Overview
The ATTACK SHARK X86 75% Wireless Mechanical Keyboard packs an 84-key 75% layout, a CNC aluminum alloy (6063) frame, gasket mounting, tri-mode connectivity, hot-swap sockets and a 4000mAh battery into one board. In short, it suits people who want a quiet wireless 75% keyboard with an aluminum body.
The factory-lubed matcha linear switches have a 45gf actuation force and a listed life of 50 million presses. A light linear switch feels smooth for both gaming and typing. The five-layer damping structure is rated below 35dB; that figure is the manufacturer's claim, and real-world sound depends on your desk and environment.
On Amazon.co.jp, it had 18 reviews averaging 4.0 out of 5 (about 80%) as of October 8, 2026. With so few reviews, treat the rating as a rough guide.
Feature Breakdown
Gasket mount and 5-layer damping
A gasket mount holds the plate and PCB on cushioning rather than rigidly screwing them to the case. This softens bottom-out impact and tends to give a cushier feel. Combined with multiple damping layers, the sound leans toward a lower, muted tone instead of sharp clacking.
This helps for late-night work or shared rooms. If you prefer a firm, snappy feel, it may seem too soft.
Matcha linear switches
45gf is a middle-of-the-road weight. Linear switches have no bump, which suits rapid inputs. But light linears can cause accidental presses when resting fingers, so heavy typists may want to swap in heavier switches.
Hot-swap
The sockets accept 3-pin and 5-pin switches without soldering. Use a switch puller and pull straight up so you don't bend the pins.
Connectivity and Battery
Three modes are available: Bluetooth 5.0 (up to 3 devices), 2.4GHz (1ms response as advertised) and wired USB-C. Wired mode works for charging while typing. A 4000mAh cell is large for this class, but runtime varies greatly with backlight brightness and connection mode, so lowering RGB brightness is the realistic way to stretch it.
Compatibility Guide
It supports Windows 11/10/8/7, macOS, iOS and Android, and basic typing needs no extra software.
- There is no numpad, so heavy spreadsheet users may need a separate one.
- On iOS and Android, use Bluetooth.
- On macOS, check the modifier key layout on the product page before buying.
- Detailed RGB and key remapping depend on the maker's configuration tools; confirm support on the listing.
Check that replacement keycap sets cover the 75% layout's key sizes.

Best Use Cases
- Desk-space savers: the 75% layout keeps function and arrow keys while freeing room for the mouse.
- Quiet-environment users: the damping and gasket design favor a muted sound.
- Multi-device users: Bluetooth for three devices plus 2.4GHz and wired modes.
- Beginners to customization: hot-swap and an aluminum case make a good entry point.
- Look elsewhere if: you need a numpad, want a crisp, firm feel, or value strong local after-sales support.
Before You Buy
First, the 75% layout is tightly packed around the arrow keys, so misses are common until you adapt. Second, 18 reviews is too few to judge long-term durability or battery life; test each connection mode right after delivery. Third, the seller is KASUAYA本店, and domestic support from the maker is not guaranteed, so check warranty and return terms. Finally, specs such as 35dB are manufacturer figures without stated test conditions. Listing data can also contain errors, so confirm the product (X86, Star Black) by title and images before ordering.
