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
- Excellent midrange tonality, note weight, and timbre, making vocals sound natural, clear, and vibrant
- Compact and lightweight stainless steel shell built with a unique design that fits most ear sizes comfortably
- Easy to drive, even on more affordable or older Android phones
Product Considerations
- Subdued and relaxed treble takes a backseat and lacks sparkle and shine
- Bass is adequate but soft and understated, not for bass enthusiasts
- Limited seal affects passive isolation during use, especially in louder environments
- Stock cable is a bit thin and may feel a bit low rent, considering how solid and nice the shells feel
Comparisons (according to reviewers)
- Vs Letshuoer SO-8: The DX1 has a much more neutral, mid-centric sound, compared to the warm, relaxing SO-8
- Vs Truthear Hexa: The Hexa sounds more balanced, more neutral, and overall more natural compared to the DX1
- Vs FiiO FD15: The FD15 offers more bass, particularly in the deep end, a darker, lusher midrange, and sweeter, more laid-back treble; the DX1 presents a more neutral yet slightly more aggressive tuning
Takeaway: The DX1 is a comfortable, well-built IEM with a focus on clear and natural vocals and mids, making it great for vocal-centric music and analytical listening. It is easy to drive and can be a good choice for those who prefer a neutral sound signature.
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.

Product Strengths
- Excellent build quality with a CNC titanium alloy material shell, giving it a premium feel
- Many reviews praise the natural and well-tuned midrange
- An airy and sparkly treble region that is not fatiguing or offensive
- The fit and comfort are excellent due to its smaller shell and ergonomic design
- The packaging and accessories are nice and extravagant, contributing to a premium unboxing experience
Product Considerations
- The bass response is underwhelming, lacking mid-bass emphasis and sub-bass authority, and may not satisfy bass enthusiasts
- The stock cable is often considered flimsy and not up to par for a flagship-level IEM, and lacks modularity
- The unique design of the faceplate may not appeal to everyone
- Some reviewers mention a lack of pneumatic pressure relief, leading to pressure buildup in the ear canal for some users
- Some dryness in the treble region
Comparisons (according to reviewers)
- Compared to Moondrop S8, the S8 does not have the same contrastiness, but offers more microcontrast and texturing in vocal content
- Compared to 7th Acoustic Supernova, the Supernova has better imaging performance and adds more mid-bass
- The Mystic 8 reminds reviewers of the Cadenza 4 (particularly the midrange)
- Vs Letshuoer Cadenza 12, the Cadenza 12 has more bass volume and depth, superior dynamics, imaging, and staging, but the Mystic 8 has more open mids
Takeaway: The Mystic 8 is a well-built IEM with a balanced and natural sound, making it great for critical listening and those who appreciate a mature and refined sound signature. Comfortable and technically proficient, it is a great choice for those who prioritize clarity and detail retrieval over emphasized bass.

Reviews
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

- 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

Sennheiser
IE 600

/
13
Reviews
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
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.

Truthear
Nova
169
/
Released
2023
NOVA is a 1DD+4BA in-ear headphone with 3-way crossover composite structure. Compared with HEXA, the original design intention is to further improve the high-frequency performance while maintaining a reasonable and efficient configuration, and also strive to bring users a mature earphone with a hybrid 3-way crossover structure at a reasonable price.
Truthear is a brand that has continued to design products not just in response to but in collaboration with the audio community and influential figures such as Headphones.com's 'Listener' and The Hangout's 'Crinacle'. Delivering products that achieve excellent adherence to preferred targets at extremely accessible prices.
Expand Details
Our Summary
Product Strengths
- Sound signature is likely to be palatable for a wide range of people at its price point.
- Good emphasis in the upper midrange, decent timbre, good resolution, the upper midrange is upfront with the vocals, nice details, and it works well with a smooth treble.
- Very smooth treble and the absence of sibilance.
- Good dynamic bass that's nicely textured and has a decent rumble.
- Imaging is accurate.
Product Considerations
- The Truth Ear Nova does not sound better or more balanced than the Hexa, since the reviewer prefers a more balanced sound signature.
- Nova is not a thick-sounding IEM, it's quite thin.
- The midrange is chiefly defined by a cavernous suckout in the low-midrange.
- Soundstage is a little narrower than preferred.
- Shell size may be slightly large for smaller ears.
Comparisons (according to reviewers)
- Vs. Moondrop Variations: Nova is significantly cheaper and close enough in performance that one should save money and go for Nova.
- Vs. Truthear Hexa: Nova easily has a smoother treble presentation, has more dynamic bass, and is more ergonomic, but Hexa has one of the best midranges in this price tier.
- Vs. Truthear Zero: RED: Zero: RED beats Nova almost across the board in tuning and simply sounds more normal.
Takeaway: The Truth Ear Nova is commendable for achieving its tuning at its price point, especially for those looking for a V-shaped presentation or Harman-esque kind of sound signature. If the Harman IE target is to one's liking, Nova is probably as safe a choice as any of the other Harman options out there.

