The Amps Air by Sol Republic not only look great but are also ideal for on-the-go use due to their compact size and lack of cables. The two small in-ear headphones easily fit into the ear and stay securely in place during sports thanks to their special shape. Once they are in the ear, you only need an active Bluetooth connection to your iOS or Android smartphone, and you can enjoy incredibly sounding music with deep bass, just as it should be. Additionally, they feature an integrated microphone for phone calls and a button for music control (Play/Pause). The earbuds are sweat and rain-resistant and can be conveniently carried anywhere with the included charging case. The charged case, with a 2,200 mAh battery, can recharge the in-ear headphones up to 15 times and also has a USB port to charge your iPhone if it ever needs power. The charging case also comes with four different silicone tips for the earbuds to ensure a perfect fit for every ear.
