Even though Atom3 is smaller in size, its specifications remain top-notch. It still boasts the powerful ES9280AC PRO DAC from ESS, known for its exceptional performance. Atom3 is essentially a tweaked version of the ES9281AC PRO, with the removal of the less essential MQA hardware decoding function. Despite this, its overall capabilities are still impressive, supporting hardware decoding up to PCM768kHz/DSD512. Additionally, the Atom3 retains its independent femtosecond-level crystal oscillator and high-quality Panasonic thin film capacitors. Overall, while the Atom3 may lack in power, its sound quality is guaranteed. For daily listening to popular songs during commutes, the Atom3 offers rich, solid sound with beautiful and nuanced vocals. In contrast to the warmer sound of Atom2,  Atom3 leans more towards neutrality, resulting in a bright, youthful sound profile that appeals to contemporary audiophiles. Atom3 prioritizes mid-frequency performance, which aligns well with most earphones in its price range. For those who prioritize sound quality, considering Beam 3s or the more advanced Beam 3plus or Beam 3pro is recommended.

Due to its compact size, Atom3 provides sufficient power for balanced-armature IEM or low-impedance, high-sensitivity dynamic driver IEM. While it may not match the dynamic performance of Audirect Beam series, the Atom3 shines in mid-frequency performance. Given that most earphones under a thousand dollars emphasize mid-range frequencies, Atom3's compatibility with various earphones is quite satisfactory. For audiophiles seeking premium sound quality, exploring options like Beam 3s, Beam 3plus, or Beam 3pro would be beneficial. Moreover, despite its average dynamics, Atom3 handles high and low frequencies adeptly, ensuring an enjoyable listening experience, especially during daily commutes. Notably, Atom3 incorporates low-power management chips, reducing strain on phone battery life and minimizing heat output during operation. Even after extended use, Atom3 remains only mildly warm to the touch, highlighting its effective heat control mechanisms.
