only a one-year limited hardware warranty.


Both speakers provide a degree of sound quality that is unexpectedly good for their price range. However, when connection and additional power are considered, the Logitech Z625 has a small advantage over the Logitech Z623. If you don’t mind the absence of Bluetooth and wireless connectivity, either is an excellent buy.


The Logitech Z623 includes:

  1. There are two analogue inputs (3.5mm aux)
  2. A stereo analogue RCA input (no outputs, though)
  3. A headphone jack (3.5mm)

The Logitech Z625 has all of the above plus a digital optical input (S/PDIF), giving it a minor advantage over its smaller sibling.

One minor stipulation: Neither of these systems have Airplay or Bluetooth Connectivity. This might be a deal-breaker in an age where many of us rely on our phones and gadgets for most of our music consumption. Many of which no longer have analogue audio outputs.

There is no USB connectivity or remote control, either.


The Logitech Z623 has two wired input options: 3.5 mm and RCA.

The Logitech Z625 on the other hand, includes three input methods: 3.5 mm, RCA, and optical.


Finally, the distinctions between the Logitech Z623 and Z625 are as follows:

Design (The Logitech Z625 wins by a narrow margin since it is not entirely made of plastic).

Dimensions and weight (The Logitech Z623 is more compact).

Connectivity: (Hands down winner: Logitech Z625 owing to the presence of digital optical input (S/PDIF) and the choices that open up as a consequence).

Sound (Winner: the Logitech Z625, which offers more power).

Cost: (Winner Logitech Z623: It offers more value for a minimum difference due to increased connectivity)

Logitech Z623 vs Z625 POINT TO PONDER:

Have you ever noticed that Logitech has primarily added the optical input feature to the Z625 speaker system. Still, we can’t deny that Logitech Z623 is one of the best speakers, and a little tweaking makes it even better!

Adding an optical input or optical audio port opens up a plethora of new possibilities, and deciding between these two models is a difficult decision.


The battle of Logitech z623 vs z625 THX certified speaker system ends with the fact that the Logitech Z625 speakers clearly have a slight advantage over the Logitech Z623 speakers. You should definitely prioritize your needs. What you have to do is to consider what you want and depending on that choose the devices that will be required to connect the speakers.

If you are not on a tight budget, the Logitech Z625 model speakers is an option. If spending a few extra dollars bothers you, and you really don’t need any additional input (or could work just fine without it), you can go with the Logitech Z623 speaker system.


In order to give you a straightforward answer to this question, I would suggest you to go for the Logitech Z625 model speakers among these two speakers as this will provide you with high volume as compared to the Logitech z623 speaker or other speakers.
