The MDR-XB300 extra bass headphones from Sony are designed to create incredible bass levels within the confines of a traditional headphone. The headphones use 30mm dome drivers to produce an extra-wide frequency response with bass levels down to 5Hz. The direct vibe structure ensures a high level of audio fidelity, while the sealed acoustic design provides a high level of noise isolation.
The headphones feature a comfortable adjustable headband and ultra-thick king-sized ear cushions. At over 1" thick, the cushions provide long-lasting comfort and exceptional acoustic performance. The flat Y-type cable keeps tangles to a minimum, and the gold-plated 3.5mm mini plug provides compatibility with MP3 players, CD players, computers, and more.
