Connectivity
Good connectivity comes from three things. First, it comes from how the device connects to the primary source. Most gaming headphones connect via a receiver, cables, or Bluetooth connection. Wireless connectivity is just as popular as wired connections.
Second, connectivity refers to the performance of these sound devices when connected to the source. Depending on the model technology and caliber of the connection, you’ll get upgrades and enhancements that old models lack, which produce better sound quality.
Lastly, relevant model software vastly improves the features and functions of the device. The majority of improvements and enhancements come from software renovation as well. Headphones are more than just the physical look that sports a high-class look.
PC cable
Both the G633 and 635 make use of wired connections for PC use. There is an extended cable that comes from the gaming headphones and connects to the socket. Usually, the socket is a USB port type. Both cable lengths of the models are the same, with a PC cable length of 2.8 meters.
Mobile cable
The two gaming headphone models also connect to mobile phones. The mobile sound mode is supported with the 3.5mm headphone jack. The only difference is that the cable length of the 3.5mm is only 1.5 meters, which is about half the length of the PC cable.
Logitech software
For PC mode, the G633 and the G635 work on Windows and MAC OS. While for mobile phone mode, the headphones work on mobile models with a headphone jack. The connection to the PC is supported with the Logitech G HUB software.
Console compatibility
The models also connect to gaming consoles, given there are proper USB 2.0 ports or headphone jacks. You can enjoy PlayStation 5, Xbox 360, or Nintendo Switch games with the G633 and the G635.
Sound quality
Sound quality is the core product of any sound device. If you want to invest in more high-end headphones, the sound quality matters the most. Good models should be able to give you the best sounds that you want. We’re all looking for the crisp, clear, and dynamic sound ranges those headphones should provide.
Audio frequency response range
The G633 and G635 have a frequency range of 20 Hz to 20 kHz. While this frequency is the standard range for good headphones to have normal bass, mid, and trebles, both models have above-average audio sensitivity. The G633 and G635 sport 93 DB SPL/mW, giving more precise sound while consuming less power.
Surround sound capability
Both models have the Headphone:X 2.0 Surround Sound, which powers precise sound. The sound abilities and quality of the G633 and G635 power 3D soundscape, making you “hear everything” when in-game. If you are playing games, hearing dynamic sounds can change how you can win or lose the game.
Noise cancellation
There is one downfall to the G633 and G635 models of Logitech gaming headphones. These models don’t have noise cancellation settings and barely isolate sound from outside. It’s best to play in quiet environments to get optimal sound quality.
Microphone
Another aspect of headphones that is crucial to users is the quality of the microphone. For live streaming of sound, a clear microphone works best to elevate communication.
Microphone frequency response range
The G633 and the G635 have boom microphones that pick up unidirectional sounds. The frequency range of the microphone ranges from 100 Hz to 10 kHz. The microphone slides in and out of the compartment of the headphone set.
Microphone controls and customization
Microphones of the G633 and the G635 come with various settings. Volume levels are highly adjustable; there are adjustment levels for sidetone or the volume you can hear your voice.
Size
In both models, the microphone differs in microphone size, with the G635 better than G633. With a 6 mm microphone, the G635 is bigger than the G633’s 4 mm microphone.
Comfort
Everybody wants a comfortable pair of headphones for long-time games and use. The last thing users want is to have painful ear canals or outer ears from supporting the headphones.
Material
Luckily, the G633 and the G635 are comfortable and delightful to the ears. The build of the two models includes a woven mesh material that doesn’t sacrifice the device’s audio quality.
Diameter size
The bigger headphones’ diameter supports the performance of the G633 and the G635. Large circumaural headphones fit around the ears without the numbing presence of pressure on soft tissues of the ears. The ear cups are detachable, so you can easily wash and dry the material of the headphones.
Design
There’s easy access to the microphone as the design of the G633, and the G635 includes flip-up mic storage. The models don’t only have a comfortable design but also indicative alerts. LED indicators signify some function of the microphone, such as mute mode or in-use mode.
Weight
The weight factor of the models is easily manageable. The G633 and the G635 are 12.06 oz. The weight is lighter than many headphone models but doesn’t sacrifice the features and design of the product.
Controls
The customizable software of the G633 and the G635 are present with Logitech’s high-end software. The Logitech G Hub can program the settings and some button controls of the gaming headphones.
The Logitech G Hub software supports various profiles to fit each user. These devices don’t need to stick to one setting, but they can provide multiple control settings and audio profiles unique for every user.
Price
The G635 costs $139.99 for retail and $99.99 for sale price. The G633 costs the same price.
Conclusion – Logitech G633 vs G635
The G635 is the newer version of the G633. There is no major change to the G633 compared to the G635. Consider the G635 as a revamp of the older model, meaning the minor tweaks and changes translate to a better audio experience for the user.
These models work best as neutral sound profiles to accommodate a balanced mix of bass, mids, and treble. Another strength of both models is the ability to customize via Logitech’s software. With the Logitech G hub support of the G633 and the G635, you can change how you want to experience more convenient headphone usage.
