Upgrade your listening experience

Add the optional CIPHER Lightning cable to connect your iSINE LX to your iPhone via the Lightning port. It takes digital audio directly from your iPhone and uses an integral DAC and amplifier to deliver enhanced voice call quality and superior audio. The built-in microphone can be used for both phone calls and Siri voice control, while the inset buttons provide volume and media playback controls.

Audeze's award-winning technology

Miniaturizing Planar drivers is no small feat. The new iSINE Series barely weighs 20 grams, contains all our exclusive patented technologies including power enhancing Fluxor™ Magnets and ultra-thin diaphragms with patented Uniforce™ voice-coil technology.

Our innovative planar magnetic drivers use NASA material to provide lower distortion, better bass response, and a wider soundstage than any other in-ear headphone. With their semi-open back design, the iSINE produces a spacious and authentic sound that will give you the sensation of experiencing a live, in-studio performance.

Listen Responsibly 

To avoid damage to your headphones and/or hearing, ensure the volume on your player is turned down before connecting your headphones. After placing headphones on your head, gradually turn up the volume until you reach a comfortable listening level. Exposure to excessive sound levels can cause gradual hearing loss and damage your headphones.

Excessive power levels can damage your headphones. Be sure to stay within the rated power level of 500mW RMS to minimize the risk of damage, which is not covered under warranty.
