The result is a pure balanced sound that covers the whole spectrum of human hearing. 2 dynamic drivers are used for bass and low-medium frequencies for a rich bass reproduction. The balanced armature drivers provide precise high and smooth hi-mid frequencies.
They come complete with a storage case, 3 memory foam buds, and 2 rubber buds. The quality of these monitors defy their price point and they represent an unbeatable, cost-effective way of experiencing the delights of in-ear monitoring
