Styled in navy and gold finish, these Shadow Wireless Earphones by Sol Republic are able to receive audio via Bluetooth between multiple sound sources, allowing you to switch between two such Bluetooth-enabled devices. It does so while providing a pleasurable sonic experience, particularly in the bass and high-end frequency bands. With these earphones, you can also answer/end phone calls—and play and pause music—directly from the biomorphic neckband, which has been designed to ensure a comfortable fit. What's more, the battery on these earphones can last up to eight hours after a single charge. Included with the earphones are four sets of various-sized eartips and a USB charging cable.
