SainSonic has some pretty neat Bluetooth headphones here. These use bone conduction technology, and what that means is that it uses vibration to transmit audio without blocking your ears. On top of that, this headset can deliver some amazing sound without annoying you with wires and such. Definitely a good thing for doing cardio at the gym. These are headphones that are great for those that want to be able to listen to music, but don't want to cover their ears.
These headphones aren't just headphones though, they also have a built-in microphone and volume control. Allowing you to take calls from the headset without needing to pick up your phone to talk to someone. You can also control the volume on these bone conduction Bluetooth headphones with ease. SainSonic has also made these weather-resistant. So no matter the weather - whether it be hot in the dessert, or snowing up North - you will be able to use these headphones without any issues. These headphones are a bit pricier than most other headphones that are on the market, they are coming in at around $69.99. Their normal price, however, sits at around $100. So definitely worth picking up from the Android Headlines Store.
