Radius HP-NHL21 High Resolution Lightning In-Ear Headphones - Demo



Radius HP-NHL21 High Resolution Lightning In-Ear Headphones

Fresh from Japanese company Radius Acoustics comes the HP-NHL21 High-MFD System High Resolution Lightning In-Ear Headphones.  The HP-NHL21 has a Lightning connector for use with current Apple products to take the digital signal from the device and convert it to a pure analog signal for higher quality sound.  The HP-NHL21's built in DAC can handle files up to 24/48kHz using the free Radius NePLAYER App.  With an industry first 4-button remote system that include the standard volume up/down, track forward/back, and microphone/pause/play buttons.  But the 4th button is a preset EQ "on the fly" adjustment through the NePLAYER. This player also has surround sound settings and a 15-band manual equalizer. 

The Radius HP-NHL21 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.  However remember that using the NePLAYER allows you to create whatever sound you like with the EQ adjustments!  The HP-NHL21 Lightning In-Ear Headphone creates a great sense of space and soundstage as well.  We enjoyed these at Rocky Mountain Audio Fest in October 2016, so give these a try for yourself!
