Soundcore Anker Space One Headphones are $139.99, down from $199.99, which is 30% off. That's the lowest price in 90 days. They have noise cancellation that senses your surroundings and changes how much it blocks as you move between airports, offices, and streets. The drivers are Hi-Res certified up to 40 kHz, and LDAC in the free soundcore app gives you CD-quality wireless streaming. The headband flexes without clamping, and the soft protein leather ear cushions use slow-rebound foam. Battery life is 40 hours with ANC on and 60 hours with it off, and 5 minutes of charging gives you 8 hours of playtime.

The Gyokucho Razor Saw is $18.99 right now, down from $30.20, which is 37% off. That's the lowest price in a year. It's a Japanese pull-stroke saw, so it cuts as you pull and the thin .5mm blade stays straight instead of bending. It's two saws in one. The finer-tooth side handles crosscuts, and you flip it over for rip cuts. Our reviewer liked that you get clean results without expert technique.

Anker's 621 MagGo Power Charger is $29.99 right now, down from $42.99, which is 30% off. That's the lowest price in six months. It's a magnetic battery that snaps onto the back of an iPhone 14 or 15 and charges wirelessly at up to 7.5W. The magnets are strong enough to hold on while you take selfies or make calls. It measures 4.13 by 2.62 by 0.45 inches and weighs 4.41 oz, so it fits in a pocket. Anker's MiniCell technology packs the same charging performance into fewer parts, which is how it got smaller and lighter. A 23.6-inch USB-C cable comes in the box with a 24-month warranty.

Building Block Bricks 54 Roof is $24.99 right now, down from $34.99, which is 29% off. That's the lowest price in six months. This is a bulk set of 1,000 plastic bricks in 10 colors, with 54 roof tiles and 9 different brick sizes mixed in. KK picked it as a cheaper way to get big quantities of bricks, and said "any of them will be perfectly acceptable substitutes for real Lego if you need large quantities." The bricks fit with the major brands, so they snap onto sets you already have. The 1,000 pieces work out to about 2.5 cents each at the sale price.

The Aluminum Grip Ruler is $20.04 right now, down from $25.75, which is 22% off. That's the lowest price in a year. It's a 30 cm aluminum ruler with grip along its whole length, so it stays put when you press on it with a pen or a knife. Cm and inch markings run down the edge. Nabhan Islam called it "sheer utility-per-dollar" in Cool Tools, and said it does the trick. He missed the solid heft of steel, but the ruler isn't flimsy.
