Hello, I'd like a recommendation on closed back headphones. I'm currently using an IEM, particularly the FLC8S, but I find that my ear wax is building up too much while using IEMs, therefore I'm looking for closed back headphones, primarily for office work. Comfort is a big priority for me, as I'll be using these for hours on end. I have a relatively small head, so the weight must be reasonable. I prefer sheepskin / leather pads, I'm willing to spend on aftermarket pads if I need it to increase the comfort. Efficiency is not an issue probably, I'm using Dragonfly Red to drive it from my Macbook Pro. Sound wise, could you provide a comparison against the FLC8S? I'm using Red+Black+Gold filters, which mean that the mids are forward, and subbass and low bass is at maximum configuration. I don't really know how to describe the sound ! Isolation should be quite ok, as long as its not that poor, since its already a closed back headphone, I assume isolation would always be good enough in general for office use. Budget is around USD700-750. Thanks a lot in advance.
