Enjoy quality sound and a comfortable fit from Philips SHE9800 In-Ear Headphones. The 15-degree tilt acoustic design adjusts the angle of the speaker tube and ear bud to individual ear canal shapes. It creates a functional seal from ambient noise that enables you to listen to your music at a lower volume. The sound stage enhancer design modifies the conventional headphone structure to complement the powerful microdrivers in producing a wider sound stage effect. These microdrivers are specifically designed to produce extra deep bass and wider dynamic range to unleash the full potential of your audio device. These headphones are made with Philips iLab technology to ensure greater output from lower frequencies to help create a more balanced and crisp sound. The headphone's body is made of soft flexi-grip material that protects the cable connection from damage that occurs from repeated bending of the headphone body. Three different sized soft silicon caps (small, medium and large) match your individual ear size, giving you an ultra-comfortable customized listening experience. The durable carrying pouch with cable bank provides an easy solution for neat cable winding and headphone storage.
