Even though the attack and decay of notes could have been resolved more quickly, they are on par with other IEMs. It's not a nuanced or filed down sound, but the treble has its own life and representation, not just serving the rest of the band.

I could say that the cable on the C3s, although I'm not a big fan of silver plating, is softer and more manageable. When it comes to technical capabilities, EW100P has an edge as it has average sound/speaker stage and better separation and layering. The resolution is also good, making it simple to approach macro details while finding enough interest in the micro details. As for its tonality and sonic profile, BLON Z300 is a warm, V-shaped sound signature with boosted bass, recessed midrange and just a slightly elevated treble region particularly on the upper-mids up to the presence part. Even so, there is a certain quality to trying to express and tease out some of the hidden mid-frequency detail that is eloquent and noteworthy.I'll be straight on this one, like its previous predecessors, it has a rather meagre technical performance. Founded in 2014, its catalogue includes the BL-03, a model that it has not yet been able to surpass. The treble of the z 4 is highly textured and it is possible to interfere with the treble level thanks to the replaceable filter. On instruments, Z300's also affects the tonal quality of instruments especially on strings like violins and guitars as they sound a bit too warm, buttery, austere and soft in my liking. And to talk about the midrange, I must say that the slow, meaty bass invades the midrange without mercy.

The lowest notes do not present as much rumble as on some other sets yet there is still more than enough for the track to be appreciated for what it is. The C3s are constructed of smooth, polished resin, weigh very little and have very high ergonomics, superior to the Z300s, which are slightly less well integrated and heavier.While the low end has similarities, the C3's bass is cleaner, slightly more visceral and better executed, with more resolution, definition, a cleaner and clearer punch, as well as a more discernible texture.
