----------------------------------------------------------------------
【Voltage Compatibility】
When using electrical appliances, please note that they are designed for Japanese voltage specifications (90-110V), so if you use them with a different voltage, it may cause a malfunction.
【Plug Type】
Our products use Japanese plug types (A or B type).
Please use a conversion adapter if necessary.
【Important Note on Transformers and Adapters】
A transformer adjusts voltage to match your device’s requirements.
A conversion adapter only changes the plug shape and does not adjust voltage.
Using only a conversion adapter without a transformer may result in damage to the product.
【Liability】
We are not responsible for malfunctions or damages caused by improper use, such as operating the product without a transformer.

Experience deeply focused power with FATFREQ's second generation of Basscannon technology. It provides a well-controlled 25dB sub-bass shelf below 150Hz. FATFREQ's unique tubeless system provides a phase-accurate three-dimensional audio experience, precisely positioning instruments and vocals in a spacious environment. The Deuce excels in dynamics, capturing both delicate and powerful moments with ease. We offer the best of both worlds at an unmatched value.
For over a year, The Deuce has been carefully tuned with top reviewer HBB, known as Bad Guy Good Audio Reviews, and has gone through multiple iterations of tuning and design. Each phase focused on improving the clarity, depth, and dynamics of the sound. HBB's extensive hip-hop, rock, and classical collection greatly influenced The Deuce's tuning direction, and great effort was put into ensuring excellence in these genres. Our meticulous process also incorporated valuable feedback from professional musicians, with bassists, drummers, and synth keyboardists testing The Deuce in both production and live settings. The result of this dedication is an IEM that offers unparalleled sound quality and immersion.
FATFREQ's new acoustic system features an advanced acoustic network that manages the propagation of sound waves with optimal clarity and precision. A special bass chamber optimizes airflow for rich tone and deep bass. (Patent Pending) Using a unique dynamic woofer, bass chamber, and acoustic damping network, FATFREQ has successfully engineered an unprecedented deep bass of over 30dB. It is expertly controlled below 150Hz and has zero impact on the midrange. An innovation pioneered by FATFREQ for pure bass power.
FATFREQ uses a proprietary circuit to compensate for non-linear impedance in multi-driver systems. Different output impedances in all devices cause variations in frequency response. This technology ensures a consistent frequency response whether all IEMs (in-ear monitors) are connected to a mic pack, mixer board, phone, or dedicated DAP.
SONAR LA TROMPA Inspired by traditional French horn anatomy, FATFREQ uses an exponential horn curve to provide gain control and acoustically improve treble tone. This provides smooth, natural highs and solid resonance in the mid-bass.
