Comfort, good looks, and convenience

The Reference S4s feature angled housings for proper in-ear alignment that reduces strain on your ears. Klipsch's patented oval ear tips fit the natural shape of your ear canals better that standard round ones for hours of listening comfort. These ear tips also create a tight seal to help minimize outside noise and enhance bass, so you can enjoy your music at lower, safer volumes. And since the noise reduction is passive, no batteries or active electronics are ever needed.

These 'phones feature a handsome gloss black finish with copper accents for a stylish look. The durable, tangle-resistant cable prevents snarls while the supplied clothing clip helps keep it in place when you're on the move. And the Reference S4s include a handy case for storage and travel.

Features

Reference Sound: The Reference S4 in-ear headphones deliver realistic sound  through the use of a single, moving coil micro-driver (or mini-speaker) per channel. These drivers cover a wide frequency range (10Hz-19kHz) with dynamic detail and deep bass.

Noise Isolating Ear-Tips: The Reference S4 features angled housings for proper in-ear alignment. The Klipsch Reference S4's exclusive soft and flexible oval ear-tips naturally fit the contours of your ear canals, providing comfortable long-term wear as well as producing a perfect acoustic seal. A good seal minimizes outside noise, also known as noise isolation (up to -16), and allows you to enjoy your music at lower, safer volumes. The Reference S4 comes with four different sizes of washable ear-tips;  small, medium, and large single-flange ear-tips, plus pair of dual-flange ear-tips.

51" Headphone Cable: The Reference S4 in-ear headphones feature a durable 51" headphone cable with built-in strain relief.

Gold-Plated Connector: The Klipsch in-ear headphones feature a gold-plated, male 3.5mm connector, so it works with any portable device that features a standard 3.5mm headphone output.

Carrying Case: The Reference S4 comes with an aluminum carrying case to store the headphones when not in use.
