I also recommend the NuForce HEM6, if anyone is looking for a pair of universal IEMs that somewhat "approximate" the tuning of the NH. To my ears the HEM6 are actually "darker" and thus mellower-sounding in comparison to the NHs, but the HEM6 have more bass punch (when volume matched by ear). If interested, my HEM6 review is
HERE. Fair comparison or not, sound-wise the HEM6 do fall short of the NH's overall sense of enveloping space and texture. As such, the NH makes up for the few shortcomings I personally have with the HEM6 tuning. That said, I'm no less impressed with the HEM6. I feel Lucky to have first owned the HEM6 because it was what unexpectedly spawned my interest in the NH. As a result, I only feel Luckier today to have had the opportunity to form an opinion of the NH for myself. To each his or her own however, as it should be.
