About this deal
The Zero have less bass quantity, but the bass is cleaner and tighter. Transients, micro-details, soundstage, instrument separation, and clarity are better on the Zero. However, the Zero are harsher and more sibilant.
I’ve been heavily using the 7Hz Salnotes Zero for about a week and so far, it’s showing no signs of damage or wear whatsoever.In terms of timbre, there is no competition; the 7HZ Zero has achieved a better tuning in this aspect.
The soundstage is decently wide, though depth and height are below average. Micro-detailing, instrument separation, and clarity lose out to competitors. Imaging and layering are acceptable, though the intimate soundstage might make music congested, especially when it comes to fast or complex songs. I have been in the hobby for over 9 years now. Have owned or briefly auditioned (and given away to family/friends) a bunch of IEMs; E10c, Re-400a, Dunu Titan 1 (aka Fiio EX1), Beyerdynamic Byron, Audio Technica IM-70, Blon BL-03 and the Final E3000. The upper mids are well-dosed. It is at the edge of getting vocals forwards without veering too much to shoutiness. However, this region can be fatiguing at louder volumes ( Fletcher Munson curve), so the Wan’er are probably best used at low to moderate volumes. Treble The tuning is but far the highlight, and they got it spot on for a do-everything budget earphone that still bumps and sounds fun.The BL-03 are much more analogue-sounding, with inferior technicalities. The BL-03 perhaps have a more expansive soundstage, but the Zero best them in instrument separation, clarity, micro-details, and imaging.
