Logitech MK955 Signature Slim Wireless Keyboard and Mouse Combo Review

TL;DR

The Logitech MK955 Signature Slim Combo pairs the K950 low-profile keyboard with the M750 wireless mouse. Both pair to up to three devices via Bluetooth or Logi Bolt, and both run on AA/AAA batteries you can swap in seconds. It is built for hybrid workers, not gamers.

Why It Matters

Most "wireless combos" are afterthoughts — mushy keys, unusable mice, mystery dongles. The MK955 is different because both halves are real Signature-line products in one box. If you have been hunting for a quiet, low-profile setup that survives a multi-laptop life, this is a clean answer.

Key Specs

• K950 keyboard: full-size with number pad, low-profile keys
• M750 mouse: 4,000 DPI, 5 buttons, SmartWheel scroll
• Multi-device: pair up to 3 devices, switch with Easy-Switch keys
• Connectivity: Bluetooth Low Energy or Logi Bolt USB receiver (one receiver works with both)
• Battery: keyboard ~36 months on 2x AAA, mouse ~24 months on 1x AA
• OS support: Windows, macOS, Linux, ChromeOS, iPadOS, Android

Pros

• Genuinely quiet typing for shared spaces
• Single Logi Bolt receiver handles both devices
• Easy-Switch lets you jump between laptop, desktop, and tablet
• Multi-year battery life on cheap replaceable cells
• Logi Options+ lets you remap keys and mouse buttons per app

Cons

• No backlighting on the keyboard
• Mouse is comfortable but not contoured for large hands
• Low-profile keys take a session to get used to if you come from mechanical
• Plastic build is light — not a premium feel

Who It's For

Hybrid workers, shared-office users, and anyone who hates desk noise. Also great if you have a laptop, a desktop, and an iPad and want one keyboard and one mouse that handle all three. Heavy gamers and mechanical-keyboard fans should look elsewhere.

How to Use It

Install Logi Options+ first. Pair the keyboard and mouse to slot 1 (Bolt receiver), slot 2 (Bluetooth to laptop), and slot 3 (Bluetooth to tablet). Tap the Easy-Switch keys to flip between machines mid-task. Remap the mouse thumb button to gesture-trigger Mission Control or Task View — that single change is worth installing the software.

How It Compares

Versus the cheaper MK540, the MK955 has multi-device support and quieter keys. Versus the MX Keys + MX Master 3S, it costs roughly half but skips backlighting, the sculpted mouse shape, and the rechargeable batteries. As a productivity workhorse, it lands in a strong middle.

Bottom Line

A quiet, multi-device combo with absurdly long battery life and one receiver for both pieces. The MK955 is the easy recommendation if your daily life involves more than one computer.
