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

  • Small and lightweight design makes them comfortable for long listening sessions, even for sleeping.
  • Delivers a well-balanced bass quality.
  • Good sound with decent isolation using memory foam ear tips, with audio that is delivered consistently with a stable fit.

Product Considerations

  • Stock cable is of poor quality, tangles easily, and feels cheap, so reviewers recommend replacing it.
  • Recessed MMCX connectors make it difficult to find suitable replacement cables.
  • Stock ear tips often fail to provide a proper seal, leading to inconsistent bass response.
  • The 'dual tuning' bass adjustment feature via nozzle hole is considered a gimmick and can cause channel imbalance.

Comparisons (according to reviewers)

  • Vs IE 600: IE 200 has less treble and is less detailed, but the IE200 is smoother.
  • Vs Moondrop Kato: IE200 is smoother, lacks harshness, and has solid timbre, whereas the Kato can be aggressive.
  • IE 200 is better than the IE300 in terms of tuning.

Takeaway: The IE 200 is comfortable and has a good sound signature for a reasonable price. With a few upgrades like the cable and ear tips, the IE 200 could be a great option.

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.

Brand highlights

Taking a step back to look at reviewers' thoughts of the brand's entire lineup—not just this product—what stands out most is the following:

HD-559  

  • Positioning: Entry-level design focused on affordability and everyday listening needs.  
  • Description: Offers clear sound and comfortable design with a straightforward acoustic setup suitable for small rooms and casual music enjoyment. Compared to the HD-560S and HD-660S2, its basic performance and limited feature set make it a better fit for buyers with lower budgets and simple functionality needs.

HD-560S  

  • Positioning: Mid-tier model balancing cost and improved technical performance.  
  • Description: Delivers enhanced clarity and precision with a refined tuning approach that benefits home or studio use. When compared with the HD-559 and HD-660S2, it provides better sound detail while remaining accessible for buyers seeking moderate cost and practical functionality.

HD-660S2  

  • Positioning: Mid to high-level design crafted for a richer and fuller sound experience.  
  • Description: Offers a warmer sound signature with improved bass impact and a wider soundstage. Relative to the HD-560S and HD-800S, its technical enhancements and superior build quality justify the higher investment for users aiming for more refined performance without reaching the premium flagship tier.

HD-800 S  

  • Positioning: High-end open-back design intended for detailed, analytical listening applications.  
  • Description: Provides natural, transparent sound with a wide soundstage and precise imaging that benefits critical listening in controlled environments. Compared to the HD-660S2 and HD-820, it emphasizes technical accuracy and spatial detail.

HD-820  

  • Positioning: Premium closed-back design engineered for reference-class listening in isolated environments.  
  • Description: Features a unique closed-back design that merges open headphone sound characteristics with enhanced bass warmth and improved isolation, suited for quiet and nearfield environments. In comparison with the HD-800 S, it prioritizes sound isolation and versatility over the expansive open-air presentation.

Our take on the brand

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.

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.

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.

Expand Details

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.

Our Summary

Product Strengths

  • Excellent sound quality with depth, great soundstage, and crisp, clean elements
  • Active noise cancellation is a useful addition and blocks out rumbling and background chatter
  • The earbuds themselves are smaller compared to the previous version
  • Touch controls are responsive and easier to use than the old version, and customizable

Product Considerations

  • Continuous battery life with ANC on is quite short at around 4 hours
  • The case is not the smallest and can create a bulge in your pocket
  • Microphone sounds muffled
  • These do not support multi-connect, meaning that these cannot connect to a phone and a tablet simultaneously

Comparisons (according to reviewers)

  • Momentum 2's do not support multi-connect like the Jabra Elite 75T
  • AirPods Pro's transparent hearing quality is better than Momentum 2's
  • Sony's noise-cancelling has an edge over the Momentum True Wireless 2
  • Galaxy Buds Plus have great clarity, but the bass isn't as good as the Momentum 2's
  • The Momentum 2's sound better than AirPods
  • Momentum 2 is more comfortable and nicer to use, battery life is better, and noise-cancelling is included

Takeaway: The Momentum True Wireless 2 earbuds offer respectable noise cancelation, sound good, and are sweat-resistant. These could be worth buying if sound is the main priority.

Our Summary

Product Strengths

  • Versatile app with a good amount of customization, featuring a three-band equalizer or a dynamic visualizer interface
  • Respectable sound quality, with the ability to pick up on finer details going on in the background
  • Good battery life, offering around six to seven hours of use from a single charge with ANC active
  • Excellent pairing connectivity with Bluetooth 5.2

Product Considerations

  • Bulky and boxy design
  • Touch controls can be accidentally triggered
  • Plasticky and boxy case, which is not the most comfortable to fit in a pocket
  • ANC is not the most effective on the market in the low frequency range
  • Microphone quality is okay, not good for recording podcasts

Comparisons (according to reviewers)

  • CX Plus is in the same price range as OnePlus Buds Pro and Beats Studio Buds
  • Sony's ANC cancels more noise overall than CX Plus, but the Sennheiser has cleaner call quality in noisy places
  • The CX Plus adds ANC compared to the Sennheiser CX True Wireless
  • CX Plus offers better value than the Sennheiser Momentum True Wireless 3, especially if top-tier ANC isn't a necessity
  • CX Plus is a contender for Android users seeking an alternative to Apple AirPods Pro

Takeaway: The Sennheiser CX Plus True Wireless earbuds are a good choice if noise cancelling is desired in wireless earbuds, and good quality sound is sought. They have respectable audio quality with great ANC action, and fantastic battery life.

Our Summary

Product Strengths

- The case has an IP54 rating, and the earbuds have an IP55 rating for moisture and dust resistance

- Capacitive touch controls and tap controls (tapping the cheekbone) provide control options, even with gloves or beanies

Product Considerations

Our take on the brand

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.
