Introduction and Specifications

Logitech has been releasing gaming headphones with a steady regularity of late, and this summer we have another new model to examine in the G433 Gaming Headset, which has just been released (along with the G233). This wired, 7.1-channel capable headset is quite different visually from previous Logitech models as is finished with an interesting “lightweight, hydrophobic fabric shell” and offered in various colors (our review pair is a bright red). But the G433’s have function to go along with the style, as Logitech has focused on both digital and analog sound quality with this third model to incorporate the Logitech’s Pro-G drivers. How do they sound? We’ll find out!

One of the main reasons to consider a gaming headset like this in the first place is the ability to take advantage of multi-channel surround sound from your PC, and with the G433’s (as with the previously reviewed G533) this is accomplished via DTS Headphone:X, a technology which in my experience is capable of producing a convincing sound field that is very close to that of multiple surround drivers. All of this is being created via the same pair of left/right drivers that handle music, and here Logitech is able to boast of some very impressive engineering that produced the Pro-G driver introduced two years ago. An included DAC/headphone amp interfaces with your PC via USB to drive the surround experience, and without this you still have a standard stereo headset that can connect to anything with a 3.5 mm jack.

The G433 is available in four colors, of which we have the red on hand today

If you have not read up on Logitech’s exclusive Pro-G driver, you will find in their description far more similarities to an audiophile headphone company than what we typically associate with a computer peripheral maker. Logitech explains the thinking behind the technology:

“The intent of the Pro-G driver design innovation is to minimize distortion that commonly occurs in headphone drivers. When producing lower frequencies (<1kHz), most speaker diaphragms operate as a solid mass, like a piston in an engine, without bending. When producing many different frequencies at the same time, traditional driver designs can experience distortion caused by different parts of the diaphragm bending when other parts are not. This distortion caused by rapid transition in the speaker material can be tuned and minimized by combining a more flexible material with a specially designed acoustic enclosure. We designed the hybrid-mesh material for the Pro-G driver, along with a unique speaker housing design, to allow for a more smooth transition of movement resulting in a more accurate and less distorted output. This design also yields a more efficient speaker due to less overall output loss due to distortion. The result is an extremely accurate and clear sounding audio experience putting the gamer closer to the original audio of the source material.”

Logitech’s claims about the Pro-G have, in my experience with the previous models featuring these drivers (G633/G933 Artemis Spectrum and G533 Wireless), have been spot on, and I have found them to produce a clarity and detail that rivals ‘audiophile’ stereo headphones.

"The Logitech G533 Wireless Gaming Headset features professional grade wireless technology, patent pending Pro-G audio drivers and DTS Headphone:X 7.1 surround sound, for advanced audio performance and wireless convenience. The Logitech G533 Wireless Gaming Headset also features a long battery life and high performance design, for comfort over long gameplay sessions."

The Pro-G drivers were previously found in the flagship Artemis Spectrum gaming headsets, which I was highly impressed by when I reviewed them a year ago. The new G533 model incorporates much of the same functionality as the wireless G933 headset, with advanced driver technology and DTS Headphone:X 7.1-channel surround effects.

As to the wireless performance, Logitech states that their system is low-latency, completely lossless, and resistant to interference:

"Featuring advanced lossless digital audio transmission, the Logitech G533 delivers wireless convenience and incredible high fidelity sound at a range of up to 15 meters’. The headset maintains a strong connection, even in noisy Electro-Magnetic Interference (EMI) settings and when there are dozens of wireless signals in proximity."
