Know before you buy
The HS1670SS is designed for high resolution and clarity. Thanks to the Myrinx dynamic driver and the rigid stainless steel chamber, you get a precise, detailed sound with an expansive soundstage that works well for both critical studio monitoring and everyday listening.
While the stainless steel and aluminum construction provides excellent durability and acoustic resonance, the HS1670SS is designed to be comfortable for extended listening sessions. The ergonomic shape ensures a secure fit, though they will feel more substantial in the ear than plastic-bodied monitors.
Yes, these monitors use a standard MMCX connector, allowing you to easily detach and replace the included silver-coated cable. This also gives you the flexibility to upgrade to balanced cables if your audio setup supports them.
No, the HS1670SS relies on passive noise isolation. By achieving a proper seal with the correct ear tips, the physical design of the in-ear monitors effectively blocks out ambient noise without the need for electronic processing.
With an impedance of 24Ω and a sensitivity of 110dB/mW, these monitors are quite efficient. You can drive them easily from most smartphones, laptops, or portable digital audio players without needing a powerful external amplifier.
The separated chamber design isolates the driver from the rest of the housing, which minimizes unwanted resonance and interference. This results in a cleaner, more refined sound with better separation between instruments.
