Experience realistic audio with the Sennheiser CX 200 Street II, a pair of superbly made in-ear headphones. The finger-contoured housing design of these Sennheiser headphones makes it easy for you to adjust them and achieve a snug fit. A perfect air seal, courtesy of the in-ear design and ear adapters, helps the Sennheiser CX 200 Street II deliver the best music quality. These white Sennheiser headphones also cut out the ambient noise for clearer audio in noisy environments. What’s more, the gold-plated 3.5 mm jack does not corrode very easily, and ensures compatibility of these in-ear headphones with a wide range of products like MP3 players, cellphones, and other devices.
