Understanding the product specification
Sound pressure, Decibel and Hz
Sound is an invisible vibration composed of frequencies which travel in undulations known as sound waves. The amplitude of vibration produced by an object such as a speaker driver is proportional to the change of pressure generated as the wave moves through the medium which surrounds it (such as air). Therefore, the amplitude of a sound wave is commonly measured by its pressure level.
The decibel is a non-dimensional, logarithmic scale to denote a relative change in the strength of a signal or wave. When placed in the context of sound pressure level; it measures the nominal threshold of human hearing, relative to the quietest sound audible to the human ear.
The frequency of instances where a sound wave reaches it peak during a period of time is measured in Hz (hertz). This is the number of complete cycles per second. Human hearing is limited to frequencies between about 20 Hz and 20.000 Hz.
Sensitivity and impedance
Earphone sensitivity is measured in Sound Pressure Level (SPL). This is essentially a measurement of how loud or easily-driven a pair of earphones is.
The sensitivity is also influenced by the drivers' coil impedance which varies over the frequency range. The higher the SPL and the lower the impedance the more easily driven your earphones will be.
Precautions
- Do not use the product in other ways than are described in this manual.
- Handle with care at all times and protect from external damage.
- Do not expose to heat, magnetism or cold, damp environments.
To clean: use a mild, antiseptic detergent. - Do not expose the cables and plugs to abnormal wear and tear, e.g. by bending or pulling them.
- Avoid winding the cable too tightly.
- Avoid dropping or strong impact. Always leave the sleeve on for shock protection.
Proper use
The a-JAYS Four+earphone model is suitable for many different areas of use. It is particularly suited to environments where you are likely to be disturbed by ambient noise, e.g. at airplanes, on trains, on the subway, at the gym or when you are studying. In short, whenever you want. Let nothing come between you and the full enjoyment of your music.
Inserting and removing the earphones
- Turn the volume to minimum before insertion.
- For best results, moisten the ear tips before insertion.
- Holding the earphone at the rear, carefully insert the sleeve while pulling up and out on the back of the ear.
-
The microphone should seal deeply and comfortably in the ear canal.
-
If the bass frequency response seems too feeble or if external noise has not been eliminated, try inserting the earphone deeper into the ear canal to obtain a better seal or try a different sleeve size.
After use, remove carefully - avoid pulling the cable.
Three button remote
a-JAYS Four+ for iOS, Windows or Android houses a high-quality, 360-degree MEMS microphone for optimized speech quality. Built-in echo cancellation improves communication in nearly all situations and the remote housing is rubberized for better grip and ergonomics, making a-JAYS Four+ the perfect everyday partner for your smartphone.
Cleaning
Clean your earphones regularly using an antiseptic cloth or wipe. Keep ear tips free of wax and other build-up. Wax and dirt can adversely affect sound quality and can damage your earphones. Furthermore, ensure that no moisture penetrates the nozzle when cleaning as this may damage the delicate dynamic speakers inside the earphones.
Changing the ear tips
The ear tips can be removed by carefully sliding them off the earphones. When replacing, check that the ear tips rubber notches are securely fastened in the locking groove.
Cleaning the mesh filter of the sound tube
If the mesh filter on the front of the sound tube shows signs of clogging, carefully use a brush to clean it.
For your safety
Hearing
These earphones are very powerful. Listening at high volumes for prolonged periods can cause permanent hearing damage. Always listen at a low to moderate volume and remember to rest your ears once in a while. If your ears start ringing or aching, remove the earphones immediately in order to rest your ears. Occupational Safety Health Administration (OSHA) has developed below noise exposure graph.
Traffic
Your a-JAYS Four+ effectively isolate external noise. This means you won't hear what's going on around you, which can be very hazardous in traffic. Never use your a-JAYS Four+ while driving a car, moped, bicycle or similar, or while jogging or walking through trafficked areas. We would like to remind you that listening to music in trafficked environments can lead to accidents.
