Galileo’s resin shells boast an enchanting blend of swirling blue, brown, and white hues, evoking the mystique of the universe itself on their faceplates. Complementing this cosmic design, the main body of the shells dons a rich, dark opaque colour, adding a touch of elegance to their overall appearance.
Beyond their aesthetic allure, these shells have proven to be exceptionally comfortable for my ears. Their fit is organic and snug, affording me the luxury of all-day wear without any discomfort, while the above-average noise isolation ensures an immersive listening experience.
Accompanying the shells is a high-quality silver-plated copper cable, reminiscent of the beloved S12 and S12 Pro cables, albeit with a slimmer and more flexible profile. The cable handles beautifully, boasting minimal microphonics.
The only slight drawback lies in the pre-formed ear hooks, whose aggressive curve can pose fit issues. However, a simple solution is heating the cable with a hairdryer, easing the bend and granting a more tailored fit.
Gear used for testing includes the xDuoo XD05 Bal2, SMSL DO200 MKII and Cayin RU6. Galileo has a low impedance and average sensitivity so it’s fairly easy to drive and thus does not require additional amplification.
The sound signature is neutral with a subtle bass boost. The first thing I noticed about Galileo’s sound is its clarity and timbre which are both good. However, it’s a little restrained in the bass and the treble fall-off is fairly dramatic. As a result, although the sound is good for things like vocals and acoustic music, it lacks the dynamics and engagement to be a solid all-rounder (at least for my taste).
The bass of the Letshuoer Galileo IEM is characterized as tight and concise, yet it falls slightly short in authority and impact. Despite this, the bass response plays a vital role in opening up the midrange, creating a more spacious and immersive sound signature. A noteworthy advantage is that the bass does not muddy or smear the vocals or instruments, preserving clarity in the overall audio presentation.
While the sub-bass extension is decent, the Galileo struggles to reproduce the deepest notes, which might be a minor limitation for bass enthusiasts or those seeking a more pronounced low-end performance. However, for listeners who prioritize a well-balanced and clear midrange, Galileo’s bass capabilities may still offer an enjoyable and engaging listening experience.
The midrange of the Letshuoer Galileo IEM is characterized by good clarity and accurate timbre, resulting in a natural and organic tone. The tuning is neutral, providing a balanced representation of instruments and vocals.
Vocals, particularly female vocals, take prominence with a forward and lively presentation. They exhibit a sweet, and emotionally engaging quality without any aggressive attributes. Male vocals might sound slightly lean but remain articulate and convincing.
The treble of the Letshuoer Galileo IEM is crisp yet smooth, striking a balance between clarity and a pleasing listening experience. While not particularly airy, the treble still manages to deliver a satisfactory level of detail retrieval, though it falls short of being exceptional.
One commendable aspect is the absence of sibilance, which ensures that the treble remains free from any harsh or sharp tones. This allows for a comfortable and enjoyable listening session, especially during extended use.
Soundstage and Technical Performance
Although its dimensions are decent, Galileo lacks depth in its soundstage, which means that the audio may not create a strong sense of distance or spatial positioning. This could lead to a more upfront and intimate presentation, but it may not provide a sense of depth and distance.
Galileo performs well in terms of instrument separation, allowing distinct instruments to be heard with clarity and precision. This aids in maintaining a clear and organized sonic presentation.
In conclusion, the Letshuoer x Gizaudio Galileo IEM is not the best all-rounder but it excels in acoustic music and vocals. The bass is tight, preserving clarity, but lacks some impact. The midrange is natural, with forward and lively female vocals. The treble is crisp yet smooth without sibilance. The soundstage is average with good instrument separation but limited depth.
Despite not standing out in audio quality, the Galileo offers good value due to the calibre of its design and accessories. It’s a pretty solid product and most listeners should be pleased with what they hear, unless they’re looking for something dynamic and fun with impactful bass.
