The Sony MDR-EX40LP is a lower mid-cost set of in-ear headphones, available in a confection-inspired variety of colors that Sony calls Jienne Pop. In terms of headphone performance, this model is a step down from the higher cost MDR-EX50LP model in that it lacks the high-density acoustic resistor, which contributes to a deep bass tone. That being said, the 400 kJ/m3 high power neodymium magnets of the MDR-EX40LP headphones are powerful enough to offer a substantial bass. The PET diaphragm of these headphones ensures a minimum of distortion, even when the bass is cranked. To help ensure a stable and comfortable in-ear fit, these headphones are designed with an angled earbud structure. The included sets of hybrid silicone earbuds, which come in three sizes, help you to find the proper fit for your ears.
