The standout performer that resonated with me the most was the FiiO flagship IEM - FH7. While it's a quad-BA and 1 dynamic drivers, renowned for its ease of driving and high-quality audio, using it directly with a mobile phone only gives you a glimpse of the stunning details and excellent transient dynamics. However, after integrating the Beam 3Plus into the setup, it felt as though the seal on the FH7 had been entirely unlocked, leading to an entirely different listening experience. The sense of spaciousness elevated the entire soundstage to perform with a three-dimensional and intricate quality, evolving from simple positional audio to a surround-style expansive spatial sense, with layers of rapidly expanding room that were, in a word, incomparable and indescribable. It almost felt like I was listening to 7.1 surround sound headphones! Despite maintaining all the original details, the transformation from linear to spatial forms introduced a subtle smoothness and distinct directionality. In both vocal and instrumental music, it exceeded the expectations of its price range, significantly elevating the FH7's listening performance.

The Audirect Beam 3Plus is a high-end device, equipped with USB DAC and Bluetooth receiver capabilities. Its utilization of the high-spec ES9281AC chip provides potent decoding effects, featuring both 3.5mm single-ended and 4.4mm balanced output. The Bluetooth receiver segment delivers exceptional sound quality, optimized spatial performance, smooth low frequencies, and overall superior performance, especially for classic vocal repertoire. It effectively enhances the sound quality across a spectrum of headphones, particularly those of the high-end variety. As such, the Beam 3Plus proves a convenient Bluetooth tool for audiophiles, offering a journey into the realm of Hi-Fi headphone experiences that's accessible for both seasoned enthusiasts and new users alike.
