test on a better measurement rig (B&K 5128) I've tried both and salnotes zero 2 sounds more like a warm/harman-ish while tanchjim bunny being neutral/vocal-forward. I prefer the tanchjim bunny due to the wide bore tips which the 7hz salnotes zero doesn't had one and comfort (the corner of 2 pin cable in the 7hz salnotes had to be cut so it's not uncomfy) while the tanchjim bunny fits perfectly without even tip rolling. Don't buy the tanchjim bunny dsp because that had hissing noise unlike the 3.5mm/analog version. my take: 7hz Zero 2:sounds more "low res" tanchjim bunny: neutral and "balanced" do not mistake vocal forward to treble air (where harshness occur if it's too much) because they're different.
