The world first Coaxial two-way headphone design by an implementation of AMT tweeter and Dynamic Neodymium driver to deliver a rich sound stage listening experience in the headphone market.
The term "unique" often pops up in reference to new products, but the company believes these two-way coaxial headphones justify the tag, due to their fully patented AMT driver technology.
AMT stands for Air Motion Transformer - where the loudspeaker driver moves air using a folded diaphragm, built around a series of aluminium struts inside a "high-intensity" magnetic field.
Once the signal has passed through these struts, the diaphragm moves back and forth, (imagine an accordion's action), pumping air through the chambers.
This results in a dipole driver that oBravo claims to have an "extraordinarily rapid response rate", with the diaphragm covering less distance than a dynamic driver with a traditional cone.
oBravo also says that a standard 25mm AMT strip is comparable to a 20cm circular dynamic cone in terms of its functional driver area, with the aim of delivering a fully immersive experience.
The exterior of the HAMT-1s is built using a combination of aluminium, wood and leather.
Specification:
•Frequency Response: 15Hz~45KHz
•Tweeter: 40mm AMT Tweeter
•Sensibility in dB/1W/1m: 105dB
