Keychron M6 Buying Guide: Wheel, Sensor, 8K, and Switch, Explained

You have probably seen the Keychron M6 on a desk setup or in a video and liked the look of it. Then you opened the product page and hit the options: two colors, two wheels, three sensors, three switches.

This guide walks those choices in the order you meet them on the page, with US list prices as of October 2026, and ends with one build for each kind of desk. Specs and prices are ours. How the mouse feels in the hand comes from owners on Reddit, linked where quoted.

What the M6 is

A right-handed wireless mouse with a thumb rest.

• Weight: 78 to 86 g, depending on version.
• Connection: 2.4 GHz receiver, Bluetooth, or USB cable.
• Battery: 800 mAh.
• Two wheels. The top wheel on the metal version has a notched mode (each click moves a set number of lines) and an infinite mode (one flick spins through thousands of lines); a button behind it switches modes. The thumb wheel on the side scrolls sideways, for wide sheets and video timelines.

Step 1 and 2: Color, then wheel

Color: black or white. Both colors cost the same. One catch: the Clicky switch with the metal wheel comes in black only, so white plus Clicky means the plastic wheel. Otherwise, match your keyboard.

Wheel: metal or plastic.

• Metal (premium): held by magnets instead of a spring. Smoother, quieter, more precise, and the only wheel we list with the infinite scroll mode.
• Plastic (standard): notched scrolling only.

The page shows the wheel as a separate choice, but it is mostly decided for you. The PixArt 3311, the PixArt 3395 in Silent and All Silent, and the PixArt 3950 all come with the metal wheel. Plastic appears only on the PixArt 3395 Clicky. So the one time you actually choose is the PixArt 3395 (1K Polling Rate) Clicky: plastic $49.99, metal $54.99 (the metal-wheel Clicky is black only).

If you scroll long documents, code, or sheets all day, take the metal wheel. One r/MouseReview user singled it out: "I can't think of any other mice that's lighter than 80g has infinite scroll wheel other than the keychron m6."

Step 3: Sensor and polling rate

Two terms, once. Polling rate is how often the mouse reports its position: 1K is 1,000 reports a second, 8K is 8,000. DPI is how far the cursor moves per inch of hand travel. The product page names each sensor with its polling rate, and we do the same below.

The three sensors, in one line each:

• PixArt 3311 (1K Polling Rate): reliable daily wireless use. Metal wheel. Silent or All Silent.
• PixArt 3395 (1K Polling Rate): the gaming and productivity balance. Metal wheel on Silent and All Silent; plastic or metal on Clicky.
• PixArt 3950 (8K Polling Rate): competitive gaming, ultra-low latency. Up to 30,000 DPI and 750 IPS. Metal wheel, any switch.

We do not publish separate DPI figures for the PixArt 3311 and PixArt 3395, so between those two choose by what each is built for (see our buying guide), the switches offered, and the price step.

Every listing on the page, US list prices, the same in both colors (Clicky with the metal wheel: black only):

What each step up buys:

• PixArt 3311 → PixArt 3395: $5 for the sensor built for people who also play.
• Adding a Clicky switch: $54.99 with the metal wheel, $49.99 with plastic.
• PixArt 3395 → PixArt 3950: $15 to $20 for 8K polling. It matters in competitive shooters on a high-refresh monitor. It costs battery: up to 120 hours at 1K, up to 35 hours at 8K. And 8K only works over the 2.4 GHz receiver; Bluetooth polls lower.

Casual games at night are fine on the 1K sensors. If competitive play comes first, the G6 HE at the end of this guide is the better tool.

Step 4: Switch

A micro switch is the small physical switch under each button that makes the click. The three names are easy to misread:

• Silent: only the left and right buttons are silent.
• All Silent: every button is silent.
• Clicky: crisp tactile feedback on every button.

Open office, shared room, calls: All Silent. Nobody hears you and you like the feedback: Clicky. Silent costs the same as All Silent; it is for people who want quiet main clicks but a normal click on the other buttons.

Size: measure before you order

122.5 mm long, 75.4 mm wide, 50.0 mm tall. Put a ruler on the mouse you use now.

• Wider than about 80 mm, and you rest your whole palm on it: expect the M6 to feel small.
• Around 75 mm or narrower, or you hold the mouse with your fingertips: the M6 is in your size class.

One r/MouseReview user called it a "smaller" shape with "lighter weight" that you can use for competitive gaming. If you rest your whole palm on a wide mouse today, measure first, and look at the vertical M5 at the end of this guide as the other shape we make.

The build for each desk

• Sheets, timelines, long documents, no games: PixArt 3311 (1K Polling Rate), metal wheel, All Silent. $44.99.
• Work by day, casual games by night: PixArt 3395 (1K Polling Rate), metal wheel. All Silent if anyone can hear you ($49.99), Clicky if not ($54.99, black only).
• Work by day, competitive shooters by night, one mouse for both: PixArt 3950 (8K Polling Rate), metal wheel, Clicky in black or All Silent in white. $69.99. If the shooters come first, see the G6 HE below.

Another Keychron mouse fits better if:

• You want lighter than 70 g with the same thumb rest: the Keychron M7, 66 g, from $49.99. No side wheel, no infinite scroll.
• Your wrist hurts and you want a vertical angle: the Keychron M5, vertical ergonomic, 95 g, from $49.99.
• You play competitive shooters first and work second: the Keychron G6 HE, 41 to 49 g, from $74.99, is built for that and is our competitive-gaming pick.

Once it arrives:

• Connect the receiver or the cable and open Keychron Launcher in a current Chrome, Edge, or Opera browser.
• Launcher is where you remap buttons, set DPI and polling rate, record macros (a sequence of keys fired by one button), and store five profiles on the mouse itself.
• Keychron Engine is the desktop app for Windows and macOS. Start with Launcher.
• Neither reaches the mouse over Bluetooth.

Day one: pick two or three DPI steps you will use (we suggest starting around 800 and 1,600), leave polling at 1K unless you are gaming on the PixArt 3950, and if you play FPS games, turn off motion correction, as our software page suggests.

Frequently asked questions

How long does the battery last?

Up to 180 hours on the PixArt 3395 and up to 165 hours on the PixArt 3311, both rated at 125 Hz polling, so expect less at 1K. Up to 120 hours on the PixArt 3950 at 1K, and up to 35 hours at 8K.

Does the plastic wheel have infinite scroll?

We list the infinite scroll mode for the metal wheel only. If infinite scroll is why you are buying, pick a metal-wheel version.

Can I configure the M6 on a Mac?

Yes. Launcher runs in the browser and Keychron Engine has a macOS version; both need the receiver or the cable, not Bluetooth.
