If you've spent any amount of time traveling abroad, you've likely run into a language barrier, making it hard to get the most out of your trip. With the Sigmo Voice Translation Device ($50) you can avoid those issues, without resorting to learning a new language. This device connects to your iOS or Android device over Bluetooth and, using existing services, translates your voice into one of 25 different languages. Just speak into the microphone and it will translate everything you say, playing it back over the speaker. It's small and light, so you can bring it anywhere, attach it to your clothes, or hang it around your neck.
