Amazing Klipsch® sound you can take with you everywhere

Take reference sound on the go with the Klipsch Reference S4i headphones. These portable in-ears take advantage of Klipsch's decades of audio know-how to deliver your tunes with impressive realism, clarity, and bass response. Klipsch also designed the Reference S4i in conjunction with Apple® to provide easy control of the music loaded on your iPhone®, iPod®, or iPad®.


Switch between your calls and music with ease

imageone_remote A three-button remote control built into the headphone cable lets you conveniently answer and end calls, control the volume of your calls or music, and pause, play, or skip through your songs. You can even take calls on your iPhone hands-free, thanks to an in-line microphone. The mic features echo cancellation that keeps your voice clear so you won't have to worry about surrounding noises drowning you out.

Hands-on or hands-off, you control the show

The Reference S4i makes controlling your player and your music a snap. The plus and minus buttons let you adjust the volume up and down, while the middle button handles the rest. When listening to music, press the middle button once to play or pause your tunes, twice to skip forward a track and three times to skip back. For phone use, press the middle button once to answer and once to end the call. You can also use the middle button to take advantage of the voice control feature on the latest iPhone, iPad, and iPod touch models. Just hold down the button and say your command.

Comfort, good looks, and convenience

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 stylish gloss black finish with copper accents for a handsome 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 S4i include a handy case for storage and travel.

Features

Reference Sound: The Reference S4i 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 S4i features angled housings for proper in-ear alignment. The Klipsch Reference S4i'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 S4i comes with four different sizes of washable ear-tips;  small, medium, and large single-flange ear-tips, plus pair of dual-flange ear-tips.

3-Button Mic and Remote System: Thanks to its advanced 3-button mic and remote system,  the Reference S4i offers control of your Apple iPod, iPhone, or iPad. The built-in 3-button remote control lets you answer and end calls, turn the volume up and down, and control music playback (Play/Pause, Fast Forward/Rewind, Previous/Skip). Unlike other headsets, the S4i positions its mic and remote at the cable yoke to create a more natural feel when answering calls and controlling music. The mic is a highly intelligible 360° design with echo cancellation, so you will be heard crystal clear and will not have to worry about the external noise around you. The Klipsch Reference S4i is compatible with the following Apple iPod, iPhone, and iPad models (as of 8/14/2012).

Good sound, comfortable, smart

  • "Coolness Factor"

  • Sound Quality

Sounds great and is very comfortable. Not much sound reduction, but that's good since I use them on my daily fitness walks and need to hear what's going on around me. The iPhone/iPad controls work as advertised and the cords are better than most and should resist damage. Wish a bit more in the way of instructions came with the things, though; there's lots more about the features of these headphones in the advertising copy than the official manual.

Pros: Good sound, great looks, and comfort, high quality components and construction, as would be expected from Klipsch

Cons: Minimal documentation
