i would greatly appreciate that. i just recently lost one of my iems and am in the market for a new pair. Layla is under consideration for me as well as others such as k10 1984 a12...
Here is a breakdown of what I listened to
Classical A&K 240 Layla was far more detailed especially in lower mids and bass (even bigger difference when using the EQ). Treble was nice on both.
String Quartet A&K 240 Layla was subtly more spacious sounding.
Female vocal A&K 240 The differences were not so obvious, treble and voice were pleasing on both. Bass was not as big a deal as classical
Latin Jazz MacBook Using the headphone output I listened to the Buena Vista Social Club (Youtube). The 16 Pro's sound OK, but the Layla sounds more spacious and more detailed.
Latin Jazz A&K 240 Same as above, (but from 16/44 file).
Hip Hop MacBook Bass was louder on the 16 Pro's and had more of a, "thump thump", quality than on the Layla's. Layla revealed more detail in the bass and lower mids but the effect was to diminish the loudness of the bass.
Heavy Metal MacBook Layla more detailed and spacious in the bass. 16's sounded muddy in comparison.
In summary, I would say it depends on what music you're listening to and what you're tying to achieve. If you are into clarity and details with larger ensembles then Layla is the way to go. If you're into solo vocal or instrumental without complex bass, then the 16's will be fine. For anything with complex bass where you want to hear the details, or for upscale sources with decent equalization then Layla is the way to go.
