Description
The compact yet powerful mobile headphones "PHONON 4400" are back with an even easier-to-use design. Compared to the previous PHONON 4400, they are especially durable.
These foldable and compact headphones are ideal for playback on mobile devices such as smartphones and for monitoring while DJing.
The PHONON 4400's incredible performance comes from its powerful sound, which is hard to imagine considering its size. It is lightweight to eliminate the inconvenience of carrying it around and discomfort caused by wearing it for long periods of time, yet it delivers clear, powerful bass without any muddiness.
Furthermore, the PHONON 4400 is infused with a wealth of PHONON's unique tuning know-how. This tuning method is original, and actively incorporates approaches that major manufacturers would never take. The flat, high-resolution sound quality without any unnecessary coloration has an overwhelming sense of balance, and has earned high praise from DJs and engineers around the world.
The PHONON 4400 mobile headphones are still loved by many people, including top DJs around the world.
Please take a look at the NEW PHONON 4400, which has been carefully crafted based on the concept of "easy portability of the sound quality we pursue."
