Logitech Signature M650 L Wireless Mouse, Wireless + BT Connection Silent Touch

The Logitech Signature M650 L is a full-size wireless ergonomic mouse designed specifically for large right hands — delivering SilentTouch quiet clicks, SmartWheel adaptive scrolling, dual wireless connectivity via Logi Bolt USB receiver and Bluetooth, 4000 DPI Advanced Optical Tracking, 2 programmable side buttons via Logi Options+, and up to 24 months of battery life from a single AA battery. For home office users, professionals, and everyday computing users who want a comfortable, quiet, all-day mouse without compromising on feature depth or connectivity flexibility — the Signature M650 L is the right-sized solution.

DESIGNED FOR LARGE HANDS — FULL-SIZE RIGHT-HAND ERGONOMIC

The Signature M650 L is the large-hand variant of Logitech's Signature M650 series — sized and shaped specifically for users with large right hands who find standard mice uncomfortable or cramped during extended daily use. At 118.7 × 66.2 × 42mm, the M650 L's contoured full-size body supports the natural shape of a larger hand — distributing grip pressure across the palm and fingers evenly for fatigue-free comfort across full working days and extended sessions. The soft thumb area and rubber side grips keep the hand seated securely in the ergonomic shape without requiring active gripping effort.

SILENTOUCH TECHNOLOGY — 90% QUIETER CLICKS

SilentTouch Technology reduces primary left and right click noise by 90% compared to standard mouse clicks — independently tested at 1m. SilentTouch eliminates the audible click that disrupts colleagues in open-plan offices, family members in shared home spaces, and meeting participants during live calls. Full tactile feedback is preserved — you feel every click clearly and register it accurately without the acoustic footprint of a conventional mouse. The two programmable side buttons (Back/Forward) are also SilentTouch-equipped — the entire button set operates quietly.

SMARTWHEEL — PRECISION SCROLLING AND FREE-SPIN IN ONE WHEEL

SmartWheel automatically adapts between two distinct scrolling modes based on scroll speed:

- Line-by-line precision mode: slow, controlled scrolling for accurate document navigation, spreadsheet cell-by-cell movement, and code browsing where precise position control matters

- Free-spin high-speed mode: activated by a fast flick of the wheel — the scroll wheel spins freely at high speed for rapid navigation through long web pages, large documents, and extended spreadsheets

SmartWheel mode switching is automatic — no button press, no toggle — the wheel responds to scroll input speed and switches mode accordingly. The result is a single scroll wheel that handles both precision work and rapid document traversal without compromise.

DUAL WIRELESS — LOGI BOLT + BLUETOOTH LOW ENERGY

The M650 L connects via two independent wireless methods:

- Logi Bolt USB-A receiver: plug the included nano receiver into any USB-A port — instant, reliable 2.4GHz connection at up to 10m range. Up to 24 months battery life on a single AA battery. Logi Bolt's encrypted wireless protocol provides interference-resistant connectivity even in RF-congested multi-device office environments

- Bluetooth Low Energy (BLE 5.0): pair directly to any Bluetooth-equipped laptop, tablet, or desktop without occupying a USB port — up to 20 months battery life. Ideal for devices without USB-A ports or users who prefer a dongle-free setup

Switch between Logi Bolt and Bluetooth via a connection mode toggle — useful for switching between a desktop (Bolt receiver) and a tablet or secondary laptop (Bluetooth) as part of a dual-device daily workflow.

4000 DPI ADVANCED OPTICAL TRACKING — SMOOTH, ACCURATE CURSOR CONTROL

Logitech Advanced Optical Tracking delivers smooth, precise cursor movement on virtually any surface — eliminating the need for a mousepad while maintaining consistent tracking accuracy across standard desk materials, wood, laminate, and fabric. DPI is adjustable between 400 and 4000 via Logi Options+ for users who prefer slower, more precise cursor movement at lower DPI or faster navigation across large or multi-monitor setups at higher DPI.

2 PROGRAMMABLE SIDE BUTTONS + LOGI OPTIONS+

The two side thumb buttons are factory-set to Back/Forward browser navigation — the most common assigned function. Via the free Logi Options+ application (Windows and macOS), both side buttons can be remapped to any function: copy, paste, screenshot, application launch, custom keyboard shortcut, or any other supported action. Logi Options+ also enables application-specific profiles — the same button can perform different assigned actions automatically depending on which application is currently in focus.

24-MONTH BATTERY LIFE — SINGLE AA BATTERY

The M650 L runs for up to 24 months on a single pre-included AA alkaline battery with the Logi Bolt receiver — one of the longest battery lives in the wireless office mouse category. The LED battery indicator alerts when battery level is low. A single battery change approximately every two years minimises the maintenance overhead of wireless mouse ownership.
