Audio-Technica has introduced its top-of-the-line ATH-TWX9MK2 earbuds, which come loaded with several enhanced and innovative features designed for those who love high-quality music.

Sound Quality and Technology

The ATH-TWX9MK2 is equipped with 5.8 mm Pure Motion Drivers, boasting a frequency response range from 10 Hz to 40 kHz and a sensitivity rating of 105dB/mW. These advanced drivers feature a tough, beryllium-coated center dome and an elastic polyurethane outer dome, powered by a tiny voice coil and dampened with a Sefar acoustic mesh. According to the company, these earbuds support high-resolution audio playback via aptX Adaptive Audio (up to 96 kHz 24-bit) and are compatible with Hi-Res Audio Wireless.

Noise Cancellation Features

Each earbud features both feed-forward and feed-backward MEMS microphones to enhance the active noise cancellation (ANC) capabilities, surpassing the performance of the previous model, as stated by A-T. The microphones deliver a frequency response from 20 Hz to 10 kHz with a sensitivity of −38dB (1V/Pa at 1 kHz). They function as a beamforming microphone system, utilizing Qualcomm’s cVc Generation 8.0 technology, which helps to clearly capture the user’s voice even in noisy surroundings.

Personalization and Comfort

These earbuds can automatically adjust the ANC based on the user’s ears by emitting a reference tone that the microphones pick up to find the optimal settings. Additionally, a long touch on the earbuds allows for manual optimization of ANC for the current setting if the five available presets aren’t enough. The hear-through feature lets users listen to conversations around them without needing to take out the earbuds. To ensure a comfortable fit, four sizes of ear tips in three different heights are included.

When users are not engaged in music or calls, the ATH-TWX9MK2 can play calming nature sounds and meditation audio, helping to unwind after a busy day or aiding concentration while studying.

Battery Life and Design

The earbuds offer a runtime of up to six hours with ANC activated and up to 18.5 hours when using the charging case. Each earbud weighs 5.5 g (0.19 oz.), while the case weighs 55 g (1.94 oz.). Additionally, the case is equipped with Deep-UV LEDs that sanitize the earbuds with germicidal light, effectively killing bacteria and viruses. Users can recharge the case using a USB-C power supply or a wireless charger.

The Audio-Technica ATH-TWX9MK2 earbuds, available in black or white, have a manufacturer’s suggested retail price of 38,500 yen (approximately $265). They are expected to launch on July 11, 2025, in Japan and will soon be available at the Audio-Technica store on Amazon US.
