Model X is the world's best-sounding true wireless earbuds developed from the ground-up to deliver the most incredible hi-fi audio in the rock-solid wireless connection.  Each details, from intuitive touch-control, IPX-5 sweat-proofing, all-day battery life, noise cancellation to smart assistant compatibility has been carefully considered and put together in a fluid user-experience package.  These earbuds will revolutionize the way you listen to music.

Model X automatically turns on, enters pairing mode and turns off when you are done using it.

• When Model X is taken out of the charging case, it turns on automatically.
• Model X then automatically enters pairing mode, discoverable from Bluetooth source device around.
• When Model X is put back inside the charging case, it automatically disconnects from the source device and turns off.

We have been developing some of the highest quality audio for more than 4 years, ranging from full-range dynamic drivers, balanced armatures to planar magnetic drivers.  10mm dynamic driver used in the Model X is a pinnacle of driver efficiency tuned specifically to work with its true wireless Bluetooth module at its maximum capability.  The driver inside Model X stands out largely for the following reasons:

• Its circumference is 10mm, making it one of the biggest driver size fitted into a compact and ergonomic true wireless earbuds.
• 10mm is the ideal size of transducer to achieve high-fidelity both in terms of the sonic quality and volume output.
• Its driver diaphragm is coated in graphene material, which markedly increases rigidity of the diaphragm while keeping its weight at the minimum resulting in an ultra-low distortion and a fast, transient response throughout the frequency range.

Intuitive touch gesture control allows seamless operation of Model X and provide fluid and unobstructed user-experience.

• Tap Once : Play / pause music, answer / end phone calls
• Tap Twice : Previous / skip music track
• Tap and Hold : Volume control
• Tap Three times : Activate voice control (Siri / Google Assistant)

True wireless solutions have been going through turbulent changes for the last 3 years.  Initial solutions have been plagued with severe drawbacks in the basic functions.  We've developed and scrapped over 10 different solutions in the course of 3 years, and finally reached the level of connection stability we were targeting with the Model X via matured Bluetooth 5.0 protocol.

With Bluetooth 5.0, you get the strongest, most reliable connection and seamless connectivity between your devices. Strong connection and speed allows more detailed and robust audio fidelity transmission and zero audio-video lag.

Beyond speed and strength of connectivity, Bluetooth 5.0 provides enhanced security compared to its previous versions to keep your personal information secure.

Model X is a byproduct of countless designs to ensure universal fitment for various ear shapes and sizes.  The nozzle length is purposely elongated to be inserted deep into the ear canal and the round and compact earbud body allows it to fit ergonomically in the concha.

Universal and ergonomic design provides numerous unique benefits that improve the user experience of Model X.  Such benefits are as followed:

• Universal fitment without needing additional ear hooks or guide.
• Maximum noise isolation up to 23dB from deep insertion of nozzle.

Model X is rated at IPX-5 sweatproof, ideal for most sports application.  Its ergonomic / secure-fit design combined with sweatproof capability makes Model X your perfect work-out companion.

Being truly wireless means that the Model X never gets in your way, but helps you get to where you want to be. We developed Model X to have strong and secure connectivity to your device with a working distance of 35 ft, so you never drop a call, lose connection, or miss a moment.

Model X uses a custom-made LDS antenna to increase bandwidth and signal reception while reducing interference and unwanted noise.  Additionally, pocket connectivity test has been performed using iPhone XS / Pixel 3 / Galaxy S9 / V40 in the front-left, front-right, back-left, back-right pockets over an extended period of time to ensure no connectivity loss occurred during normal commute.

Built-in, low-noise, high sensitivity microphone with cVc noise-cancellation allows clear stereo phone calls on-the go.

It was the respect for all musicians of the past, present and future. It was for the struggling instrumental buried under the heavy bass line. It was for the audiophiles craving that crystal clear and mind-blowing detail.

ADVANCED SOUND GROUP began as a small Kickstarter campaign in 2015 and naturally grew into a bigger body that thrives on the enthusiasm and passion for music. We design, develop and produce ground-breaking audio products that span widely from earphones, headphones, DAC / amp to musical instruments. We are focusing on staying forefront with the latest proprietary audio technology, while continuing to explore creative ways to allow everyone to experience the audiophile-grade sound.

In our core principle, there lies respect for all musicians as creators and facilitators of content so deeply rooted in human emotion. We recognize the importance of music and the impact it could have in everyone's life, and we actively collaborate and support those who are practicing, creating or performing it around the globe.

We have an open mind and open doors for new ways to collaborate with musicians, audio engineers, manufacturers and brands - as we strive to mature into a platform where the advanced sound converge.
