Sennheiser HD 25 SP ii Description
The Sennheiser HD 25 SP ii are a lower-cost alternative
to the HD 25-1 II, featuring a simpler headband and a
slightly different capsule design, yet boast high
performance for critical listening, DJing and mixing.
A compact, closed back dynamic headphone, the HD 25 SP
offers high attenuation of background noise, features
robust construction, and is capable of handling very
high sound pressure levels, making it ideal for use in
noisy environments.

design, the Sennheiser HD 25 SP is for those
professionals who spend a great deal of time wearing
headphones and need maximum isolation. The headphone
ensures an accurate response for critical studio
recording and mix applications. The low impedance, high
sensitivity drivers exhibit a healthy level of
efficiency, providing sufficient volume even in
applications that would required an additional headphone
amplifier.
