Logitech G403 vs G703 Best Gaming Mouse 2019

Logitech is a staple name when it comes to providing a performing mouse that caters to gamers, office employees, designers, developers, and casual users. They also design different kinds of mouse that appeal to their varying market. And to date, some of their best-selling mouse both come from the G Series, particularly the G403 and the G703.

We’ll be comparing these two gaming mice through specs, performance, features, and user-friendliness. Because the G703 is a wireless model and the G403 both has a wired and wireless variant, we’ll have wireless models evaluated for the sake of neutrality and fairness.


Logitech G403 vs G703 Wireless

Though the G403 and the G703 have wireless technologies equipped altogether, each device has a different level of wireless, as defined by Logitech. For the G403, it claims to have lag-free wireless that’s 2.4GHz fast with a report rate of only 1 microsecond. Usually, the said report rate can only be attained by wired gaming mice as it’s common knowledge that data transfer done on air has its stability issues. However, Logitech found a way to eliminate that perception and pioneered a wireless technology that began in the G900 Chaos Spectrum.

As for the G703, it carries Lightspeed Wireless technology, an innovation that required Logitech engineers to optimize the connectivity of the mouse from the sensor, to the firmware, from circuitry, down to the antenna. Meaning, each of the component that’s essential to transferring wireless data were tested until none of the valuable parts are detrimental to providing the optimum report rate.

Logitech G403 vs G703 Optical Sensor

Both the two mice from Logitech have the same PMW3366 optical sensor. In a nutshell, this provides one of the best feats in the market. The advanced sensor comes with zero smoothing, filtering, and acceleration from the lowest to the highest DPI you could imagine; being 200 to 12,000 DPI. In turn, you get to experience powerful tracking accuracy that’s consistent regardless of the speed being supported. These features make the two G Series mice from Logitech a must for eSport players and local gamers alike.


Logitech G403 vs G703 Power

Power source is one of the greatest distinctions between the G403 and the G703 with each being different from one another. The G403, a mouse of an earlier release, tends to be powered by means of using a charging cable that also serves as a data cable. When the said mouse is fully charged, it can stay lit for as long as 32 hours, without light, and 24 hours when the Lightsync feature is activated. That would not be much of an issue as charging time is fast, being at 2 hours from zero to full.

As for the G703, it resorted to using the Powerplay technology where the wireless charging mouse can be consistently at full charge with a Qi-capable, USB connected mousepad. Resorting to this innovation would keep the mouse unplugged forever as you get to use and charge the mouse at the same time.

Logitech G403 vs G703 Ergonomics

Ergonomics, comfort, and user dynamics is one of the things that Logitech is famous for when it comes to satisfying user needs. In the case of the G403 and G703’s exterior build, both mice have rubber grips, located on the left and right portions of the mouse, to provide stability when playing agile and speed-demanding video games that often shake the gaming mouse at extreme levels. Shape is also an important factor in forming a mouse as it determines the comfort a user feels, oftentimes tested through long use, which raises stress levels to the palm, the fingers, and the pulse. Fortunate enough, the G403 and the G703 were created to provide that optimal comfort by focusing on the top arch of the mouse to fit the hands of most gamers, utilizing user-friendliness regardless of mouse grip and style.

Another element that makes a gaming mouse comfortable to use is through the mechanisms involved when clicking buttons or using the mouse wheel. In this regard, Logitech uses mechanical button tensioning in order to keep the left and right mouse buttons firm and easy to click. What this technology does is that metal springs help the buttons produce clicking sensations that lessens needed force, at the same time, reduces the response time and keeping it parallel to the human touch.

Logitech G403 vs G703 Customization

Through the Logitech Gaming System (LGS), customizations can be done for both the G403 and the G703 when it comes to lighting, the six programmable buttons, along with the DPI settings.

For Lightsync, you could enable settings that synchronizes with motions and movements made within the game. Not only does LGS help you choose how colors would respond to the game, but you also have the power of choosing which colors to display, as well as configuring the transition between colors.

There are six programmable buttons for the two wireless gaming mice from Logitech. So that’s the left and right buttons, the scroll wheel button, the DPI switch button, and the two grip buttons that are accessible through your thumb. With the help of the LGS, you could add some set of button sequences, also known as macros, to help you access in-game commands that take some three or four clicks to engage – such as purchasing and equipping weapons, tapping into spells, or shortcutting moves that spend a little more time clicking.

DPI settings can be configured within LGS and you could decide as to how many steps your DPI can be adjusted, maximum of five. This is particularly helpful for those who are into playing first person shooting games that shift from fast to slow in a heartbeat, especially when wielding snipers or speedy melee engagements that change from chase to attack.

You could save up to 3 profiles in your mouse, and with onboarding memory enabled, these saved profiles can be accessible within your mouse regardless if you plug in your wireless gaming mouse on a different system.

Both the G403 and the G703 provides extra personalization; and that’s the additional 10g weight that can be added close to the sensor at the bottom. This is done to compensate for the light body the mouse has, with users looking for the option of making the mouse a little heavy for “the feel” of the games they play.

Logitech G403 vs G703 Specifications

The G403 is 124mm long, 68mm wide, and 43mm high and it weighs 107.2 grams without cables and the additional 10-gram weight. On the other hand, the G703 is 124mm long, 68mm wide, and 43mm high – having the same specifics, which notes that the difference is mainly in the finer details. The latter mouse is 107 grams, 0.2 grams lighter than the G403.

Both have cables for charging with the G403 being at 1.83 meters long, a little longer than the G703’s charging cable at 1.80 meters.

Logitech G403 vs G703 Compatibility

Another level of difference between the G403 and the G703 is the operating system support catered by both gaming mice. The G403, an older model, could support Windows from 7, to 8, 8.1, and Windows 10. The G703 has a wider array of supported operating systems apart from Windows. The Powerplay ready mouse can also work with macOS 10.11 and above, as well as Google’s operating system, the Chrome OS.

Logitech G403 vs G703 Package Inclusions

When it comes to sending the whole package, the G703 has more in store than to those who are having the G403. Both have the gaming mouse in the box, as well as the charging/data cable for each. There’s also the 10-gram optional weight, as well as the User Documentation for device details and some troubleshooting.

For the wireless adapters, the G403 includes a wireless USB adapter, while the other has the Lightspeed USB adapter. As for extra adapters, there’s a cable adapter for the older model mouse, while the G703 gets an optional receiver extension adapter. If that’s not enough to get you excited with newer technology, then Logitech also included a 2-year limited hardware warranty for the G703.

So which Logitech Mouse is the Best?

Because the G403 and the G703 came from the same company, many specs and features are the same. However, when it comes to the deployment of charging technologies, the G703 sets itself far off with wireless charging that’s embedded through the mousepad with the help of Lightspeed. The latest innovation literally keeps the mouse alive to almost forever, with charging that consistently powers the battery.

In addition, the G703 was created to last a long time with left and right mouse buttons tested to endure over 50 million clicks, against the G403 with only 20 million clicks to last. Though both mice are designed to last, the difference in the figures are quite obvious, especially considering that the finishing, the mechanisms, the texture, and the overall performance are the same. With that in mind, it’s all up to preferences beyond the mouse – such as budget limitations and gaming expertise.
