Celsus Sound Launches Gramo One, a Reference-Grade Open-Back In-Ear Headphone
The Celsus Gramo One is a reference-grade open-back in-ear headphone that sits comfortably on the outer ear. With the portability of an IEM, the Celsus Gramo One’s exceptional sound quality equals or betters the most highly regarded over-ear headphones. It is designed for long listening without the drawback of the weight of over-ear headphones or ear pressure of in-ear earphones.
Celsus Sound today announces the release of the Celsus Gramo One, a reference-grade open-back in-ear headphone specifically designed for quiet listening environments. Sitting comfortably on the outer ear and with the portability of an IEM, the Celsus Gramo One’s sound equals or betters that of the most highly regarded over-ear headphones.
One’s first – and enduring – impression is of an overwhelming, three-dimensional audio experience that can fairly be described as a virtual live event. The proprietary 16mm Celsus sound transducer produces a sense of space, depth, detail and dynamic range as impressive as that of an audiophile’s dream sound system. A mesmerizing midrange and solid bass are among the more impressive of the Celsus Gramo One’s signature qualities. It has a seductive vocal textures rarely found in high-end earphones.
The term reference-grade typically connects with a few widely celebrated over-ear and on-ear headphones. Their common drawback – and it’s a serious one – is weight and size as principal contributors to listener fatigue. In recent years, a few in-ear headphones have achieved reference-class status. Again, as a drawback, IEM devices suffer from an ultimately fatiguing music-in-the-middle-of-one’s-head effect along with the excessive ear pressure that inevitably accompanies prolonged listening. The Gramo One, a different animal entirely, avoids these pitfalls through creative engineering.
