Brain-rattling Bass You Can Feel - FiR Audio Neon 4
Hearing the bass is one thing, actually feeling low-end sounds kick and slam on your ear is an entirely different thing.
With the FiR Audio Neon 4's Kinetic Bass technology, you can enjoy deep-reaching detailed bass and feel every bass note reverberate through your ears for a truly immersive listening experience.
The massive bass port at the back of the Neon 4's shell pumps low-end frequencies directly to your outer ear for a satisfyingly tactile bass feel. You won't experience bass like this on any other IEM.
Experience Enhanced Soundstage and Comfort with the Neon 4 ATOM Venting
IEMs work by moving air through drivers to produce sound. All that extra air will eventually fill your eardrums and cause in-ear discomfort.
Never worry about ear pressure ever again with the Neon 4. ATOM Venting technology allows extra air to exit through revolutionary ATOM Modules for enhanced comfort and soundstage.
The best part? You can swap out the ATOM Modules to get your preferred ear pressure release and noise isolation.
Authentic Unrestricted Sound with Open Acoustics - FiR Neon 4
The Neon 4 is designed to deliver only the purest sound possible to your ears with its Open Acoustics system comprised of Open Drivers, Sound Reactor, and Sound Reflector tech.
The Open Acoustics architecture features a fully tubeless design for the purest sound reproduction. Sound from the Open Drivers naturally flows toward the Sound Reactor chamber and is pushed out to your ears through the Neon 4's nozzles. The High OpenDriver located in the canal stem of the Neon 4 features its own Sound Reflector for ultra-smooth high frequencies.
