[Final] ZE300 Wireless Earphones Smart Package, Bonus Sticker Included Noise Cancelling, 4g Single Earbud, Comfortable Fit BLACK Black

[Smart Package Model with Bonus Sticker] Ultra-small size of just 4g per side + noise canceling technology – perfect for music and videos! [Important Notes Before Use] Please peel off the insulating stickers attached to the metal contact points on both earbuds.

・[Ultra-small Design of 4g per Side] The ZE300 adopts the ultra-small housing of the [COTSUBU] series, which has cumulatively shipped over 5 million units. It is the smallest and lightest noise-canceling earphone in our lineup, about 20% smaller in volume than the ZE3000 SV, making it less likely to fall out even for those with small ears and recommended for sleep listening. We have also completely redesigned the internal mechanism to upgrade the fundamental aspects of sound quality and ease of use. ・[Equipped with “Noise Canceling” that Balances Sound Quality and Sound Isolation] In addition to the high sound isolation performance due to its ultra-small size, it features unusual “noise canceling” for this size. Using our unique algorithm, it combines noise canceling that balances sound quality and sound isolation with an “ambient mode” that makes it easier to hear surrounding sounds. You can switch between them with a single touch on the L side, allowing you to freely switch even while wearing them, for example, when you suddenly want to hear announcements on a train. ・[Three Modes Can Be Selected] This product allows you to select modes, in addition to the standard “noise canceling mode” and “ambient mode,” you can also turn off both functions. ・[Equipped with “Airflow Port” to Distribute Pressure] Equipped with an “airflow port” that distributes pressure even when the earphones are pressed from the outside. By adjusting the increasing pressure in the ear canal, it reduces the burden on the eardrum while also reducing the burden on the internal driver. It realizes durability that is hard to break even when used while lying down, and is also optimal for sleep listening. ・[Equipped with New Function “Touch Operation Disable Function”] The earphone body supports touch operation, allowing you to operate music playback/pause and calls/end calls more easily. By tapping it five times in a row, it will become the “touch operation disable function,” and subsequent touch operations will be disabled. This prevents accidental operation when your hand accidentally touches the earphones, so you can concentrate on content for longer and use it while sleeping. ・[Notes on Use] 〈Cannot Connect or Charge〉 Please peel off the insulating stickers attached to the metal contact points on both earbuds.
