Logitech MX Anywhere 3S vs MX Master 3S Compared

What actually differs

The Logitech MX Anywhere 3S and the Logitech MX Master 3S are two tiers of the same Logitech line. Tom’s Hardware gives the fullest side-by-side in our set, calling the Anywhere the Master’s little sibling, with a more compact and portable form, a slightly lower price and fewer features 1. The same passage says the Anywhere reuses the Master’s scroll wheel, silent buttons, 8,000 DPI sensor and Logi Options+ software 1. RTINGS’ Anywhere review and Tom’s Guide’s Master review also make brief direct comparisons 23.

That means the real trade is size and control count, not core technology. The sections below separate what a single outlet said about a single product from what a source actually compared. Where two spec sheets can be set side by side, each is cited. Where they cannot, the page says the question is unsettled.

Which is easier to carry?

Logitech’s spec pages list 95 g for the Anywhere (85 g without its battery) and 141 g for the Master 45. Subtracting one from the other gives 46 g, which matches the figure in Tom’s Hardware’s review 1. Measurements land close to the published figures: RTINGS recorded 93.7 g for the Anywhere and 141.2 g for the Master, while Trusted Reviews and Digital Camera World list 99 g for the Anywhere 2678.

On how that plays out in a bag, PCWorld says the Anywhere is easy to travel with and still the best travel mouse around for those willing to pay 9. RTINGS compares the two directly, calling the Anywhere smaller, lighter and designed more with portability in mind than the Master 2. PCWorld’s verdict covers the Anywhere alone, but the weights above point the same way. Weight also cuts against the Master in other settings: Digital Trends lists it as too heavy for some, and a reader comment under Tom’s Hardware’s Master review asks for a version near 100 g 1011.

Winner: the Logitech MX Anywhere 3S, on the spec sheets and on Tom’s Hardware’s own comparison.

Which is more comfortable?

RTINGS’ Anywhere review is the only direct comparison of ergonomics in our set. It describes the Master as having a larger, more ergonomic right-handed shape and the Anywhere as smaller and lighter with a symmetrical one 2. That is a single-source view of shape, and the hand-size notes below still apply. Each mouse also has its own record. For the Anywhere, Trusted Reviews calls the shape well suited to small and medium hands and says buyers with larger hands should look at bigger mice, while Digital Camera World says it fits an average hand 78. Tom’s Guide found it uncomfortable after a couple of hours, because there is no thumb or pinky rest 12.

For the Master, TechGearLab rated comfort 9 out of 10 for its medium- and extra-large-handed panel but said it felt slightly big for smaller hands 13. Digital Trends lists extreme comfort among its pros 10. TechRadar lists a fit problem for smaller hands among the cons 14. Tom’s Guide’s reviewer, who has wrist problems, said the Master’s ergonomic angle is not steep enough to relieve chronic pain 3.

Handedness is the one point where the published specs differ cleanly. XDA and Geek Culture describe the Anywhere as ambidextrous, although Tom’s Guide’s spec box for it says right-handed 151612. TechRadar and Tom’s Guide both count the Master’s right-handed-only shape as a drawback, and TechRadar’s left-handed reviewer points to the Logitech Lift instead 143.

Winner: not settled on overall comfort. RTINGS calls the Master’s shape the more ergonomic of the two, but hand size decides it. For left-handed buyers, the Anywhere is the one described as ambidextrous 1516.

Which has the better controls?

This is where Tom’s Hardware’s comparison favors the larger mouse. It credits the Master with a plethora of customizable buttons and a side thumb wheel, then lists the lack of a horizontal scroll wheel among the Anywhere’s cons 1. RTINGS likewise says the Anywhere’s wheel lacks left and right tilt, and Tom’s Hardware’s Master review lists the secondary scroll wheel among its pros 211.

Logitech’s spec sheets count 6 buttons for the Anywhere and 7 for the Master 45. The Anywhere’s count is contested: Tom’s Guide’s spec box says 3, and its reviewer lists few buttons as a con 12. PCWorld thinks the Anywhere has too few buttons for Smart Actions to be useful 9.

The Anywhere does have one control edge reported by a single outlet. Tom’s Guide’s Master review says the Anywhere let its reviewer change the ratchet weighting, which the Master did not 3. Tom’s Guide’s Anywhere review confirms that Options+ adjusts the haptic feedback of the ratchets 12. Tom’s Hardware and Tom’s Guide both say the two mice share the same scroll wheel, yet the sources disagree on details: RTINGS reports tilt on the Master’s main wheel but not the Anywhere’s, and Tom’s Guide reports ratchet tuning on the Anywhere only 132.

