The Logitech G604 is bulkier and heavier than the G703.

Both the Logitech G604 (left) and G703 (right) are right-handed mice.

One look at these gaming mice and you’ll already have an idea of which one you’ll prefer. Both of them have ergonomic designs, but the Logitech G604 has a thumb rest. They are nicely curved for comfort and they have a matte finish for better grip.

Weighing 4.76 ounces and measuring 5.12 x 3.15 x 1.77 inches, the Logitech G604 is the heavier and bulkier mouse. People with smaller hands might not find this mouse to be the most comfortable. In contrast, the Logitech G703 weighs only 3.77 ounces and it measures 4.88 x 2.68 x 1.69 inches, so it’s more compact. The G703 also comes with 10g weight that you place inside the mouse if you find it too light.

A difference with their designs is the lack of RGB on the the Logitech G604 and the backlit logo and scroll wheel of the Logitech G703. You can customize the lighting of the G703 inside the Logitech G Hub software.

Features and Buttons

Designed for MMO players, the Logitech G604 has more buttons than the G703, which is designed for shooters.

The Logitech G604 (left) has four more programmable buttons on the side than the Logitech G703 (right).

You’ll need to download the Logitech G Hub software in order to utilize the features of these gaming mice. The Logitech G Hub software allows you to adjust the dpi, assign buttons, adjust the polling rate and in the case of the Logitech G703, play with the RGB settings. You can also save profiles on the mice themselves since they have onboard memories.

Both of these gaming mice have multiple programmable buttons, but clearly, the Logitech G604 is the winner here. It has 15 programmable buttons in total, and with Logitech’s G-Shift function, the number of buttons is doubled. In contrast, the Logitech G703 only has six programmable buttons. In addition to having more programmable buttons, the Logitech G604’s scroll wheel can also be unlocked and it can also be tilted. When it comes to the number of functional buttons, the Logitech G604 is clearly the winner.

The Logitech G604 offers Lightspeed and Bluetooth connectivity while the Logitech G703 can be used wired and wirelessly (Lightspeed only).


The Logitech G604 and G703 come with Logitech’s HERO 25K sensor.

The Logitech G604 (left) requires one AA battery while the Logitech G703 (right) has a built-in rechargeable battery.

When it comes to gaming, the Logitech G604 and G703’s HERO 25K is excellent. It has a dpi range of 100 – 25,600 for accuracy and better control of your sensitivity rating. Both gaming mice make use of Logitech’s Lightspeed wireless technology. The connection is lag-free, so gaming with these mice is a very pleasant experience. There’s no lag or unresponsiveness, which is important, especially when playing competitive multiplayer games.

As for the buttons, the two mice are responsive. However, the Logitech G703 has a bit of an advantage here due to its mechanical button tensioning. That said, the difference is minimal, and most people wouldn’t even feel it.

Battery life is satisfactory for both. The Logitech G604 requires a single AA battery that can last up to 240 hours in Lightspeed mode and up to half a year in Bluetooth mode. On the other hand, the built-in rechargeable battery of the Logitech G703 can last up to 32 hours, which is good enough. You can use it while charging with the included micro USB cable and it’s compatible with the Logitech Powerplay mat.


The Logitech G604 is the better overall mouse for gaming and work, but the Logitech G703 might be the better option for you if you prefer a lightweight gaming mouse.
