The STAX SR-407 Signature Open Back Headphones feature a New Sound Element, Low-Capacitance Wide Cable, Rich, Deep Low-Frequency and Delicate High-Frequency Sound!

Introducing the STAX SR-407 Signature Open Back Headphones! STAX's first SR-A (Lambda) series Headphones were introducted over 30 years ago, and now the SR-407s have accomplished further evolution with a New Sound Element! The original Sound Element had employed the simplest of structures so that the widest film diaphragm area as possible could be effectively used in comparison with its external size. Taking advantage of the this original feature, the New Sound Element has been packaged in a tough resin case, thus has realized Cleaner Sound and a More Accurate Sound Image. Also a new thin-film material, practically stretch-free through temperature and humidity, has been adopted, enabling both the Rich, Deep Low-Frequency and Delicate High-Frequency Sound.

The SR-407 employs a New Sound Element which is encased in a tougher resin to minimize vibration.
