Product Strengths

• Delivers a 'smooth, punchy, and crisp listening experience that is perfect for any musician, audiophile, or studio engineer'
• The sound is 'transparent, resolving, deep reaching, airy sounding, having an amazing note separation, shrinking the gap between tiny IEMs and also medium sized open-back headphones'
• The body is much smaller than usual, made out of hard plastics, not metal, so it's barely felt in the hand and in the ears
• Transparent, resolving, deep reaching, airy sounding, having an amazing note separation
• Manages to balance the frequency response without becoming boomy in the bass, muddy in the mid-range, or ear slashing in the treble

Product Considerations

• A reviewer wished for a slightly stronger kick and slam in the bass
• The upper midrange could use a boost
• Proprietary nozzle head limits ear tip choices
• Experienced a gentle roll-off in the upper midrange that removed some of the sweetness
• System matching depends on personal preference, but the product should not be used with ultra-linear gear nor amplifiers that heavily rely on negative feedback to bury the noise

Comparisons (according to reviewers)

• Versus the Sennheiser IE900, the MACH 80 had a clear opinion on the truth, showing the midrange that was missing from the IE900s' version
• Compared to the HIFIMAN Svanar, the MACH 80 is a more spacious-sounding IEM that adds more space between each note and the sound is more cohesive, closer to a real-life performance
• Compared to the HiBy Zeta, the MACH 80 has an even frequency response going with a reference tuning, while never sounding clinical or harsh
• Compared to the Westone MACH 70, the MACH 80 is the most linear offering of the Mach family, whereas the MACH 70 comes with a smoother and rounder response and offers a more musical approach
• While the MACH 80’s bass is considerably less in quantity than the FAudio Mezzo LE, it feels much more nimble

Takeaway: The Westone MACH 80 is an IEM that provides a balanced and accurate sound, great for audiophiles and professionals. The IEMs are lightweight, comfortable for long listening sessions, and great for hearing music the way it was meant to be heard.

Product Strengths

• Strong bass impact with plenty of energy in the low end, approaching dynamic driver performance.
• Clear vocal and treble performance.
• Wide soundstage.
• Highly detailed output sounds resolving even with low-powered sources.
• Comfortable and lightweight design.

Product Considerations

• Aesthetics and build quality may not be as impressive as other IEMs in its price range, the shell feels somewhat plasticky.
• The included cable is unbalanced (3.5mm) and could be more robust.
• The fit may cause fatigue after a while.
• Bass does not have much rumble.

Comparisons (according to reviewers)

• Vs BGVP DM9: The MACH 70 is a small but significant step up, with superior resolution, but the DM9 has tauter bass.
• Vs Campfire Audio Andromeda: The MACH 70 is better, with the Andromeda having great high-end detail but a metallic timbre and less low-end slam.
• Vs Sennheiser IE900: It is a pick-em, with the MACH 70 having superior resolution and low-level nuance, and the Sennheiser leading on purity of tone.
• Vs Westone Audio MACH 80: The MACH 70 is more V-shaped, while the MACH 80 is flatter and more reference-tuned, the MACH 70 is more sensitive and has bigger bass.

Takeaway: The MACH 70 is an engaging IEM with a bass-forward sound signature and clear highs, suitable for those who enjoy a dynamic and detailed listening experience. It is also easy to drive and comfortable to wear for extended periods.

Product Strengths

• Impressive technical performance, clarity, detail retrieval, and resolution due to its planar magnetic drivers.
• Features a new, comfortable, and ergonomic shell design that's also lightweight and durable.
• Includes two upgraded Time Stream Metal cables, providing both 3.5mm and 4.4mm terminations.
• Delivers a strong, extended bass response, with texture and speed, plus a nimble, airy top-end.
• Exhibits a spacious, wide, and holographic soundstage with good imaging and instrument separation.

Product Considerations

• Lower sensitivity might require a dedicated DAP or amplifier for optimal performance, and can sound anemic when paired with just a phone.
• Can be sensitive to source pairings, warmer DACs might wash out the mids and some pairings may bring out sibilance.
• Stock tips might not provide the best seal for everyone, and the stock tip selection is poor.
• Silicone eartips can make the treble sound harsh.
• The mirror-finished stainless steel faceplate is prone to fingerprints and smudges.

Comparisons (according to reviewers)

• Vs. Campfire Audio Bonneville: Astrolith has superior mids, clarity, detail and transparency, and better treble extension, articulation, and overall resolution.
• Vs 64 Audio Volür: Astrolith offers bigger bass and a more exciting presentation, as well as faster and more resolving sound, but Volür is more accurate overall.
• Vs. Oriolus Monachaa: Astrolith has a faster and more controlled bass with better texture, a more natural and realistic midrange with a fabulous timbre.
• Vs. Elysian Acoustic Labs Annihilator: Astrolith delivers a more robust and organic mid-range with realistic and natural timbre and more defined lower mids.

Takeaway: The Astrolith is a technically impressive IEM with a comfortable design that delivers a powerful and detailed sound. It could be a great pick for listeners who want high-end sound that can play all kinds of music well.

Product Strengths

• Captures the sound of the original Svanar, with a balanced tuning emphasizing bass and treble while maintaining the mids
• Incredible imaging performance, offering a wide, well-rounded, three-dimensional soundstage with excellent positioning and separation—highly competitive, even compared to non-TWS IEMs under $1000
• Has an R2R DAC which permits unreachable technical performance
• Very light and comfortable
• Excellent connectivity and usability

Product Considerations

• LDAC connectivity issues with invasive intermittence and noise cutting
• ANC and Transparency mode aren’t very useful and lack dynamic, delivering leaner dynamic, less musicality
• Plastic build might not be most durable if dropped
• High-frequencies are quite sensible to the source, making it one of the least forgiving TWS
• Hiss is also present

Comparisons (according to reviewers)

• The Svanar Wireless is punchier, with better bass detail and imaging, and a wider soundstage, while the Final ZE8000 has a warmer, more neutral sound
• The Svanar Wireless has stronger imaging performance, a wider soundstage, and a better balance between separation and cohesion
• The Svanar Wireless is superior in technicalities and tonal balance, as well as timbre and tone naturalness, and ultimately musicality
• The Svanar Wireless' soundstage is taller and wider but not as deep, since clarity isn’t as sharp and clean, silence being more "noisy"
• The Svanar Wireless has better sound and performs better technically
• The Sony TWS has bloated bass that overwhelms everything else; in comparison, the soundstage and treble performance of the Svanar Wireless is miles ahead, presenting a much more detailed, natural, and sophisticated kind of sound

Takeaway: The Svanar Wireless sounds impressive for wireless earbuds, and it has great connectivity and features. For those seeking high-end wireless sound, these are worth considering.
