The Logitech Z623 and Logitech Z625 are some of the best-selling 2.1 speaker systems on the market. Not only do they deliver high-quality audio, but they’re also one of the few speaker systems on their price range that boast THX certification. The Logitech Z623 and Z625 are essentially the same, save for the optical input added to the latter. To help you decide whether these speakers meet your requirements, we deep dive into their specs and features below.

The Logitech Z623 and Z625 have the same design, but the Z625 comes with an optical input
While they are on the affordable end of the spectrum, the Logitech Z623 and Z625 both have a plastic finish that doesn’t look and feel cheap. The subwoofer and two satellite speakers are well-built and don’t break easily. Their controls are housed on the right speaker, which includes the power button and volume and bass knobs on the front. On their side are the headphone jack and a 3.55mm AUX input.
Meanwhile, their subwoofer sports a classic frame with sharp edges and a metal grille at the center. You can’t tell the Logitech Z623 and Z625 apart, unless you take a look at their subwoofer’s inputs located at the rear. The Z623 only has analog inputs while the Z625 comes with an additional optical audio port.
The Logitech Z623 and Z625 are THX certified and deliver booming bass
As we have mentioned, the Logitech Z623 and Z625 are among the few THX (Tomlinson Holman’s Experiment) Certified speaker systems at their price point. This makes for an immersive gaming and movie experience as they deliver accurate tonal balance. They produce powerful bass and their mids are clear and undistorted. You can also adjust the bass to suit your preference using the dial on the right satellite speaker. As for the highs, they are just right and don’t cause listening fatigue even if you listen for an extended period.
Of course, more expensive subwoofers can deliver slightly better, cleaner bass. The Logitech Z623 and Z625 are not designed to please audiophiles either. However, for their price, these Logitech speakers definitely exceed expectations.
The Logitech Z623 and Z625 work with a wide range of devices, but they don’t support Bluetooth connectivity
You can connect an array of devices to the Logitech Z623 and Z625, such as computers, TVs, media players, and gaming consoles. The Z623 only features a 3.5 headphone jack and RCA inputs while the Z625 comes with an optical audio port for processing higher-quality audio. You can connect three devices simultaneously to the Z625 so you won’t have to disconnect every time you want to change between your devices.
Their cables are long enough for most desktop set-ups, but it’s good to check whether your arrangement at home will require purchasing a longer cable. Here are the measurements of their cable to help you decide:
- Optical cable (Logitech Z625): 6’4″ / 1.9 m
- Power cable: 7″ / 2.13 m
- Satellite speaker cable: 7’4″ / 2.4 m
- 3.5 mm cable: 5′ / 1.5 m
Perhaps something Logitech could have included to the Z623 and Z625 is Bluetooth connectivity for a faster, more convenient connection. With that said, they’re still easy to set-up and connect to your preferred device.
Both are solid choices, but the Logitech Z625 can support more audio formats than the Z623
Boasting THX Certification, powerful, undistorted bass, and clean mids and highs, the Logitech Z623 and Logitech Z625 offer excellent value for your money. They’re among the best 2.1 speaker systems you can get that won’t break your bank. Whether you’re a heavy gamer or a film buff, the Logitech Z623 and Z625 won’t disappoint. Between the two, however, we recommend going for the Logitech Z625 as its optical audio input can support higher-quality audio formats than what analog inputs can.
Absolutely. The Logitech Z623 and Z625, both THX certified, offer excellent value for your money and remain among the best speaker systems in their price range.
Just as Logitech mice and keyboards are among the best in the industry, the Logitech speakers such as the Z623 and Z625 are also reliable and deliver high-quality audio. Logitech recently acquired Ultimate Ears, thus you can be assured that you’ll get the same, if not better, sound quality.
No, they don’t support Bluetooth connectivity. However, there are other Logitech speakers that are equipped with Bluetooth, such as the Logitech Z337 Bold.
