Designed to satisfy even the most demanding musicians, the GR In-Ear monitors are comfortable, lightweight, and powerful. We have paid special attention to the low frequencies, which are always the most difficult to handle. The GR Bass In-Ear monitors are not just for bass players. Two models in the universal series are compatible with custom models, which offer personalization in terms of shape, number and type of drivers, and response. The full range includes two In-Ear monitor models with different drivers.
