PRODUCT DESCRIPTION

Logitech M221 Silent Wireless Mouse Charcoal (910-004882) - 2 Years Local Warranty

Logitech M221 SILENT Wireless Mouse — Over 90% Less Click Noise

The Logitech M221 Silent Wireless Mouse Charcoal (910-004882) takes Logitech's most widely deployed compact wireless body and removes the one thing nobody in an open-plan office misses. Logitech states that its SilentTouch Technology “reduces over 90% of clicking sounds” — the click still has its tactile response, it simply stops carrying across the room. For Singapore's high-density office floors, shared meeting rooms and libraries, that is a small change users notice on day one.

Quiet Enough for Video Calls and Shared Desks

Logitech's noise claim is based on an independent-lab left-click measurement at one metre, comparing its silent design against a standard mouse. In practice it means colleagues on the next desk stop hearing your clicks, and microphones on video calls stop picking them up. It is the single most requested feature in SourceIT's corporate mouse refreshes.

1000 DPI Advanced Optical Tracking in an Ambidextrous Shell

Logitech specifies Advanced Optical Tracking at 1000 dpi with a 2D optical scroll wheel and controlled line-by-line scrolling. The contoured 99 × 60 × 39 mm shell is described by Logitech as suitable for both left- and right-handed users, so it works as a single fleet SKU. Wireless range is rated at up to 10 metres over the supplied USB receiver.

18-Month Battery Life on One AA

An on/off switch and auto-sleep power-saving mode stretch a single replaceable AA battery to up to 18 months — 50% longer than the standard M185 rating. Across a few hundred desks that is a meaningful reduction in battery handling for facilities teams. Logitech publishes a 3.76 kg CO2e product carbon footprint for the M221.

Frequently Asked Questions — Logitech M221 SILENT

How quiet is “silent” in practice?
Logitech's published claim is that SilentTouch Technology “reduces over 90% of clicking sounds”, measured as left-click dBA by an independent lab at one metre. The click is not removed — you still feel the same tactile response — it simply stops being audible to people around you.

What is the difference between the M221 and the M331 SILENT?
Shape and handedness. The M221 is a compact 99 × 60 × 39 mm ambidextrous shell rated for 18 months of battery. The M331 SILENT is a larger right-hand asymmetric design with a soft rubber grip, also rated at 18 months. Choose the M221 for mixed-handed fleets and travel, the M331 for right-handed users who want more palm support.

How does it compare with the M185?
Identical body and sensor. The M185 is the standard-click version rated for 12 months of battery; the M221 adds SilentTouch clicking and an 18-month rating. For open-plan floors the M221 is usually worth the small difference.

Does it use Bluetooth?
No — the M221 uses a 2.4 GHz USB receiver, so it needs a free USB-A port. If your laptops are short on ports, the M240 Silent Bluetooth Mouse offers silent clicking over Bluetooth with no dongle at all.

Which colours are available and what are the part numbers?
Logitech publishes Blue as 910-004883 and Red as 910-004884; this listing is Charcoal, 910-004882. A Rose colourway also exists but Logitech does not publish its part number. Non-stocked colours can be indented — ask SourceIT for lead time.

Do I need software, a licence or a room PC?
No. Plug in the receiver and it works. No Logitech licence, subscription or compute appliance is involved.

Does this mouse come with a Singapore warranty?
Yes. Every M221 SILENT sold by SourceIT comes with 2 years local Singapore warranty and a GST invoice.
