ZE300

Ultra-small design weighing only 4g per side

The ZE300 is a new design based on the extremely small chassis of the ag brand "COTSUBU series", which has shipped over 500,000 units in total. These are the smallest and lightest of our noise canceling earphones, and are approximately 20% smaller in volume than the ZE3000SV, making them ideal for use as sleeping headphones, even for those with small ears. In addition, the internal mechanism has been completely redesigned to improve the fundamental aspects of sound quality and usability.

Equipped with "noise canceling" that combines sound quality and sound insulation performance

In addition to the high sound insulation performance due to its extremely small size, it is also equipped with "noise canceling", which is unusual for this size. In addition to noise canceling that uses a unique algorithm to achieve both sound quality and sound insulation, it also features an "ambient mode" that makes it easier to hear surrounding sounds. Switching can be done with a single touch on the L side, so you can switch freely while wearing it, such as when you want to hear announcements instantly on a train.

Three modes can be switched

This product allows mode selection, and in addition to the normal "noise canceling mode" and "ambient mode", it is also possible to turn off both functions.

Equipped with an "air flow port" that disperses pressure

Equipped with an "air flow port" that disperses pressure even when pressure is applied to the earphones from the outside. By adjusting the increasing pressure in the ear canal, it relieves the burden on the eardrum and at the same time reduces the burden on the internal driver. It is durable enough to not break even when used while lying down, making it ideal for sleeping.

Equipped with a "touch operation disabling function" that is perfect for sleeping.

The earphones support touch operations, making it easier to play/pause music and make/end calls. Also, if you tap the button 5 times in a row, it will become a "touch operation disabled function" and future touch operations will be disabled.
In addition to preventing the earphones from malfunctioning if you accidentally touch them, the announcement sound and LED lights are also turned off, so you can use them when you want to concentrate on content for a long time or while sleeping.
