What reviewers think
Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.
Product Strengths
- Highlight is the boosted, forward, impactful, thick, rumbly and textured bass, due to the well-implemented bone conduction driver, which adds a tactile sensation and sub-woofer like quality
- Unique and visually appealing design with hand-painted brass faceplates crafted by jewelers
- Upper mids and treble are well-executed, detailed, and airy, providing a good balance to the bass, as the electret driver contributes to top-end details
- Overall sound is fun and engaging, particularly for genres like EDM, hip-hop, rap, rock, and pop
- Wide soundstage works well with well-mastered or live tracks
Product Considerations
- Mids can be the weakest point, potentially sounding recessed and pushed back in the mix, particularly for some instruments and female vocals, because the V-shaped tuning can cause certain instruments to sound thin
- Weight and size of the shells, due to the brass faceplates, may be uncomfortable for those with smaller ears
- Potential congestion issues, as one reviewer wished it 'had a little bit more room to breathe'
- Bone conduction effectiveness varies by individual
Comparisons (according to reviewers)
- In terms of the aggressive BCD implementation, the closest is the Empire Ears ZE51B
- Compared to the Jomo Audio Nautilus, the Legion has better bass and better mids
- Compared to the Nightjar Acoustics Singularity, the Flip Ears Legion is more engaging and has a good amount of quality and quantity of sub bass, mid bass, and mids
Takeaway: The Flip Ears Legion is a well-tuned IEM that provides an engaging listening experience thanks to its enhanced bass, making it great for bass-heavy music genres. It could be a perfect endgame for those who love fun, contrasty, V-shaped sound signatures.
What are hifi reviews useful for? (1) Identifying products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've heard (this means they probably are legitimately great). (3) Identifying a product's attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we often discount what reviewers say because they heap praise on most products—and are often apprehensive about publishing strong criticism or comparisons between products. Further, they seldom have more than a few products on-hand, often relying on their memories to compare past products. Always listen for yourself.

Thieaudio
Monarch MKIII
999
/
Released
2023
At their times, the original Monarch and the Monarch MKII set new standards for best-in-class performance in the global IEM industry. Not only did it redefine the price-to-performance bracket, but it forever changed how IEM manufacturers engineer and tune IEM's. Keeping with the times, the Monarch has undergone another revision to revamp its technical and tonal performance.
Thieaudio is a hifi audio brand best known for headphones with IMPACT2 technology—an in-ear "subwoofer" using two dynamic drivers in an isobaric chamber to boost bass power while keeping frequency constant—and dedicated sound bores to achieve studio-monitor layering and separation. The brand has established a benchmark reputation among reviewers for top-tier tonality at its price tier
Expand Details
Our Summary
Product Strengths
- Offers excellent midrange resolution, highlighting subtle details in instruments
- Features a safe yet exciting U-shaped tuning suitable for all genres
- Presents a dynamic and exciting sound signature, clear vocal performances, and a resolving staging performance
- The included cable is of high quality and features interchangeable plugs
- Has great audio reproduction accuracy and consistent audio delivery
Product Considerations
- The upper treble may be a little exaggerated for some listeners
- The shell is larger than average for a universal IEM, which may cause fit issues for some
- Stock ear tips are just okay
- Bass resolution could be better
- Does not have an integrated microphone, so a standalone mic is needed to take calls
Comparisons (according to reviewers)
- Vs. Monarch MKII: The MKIII has increased richness in its midrange and an upper treble exaggeration, offering a slightly U-shaped signature compared to the MkII's balanced profile
- Vs. Symphonium Helios: MkIII's midbass body contrasts Helios' dipped lower mids, MkIII has better overall resolution, but a more exaggerated treble
- Vs. 64 Audio U4s: The MkIII is better tuned compared to the U4s, with the U4s having a thicker midrange and weightier timbre
- Vs. MOONDROP x Crinacle DUSK: The THIEAUDIO have a more detailed treble range
- Vs. MOONDROP Blessing 3: The THIEAUDIO have a more elevated bass range
- Vs. TRUTHEAR x Crinacle ZERO: RED: The THIEAUDIO do a better job blocking out external noise and leak less audio
Takeaway: The Monarch MKIII is a well-tuned IEM that is great for all kinds of music and has excellent technical performance. If one is looking for a high-end IEM with a versatile sound, this could be a great choice.

Sennheiser
IE 600
899
/
Released
2022
Simply beautiful sound, and the lengths Sennheiser will go to achieve it — that is the story of the IE 600. These in-ear devices not only reproduce the detail and emotion of a recording, they transcend it. Because each earphone is a masterpiece. From the hand-finished amorphous metal housing to high-end audio components developed and made by Sennheiser, everything is manufactured to the strictest tolerances.
Sennheiser pioneered the world's first open-back headphones with the HD 414 in 1968, which became the bestselling full-size headphone of all time, and later developed the HD 25, evolving from 1980s broadcast use to become the industry standard in DJ booths worldwide. The brand is known for unique engineering approaches, such as integrating high-voltage amplifiers directly into earcups with Carrara marble chassis in the HE 1, developing proprietary ring-radiator transducers and absorber technology to eliminate resonances, and creating the long-running MD 421 microphone that has remained in production since 1960.
Expand Details
Our Summary
Product Strengths
- Agreeable, natural sonic signature
- Sounds very good, feels tough, and comes with most of the accessories needed
- Precision-milled housings follow the company’s IE 900, IE 200, and IE 300 models, shape wise, and therefore comfort wise
- A well-engineered product that sounds excellent
- Measured performance closely aligns with a headphone preference curve, so it sounds excellent
Product Considerations
- Basic silicone eartips that don’t fit everyone
- The MMCX connector is an atypical version that will not work with most other cables
- The texture of the AMLOY-ZR01 finish is not everyone's favorite to wear
- Treble is a bit subdued with cymbals resolving reasonably well, but way behind the IE 900
- Stock tips that come with Sennheiser's earphones are poorly designed; the silicone lacks rigidity to the point of which it more often than not collapses against the ear when one inserts the IEMs, thus making a proper seal very difficult to achieve
Comparisons (according to reviewers)
- Vs IE 900: The easier-to-drive IE 900 have a tighter, less thumpy low end and a leaner midrange, which results in better separation between the two, and also in better midrange resolution and clarity
- Vs IE 900: The IE 900 also have a much superior (perceived) treble extension and resolution, and a much wider soundstage
- Vs Final E5000: The final E5000 offer fuller voices, more bass, but less treble than the IE 600, and a narrower stage
- Vs Meze ADVAR: The ADVAR's sound is taller than the IE 600, the latter has more width, and imaging is tight and well-produced in both IEMs, with the IE 600 edging out the ADVAR by the slightest of margins
Takeaway: The IE 600 is a great set of earphones that will appeal to listeners owing to their punchy tonality and is pretty much unparalleled in their class. With the IE 600, listeners get undistorted audio and great isolation, and durable materials that will always sound good.
