FIIO FH7S in-Ear Earphones High-Performance 1DD+4BA Hybrid Technology IEM Earbuds with 3.5/4.4mm Plug

[Hybrid IEM's, 4BA+1DD]: FiiO’s new hybrid IEMs, the FH7S earphone 1 dynamic 4 BA driver design features a 2nd generation 13.6mm DLC diaphragm dynamic bass driver fully capable of extending to the lowest frequencies with ample punch. Mid and high frequencies are handled by a custom 4 Knowles BA setup that accurately reproduces every last musical detail. Together, these drivers provide a rich and detailed musical soundscape. [Sci-Fi armor design]: The FH7S features a design resembling that of armor seen in sci-fi, futuristic weaponry and machinery. the FH7S still retains an overall rounded shape that perfectly fits the human ear for comfortable extended listening sessions. [2nd-gen semi-open design]: The result is that when the drivers push air when making sound, that air encounters less resistance - resulting in a smoother yet detailed sound, natural timbre, large soundstage, and pinpoint accurate imaging. [Patented S.TURBO acoustic design]: The FiiO FH7S features the patented S.TURBO acoustic design*, which allows for deep bass that maintains plenty of nuance and texture. Sound waves are carefully guided through a turbine-shaped tube to enhance bass frequencies so that sounds like the beating of drums are appropriately thunderous and bold. [Debuting the all-new FiiO HS18 silicone ear tips 0.4mm]: new ear tips feature a large opening, same as the size of the FH7S sound tube, to minimize sound barriers between the earphone and the eardrum - which reduces high frequency loss and further enhances resolution.
