Further to the Sound of Japan

The WE-BD21 features a hybrid triple driver, largely unprecedented among wireless headphones. In addition, by adopting aptX HD, which boasts 256 times the resolution of existing codecs (based on theoretical values), such as SBC, the headphones faithfully and completely recreate auditory information.

Hybrid Triple Drive

The combination of a dynamic driver with a broad playback frequency band and minimal distortion in low frequency bands, with a balanced armature driver that has solid mid and high frequency playback, is said to be the ideal set up for earphones. Due to the difficulty of miniaturization and the significant energy demands this entails, examples of this set up among wireless headphones are limited. At AVIOT, our long-awaited energy efficiency technology, and miniaturization know-how, has allowed us to overcome these issues. As a result, our products can outperform wired headphones from the same price band in terms of audio quality.

The Stamina to Playback for up to 13 Hours

The WE-BD21d allows for up to 13 hours of continuous playback without sacrificing sound quality, all while getting rid of heavy and annoying mid-cable batteries, in favor of mounting an invisible battery.

High-quality Sound Supported by High-quality Parts

The WE-BD21d boasts a non-magnetic body, and high-rigidity dialuminium case that effectively blocks external noise. The sides of the casing also feature a beautiful knurling pattern, engraved in order to reduce vibration in the casing. The left-right connecting cable is reinforced with Kevlar, and the earpieces are CP100Z from SpinFit. Every last detail has been looked at to ensure the highest possible audio quality.
