The Phiaton PS20 in-ear headphones most commanding feature is their advanced earpiece ergonomics designed for an extra-comfortable wearing experience, along with highly sophisticated sound and fashion-friendly looks. The PS20 dual chamber construction has an optimized open port air flow system maximizing clean acoustic efficiency -- which also allows for a more natural soundstage perspective versus the closed or 'boxy' imaging often heard with other in-ear headphones. Phiaton's proprietary 'MaxBass Reflex' micro-speaker armatures are engineered by audio scientists to present crisp, potent bass and well-defined highs with a vast 15 Hz ~ 22,0000HZ frequency response for excellent musical performance at an achievable cost. Highly recommended both for newcomers to in-ears and experienced listeners who may not want the immersively deep fit of some in-ear monitor designs.

The Phiaton PS20 earphones come with 4 sizes of soft silicon eartips provided in the box; try them all for best sound quality and wearing comfort. Luxurious glossy finish and gold wire rim accents provide a nice touch of upscale style and classy looks typical of Phiaton's beauteous Primal Series [PS] headphones. Beefy yet sleek wire strain reliefs under each of the earpieces provide great cord durability and a natural place to grip for easy removal & insertion of the earphones. Cord extends approximately 4.5ft and terminates to a straight stereo 'mini' 1/8" [3.5mm] plug. Good stuff all around, great job Akio and Phiaton team!