Winner: the Logitech MX Master 3S, for the thumb wheel, wheel tilt and extra button; the Anywhere keeps a small edge on ratchet tuning.

How do battery life and connectivity compare?

Logitech’s listing for the Anywhere says up to 70 days, and TechGearLab reports the same manufacturer claim for the Master 413. Logitech’s Master spec page itself states only three hours of use from a one-minute charge, and How-To Geek and Digital Camera World cite the same quick-charge figure for the Anywhere 5178. Because no reviewer ran either battery to empty, the 70-day number is a claim, not a result.

Real-world estimates sit well below it for both. EFTM had 60% left on the Anywhere after about two weeks and expects roughly four weeks of use 18. Tom’s Guide estimated about four weeks for the Master from its own week of use 3. Those estimates use different methods, so they should not be read as a draw or as a ranking. Reviewed found only 8% drain on the Master after a week, and Trusted Reviews never had to charge the Anywhere over a couple of weeks 197.

Connectivity is similar on paper: both list Bluetooth Low Energy and a Logi Bolt receiver 45. The difference is the box. PCWorld and XDA report no receiver with the Anywhere, and XDA adds that the mouse has nowhere to store one 915. RTINGS agrees that the Anywhere ships without one and adds that most people will not notice a difference from Bluetooth, while its variant table shows a Bolt receiver in the box with the standard Master 3S but not the For Mac or Bluetooth Edition versions 26.

Winner: a tie on rated battery and wireless options; the standard Master 3S has the edge on what ships in the box, according to RTINGS.

What about the sensor, surfaces and gaming?

Both spec sheets list a maximum of 8,000 DPI, and Tom’s Hardware says the sensor is shared 451. PCWorld doubts that resolution matters in a mobile setting, and TechRadar says most users will not need the full range 914.

On surfaces, both mice are reported to track on glass. XDA, EFTM and Geek Culture report glass tracking for the Anywhere, while TechGearLab saw the Master track on a clear glass table 15181613. Logitech attaches a 4 mm minimum glass thickness to the Master’s claim while the Anywhere’s page promises any-surface tracking without naming glass 2021.

For gaming, RTINGS locks its polling-rate and latency figures for both mice behind a membership, so we have no readable numbers to set side by side. Tom’s Guide played a shooter at about 4,500 DPI on the Anywhere and found it fast enough for casual use, adding that the Razer Pro Click Mini and Corsair Harpoon offer higher DPI and are better alternatives if it is not 12. On the Master, the same outlet found the sensitivity adequate for close quarters and recommended a dedicated gaming mouse for competitive play 3.

Winner: a tie on sensor and glass; gaming is unsettled, with Tom’s Guide treating both as casual-play options only 123.

Which costs less?

Logitech’s US page showed $89.99 for the Anywhere when accessed on October 8, 2026 21. The Master page, accessed September 21, 2026, rendered as the Bluetooth Edition listing, with $99.99 struck through as the list price and $89.99 as the price shown 20. Those dates differ and Logitech’s prices change, so treat the $10 list gap as approximate. Tom’s Hardware put the Anywhere at about $20 below the Master when it reviewed it at $79, which is a launch-era figure 1.

Value verdicts are separate for each mouse. Trusted Reviews, PCWorld and Tom’s Guide each list the Anywhere’s price as a con, while How-To Geek lists a fair price as a pro 791217. For the Master, Tom’s Guide lists it as pricey, while Tom’s Hardware credits Logitech’s software as the reason it remains worth a premium 311.

Winner: the Logitech MX Anywhere 3S on sticker price; which gives more value for the money is not settled.

Which one to buy

Choose the Logitech MX Anywhere 3S if the mouse goes in a bag, or if you use your left hand, since XDA and Geek Culture call its shape ambidextrous 1516. Choose the Logitech MX Master 3S if it mostly sits on one desk and you want a thumb wheel and a seventh button, and your hand is large enough for a bigger body. Nothing above supports naming one the better mouse overall: the Anywhere wins on weight and sticker price, the Master wins on controls, and comfort, battery, sensor and gaming are tied or unsettled.
