Good price on a solid product. Compared to the Flight S, it brings a fair bit more bass, and a bit more in the upper mids and treble (arguably a tiny bit more v-shaped, but not really), but the bass can be corrected with EQ and/or a future change in pads. Offers wired input (3.5mm jack), which is something that the Flight S lacks.
Unlikely to arrive before Christmas, so if you're happy to keep fishing, there's merit in waiting for Boxing Day deals from local stockists (notably JB).
For those who will ask in the comments: if you're looking for a genuine jump in detail and bluetooth functionality at the expense of battery life, check out the Audeze Penrose @ $400, otherwise: enjoy!
