When we naturally hear sound, we hear each individual component with both ears and use the relative differences of the loudness and timing in each ear to accurately identify and locate it.
But this doesn’t happen when we listen with headphones because, unlike when listening to loudspeakers, our left ear can’t hear what’s in the right channel and similarly our right ear can’t hear what’s in the left. Consequently, headphones defeat our natural way of determining the character and direction of each sound. The result varies from person to person but is typically the “inside the head” headphone sound where we correctly perceive the location only when it is directly in front of us. All other sounds are pushed left or right and often sound as if they are behind us or somewhere inside our head. Making the situation even worse, we perceive sounds from center front at close to half their correct loudness compared to all other sounds. Most of us have simply come to accept this from even the most expensive headphones because until now there hasn’t been a satisfactory solution.
Now, for the first time, iSpaSe completely fixes the problem and unlocks the full potential of all headphones allowing us to locate and interpret sounds correctly. We hear music as if we are at the concert, sports as if we are right there at the game and movies as if we are in the scene with the actors.
The key to iSpaSe headphone technology is a breakthrough in stereo to binaural sound conversion that combines the available left and right channel audio to create a precise replica of the actual sound that we should hear in each ear. With an iSpaSe SMK, we are able to accurately locate and focus sound in any direction to the left or right, up or down and front or back. With all the unique components of each sound located correctly, the quality, richness and clarity of the original is restored giving us an amazingly authentic listening experience. iSpaSe is also the world’s first technology to recreate the original three-dimensional surround sound experience from two channel stereo sound.
iSpaSe SMK
iSpaSe SMK is a small, lightweight and affordable battery powered unit that connects between headphones and media player using the standard stereo headphone output that is available on all players. The unit measures 2.6 x 1.6 x 0.8 inches (6.5 x 4 x 2 cm) and weighs 2 oz (57 grams) including batteries. It is powered by 2 AAA batteries with an expected battery life of over 100 hours of typical use and is simple to use requiring no adjustment or set-up. The only control is an on/off switch. iSpaSe SMK works with all headphones that have a standard 3.5 mm jack plug and is compatible with the microphone and remote control features in most mobile phones including iPhone 3G and later versions.

Use iSpaSe for Music, Movies and Games
iSpaSe is terrific for bands and orchestras, where it focuses individual vocals and instruments and places musicians at their correct location. For video games, it heightens the sense of reality by precisely locating each sound where the relevant action is on screen. For TV and movies. iSpaSe needs only the stereo from DVDs and streaming media sites to recreate the original movie surround sound and unlike when listening even to the very best loudspeakers, those helicopters really do fly over your head!
Use iSpaSe Anywhere
iSpaSe creates the natural sound that we normally hear, so that external noise isn’t as annoying. We no longer need to be cut off from our surroundings. It’s easy to adjust the media player volume to hear an acceptable mix of iSpaSe music and the sounds around us that we need to hear.
