Logitech G403 vs G703 | Overview
Logitech’s G403 is only a couple of years older than Logitech’s G703; this was more than enough time for the brand to introduce a couple of brand-new features, as well as take in all the feedback and tweak the ones they wanted to keep.
Both models are held in high regard among gamers, writers, students, cubicle workers, and pretty much everyone who values simplicity and reliable performance over flashy features. The following sections aim to explain why G403 and G703 are some of the finest Logitech PC mouse available, as well as shed some light in terms of their differences, similarities, and ultimately – value for the buck. in this Logitech G403 vs G703 comparison review.
Logitech G403 vs G703 | Key Features Comparison
Design & Size
The first round of performance tests we ran concerned the size and design of both mice. As far as aesthetics and dimensions are of concern, G403 and G703 are absolutely identical.
The actual dimensions of Logitech’s G403 and G703 measure 4.9 inches in length (124 millimeters) by 2.8 inches in width (68 millimeters) by 1.7 inches (43 millimeters). The weight is the first difference we were able to spot, specifically regarding the G403 wired variant.
G703 and the wireless variant of G403 weigh 3.38 ounces (96 grams) while the wired G403 weighs only 3.1 ounces (87 grams). Obviously, the wireless variants feature a battery (which roughly weighs around 0.2 ounces) that is responsible for the added weight. Even so, both G403 variations alongside the G703 could easily pass as lightweight mice.
In terms of design and ergonomics, there are no apparent differences between these two. They sport a plain, straightforward design that is characterized by smoothly grooved clicks and a slight bump in the left side of the body.
These models are slightly smaller than average, but that’s precisely what makes them so easy to use in pretty much every scenario.
Construction & Durability
The next bout of performance is about sturdiness and construction of G403 and G703. Generally speaking, durability is one of the most important factors of any PC mouse, especially for people who can’t replace their now-broken ones on short notice.
In terms of construction, both G703 and G403 are made of the same materials – rugged plastic was used for the body, slightly softer and more flexible materials for the buttons while the cable is braided and constructed of robust synthetic materials.
Even though they appear identical at first glance, G703 is actually more than twice the click durability in comparison to the G403. While G403 (both wireless and wired models) offer a lifespan of 20-million clicks, G703 promises up to 50 million.
Comfort of use
In all fairness, there are only a few differences between G403 and G703 as far as comfort. They share the same design, they’re made of the same materials, and they sport identical (physical) features.
The only thing that separates the two in this field is the lack of a cable in the wireless models. The wireless models can be used in more flexible ways. The G403, is also just a tad lighter.
However, it wouldn’t hurt to mention that one of the minor drawbacks in the design of G403 and the G703 model’s is neither of the two come supplied with rubberized sides or a textured bodies.
Even though both mice are very comfortable to use as-is, we believe the addition of such features would significantly enhance their performance and comfort rating.
Sensors
A huge part in any mouse performance is determined by the sensor they are equipped with. First and foremost, the wired G403 version and G703 feature Logitech’s proprietary HERO sensor while the wireless version of G403 packs the PMW3366. Let’s have a quick rundown of these two before we put them back-to-back.
Pixart PMW3366 is the sensor installed in several Logitech models, including G303 and the wireless G403. Basically, this sensor succeeded the AM010, which was already held in high regard among gamers and students due to its exceptional tracking abilities and impeccably smooth operation.
While PMW3366 is considered to be one of the most versatile sensors, it has a couple of drawbacks that have been addressed by the Hero. Namely, it struggled to identify small movements; rather, the PMW3366 ‘accumulates’ them before converting them into a motion.
On a more positive note, Pixart PMW3366 is drastically more precise when tracking big, rapid movements. Be it as it may, it’s still an excellent sensor that is well-suited for most applications.
The HERO sensor the comes with both the wired G403 and G703. Even though it may not be perfect, it eliminates PMW3366’s shortcomings and brings a myriad of fresh benefits to the table.
One of the biggest innovations of the Hero sensor was optimization and reduction in its smoothing, acceleration, and filtering segments. It offers remarkable tracking speed and boasts nearly unequaled accuracy on the same field while being superior in terms of power efficiency in comparison to earlier generations of Logitech mice.
