The Beyerdynamic DT 235 Dynamic Closed-Back Supra-Aural Headphones provide high-quality sound with a wide frequency response in a lightweight package. Ideal for use with portable music player or home HiFi systems, the DT 235 uses powerful acoustic drivers to provide clear, detailed audio with deep bass and clear treble. These features make the headphones a perfect companion for everything, from listening to classical music to lifelike movie sound effects. What's more, the headphones have velour ear cushions and a wide self-adjusting headband to provide hours of listening comfort. The closed-back design helps to naturally block out environmental noise as well as prevent sound leakage so you don't disturb others around you.
