Month after month our reliable earphones will deliver a consistently high quality audio performance offering enhanced detail and a wide sound-stage; and all from a surprisingly slimline design.

Slimline design

The combination of t-JAYS angled sound tube and flat design makes them one of the most comfortable and ergonomically dynamic earphones on the market despite boasting a large and powerful 10mm speaker. You can wear them in the standard earphone position or if you’re being more active, why not anchor them behind your ear. This, together with the option to split the cable from between 60cm and 130cm make them extremely versatile wherever they accompany you.

The sound of science

Connect your t-JAYS to an iPod, a phone or any other media player using the 3.5mm jack and take in the wide vista of sound delivered by the powerful neodymium driven 10mm speaker engineered by JAYS.

Versatile and ergonomic
  • Choose between 5 different sizes of soft silicone sleeves to ensure a perfect ear fit
  • Cable extension included, giving flexibility of earphone usage
  • Use the rigid case to protect your earphones on the go
  • The ultra-slim design means no discomfort should you happen to fall asleep with them still in
Nothing but the music

The t-JAYS One uses JAYS silicone sleeves which work to lower any intrusive surrounding noise by up to 40dB, ensuring a better listening experience in ambient environments. And in turn this means the 10mm earphone speaker does not distort as the media player’s amplifier does not get overloaded.

A natural, comfortable fit - choose from 5 pairs of silicone sleeves included

t-JAYS One comes with 5 soft silicone sleeves in sizes ranging from XXS to L. These sleeves envelop the earpiece meaning all t-JAYS users can achieve a natural, comfortable fit, and maximum external sound insulation. In addition to the standard 60cm earphone cable, an extension cable is available giving you a further 70cms to play with. Maximize flexibility of usage options; keep your music source in your jeans pocket, jacket pocket or on an armband and have the right length of cable each time to help avoid annoying tangles. Use the gift box included to store your silicone sleeves and accessories when not in use or to protect them when you’re on the go.

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 its 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.

This is JAYS - Love music

Our mission started out in Sweden in a small scale with a global scope of not letting go when it comes to stronger musical experiences in the canvas of all people’s everyday life. People are pretty much the same over the world and we all strive towards better in all things that we do and that we are. Our way of making better is to do exactly what we do, greatly enhancing the experience of mobile music.

We know that our fans and users makes a JAYS Generation, that always looks for better and expect us to provide it. Simply because we can, we keep it simple and develop advanced hi-tech in black and white at affordable prices in innovative award-winning products.

Simplicity and quality is always in fashion and we have a great love for music, art and innovation. Technology is just our means for making it human.

This is our way of passing on our vision to our respected users, setting a new standard on what to expect when expecting better. As all good things, we are a work in progress, but we have come a long way in a few years. We would love it if you would like to join us, proving that we are doing it right.
