A motorcycle helmet audio device of any sort is a great asset for a motorcycle ride, especially a long distance trip.  The type of helmet which the rider wears will make a great difference in whether the headphones will fit comfortably in his ears or not.  The device itself, as well as its location in the helmet, has the greatest effect on the volume of the headphone speakers.

Good headphone speakers are smart and thin headphones built into the motorcycle helmet.  They have a reasonably high volume, and are designed to fit comfortably inside your helmet.  They can plug into radio, mp3, or CD players because they have a basic 1/8-inch output jack.  If they are made well, they will fit cozily inside the helmet and your ears, so that they will neither fall out nor pinch your ears.

Even if it is a little more expensive, you will want to purchase a quality set of helmet speakers for your own comfort, enjoyment and safety as you ride.  Certain devices have integrated speaker and microphone hardware that will allow you to access the radio, telephone and intercom systems when you are riding with a partner.  Another great asset is an audio GPS navigation system, which is most easily used with helmet speakers.  These are just a few of the great possibilities available in headphones for motorcycle helmets.
