What customers say
The 64 Audio A3t earns high praise for its exceptional clarity and balanced sound, ideal for detailed audio enjoyment. A standout feature is the proprietary apex technology, which users find significantly reduces listening fatigue during long sessions by managing internal pressure. This superior comfort, combined with excellent passive noise isolation from the custom fit, truly elevates the overall experience. While the cost is premium, the blend of technical performance and outstanding wearability establishes the A3t as a highly valued and reliable monitor for serious audio enthusiasts.
Know before you buy
The A3t is designed for accuracy and detail, utilizing a three-way passive crossover and balanced armature drivers to provide a neutral, reference-grade sound. Its consistent frequency response ensures that what you hear is an honest representation of your mix, regardless of the audio source.
Apex technology uses a pressure-relief vent to release air trapped in the ear canal. This reduces listener fatigue during long sessions and improves the soundstage, allowing for a more natural and comfortable listening experience.
Yes. With an impedance of 11Ω, the A3t is highly efficient and easy to drive, meaning it does not require a powerful dedicated amplifier to reach optimal volume levels or sound quality.
These modules determine the level of passive noise isolation. The m20 module provides 20dB of isolation, which is ideal for noisy environments, while the m15 module offers 15dB of isolation for a slightly more open feel.
3Dfit is a precision manufacturing process that creates a custom-fit shell based on your ear impressions. This ensures the monitors sit securely and comfortably in your ear, which is essential for maintaining a consistent seal and accurate bass response.
The tia (Tubeless In-ear Audio) driver is designed without the traditional sound tube or damper. This eliminates resonance and distortion, resulting in a clearer, more transparent high-frequency response.
