There are two types of waterproof headphones. The first connects directly to your phone, via Bluetooth, and therefore plays whatever your phone is playing. This has the downside of needing your phone to be as close as possible for uninterrupted sound.

Turn the Bluetooth ON, on your device. > Open the charging case and remove the Earphones, they will automatically turn on (or can be turned on manually). When the LED indicator on one side earphone flashes red and blue alternately, which the other side flashes blue, pair the earphones with your device.

Which looks good for earbuds black or white? Black, it goes with every color! White would stand out a lot according to me. But it still depends on your personal preference.
