  • RigidBody™ steel alloy construction delivers deep, clean bass.

  • Custom silicone carrying case with cable management.
Designed for discerning ears that crave for satisfying bass with extraordinary detail, Vortex™ reference in-ear headphones feature Moshi Audio's roprietary RigidBody™ driver housing aimed to deliver fast articulate bass without distortion. The drive units consist of high-definition Neodymium drivers housed in sintered steel alloy which minimize cavity-induced coloration. This design not only vastly improves low frequency extension, but also renders silky smooth highs.

To obtain meaningful bass from any in-ear headphones, a tight seal between the ear tip and your ear canal must be achieved and maintained. Most in-ear headphones' cables are much heavier than the individual driver unit, this constant weight-drag causes the drivers to fall out of your ears' secure sealed position after awhile. Vortex's lighter cable/heavier driver weight distribution enables the drivers to fit securely in your ears even when the cable is fully extended. To further ensure a secure yet comfortable fit, Vortex comes with 3 different sizes of hybrid-injection silicone ear tips as well as a set of memory-foam ear tips for optimal listening experience. It is also equipped with an iPhone compatible microphone for answering calls on the fly while listening to your favorite tunes.




Like breaking in a new pair of leather shoes, high-quality headphones perform better once they've been used over time. This process can take several weeks or even months, so Moshi Audio has developed a helpful iOS application to expedite the burn-in process. By playing back a curated list of tones/frequencies, the Moshi Audio Burn-In Tool allows the headphone diaphragms to relax and reach their optimal level of sonic performance. Simply install the burn-in tool on any iOS device and select the headphone and desired burn-in period. The burn-in tool is customized for all Moshi Audio headphones, but also includes support for any third-party audio headsets as well. 


Getting the best out of your earphones:

  • Ears come in different shapes and sizes, make sure to pick the most appropriate ear tips for your ears. Try out all of them to see which ones give y ou the best seal of your ear canal. A good fit guarantees good bass output.
  • To minimize microphonics effect, try wearing the earphones with cables going over your ears.
  • High fidelity earphones require properly encoded music. Compression with bit rates higher than 192k or lossless source files recommended for satisfactory auditioning experience.
WARNING
  • Keep the earphones away from fire, water, strong magnets and children.
  • Elevated listening volumes can cause permanent hearing damage, please reference the guideline below for recommended usage limit (OSHA Regulation 1910.95):
90 dbA 92 dbA 95 dbA 97 dbA 100 dbA 102 dbA 105 dbA 110 dbA 115 dbA
8 hrs 6 hrs 4 hrs 3 hrs 2 hrs 1.5 hrs 1 hr 0.5 hr <0.25 hr

Using the MIC button (for iPod / iPhone and certain smartphones):
  • During music playback, clicking the button once will pause playback, click again to resume.
  • Double click the button to skip forward to the next song (FF), triple click to go back to the previous song (REW).
  • For calls: click the button once to pick up the call. Click and hold the button for 2 seconds then release to decline the call.
  • Call waiting: click the button once to put the first call on hold and switch over to the second call. Click and hold the button 2 seconds then release to end the first call and pick up the second call.
Using the carrying case
  • To store the earphones, insert the earplugs into the left and right slots respectively, then wind the cables around the case as shown:
