Sony MDR-XB21EX Extra Bass In-Ear Earphone - Black

The MDR-XB21EX Extra Bass In-Ear Stereo Headphones from Sony provide high-quality sound with an extra kick that's perfect for hip hop and other bass-heavy music. The headphones use 9mm PET dome-type CCAW drivers with neodymium magnets to produce bass frequencies as low as 5Hz, and treble as high as 23kHz, ensuring that you don't miss any details in your music. The Direct Vibe Structure and angled housings provide an acoustically-tight seal for excellent sound isolation, deep bass, and a stable fit.

The soft hybrid silicone eartips come in 4 different sizes, allowing you to find the perfect fit. A proper fit not only provides the best comfort and stability, but also the highest level of noise isolation. The flat cable helps to minimize tangles, and the gold-plated L-shaped 3.5mm plug is compatible with a wide variety of electronic devices. A clothing clip and carrying pouch are also included.
