It was just a matter of time for Sennheiser's innovative and market-leading brand of over-ear headphones, the Sennheiser Momentum, to make the jump to the portable and commuter-friendly in-ear variety. Normally one would say that the family-owned German brand was just trying to match Dr Dre's Beats jab-for-jab, but the decision was just part of the normal evolution for Sennheiser, who have been winning rave reviews for their work long before the Dre even dreamed of entering the business. Priced at $99, there are versions for both Android or Windows smartphones set to launch this month along with an Apple iOS-supported version coming later this year. Inside the powerful bean-sized buds, Sennheiser has packed in newly developed transducer technology, stainless steel acoustic pipes, and a dynamic speaker system that can handle powerful bass and crisp trebles. Outside, the casing is just as beautiful as the sound, with a slick two-tone cable in several colorways that have the added bonus of avoiding tangles.
