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.

Product Strengths

• Gorgeous design and fantastic build quality with premium materials, like titanium, aluminum, lambskin leather, and cowhide leather
• Extremely comfortable and lightweight (around 323-333 grams), with oval-shaped earcups suitable for larger ears for long listening periods
• Intuitive controls, including a mix of touch and physical controls, like responsive touchpads and tactile dials for precise volume and ANC adjustments
• Sound quality is well-balanced and versatile, making them suitable for various music genres, with particularly good performance for classical music, podcasts, and rock
• Amazing noise cancellation performance, effectively blocking out mid- and treble-range noises

Product Considerations

• Very high retail price
• Earcups are not very deep
• Not very portable due to a bulky design
• A heavier side, which can develop a little bit of strain on the back of the neck
• The Bang & Olufsen app does not work well, spending a long time trying to connect to the H95 most of the time

Comparisons (according to reviewers)

• Vs Focal Bathys: The Focal Bathys is cheaper and better in sound quality
• Vs Bose QC45s: The Bose QC45s are a little bit more effective in cancelling the high end of mid-range frequencies that you would get from a busy cafe
• Vs AirPods Max: The H95 manages to separate all the layers very beautifully, the AirPods Max is not on par
• Vs Bowers & Wilkins PX8: The PX8 is more muffled
• Vs Cambridge Audio P100: The P100 has more clarity and crisp sound to that treble without having that sibilance

Takeaway: If you want a luxurious pair of headphones with amazing build quality and very good noise cancellation, the Beoplay H95 could be a good option. The sound quality is great, and they are comfortable to wear for long listening sessions.

Product Strengths

• Excellent bass and treble response.
• Impressive dynamics and imaging.
• Has excellent treble extension.
• The Helios delivers an immensely deep-reaching sub-bass, accompanied by exceptionally clean articulate treble, with no overdone mid-bass to muddy things up.

Product Considerations

• Large angular shell that may be hard to fit.
• Needs a reasonably powerful source, because many dongles will not be able to run these.
• Midrange is somewhat mixed and quite pushed back.
• Some found the stock cable annoying to deal with.
• There is a lack of mid-bass.

Comparisons (according to reviewers)

• Vs Campfire Audio Andromeda 2020: Helios has a leaner sound and demands attention, sporting aggressive dynamics, sharper resolution, and BA bass that actually slams.
• Vs Hidition Viento-B: One can consider the Helios a Viento-B on steroids with more bass, a more balanced midrange, and a more linear, extended treble response.
• Vs Moondrop S8: The Helios clearly pulls ahead in its impactful dynamics and standout BA bass.
• Vs Sony IER-M9: The Helios has far better dynamics and a smoother, more airy treble response.
• Vs Thieaudio Monarch: The Helios has more treble extension and presence in those final octaves, and for technical performance outdoes the Monarch all around, particularly in the staging and imaging presentation.
• Vs Unique Melody MEST/MK2: The Helios doesn't make compromises, as it sports comparable resolution to the OG MEST and outclasses both IEMs in the dynamics department, and the Helios' treble is a step ahead of the ESTs being used in the MEST IEMs.

Takeaway: The Symphonium Helios is worth consideration for those seeking high-quality sound with great bass and clear highs. It is designed to sound good with diverse musical genres, so listeners can enjoy what they are hearing.

Product Strengths

• Wide soundstage, unusually large for a closed-back headphone
• Good mid-bass impact and punch
• Comfortable design, similar to the HE1000 series, despite being heavier
• Detailed sound, especially in the midrange
• Good imaging and separation of instruments

Product Considerations

• Isolation is not strong, described as not much better than an open-back
• Frequency response can be erratic, with peaks and dips, leading to a potentially wonky sound
• Some reviewers noted a shouty, honky, or hollow timbre in the midrange
• Treble can be crisp but potentially harsh or sibilant for some listeners
• Weight can become a comfort issue over longer listening sessions for some

Comparisons (according to reviewers)

• Versus Dan Clark Audio Stealth, the Audivina has a bigger soundstage
• Versus ZMF Atrium Closed, the Atrium Closed has a thicker, richer sound and better bass extension, while the Audivina has a larger soundstage; the Atrium Closed has a more natural midrange
• Versus HIFIMAN HE1000 Stealth, the Audivina has better midrange detail, but the HE1000 Stealth has a warmer and richer sound
• Versus HIFIMAN Arya, the Audivina is more balanced with a fuller midrange, and the Arya has a wider soundstage and is brighter
• Versus Meze Lyric, the Audivina has a wider soundstage, while the Lyric has stronger sub-bass performance

Takeaway: The Audivina is a unique closed-back headphone with a spacious soundstage and detailed sound, which makes for a great listening experience. If looking for something different from a traditional closed-back, this could be a good choice.

Product Strengths

• Ergonomically comfortable for long listening sessions, and has significantly improved from the earlier Helios model.
• The bass is exceptional in quality, it's tasteful, well-controlled and doesn't intrude into the mids or lower mids.
• The Crimson delivers above and beyond expectations if the fit and power requirements are met, demonstrating quality of drivers over quantity.
• Dynamics, soundstage, and resolution are at a flagship level, offering an immersive listening experience.
• The all BA configuration allows the bass to slam hard as some of the best dynamic driver IEMs out there.

Product Considerations

• The upper treble can be too bright and zingy, potentially causing listening fatigue, particularly on certain tracks and sources.
• The sealed, ventless design can create pressure buildup in the ear canals, leading to discomfort, especially during flights or long train rides.
• The Crimson requires a powerful source to perform at its best, and may sound bland if not adequately powered.
• The short nozzle and specific design may cause fit issues for some users, requiring experimentation with different ear tips for optimal fit and seal.
• The stock cable's ear hook is practically non-existent and not doing anyone any favors.

Comparisons (according to reviewers)

• Compared to the 64 Audio U12t, the Crimson is technically superior, particularly in bass and upper-midrange, but lacks venting for longer listening.
• Compared to the Elysian Diva, the Crimson has an edge in technical performance—particularly for a sense of sound stage.
• Compared to the Unique Melody MEST MKIII, the Crimson has much sharper sounding treble, and it has way more energy in the upper treble unlike the MKIII.

Takeaway: The Symphonium Crimson is an IEM that delivers exceptional sound quality and powerful bass despite having only 4 BA drivers, making it great for listeners that want to enjoy a highly detailed and immersive listening experience. For those seeking a unique and high-performing audio experience, the Crimson is worth considering.