Legacy 4
195
/
Released
2020
The Legacy 4 was designed concurrently with the Legacy 5 to provide a unique twist to the lineup. With the beloved budget model, the Legacy 3, and the natural and smooth sound signature of the Legacy 5 in mind, we wanted the Legacy 4 to be a middle ground - both in terms of the tuning and price.
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
- Great build quality and a generous accessory set
- Decently wide soundstage for closed-back IEMs, presenting a three-dimensional space for instrument placement
- Strong technical performance for the price, with standout resolution
Product Considerations
- The lack of a lip on the nozzle makes it impossible to use even slightly-larger-than-perfect eartips, as they just fall off
- Treble is a tad brighter than preferred, which some may find fatiguing over time
Comparisons (according to reviewers)
- Compared to the Thieaudio Legacy 3, the Legacy 4 has faster and more detailed bass, more detailed and extended treble, and better imaging and instrument separation
- Compared to the Moondrop KXXS, the Legacy 4 has a solid technical edge in resolution and imaging
Takeaway: The Thieaudio Legacy 4 is a competent earphone that offers a clean, clear rendition of music with excellent resolution and detail retrieval. It is enjoyable across various genres and provides a high-quality listening experience for audiophiles.

/
Released
2021
Thanks to the excellent designs and great sound, FiiO balanced armature and dynamic driver hybrid earphones have always been highly praised and become best sellers due to positive word-of-mouth. The all-new rookie FH5s is a true upgrade from the veteran FH5, with significant advancements and innovations in all aspects including appearance, comfort, sound quality. The student has now surpassed the master.
FiiO stands out for integrating unique features into portable audio devices, such as their BTR7 DAC/amplifier with its screen and wireless charging, and their KB3 mechanical keyboard with a built-in DAC/amp. The brand caters to audiophiles seeking personalization through products like their pioneering X7 music player with interchangeable amp modules and their compact R7 desktop system that combines streaming, DAC, and headphone amplification capabilities.
Expand Details
Our Summary
Product Strengths
- Detailed and clean sound, putting plenty of micro-details on the foreground
- Good build quality and comfortable design
- Swappable audio plugs included
- Tuning switches featured
- Open and wide soundstage
Product Considerations
- Treble can be a bit sharp and metallic sounding
- A dedicated DAP, Bluetooth dongle, or external DAC/Amp is needed to shine
- Below-average noise isolation due to its semi-open nature
Comparisons (according to reviewers)
- Approaches the FiiO FH7 closely, but is not exactly as punchy and engaging when bass notes are coming to play, FH7 has a better midrange rendition
- The FH5s gives a harder edge to treble notes, but at the same time creates a wider and more spacious soundstage
- The FiiO FD5 emphasizes warmth, smoothness, and a lush sound with prominent bass and midrange, where the FH5S has a more textured midrange, and a cleaner bass with less emphasis
Takeaway: The FiiO FH5S provides an outstanding unboxing experience and impressive features, along with a clear sound. The IEM allows for long listening sessions.
