About the Logitech Z623: An Overview

Additionally, the right speaker also features all the main controls in front of it which include, power on and off, volume rocker, and bass level.

Both of the left and right satellites have a front-firing driver which pushes the bass-forward. This means you have two speakers in front of you that are throwing all the bass you need towards you while also giving you all the controls you need.

The right speaker also includes such as a 3.5 mm input, an AUX port, and a headphone jack for your convenience.

Lastly, you have the subwoofer; the hefty size of the speaker contains a fairly small woofer driver. This is questionable by some but, that driver alone packs a lot of power when delivering audio.

Moreover, the inputs are also on the right speakers unlike typical speakers in the market. If you look at the back of the subwoofer, you will find the RCA input which connects directly to your PC or music/audio system.

Now, to come to the design part, these speakers have a rubber grip on the bottom of each unit to keep them from moving when playing music at a high volume and bass. Since these speakers can get loud, the rubber grips are a good addition.

About the Logitech Z625: An Overview

The Logitech Z625, much similar to the previously mentioned Logitech Z623, is a small multimedia speaker system with a subwoofer, that is a good starter for gaming setup enthusiasts who are looking for a budget speaker to complete their setup.


The main attraction of the Z625 is its optical input feature. The optical input is a connection that is super fast and is commonly seen in many soundbars. This is greatly useful for the connectivity of the speakers with the audio device.

A TV that has multiple HDMI inputs will greatly benefit from this feature since the routing is seamless and fast.

Many gaming consoles and TVs now comprise optical ports that connect to soundbars. But, with Logitech closing in the gap, the Z625 is now on par with many soundbars. The optical input helps users conveniently change inputs of the TV and the audio will be routed automatically to the speakers without the hassle of you changing it manually.


The subwoofer is, as usual, provides ground thumping bass and does not compromise in performance. You can feel the bass along with the music or while gaming and they are smooth and cleaner.

The mid and high range frequencies in the Z625s are not something to ignore either. It is crisp, clear, and most interestingly, the quality does not get distorted even at high volumes.

Additionally, there is also the convenience of the speakers turning on with the audio device together as one. The optical connectivity is good and also not the only feature that puts the Z625 in the speaker game with the top dogs.

It features a crystal clear 2.1 surround sound experience that makes you feel like you are listening to a 7.1 surround sound system.

Pretty crazy right? It is all because of the speaker driver’s efficiency in maintaining the mid-range quality of the audio and simulating the surround sound effect with great ease.

This is ideal for gamers and especially while watching movies. With only two drivers, the Logitech Z625 is easily one of the best budget gaming and multimedia speakers in the market.

Points for Praise:

  • The subwoofer is powerful and produces great bass, enough to shake the windows.
  • The volume is fairly loud and clear.
  • There are no distortions at high volumes.
  • You can connect multiple devices at once and it stays connected.
  • Features an optical input ideal for a high-end TV, monitor, and gaming consoles.
  • THX-certified speaker system.

Points for Improvement:

  • The high frequencies might not be clear enough.
  • No remote control included.
  • Could have featured Bluetooth connectivity.

Excellent features

To put it bluntly, these speakers are simply appalling when it comes to quality and performance. Especially for a $150 speaker, these are definitely mind-blowing and deliver amazing results. You cannot go wrong when buying this product, they will go perfectly with your gaming setup or as a workstation speaker.

The optical input is the main attractive feature that opens up a lot of different possibilities when it comes to connectivity. You can even replace your soundbars with these because of how good the Z625 sound and of course, the optical input is a blessing. The ability to connect seamlessly and that too in such a small device is simply astonishing.

Lastly, with all multiple inputs, it is expected to see some latency but the Z625 can stay connected with multiple devices at the same time without affecting the audio quality. Also, these look great and the surprisingly good  2.1 surround sound only strengthens the case of you wanting the Logitech Z625 speakers.

Product Differentiators: Logitech Z623 vs Z625

Both of these 2.1 speaker sets for a desktop sound system,  Logitech Z623 vs Z625, sound fantastic and will fill a small area if your sound cards output is set up properly for the area and speaker arrangement or placements.

Design and features

At first glance, you will not see any significant difference between the Z625 and the Z623 except for a matte finish. Without that slight shift in the glossy finish of the Z625 over the Z623 but other than that, they both look and are designed the same with all the same controls, shape, and style. The Z623 is a little glossier and people refer the Z625 as the successor to the Z623s. This speaker has all that is in its predecessor and more.

The one difference where the Z625 supersedes the Z623 is the optical input. The Z625 features an optical input that is highly beneficial by most TVs and gaming consoles. This feature is also what lets the Z625 compete with soundbars which are increasingly popular these days.


Sure enough, these will not be as powerful as your home theatre setups that deliver loud booms and clear vocals. But, the Logitech Z623 and the Z625 are a beast when it comes to tabletop speakers or when used in close proximity.

In other words, you can call them near field speakers as well. Aside from performance, they look ecstatic. These will go great on your desk, as a room speaker, or in gaming setups.

Additionally, in terms of performance, the difference is almost unnoticeable but, if you are a true audiophile or an audio engineer perhaps, you will be able to tell the difference in quality. The Z625 has more full and clearer audio than the Z623. The highs are clearer which is ideal for vocals and dialogues and that is the department where most speakers fail to live up to.

Most of the features are the same between the Z623 and the Z625 and that is mainly because the Logitech Z625 is a small upgrade from its predecessor only to get ahead in the speaker competition. These speakers were built with consumers’ convenience in mind, the near hand controls are a great feature that most speakers lack.
