Dr. Dre adds more Beats to Monster headphone range

Now he's expanding the range with the introduction of a smaller pair of in-ear 'phones, the snappily named Beats by Dr. Dre Tour, due to go on sale next spring for £119.95.

According to Monster, the Beats Tour offer the same enhanced audio clarity and deep bass punch as the bigger model, but in a more compact ear-bud style headphone.

They incorporate in-ear noise isolation and come with five custom-fit ear-tip sizes for extra comfort, and a compact carrying case.
