The basis for InEar universal housing designs was created by digitally "overlaying" hundreds of different ear molds. At the end of the development process, the result was an InEar universal monitor that is almost perfectly adapted to the anatomy of the ear.
Each of InEar earphone models has an individual sound signature. In the field of in-ear monitoring, InEar company motto is "By musicians for musicians". Because especially when it comes to the development of new in-ear monitoring systems or further developments, they can, apart from the conventional laboratory tests, also immediately test all new products in live use.
Incredible low bass and precise highs make the SD4 your choice for studio recording and live playing. Fine sound details never noticed with other earphones will be audible. For first-class listening experience. Whether singer or instrumentalist, this monitor will make everyone happy.
