Samsung Gear IconX Earphones

Beyond smartphones, the two gadgets you see most often at the gym are fitness trackers and headphones. Samsung Gear IconX Earphones combine these two into a compact package. The 'phones have 4GB of internal storage, so you can play music without taking your phone with you, and built-in sensors record data like heart rate, distance, speed, and calories burned. Of course, you can also stream music to them over Bluetooth, an ambient sound mode ensures you can hear what's going on around you when you're running on/near the road, and the included carrying case doubles as a charger, giving you two extra top-offs before you need to find an outlet.
