Let nothing come between you and your music when you have the Sennheiser IE 900 audiophile headphones. These audiophile headphones have the new X3R technology. It’s a team of three Helmholtz resonators that eliminate resonance peaks that can alter the feel of your music. They’re milled right into each earphone’s aluminum case. There’s also Sennheiser’s 7 mm TrueResponse transducers for a sound that’s true to life. Moreover, an XWB driver ensures natural-sounding audio thanks to the high-quality materials in the diaphragm. Furthermore, the Sennheiser IE 900 offers a precise fit with its silicone ear adapters and three elastic foam ear adapter sets in 3 different sizes. What’s more, the acoustic back-volume controls the amplitude of the base lift. This helps you get a clear, pure sound. Finally, gold-plated Fidelity+ MMCX connectors are durable and give you perfect contact. With the Sennheiser IE 900 audiophile headphones, the music is always amazing.
