Our take on the brand
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.

Product Considerations
