Product Strengths

• Offers two distinct tuning options via a switch, a balanced, clean signature (standard mode), and a bass-boosted signature (rumble mode), catering to different preferences and genres
• Upgraded build with a CNC-machined aluminum chassis provides a more premium feel compared to previous resin shells
• Great separation and detail retrieval in both modes
• Treble is sparkly with air and has great extension; the sound is smooth, detailed, and slightly airy

Product Considerations

• The stock cable is viewed as a downgrade compared to previous models, with a cheaper feel and aesthetic mismatch
• Its size is large for an IEM, which may cause discomfort or fitting issues for some users
• If treble-sensitive, caution is suggested as it might be too bright
• The provided case may be underwhelming given the product's price

Comparisons (according to reviewers)

• Vs Monarch MK3: The MKIV offers a more versatile experience due to the tuning switch, with a standard mode being faster and more detailed, it is warmer, but the low-end is richer
• Vs Campfire Audio Alien Brain: It is closer to neutral and balanced, while the Monarch MKIV has bent it into a slightly more V-shaped

Takeaway: The Monarch MKIV is a versatile IEM that is great for music listening and even competitive gaming. With its tuning options and detailed sound, it can cater to various preferences, making it a potential end-game IEM for many.

Product Strengths

• Impressive detail retrieval and resolution
• Balanced and well-tuned sound signature across bass, mids, and treble
• Excellent bass performance for a balanced armature IEM, with good speed and impact
• Smooth and natural midrange, especially for vocals and acoustic instruments
• Wide soundstage and good imaging

Product Considerations

• High price point puts it in competition with other strong contenders
• Large size may not fit smaller ears comfortably
• Bass, while good, may lack the texture and realism of dynamic driver bass
• Some reviewers found the sound slightly congested and lacking airiness
• Treble response may be too tame for those seeking a crispy and detailed sound

Comparisons (according to reviewers)

• Opinions vary with the 64 Audio U12t; some find that it has better bass texture and treble and is more refined, while others indicate the V16 is similar
• Some reviewers preferred the V16's bass and smoother sound compared to the Thieaudio Monarch MKII, while others liked the Monarch MKII's clarity and treble

Takeaway: The V16 Divinity offers very detailed sound and great balance across the frequencies. If one desires an all-BA IEM that handles many different kinds of music really well, this could be a solid choice.

Product Strengths

• The Valhalla is the best IEM that Thieaudio has made to date.
• It delivers endgame tuning with tasteful bass response, a sweet and clean midrange, and treble that feels airy and highly detailed.
• Midrange is perhaps the Valhalla’s biggest strength, with incredible detail, layering, and separation.
• The sound signature is very well balanced, offering a clean, highly cohesive, transparent and spacious delivery that’s also engaging and musical.
• The bass part has really solid low emphasis, with a wide soundstage, impressive sub-bass extension and clean emphasis on the sub-bass, while the mid-bass is more restrained but still delivers good thickness.

Product Considerations

• The cable design is not as emphatic with Vahalla, similar to the Origin cable, but it's not something new which should come with a flagship IEM.
• The unboxing experience feels no different from other Thieaudio products, and the accessories are almost the same that were shipped with the Origin, which is less than half the price of Valhalla.
• The shells are larger than typical IEMs, and the size may present a challenge, especially for those who have smaller earlobes.
• The puck-style carry case has limited space inside, making it hard to store the IEMs and the cable properly.

Comparisons (according to reviewers)

• Vs Origin: Valhalla offers a more natural reproduction of the music, and the bass is better, not by much, but it is better, with better quality bass.
• Vs Monarch MK3: The bass is better on the Valhalla, and the detail, the layering, the masking, the note weight, as well as the sibilance are also better.

Takeaway: The Thieaudio Valhalla is a high-end IEM that offers excellent sound quality across the board. For those who want a well-rounded IEM that delivers a detailed and engaging listening experience, the Valhalla is a great option.

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.
