Radius HP-NHR31 High Resolution In-Ear Headphones

Radius HP-NHR31 High Resolution In-Ear Headphones

Fresh from Japanese company Radius Acoustics comes the HP-NHR31 High-MFD System High Resolution In-Ear Headphones with detachable MMCX cable.  The HP-NHR31 has a high Magnetic Force Driver system that allows for quicker transients, improved tonal quality, and increased sensitivity.  This techno babble translates to a fun, exciting sounding in-ear headphone.  Strong bass response and detailed overall sound with a warmer tone in the upper frequencies.  Great sense of space and soundstage for an in-ear headphone in this price range.  We enjoyed these at Rocky Mountain Audio Fest in October 2016, so give these a try for yourself!  What do you have to lose with our easy 30 day return guarantee.
