    1. Is that spike at 6kHz dependent on insertion depth? If so, does a foam tip dampen the response?

    2. The 3rd harmonic distortion products for 1kHz will be at 3kHz, where hearing is very sensitive. You did your measurement at 94 dB SPL, which is loud, but not THAT loud. Is this distortion readily noticeable with music?

    3. What does "Tone Platinum" mode sound like, subjectively, compared to the other two modes?

    4. It would be interesting to see how the others in the LG Tone series measure up, like the mid-priced Tone Ultra HBS-810. The old model HBS-800 had a response that was almost exactly on target at goldenears.net. Their target, at least. Of course they're using 1/3-octave smoothing, so there are probably a lot of warts that got hidden by the graphs. Also, the impulse response that they measured was pretty messed up (probably by the DSP). The other LG Tones use dynamic drivers, no? So they probably have better distortion performance.

      1. 6 kHz peak is movable. Thus, using a foam tip can be a good choice.
      2. It can be audible in some conditions, such as classical musics.
      3. It sounds more like V shape FR, with echo effect.
      4. Yeah I heard that other series use dynamic drivers. I'd like to try them as well.
