However, the portability of headphones is usually limited to the portability of the device that is used to provide the music. For instance, if you want to listen to music while moving from one room to another, headphones might not provide the desired mobility. This limitation led to the introduction of wireless headphones. Lastly, the wireless headphones you choose should be offered with a warranty to protect you against unintended damages. SkullCandy wireless headphones provide all these characteristics. For example, earbuds, which are small in size, are meant to be placed outside the ear canal, while canal phones, which are smaller, should be inserted directly into the ear canal. SkullCandy produces headphones to fit all these categories. For instance, the SkullCandy skullcrusher, LowRider, and Double Agent fit in the over-the-head category. SkullCandy Smokin buds and SkullCandy ink’d fit the in-ear category. These in-ear headphones are often bundled with iPods and other MP3 players and can simply be placed in a pocket. Another type of headphones, which are larger than in-ear headphones, sit on the ear and include an elastic frame which either sits on the head or wraps around the neck. One option to consider are Bluetooth headphones. Bluetooth headphones are a type of wireless headphones which are designed for Bluetooth-enabled products. Such products include cell phones. Despite the fact that they were built with a headband which was intended to alleviate the weight of these earphones, they were nevertheless heavy and uncomfortable, because these very first devices were large enough to cover the entire outer ear.
