I'll describe the positive points first. These IEMs have exceptionally good build quality, with a thick cable that feels very sturdy and well made housings. The noise cancelling is likewise outstanding, particularly with the foam tips. The selection of accessories is excellent, with a range of tips and a sturdy soft-shell case.
Unfortunately, the product is compromised by two major flaws.
Firstly, the sound simply isn't what I'd consider acceptable for monitoring purposes. The bass is significantly boosted, bringing with it a resonant muddiness throughout the bass and lower mids. There is a real lack of clarity in the lower octaves, with sharp transients blurring into a boomy mess. Treble response rolls off significantly, giving a warm but slightly boxy character with a lack of air and presence.
Secondly, I just couldn't get a comfortable fit, for several reasons. The large housings were too big for my ears, with a sharp edge pressing into my outer ear. The angle of the nozzle compounded this issue. The memory metal sections of the cable do an excellent job of isolating cable noise, but interfered uncomfortably with the arms of my eyeglasses.
I don't wish to be too negative, as these IEMs may be a perfectly good choice for other users. The hyped sounic character may suit the preferences of some listeners who are less concerned with accuracy and detail. IEM fit is a personal matter, and what is painful for me may be perfectly comfortable for someone with larger or differently shaped ears.
