ATH-TWX9 earbuds with accessories and ear tips

In-ear headphones are only as good as their fit — and Audio-Technica includes a plethora of ear tip options.

Of course, when it comes to the true-wireless category, the convenience features are just as important. And these 100% wire-free headphones offer active noise cancellation, touch controls, and work with a free downloadable app for Apple and Android phones. It lets you control the sound signature, level of noise cancellation, and can help track down lost earbuds using your phone's GPS.

Advanced Bluetooth for a strong connection

Music plays wirelessly via Bluetooth 5.2, a newer, reliable version of Bluetooth. It includes aptX® Adaptive technology. This versatile wireless audio codec automatically detects if you're in an area with competing Bluetooth signals and adjusts accordingly. In those crowded areas, it will optimize reliability over sound quality.

In places with no competing wireless signals, it will better preserve the audio quality with compatible phones. Speaking of phones, powerful microphones work with aptX noise-suppression technology to keep calls clear, too.

Solid battery life

You get about six hours of listening on a single charge, which is above average for wireless earbuds with noise cancellation. The included charging case banks up to 12 and a half hours of power to recharge the earbuds on the move. It also has a built-in UV light to help sterilize the earbuds while they're charging.

Product Research


Overview: The Audio-Technica ATH-TWX9 true wireless earbuds provides a high-fidelity listening experience through many comfort and convenience features. You can listen in private with hybrid noise cancelling, or stay aware with hear-through modes. The headphones let you listen to high-resolution audio files up to 24-bit/96kHz through innovative codecs and software from Qualcomm. The earbuds include three types of eartips in four sizes to help you find the proper fit. The ATH-TWX9 also comes with a Qi-enabled charging case and USB-C charging cable.

Drivers: The TWX9s utilize specially-designed 5.8mm high-resolution dynamic drivers that deliver frequencies beyond the limits of human hearing that add depth, detail, and richness to your music.

Eartips: Included with the headphones are four sizes and three lengths of eartips. The eartips are made of a hybrid material of hard and soft silicone, and provide a secure fit and a higher level of comfort for long listening sessions. The eartips come in standard, long, and short lengths. Each length of eartip is available in XS, S, M, and L sizes.

Splash-proof: The ATH-TWX9 earbuds are IPX4-rated for their rain and water splashproof design, so you can wear them while you workout or when in inclement weather. They are not designed to be immersed in water.

Bluetooth 5.2: The earbuds have Bluetooth 5.2 which has a range of approximately 33 feet. They support SBC, AAC, and Qualcomm aptX and aptX Adaptive codecs. For an advanced listening experience, you can enjoy Qualcomm's Snapdragon Sound™ platform. Snapdragon Sound™ pairs with the earbuds' high-resolution drivers to elevate the sound of your music, videos, gaming, and phone calls, when used with compatible devices. When Snapdragon Sound™ is enabled, the transmission band is expanded from 20Hz-20kHz to 10Hz-47kHz, allowing you to listen to hi-res audio files up to 24-bit/96kHz in all their glory. Snapdragon Sound™ also reduces the sound delay (latency) to make your games and videos much more enjoyable. The earbuds also feature Multipoint pairing to let you connect with two Bluetooth devices simultaneously and easily switch between them.

MEMS Microphones: Each earbud is equipped with dual MEMS (micro-electromechanical system) microphones. The mics feature beamforming technology to focus primarily on your voice, while Qualcomm's cVc Generation 8 makes sure your phone calls are crystal clear. In addition, sidetone circuitry lets you hear your voice in the headphones when you make calls to improve conversations.

Ambience Control: The ATH-TWX9s have digital hybrid Active Noise Cancelling (ANC) that eliminates distracting ambient sounds to let you listen in quiet. Each earbud has two microphones to pick up ambient noise. When ANC is enabled, a high-precision noise-cancelling processor and proprietary filter eliminate the ambient noise with an opposite-phased signal. There are five preset noise-cancelling modes to choose from. The Hear-through function allows you to hear ambient sounds to stay aware of your surroundings or conduct conversations. You can hear ambient sounds, plus your own voice, so you can talk to others without removing the earbuds.

360 Reality Audio: The TWX9 earbuds feature Sony's 360 Reality Audio to provide a truly immersive music experience. The technology places individual sounds such as voices, instruments, and other elements into a 360° spherical sound field. Artists and creators use this 360 Spatial Sound technology to put you inside the music. You can find content with 360 Reality Audio in many streaming platforms, many of which require a subscription.

Touch Controls/Multi-function Buttons: You can adjust the volume and control music playback and phone calls through the touch-sensitive areas on the outside of the earbud, and through multi-function buttons on the posts. A circular area on the back of the earbud enables the Ambience Controls (ANC, Hear-through, Talk-through). The multi-function buttons (MFB) are located on the front-facing portion of the earbud post. Pressing the left MFB controls the volume up (1x) or down (2x) by one level. Music playback functions are controlled on the right earbud by pressing the MFB for pause/play (1x), next track (2x), or previous track (3x). When a call comes in, you can answer it with a press of either button. The microphones are also compatible with various voice assistants, such as Alexa, Google, and Siri, and can be activated through a long press (2 sec) of the touch sensor on the right headphone.

Voice Guidance: The ATH-TWX9 has voice guidance (in English) to confirm commands or provide low battery warnings. Each time you pair the headphones with a Bluetooth device, activate or deactivate Ambience Controls, or Play/Pause your music, a voice will confirm your actions.

Rechargeable Batteries: Each earbud has a built-in 3.85-volt Lithium-ion battery that provides approximately 6 hours of continuous music playback. The charging case provides an additional 12.5 hours of battery life for a total of 18.5 hours. The earbuds charge when they are placed in the charging case, and can go from 0% to 100% charged in about 2.5 hours, depending on conditions. The charging case can be charged in approximately 3.5 hours when using the provided USB cable. The case is Qi wireless charging compatible, and can fully charge in about 5 hours. Charging times are longer when the ambient temperature is above 86°F or below 50°F.

Sanitizing Function: Not only can you charge the earbuds in the case, you can also keep them sanitized. When the earbuds are placed in the charging case and the cover is closed, they will be automatically sanitized by a deep UV LED. The UV sterilization eliminates bacteria and viruses from the surface of the headphones. During this process, the five LEDs on the front of the case will flash purple to remind you to wait until the process is finished before opening. This sanitizing process is only performed once an hour no matter how many times you place the headphones in the case. If the process is interrupted by the case being opened, the procedure will resume once the cover is closed again.

Note: The system is more than 99% effective against E. coli and bacteriophage viruses, and more than 90% effective against Staphylococcus aureus, but it is not effective against all bacteria and viruses. The effectiveness against the novel coronavirus (COVID-19) has not been verified.

A-T Connect: The Audio-Technica Connect app, available for iOS and Android devices, enhances your listening experience. You can make adjustments to the sound of your earbuds through an EQ and Bass Boost function. In the app, you can set the volume range to 16 steps (large increments), 32 steps (medium increments), or 64 steps (small increments). The app also lets you view the battery level of each earbud and the charging case at a glance. The Connect app is available from Google Play for devices with Android 9 and up, and from the Apple App Store for iPhone and iPod touch (requires iOS 15.0 or later).
