1.  Why are the Purebuds earphones so innovative?
In the past 25 years, so much progress has been achieved in designing and arranging audio speaker systems like Dolby surround sound, DTS 5.1 channel, and home theater. But very few changes have been made in the acoustic field of earphones and headphones.

The Purebuds bring forth new innovations in the acoustic field utilizing “REVERSE SOUND” technology that leads to a unique & safer way to enjoy audio. Additionally, the Purebuds deliver innovation in the listening environments via the different audio tips included that allow you to customize your music with unique effects for bass boost, surround sound, or full range audio.

2. What is ‘REVERSE SOUND’ technology?
This is a new design of earphones that changes the traditional structure. It is a new invention in which the speaker unit is positioned opposite the side of the ear canal
 

This ‘REVERSE SOUND’ technology provides an outstanding natural surround effect and also significantly reduces ear discomfort when using these products as it does not fire sound directly at the ear canal.

3. How do the Purebuds deliver such pure music & safe sound?

When wearing the Purebuds earphones, the main body is arranged with the rubber ring (as an ear cushion) positioned in the ear canal, and the speaker unit facing opposite to the ear. The main body is then designed with the acoustic chambers to allow the reverse sound waves from the rear end of the earphone to flow back into the ear canal and then mix with the sound wave from the rear end of the speaker.

This outside audio flow has a physical delay in relation to the audio flow from the rear end of the speaker thereby creating a pure music effect & safer listening experience.
Benefits:

• No direct impact to the eardrum to reduce potential injury of the middle ear
• Allows users to hear background sounds and environment ambiance for convenience and enhances awareness of surroundings to help prevent accidents

4. How do the Purebuds deliver an entertainment value in the listening experience?

The Purebuds offers three different audio effect tips that provide different sound features like surround sound, full range, and bass boost.

5. Why is one cord of the Purebuds headphone cord design longer then the other?

The Purebuds Earphones deliver a unique asymmetrical cord design to help provide a more practical & comfortable experience with the headphone wires.

How does it work?

The longer cord wraps around the back of the neck to your other ear and the shorter cord goes directly into the other ear. You put the right cord around your neck. With one cable longer than the other both cords come together off center, to the side of the neck, or close to one ear. This design keeps the cord to the side and out of the way. See diagram here:

Benefits

• When you take the earphones out of your ears they hang around your neck instead of dropping to the floor.

• Design provides a cleaner and more comfortable fit

• Form factor reduces the frictional noise from all the wires moving against your clothing.

• With this asymmetrical cord design if the Purebuds fall off, they won't fall straight to the ground as your neck is supporting it.

• This design makes it clearer to identify which earbud is left & right.

Testimonial:

“…I like the cord style, with one side longer than the other. With my iPod buds I always had a problem wearing my shuffle in my pocket. The even cord always caused one side or another to get dislodged. The uneven cord is great, I can stick the one side around the back of my head and keep my shuffle in the opposing pocket. In addition I don't have to worry about getting tangled in the cord in the front when I am running….”
