Manufacturers design MP3 players for mobility, but users are still tethered in another way. Most players have an audio port that is compatible with earbuds and headphones. The cords on these hearing devices vary in length, which is a convenience or a hindrance to the users. Also, the cord can eventually suffer wear and tear, becoming unusable. Bluetooth is a technology that is adaptable to MP3 players, and this can offer greater wireless mobility. Though the player does not include any of the components of Bluetooth connectivity, you can adapt the device so that it can transmit wireless audio.
Obtain a Bluetooth transmitter adapter for MP3 players. These are sold at local and online retailers. Some adapters are universal and connect to a standard 3.5mm audio port found on many MP3 players. Other adapters are constructed specifically for iPod devices. Navigate to the Web pages in the Resources section to see examples of brands, models and specifications.
