Empower Your Ears

The GeM-1 earphone system is a radical rethink of modern earphones and headphones. For too long, the industry as a whole has been enthralled with sound isolation as the solution to all our audio needs. And though sound isolation has its place, it doesn't address the reality that our audio technology has become truly mobile.

In fact our audio solutions and communication methods have become more and more integrated into our everyday activities. It quite simply goes where we go. Single purpose isolating earphones may be fine when relaxing on a plane or alone at home, but for the rest of the time they don't really meet our needs. Self-preservation is a very real human instinct, and being disconnected from one’s surroundings often feels uncomfortable and unsafe.

GeM-1 earphones, working with AMBi APPS, address this issue. They provide audio quality equal to or better than any high quality earphones on the market, and layer in ambient sound of equal quality, all done at the levels you select. You control the balance between your audio and ambient sound levels, enabling you to best control the sounds you hear, no matter the situation.

We call it "Audio in Concert" because it's very much like being at a concert where you are the mixer who independently controls the volume level of the crowd and the band. Empower Your Ears, and enjoy your audio in your activities! 

Set up primarily for the Urban Guerrilla in all of us, the ROX version of GeM-1 Balanced is ready to work for and with you through most any of life’s everyday activities. From working out at the gym, toiling at the office, commuting, cleaning house, making dinner, attending to kids, to just hanging out at home or with friends on the ski slope. You can now do it all, possibly even better, and not miss a beat in your music or your activity!

GeM-1 Features

The GeM-1 earphone system was designed from the ground up to meet the needs of today’s mobile technology and the fast moving society behind it. The features of GeM-1 system were designed with years of frustration in mind, seeking to remove some of the pet peeves and common annoyances that people deal with everyday. While it would be ideal if no compromises were made, nothing is perfect. But we're confident that the GeM-1 system will set a new standard for amazing earphones.

In short, the GeM-1 earphones provie excellence in audio quality, comfort, appearance, and of course, ambient awareness.


Dual Omnidirectional Mics

GeM-1 earphones are the first and only units designed from the get-go to work with Smartphone apps, specifically AMBi, in order to produce high performance ambient hearing capability.

The use of dual omnidirectional mics provides maximum ambient sound coverage and spatial perception. The type of condenser mics used are excellent at reproducing clear, natural sound, from very low on up to very high ambient sound levels. These same mics also provide excellent mobile phone communication. Staying connected to both your digital realm and real world has never been so natural.


Respect Ear Canal’s Geometry

The proprietary geometry developed by GRiT positions the axis of the eartips directly in line with the natural axis of your ear canal. This natural fit is readily apparent the first time you put them on. Total comfort!

Our design works with the natural shape of the ear canal to locate the eartips so that they are doing only one job, sealing. Removal of the eartips, while not recommended, does not significantly hinder the GeM-1’s ability to remain stable and securely in position in your ears.  Try that with any other non-custom earphone.


APPs That Make “Ambient Sense”

AMBi APPS are the purpose-built applications that make GeM-1 shine as the benchmark for all ambient awareness earphones. From connecting with your surroundings to listening to high quality audio, AMBi is the final piece of the puzzle for our modern life. It frees you to go and do what you want without having to choose between a connection to your real and digital worlds.

AMBi APPS make it possible to combine the two as you see fit, creating the balance you need. Life’s sounds are all around, so why not make it all “Audio in Concert”. (See AMBi APP page for details and compatibility for your Smartphone, Tablet or Media Player)


Micro-Tip Dual-Seal Eartips

The proprietary geometry positions the eartips within the ear canal where the smaller-than-usual hypoallergenic silicone tips seal gently against the walls of the ear canal. Since the tips do not serve to retain the earbud in the ear, considerably less pressure is required.

This translates into far better comfort, no matter how long you wear them. The seal serves to maximize audio quality, reduce excessive ambient sound levels, and allows for lower volume settings... all kind to your ears.


Balanced Armature Drivers

The advent of the modern digital media player, which feature sophisticated and powerful equalizers, has allowed our next generation “moving armature” type balanced armature drivers to perform at a level that can only be described as “life-like”.

You will hear instruments and detail in your old (and new) songs that you never knew were there. This incredible clarity is augmented by tone control and power across the entire sound spectrum. From crystal clear highs to heart pounding bass, you will rediscover your audio all over again.


Respect Outer Ear Geometry

The cone and hoop sections of the earbud are designed to conform to the natural shape of the outer ear. The slanted cone section fits perfectly within the tragus (that little flap in front of ear canal) positioning the driver as close to the ear canal as possible for best audio quality. Even the strain relief and cable exit the earbud at a compound angle to make sure that it fits better than any other earbud you've ever tried.


Dedicated L & R Earbuds

Most earbuds are physically identical from left to right, other than a small label to indicate left and right. The GeM-1 earbuds go way beyond that with dedicated left and right assemblies.

We could have compromised on the design but then they wouldn't be comfortable and wouldn't perform well. This is yet another example of the refinement you'll find throughout the product. And no need for a magnifying glass to read he little “L” or “R”.


Stability, Security, & Ease

The overall geometry results in an earbud that is inherently stable and secure in the ear without any need for clips, wedges, clamps, or oversized eartips that often cause pressure points and discomfort.

At the same time, inserting and removing them is simple and intuitive. The GeM-1 locates itself in the ear, the same way, every time, and cannot be over-inserted. Additionally, the flush design allows use under hats and helmets, remaining comfortable and secure even if external force is applied to the ear and earbud.


Wired Connectivity

Sometimes conforming to the status quo is a good thing, and in the case of connecting to all the myriad of media devices on the market, there is a solid standard that is the 3.5mm Audio Plug.

This 4-connector plug will allow your GeM-1 earphones to connect to just about any media player for audio, most Mobile phones for communication and audio, and most smartphones for audio, communication, and ambient awareness.
