It's already pretty split into sections enough I think, but I don't really understand why someone would think or come to the impressino that only on-ear headphones are covered...You're right, they are in the OP. For some reason I was under the impression that the OP only covered on-ear headphones so I didn't even think to check. Might be worth splitting the sections up with headings for type, FWIW.
Thanks for the advice, I think I'm leaning towards the Momentums then. Anything about either the JVC HA-FXT90 or Alpha Delta AD01 that might push those ahead? Why are there always so many good options to choose from : P
If I order from Amazon, listen to them, and don't like the sound, is it possible to return headphones normally or do they give you a hard time about that?
I think the JVC are the best sounding of the three and possibly the most well built as well, offering comparable bass, but a less recessed midrange, though I think they might feature the most finnicky fit and the shallow insertion means they don't isolate quite as well
The Alpha Delta AD01 is very similar sounding to the JVC, maybe just a tad darker meaning it has less treble. It features a modular design though, which is a huge pro considering you can just replace the cable if it were to ever fail quite easily. It features a more conventional and medium insertion so the fit is a bit easier to deal with than the JVC.
Basically just read both of these reviews on the JVC and Alpha:
