The primary aim of the following listening test is for use on a laptop computer, utilizing Foobar2000 (WASAPI event-driven mode) to play local lossless music. Considering the ample power supply provided by a computer, the resulting effect may surpass that of playback on a mobile phone. This difference is apparent in volume levels, with the laptop requiring only around 13% total volume for driving dynamic or planar magnetic headphones without inducing fatigue. The overall sound quality aligns with the direct and straightforward sound characteristics of the ESS chip output, akin to the Beam series, but without the previously observed issue of harsh high frequencies that could hinder listening comfort. While it may not match the musicality of the Beam3plus, this iteration demonstrates considerable advancement from the first-generation model and several preceding renditions, successfully achieving a "real and enjoyable" listening experience. This leap in performance comes as a pleasant surprise!

The overall balance of the three frequencies leans towards equilibrium, with a subtle focus on enhancing the mid-range for more refined listening experiences. What stands out to me about the ATOM3 is its proficiency in managing high frequencies. It retains the intricate and robust ESS decoding characteristics without overly emphasizing fine details, opting instead for a hint of softness. This translates into a more natural and harmonious sound profile, especially evident when enjoying classics like "One I Love" by a female artist. The ATOM3 doesn't present high frequencies as forcefully or starkly contrasting as some devices, fostering a smoother and more authentic listening experience. Even with high-sensitivity dynamic earphones, it maintains consistent performance without unpleasantly sharp highs, instilling confidence in its usage. Nevertheless, the ATOM3 does exhibit slightly limited high-frequency extension and average transient response. For individuals accustomed to transparent female vocals like myself, there remains a disparity in transparency and high-frequency impact when compared to our flagship model. This discrepancy may be more apparent when listening to ethereal tracks such as Faye Wong's "Still Here" or string instruments like guitars, where satisfaction levels may not be fully met.
   I was pleasantly impressed by the low-frequency performance of the ATOM3. It offers a notable amount of impact and robustness, paired with a level of flexibility in its control. Despite limitations in depth and speed, its rendition of tracks like "Poems Of Chinese Drums" is forceful, natural, and devoid of any overwhelming or displeasing aspects. Even upon repeated plays of dynamic tracks like "Beat It," it maintains its strength without feeling lacking, proving capable for handling large-scale performances. The unexpected proficiency in delivering a good sense of rhythm was a pleasant surprise.
