■ Equipped with digital noise canceling function
・ Equipped with ""AI (Artificial Intelligence) noise canceling function"" that analyzes surrounding noise with one button and automatically selects the optimal canceling mode
The filter circuit that controls the cancellation amount has been digitized and controlled by software, making it possible to switch filter characteristics. Noise is analyzed with one button and the optimal mode is automatically selected from three modes. Effective noise cancellation is performed according to noise with various characteristics depending on the environment.

■ Long stamina (quick charging compatible)
・ Achieves long-term wireless listening of up to 35 hours. It also supports quick charging, which allows 60 minutes of playback with 10 minutes of charging. It is possible to charge immediately even when you suddenly go out.

■ Compatible with the dedicated app ""Headphones Connect""
・ Surround (VPT)
You can change the sound field setting from 5 types: Arena / Club / Outdoor stage / Concert Hall / OFF. You can enjoy music with your favorite taste according to your mood and usage scene of the day.

■Equalizer adjustment
-You can choose from 8 presets such as ""Relaxed"" and ""Bass Boost"", or customize the equalizer settings to your liking.

■Other
-You can also turn noise canceling on/off and switch sound quality modes.

■Equipped with ""DSEE"" to clearly reproduce the high range of compressed sound sources
- ""DSEE"" effectively complements the high range that is often lost in compressed sound sources. Using MP3 and Bluetooth transmission codecs, compressed sound sources are reproduced with a wide sound that is closer to the original sound. Even if the compression rate is increased, there is little deterioration in sound quality, and you can enjoy natural sound that is easy to listen to.

■40mm driver unit with high magnetic force neodymium magnet
-Improves sound resolution and achieves balanced high-quality sound reproduction from rich low range to clear mid-high range.

■Beat response control that accurately reproduces the rhythm of deep bass
-The port (ventilation hole) on the top of the housing controls the air flow resistance in the low range. By optimizing the operation of the diaphragm, the low-frequency transient characteristics are improved and the rhythm is accurately reproduced.

■Ear-conscious design that improves fit and sound quality
・The driver unit is positioned to match the angle of the human ear. By reducing the feeling of pressure on the ear, natural sound quality and comfortable fit are achieved.

■Inward axis structure
・Adopts a unique hanger structure. The rotation axis of the housing is facing inward to improve wearing stability.

■Supports activation of smartphone voice assistant functions such as Siri and Google apps
・You can make calls, play music, and do simple research such as weather forecasts by operating the headphones and voice control without taking out your smartphone.

■Easy operation of players such as smartphones with buttons on your ears
・By operating the buttons on the housing on the R side, you can forward/rewind songs, play/pause, and adjust the volume of music players such as smartphones connected via Bluetooth, so you can easily operate them without taking the player out of your pocket. You can also receive and end calls. You can receive and talk without picking up your smartphone, and when you finish, music playback will start again seamlessly.

■Convenient Bluetooth function
