Powerful Sound with Utmost Delicacy 
The rationale is the development of the new SR-007MK2 Earspeaker was to provide deep powerful sound previously unobtainable in Earspeakers. STAX engineers developed a unique new electrode structure. Visible through the outer case, gold plated on the outer edge this new electrode has less holes than conventional STAX Earspeakers and thus provides an increases diaphragm vibration area allowing for rich and powerful sound yet retaining all the delicacy STAX is famous for. 

Rigid Metal Housing 
To maintain clear distortion free sound it is most important that nothing other than the diaphragm should vibrate. Within the STAX SR-007MK2 the sound element is encased in a thick insulated resin case firmly fixed to the rigid body. The results are nothing short of spectacular. 

Fully Adjustable Earpads 
Utmost comfort for maximum enjoyment of your STAX SR-007MK2 is provided with earpads that are fully adjustable to the shape of your head.
