DN-12 "Spear" IEM is among DUNU's quality designed earphones. They keep the focus on the most vital thing when it pertains to paying attention to music: Balance. Bass is deep and present, the mids are clear throughout the entire variety of volume (from quiet late night to blasting on the subway), and the highs are airy with the presence you get out of an IEM.
Included in the DUNU DN-12 Spear accessory package: 2 Pairs of large nozzle ear suggestions, 3 Pairs of narrow nozzle ear suggestions, 1 Pair of biflange silicone ear suggestions (much better for efficiency) and1 Soft, synthetic-leather bring pouch (safeguards while not in use)
The technology relies upon a multilayer-membrane design that avoids undesirable vibrations that cause distortion. FRES patented technology makes the frequency response ULTRA large (highlighting the subsonic and high-frequency tones you thought you could not hear any longer). Recommendation: Try them with an audible frequency rang sweep and compare with some other phones or speakers. You'll hear more!
The technology and comfort of this headset matched together to make the sound quality and total effect of the Spear IEM a perfect match for any listening design.
