Etón ZoneGuard

The ZoneGuard is the first radio to translate NOAA weather alerts into both audio and visual warnings. When dangerous weather conditions approach a specified county, the half-pound radio flashes lights that correspond to the severity of the alert: green for advisory, orange for watch, and red for warning. Etón ZoneGuard $40

SmartSound Case

The SmartSound Case amplifies a smartphone speaker without sapping any battery power. A flap unfolds from the back of the plastic case and, similar to a horn, passively increases sound by up to 10 decibels. It also doubles as a kickstand. SmartSound Case $40

Kyocera Torque

With the Kyocera Torque, callers will be able to hear their conversations anywhere—even in loud rooms. In place of the phone’s speaker, an actuator sends tiny vibrations through soft tissue in the face and directly to the eardrum. Kyocera Torque $150 (with two-year contract)

Geospace Fly Max Football

The 4.4-ounce foam Fly Max Football can soar 100 yards. A hollow center allows air to move through the ball, minimizing resistance. And adjustable fins increase spin and therefore distance. Geospace Fly Max Football $20

THX Tune-Up

THX’s tune-up app simplifies surround-sound setup. After connecting a smartphone to a stereo receiver, a user enters the number of speakers in his system. The app then displays the ideal speaker layout and sends test tones to each one to make sure it’s in the right spot. THX tune-up $1.99

Korkers KGB with Vibram OmniTrax

The KGB boot adapts to varying terrains. It has swappable rubber soles, which stay in place with plastic teeth and have different treads for rock, snow, or ice. Korkers KGB with Vibram OmniTrax $230

Omega Seamaster Aqua Terra >15,000 gauss

The Seamaster Aqua Terra is the first watch completely resistant to magnetism. Engineers made the watch from nonferrous metals, which are unaffected by magnetic fields that can interfere with accuracy. It can resist more than 1.5 Tesla—about the strength of an MRI machine. Omega Seamaster Aqua Terra >15,000 gauss $6,500 (available fall)

PLAiR

The PLAiR streams any Web video to a TV. First, a user downloads the PLAiR app onto a WiFi-enabled device and plugs the accompanying dongle into a TV’s HDMI port. After the user selects a video, the app sends the relevant source URL to the dongle—a Wi-Fi receiver—which then streams the video itself. PLAiR $99

SteelSeries Apex

The Apex keyboard will improve a gamer’s response times. Background software tracks a player’s keystrokes and generates a visual map that can be used to reprogram the keyboard. For example, by moving keys that are frequently pressed in tandem closer to one another, a player could speed up keystrokes. SteelSeries Apex $100

Moen MotionSense

The MotionSense is the first kitchen faucet that cooks don’t have to touch to operate. Motion directly above a battery-powered infrared sensor on the top of the faucet turns the water on; the same motion turns it off. Moen MotionSense $399

Sony Walkman Sports MP3 Player

The waterproof Walkman Sports MP3 Player will play for eight hours at depths up to 6.5 feet. The earbuds contain both the player and battery, and an adjustable elastomer band holds them in place while swimming. Sony Walkman Sports MP3 Player $100