Another reason why it’s absolutely loved by the Logitech enthusiast community is the fact that it offers the same level of performance across all DPI ranges. Its responsiveness is on a completely different level when compared to Pixart PMW3366, and we daresay this is generally a better sensor overall.
Sensitivity (DPI)
The DPI rating of a PC mouse tells us everything we need to know about its sensitivity. Essentially, the Dot-per-Inch abbreviation refers to pixels a mouse will move on the screen per inch you move the mouse in real world.
For example, a mouse with 2,000 DPI will move 2,000 pixels when you move it an inch. This is, however, not everything DPI rating tells us. Most manufacturers point out the upper DPI rating level so as to make the model more appealing to competitive gamers. The lower DPI rating is equally important, as lower sensitivity levels allow the mouse to accurately recognize smaller movements.
Once again, the wired G403 and G703 stand on equal footing – their DPI range spans from 100 – 25,600 DPI.
Knowing that many people aren’t exactly sure whether this is good or bad, so let us compare it to DPI levels of an average PC mouse range from 400 to 8,000. In that light, G403 and G703 offer several times more flexibility and versatility, allowing you to fine-tune the performance of your mouse with ease.
Programmable Buttons
The versatility of a mouse can also be measured by its programmable features. The range of applications of these programmable features is huge – gamers typically use them to assign macro commands, writers can link commands such as ‘copy’, ‘paste’ or ‘link’ to them easily while everyone can benefit from the DPI toggler.
Both G403 versions and G703 come supplied with a total of six programmable features. The two clicks, of course, two programmable buttons at the thumb-side, the clickable wheel button, and the DPI sensitivity changer right underneath it.
The buttons on the G403 and G703 have identical button features and are located in identical positions.
Logitech G403 mouse in a Nutshell
Essentially, G403 is a terrific all-around gaming mouse that offers remarkable value for your dollar. It’s a relatively inexpensive PC mouse that works like a charm for gamers, editors, writers, and students, and to be completely fair, we were surprised that it comes supplied with almost the same features as G703 whilst being considerably cheaper.
Aside from affordability, we really loved the fact that it’s available in both wireless and wired formats. However, these two models share more differences than similarities between themselves, which made the wireless model more suitable for a separate review.
The wired G403 is outfitted with the heavily-acclaimed HERO sensor, it’s slightly lighter than the G703, and it offers the same dimensions and DPI range. However, even though it’s made from the same materials, it doesn’t offer the same level of durability as the G703.
We love this particular model for everyone who may be looking for an upgrade, be it for traders, competitive hard-core gaming, multi-tasking video editors or students.

Logitech G703 mouse in a Nutshell
The G703 picks up where G403 left off – it’s a younger model that is more than well-suited to be called its successor – it packs a variety of quality improvements and enhancements alongside the features we loved in the G403.
Let’s start off with familiar characteristics of this PC mouse – as far as size is of concern, this mouse is identical to G403. It also weighs the same and packs the same programmable features (two click buttons, two thumb-side buttons, DPI changer, and clickable wheel button).
Furthermore, its DPI range spans from 100 – 25,600 dpi – the same can be said about the wired G403. Another similarity between the two is the HERO sensor, which surpasses most previous Logitech sensors in terms of performance.
Some of the most notable improvements regarding G703 include dramatically enhanced click durability and major tweaks to its tracking capabilities. Namely, the rugged plastic construction on the clicks of G703 afford it the durability rating of approximately fifty million clicks, which is more than twice as much in comparison to G403.
The improved tracking eliminated the G403’s inability to follow miniature hand movements. As we mentioned earlier, this mouse ‘stores’ mini-movements and then executes a single stroke. This made it less accurate for precision work. Luckily the improved software of G703 fully addresses this issue.
The G703 wireless is compatible with the Logitech powerplay wireless charging system. This system continuously charges the mouse while its being used. Eliminating the need to manually recharge or run out of battery.
What we didn’t like so much about it is the fact that it’s basically a more expensive G403 model. To a degree we understand the need to retain the same design and aesthetics; it’s also understandable for the dimensions to be identical; however, the majority of features that G403 is supplied with are present in G703 as well.
Even though there are some undeniable improvements, it’s a more expensive mouse that offers roughly the same benefits as its cheaper counterpart.
