The Philips SHE2550 Extra Bass Earphones really do provide extra bass because most of the earphone design features contribute to the bass performance from the neodymium magnets and 15mm speaker drivers to the twin vents and ergonomic ear cushions.

The special shape and materials used for the SHE2550 earphone ear cushions ensure a perfect fit for maximum comfort and also prevent audio leakage, as well as enhance bass performance. And the ear cushions are shaped in such a way that they perfectly align with the area around a person's ear for long-lasting comfort.

The twin vents deliver a more balanced and natural sound - giving you extra bass and further enjoyment from your music on the go or at home.

As for the other technical features, the neodymium magnets produce a strong magnetic field for greater sensitivity in a voice coil, better bass response and higher overall sound quality. While the 15mm speaker drivers are small enough for optimum wearing comfort and big enough to deliver crisp, non-distorted sound.

The Flexi-Grip feature of the earphones means that the main cable connection is protected against damage from bending or whatever else you put your cable through.
