With excellent sound insulation and high-performance noise canceling technology, you can enjoy music without being affected by surrounding sounds.

Scheduled for release on November 13, 2020

■High-quality design φ5.8mm driver that reproduces the world of music
・Specially designed 5.8mm driver and strong magnetic magnet increase driving force and express a rich sound field. The center dome of the diaphragm is coated with DLC (Diamond Like Carbon) to improve high-frequency characteristics, reproducing clear mid-high frequencies.

■Stainless steel conduit (PAT.P) in close contact with the driver
・Stainless steel conduit is placed coaxially with the driver unit. It reduces sound loss and improves reproducibility.

■Stainless steel acoustic register that creates a natural sound field
・A register is installed at the tip of the conduit to optimize air flow. It brings out the original performance of the driver.

■ Rubycon PML-CAP capacitor for low noise and low distortion
・Uses a chip-type thin-film polymer laminated capacitor that is an ultra-miniaturized version of the audio-grade capacitor used in high-end amplifiers. Stable current suppresses noise and sound distortion, reproducing high-purity sound.

■Supports high-quality aptX/AAC codec

■Creates a listening environment that is immersive in sound
・Combines high sound insulation by wearing with active noise canceling function, allowing you to immediately immerse yourself in music and videos.

■Call performance that enhances communication. Beamforming technology for clear calls
・Equipped with a small, high-performance MEMS (Micro Electro Mechanical Systems) microphone inside the earphone housing. Beamforming technology using two microphones improves the accuracy of call quality by emphasizing the voice band while giving directionality toward the speaker's mouth, and delivers a clear voice to the other party.

■ Compatible with the dedicated app ""Connect""

■ Compatible with the ""hear-through function"" that allows you to hear surrounding sounds

■ Comfortable listening with less sound dropouts
・ Stable connectivity is ensured by adopting the latest Bluetooth chip and antenna tuning that is optimal for the small body. It achieves performance that makes it difficult for sound to be interrupted even at terminal stations and in crowds.

■ Approximately 7 hours of continuous playback, up to approximately 20 hours of playback*
・ Approximately 7 hours of continuous playback is possible with a full charge of the earphones alone. If the earphones and charging case are fully charged, you can use them for up to approximately 20 hours.

■ Can be charged in a short time before going out
・ Approximately 15 minutes of charging allows for approximately 100 minutes* of continuous playback. Even if you forget to charge, the earphones will be ready by the time you get ready.
* Varies depending on usage conditions.

■Complies with Bluetooth standard Ver. 5.0

■Multi-pairing function that allows multiple devices to be registered

■Supports SCMS-T content protection method that allows wireless viewing of OneSeg

■Supports voice guide function
-Power ON/OFF, pairing status, and battery level (High, Medium, Low) are notified by voice.

良いですよ、コレ（*´ω｀*）

投稿者名Reviewed by：せいちゃん【福岡県】

同じ価格帯で人気の高いSONYのノイキャンとさんざん迷ったあげくこちらを選択。
選んだ決めてはマイクの性能。
指向性がなんたらかんたらと説明があったので「外音と混ざって聞き取りにくいと噂のあっちよりこっちかな」と。通話の時のマイクの指向性大事。
ZOOM会議で使いたいので。
音質は素直に原音を再現している印象。
もともと極端な重低音とかいらないし、ヘッドフォンとかイヤホンで極端に音をいじる意味がわからん。
原音の再現と解像度に悦びを求める僕にはオーテクさん最高です。
ノイキャン、ヒアスルー、OFFの切り替えも簡単で使いやすい。
ノイキャン性能は完全な無音とはいかないけど、ほどほどでいいんじゃないかな。ノイズも完全に消えるとなんか不安になるし。
aptxを選択してイコライザーをボーカル重視に、充分高音質です。
イヤホンのケーブルのわずらわしさからもお気に入りのイヤホンが断線して片耳になっちゃったショックからも解放されて大満足でござるよ。
買って良かったです。（*´ω｀*）
