Features and Benefits of Corsair K55 and K70


The keys of the K55 are quieter than the traditional keyboard. If you need to carry your keyboard to your workplace, you can use it without trouble. No one will feel disturbed because of your typing.

The responsible keys assign your presses to register within the fastest possible time. In terms of numbers, this keyboard has 120 keys overall.

On the other hand, as the K70 is a mechanical keyboard, some sounds will be because of its Cherry MX switches. It has a total of 104 keys.   

Macro Keys

Corsair K55 will allow you to continue your actions without pause since it has 6 macro keys; besides, the K70 doesn’t include these unique keys. These keys will bring you an advantage for in-game actions. There is a dedicated Windows key-lock tool in this keyboard by which you will never be interrupted while playing any games or during a critical moment.

Palm Rest

Not just a palm rest, you are getting a soft-rubber palm rest with the Corsair K55. For extended usage, your hands will be in the comfort zone, allowing the device to last for a long duration. The palm rest is also detachable, so you can remove it if you need to carry it in a bag or don’t want to use it.

The other keyboard also has a detachable palm rest, but as the K55 is a quiet keyboard, the overall experience will be better on the K55.

Dedicated Controls

With K55, you can directly control media options like music through the keyboard. There are dedicated multimedia and volume control in the top right corner to change media options without interference between your games or other important actions.

Corsair K70 too provides dedicated keys at the top but is not well-positioned as the K55. You may have trouble using these keys.

Lighting Controls

Through iCUE software from Corsair, you can customize the color setup. You can test and apply the color synchronization from the software to direct your keyboard. 

The Corsair K70 also has these features, but the customizing may not be that simple as this is a mechanical keyboard. 

Dust Resistance

If you are worried because of dust and spill that may interrupt your actions and cause harm to your keyboard’s durability, you can relax with the K55.

This keyboard comes with an IP-42-rated protection guard that will protect your keyboard from this kind of complication.

K70 also has dust resistance, but there was no quality of measurement like the K55 has.

Warranty & Durability

Corsair keyboard has a popular fanbase for its durability. You can use these keyboards for a long time without any doubt, and Corsair provides a 2-year warranty for both the K55 and the K70. As the K55 is a relatively simple but reliable structure, you can rely on this more than the other device.


These keyboards from Corsair may appear no different from looks. K55 is a gaming keyboard with a membrane switch type, and the K70 is a mechanical keyboard with a Cherry MX switch. The K70 will cost you a lot more than the K55, but you are not missing any specs if you go for the K55. So I will highly recommend the K55 for anyone who wants performance and satisfaction.
