Internal and external magnetic circuits
The JD7 features a 10mm dynamic driver with an international and external magnetic circuit setup that greatly improves the magnetic flux density so that the driver can push more air for a more effortless sound. The JD7’s driver is put into a dual-layer housing where each layer features a damping system to better control unwanted vibration and resonances resulting in lower distortion – ultimately resulting in a quicker-sounding driver with deeper bass.
More push for better sound
With the JD7 you can get great sound almost out of any source. Its magnetic conductivity enhancer increases the magnetic flux generated by the drivers to over 1 Tesla, resulting is a sensitivity of 108dB – meaning even your phone can easily drive the JD7.
God materials give you good sound
The JD7 features a polymer diaphragm with a PU gasket, specifically chosen for its unique and favourable characteristics. The PU gives vocals a unique, lush sound. The polymer diaphragm is stiff enough so that there is minimal unwanted vibration and movement during large driver moments, yet is still responsive enough to quickly move according to analogue signals as they come. All of this results in a fast, clean sound – especially in the bass.
The JD7 ear units are made of 316L stainless steel. The shells are made of metal powder that goes through injection moulding and is sintered at 1000 degrees in a process called metal injection moulding. This results in the JD7 not only being comfortable to wear but also being highly durable and resistant to wear and tear.
FiiOs new HS18 ear tips included
Included with the JD7 are three pairs* of FiiO’s brand-new ultra-thin HS18 ear tips. With a thickness of only 0.4mm, the HS18 eartips are light and comfortable to wear. The HS18 ear tips also feature a large opening the same size as the JD7 sound tubes to minimize sound barriers between the earphone and the eardrum, to fully let you hear the JD7’s sound as intended.
*S/M/L sizes included, size M is pre-installed.
The semi-open design of the JD7 has sonic benefits by allowing for a softer yet more natural sound in a wider soundstage. On top of that, the semi-open design balances air pressure in the JD7’s housing which eliminates pressure on the eardrum and ultimately protects your ears, for long fatigue-free listening.
The JD7 comes with the HB1 storage case that not only allows you to conveniently organize and carry your earphones with you on your travels but also securely protects them too.
