(Impression review) Logitech Z333 2.1 speakers


Welcome to the first impression review on TFO of the Logitech Z333 2.1 speakers system. Since I don't have much time to spend with the set, I will only do a quick impression review on what I thought is good or not so good about the Z333.

I got a chance to 'play' with the set since one of my customer asked for a decent speakers to come with his custom built PC. With limited budget, Z333 seems is a decent PC speakers that cost 109 SGD (80 USD) at the time of this article and it's readily available in Singapore's Simlim or other electronic stores such as Challenger. Other option such as those from Creative were considered as well, but none of that fit the budget that we had.

I will be using images available on the Internet instead of my own since there was not enough time to fully setup and capture photos of the speakers.


Packaging & Specs

The speakers come in a box that measures 22cm x 35cm x 24cm (HxWxD). The set are tightly packed inside the box and they are only wrapped with a thin layer of plastic and cardboard. As such, be gentle when handling the box since any impact may damage the speakers inside.

Inside the box, you will find 2 satellite speakers and one sub-woofer as expected. However, what was unexpected is that all the necessary cables are hard wired into the satellites and subwoofer itself. Besides that, you will find some plug adapters for your main wall plug.

Power and volume control on wired control pod; bass control on back of subwoofer



The Z333 sports a rectangular look that is plain simple and easy on the eyes. Even though it can look boring at times, I truly appreciate this design more than something that's flashy and plasticky.


The setup process is pretty simple:

  1. Position your sub-woofer so that it's speaker outlet as well as the air vent are not blocked by anything.
  2. Connect 2 satellites to the sub. Place 2 satellites as far apart as possible on your table, pointing toward your head.
  3. Position the control pod in a easy to reach place.
  4. Connect power cable and signal cable.

However, since the control pod, the power cable and the input cable are hard wired into the sub, sometimes it can be awkward and difficult to route the cables to different places. I guess Logitech chose to hard wired these important cables to reduce manufacturing cost.

The control pod itself houses the main on/off switch of the speaker at the side. The volume knob is buttery smooth and I hope the knob itself will last and doesn't become insensitive after years of usage.

In term of volume, the set can get very loud. However, the sound does break up and distort once volume reaches high level. As such, I would recommend this speakers for every day usage and perhaps movie watching in a small room only.

The Z333 come with 2 set of inputs, 3.5mm standard audio jack and RCA jack. Both of these inputs work simultaneously, in the sense that if you input 2 audio signals to the speakers at the same time, the speakers will combine and output both.


My first impression with the set was pretty good. To assess the the sound quality of the speakers, my list of music is as follow:

  • The Scientist by Coldplay cover by Tyler Ward, Kina Grannis and Lindsey Stirling.

This cover include a good mix of low frequency bass (kicks in at 0:13 and 0:53), unique vocal of both male and female singers as well as high frequency of Lindsey's violin.

  • Can You Feel The Love Tonight, The Lion King OST by Tyler Ward

This cover can give a quick test of how the 'more important' bass is handled by the speakers, both in term of quantity and quality.

  • China Traveler by Ewen Carruthers (flac) to assess vocal and instruments.
  • Streets of London by David Roth (flac) to assess the overall sound signature and presentation of the set.

The following impression is made in comparison with my current Hifiman HE-560 planar magnetic headphones, powered by an Asus Xonar STX II sound card.

Vocal and mid range are decent while bass are present. In other word, frequency response from bass to midrange/vocal are quite flat and easy on the ears.

However, high frequency is quite muted. This is apparent in The Scientist in which Lindsey's violin sounded too smooth. In other test tracks, instrument doesn't sound that distinctive as well.

As with small sub-woofer, the lower frequency of bass are not present. By doing a quick frequency response sweep, the speakers can cover from ~65Hz - 15kHz. This confirms the fact that low bass below 65Hz cannot be heard during testing.



  • Decent sound quality for the price.
  • Simple and elegant design.
  • Easy to setup and easy to use.


  • Hard wired cables from the sub and the satellites.
  • Muted treble.

The Z333 is a decent set of speakers for those who are looking for one with a tight budget. If you are looking for better sound quality, I'm afraid that you will have to spend more, though there are a lot more options at higher price bracket.
