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
- Warm and smooth sound signature, described as 'silky' and 'buttery', leads to a fatigue-free listening experience, great for extended sessions
- Accurate timbre and natural, organic midrange makes it well-suited for vocal and acoustic-focused music
- Forgiving with poorly mastered or aggressive rock recordings
- Robust, impact-resistant Pelican case and a variety of ear tips (foam and silicone) provide a customized fit
- Linum SuperBaX cable is light, flexible and has low resistance, allowing for an uncolored sound, with the T2 connector being more robust than MMCX
Product Considerations
- Treble is often described as 'laid-back' or 'relaxed', leading to a darker overall tonality and potentially reduced detail retrieval or vibrancy in the high frequencies
- Soundstage is intimate or moderately narrow, stemming from the warm tonality and reserved treble
- Bass, while precise, lacks the 'thunderous impact' or 'tooth-rattling vibrations' of dynamic driver IEMs, and sub-bass extension may be limited
- Mid-range micro-detail could be better, and there is an upper-treble roll-off
Comparisons (according to reviewers)
- Vs Westone MACH 60: The MACH 60 has a more balanced sound with better detail retrieval and a more expansive soundstage, but the MACH 40 has a warmer tone and stronger bass focus
- Vs Dunu Studio SA6: The MACH 40 is less resolving, and has a less premium build than the Dunu Studio SA6
- Vs Campfire Audio Andromeda 2020: Better bass response, better defined upper mids, and more bass and mid details than the Campfire Audio Andromeda 2020
Takeaway: The Westone Audio MACH 40 is a comfortable and easy-to-listen-to IEM with a smooth, warm sound that is great for long listening sessions and forgiving of less-than-perfect recordings. It is a great choice for those who value accuracy and a non-fatiguing listening experience.
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.

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
- 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

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.
