Enjoy the quality sound delivered from Philips Bubbles of Fun In-Ear Headphones. Each 13.5mm speaker driver is equipped with a neodymium magnet to create greater sensitivity, better bass response and higher overall sound quality--delivering your music with a crisp, non-distorted sound. These earphones have specially designed twin vents that channel the air balance, providing equilibrium between high tones and bass for a more rounded listening experience. Their shape is designed to perfectly align with your ear, and the soft rubber caps provide a comfortable fit. The specially designed shape seals in the sound, preventing it from escaping between the cracks separating your ears and the earphones. Bubbles of Fun earphones are durable, with a flexi-grip design that protects the cable connections from damage that can occur from repeated bending. These earphones can be used in a variety of different settings, including working out at the gym, commuting on public transportation or while relaxing at home. The green color is a fun accent that adds variety to any run-of-the-mill audio player. These earphones come with a music sharing adapter, giving you and a friend the ability to listen to the same music at the same time. A cord keeper is also included to help keep your cord tangle-free while being stored.
