Description
A4Tech OP-550S Silent Optical USB Mouse โ Quiet Clicks for Focused Work
The A4Tech OP-550S is the silent-click version of A4Tech’s popular OP-550 office mouse. It does everything a dependable wired mouse should do, with one difference you’ll notice from the very first click: the buttons are near-silent, cutting click noise by around 90% compared to a normal mouse. If you share a room, work late while others sleep, or sit in a quiet office or library, that quiet click makes a real difference.
Silent mice have caught on fast in Bangladesh โ students in hostels and shared flats, freelancers on late-night calls, call-centre and co-working staff, and anyone who’s ever been told to “stop clicking so loudly” during an online class. The OP-550S solves that small but constant annoyance without asking you to pay premium prices.
Built to Last, Not Just to Sell
A4Tech rates the OP-550S buttons for over 5 million clicks, so this isn’t a mouse that starts double-clicking after a few months. The scroll wheel uses a dust-resistant design that keeps scrolling smooth over time, and the base rides on Teflon feet for an effortless glide across your desk or mouse pad.
The 1200 DPI optical sensor tracks accurately on almost any surface โ wood, fabric, laminate โ so you get steady cursor control whether you’re editing documents, browsing, or working through spreadsheets. It’s a symmetric shape too, which means it sits comfortably in either hand.
Plug In and Go โ No Setup Needed
Connection is simple USB-A plug-and-play. Plug it into any desktop or laptop, and Windows recognises it instantly โ no drivers, no software, no fuss. The generous 150cm cable gives you plenty of reach, whether your PC sits on the desk or under it.
