Until now performers have had to choose between a dedicated in-ear monitor mix or an ambient experience. Now, you can hear and feel the energy and input from the audience, fellow performers and the stage—together with the incredible audio clarity, frequency response, and punch that only a Westone Audio In-Ear Musicians’ Monitor can provide. Traditional open vent ambient monitors compromise and degrade the frequency response of an in-ear monitor. With Westone Audio’s exclusive Ambient Patented Technology technology, you are in control of your musical environment. Enjoy full-range frequency response from your in-ear monitor signal, hear and feel your surroundings, and engage with fellow performers and your audience like never before.
