A Massdrop version of the Sennheiser HD700
Having had 2 home-run hits with the HD6XX and HD58X Jubilee, I'm hoping that Sennheiser and Massdrop can take some time to explore the possibility of a custom Massdrop version of the HD700. Even though I haven't had the opportunity to hear the HD700, I have a pretty good idea of what I'd like to see in a Massdrop version, based on owning the first two collaborated releases and hearing the HD800 as well. The HD700 really does appear to be the neglected middle-sibling that I think could get some much needed love with a few changes based on some opinions I've found while combing through reviews.
As seemingly typical of Massdrop, the first thing to change for sake of differentiation is to darken the colorway to a mostly matte-black finish, as I approximated in the poorly-edited photo I'm attaching to this post. It could definitely stand to look something like what Massdrop did with the Focal Elex, which I own and love.
Perhaps the model number could be HD 7X7, to avoid confusion with AKG's K7XX.
Build quality changes are the bulk of what I'd like to propose, and as I have yet to hear a stock HD700, I'll leave desired sound-signature changes for others to speak of (aside from what I hear is a general love or hate of the 5.5KHz peak and the 11Khz peak).
I'll start off with the headband. The rubberized top portion has been said to add a bit of unnecessary weight for some, and could probably be changed to plastic in order to lighten it a bit. This would also help with color consistency when going for the all-black look.
Next, perhaps a more robust click-adjust mechanism. I've read and watched many a review complaint about these being a little too light with the clicks (noticeably, Zeos of Z Reviews shaking the HD700 lightly and having them fall all the way to the lowest setting rather quickly).
Another point of dismay for several reviewers was the rather unwieldy 10-foot cable. As with previous Sennheiser collabs, this one could be cut from 10' to 6', terminated in 3.5mm with a 1/4" adapter instead of the monstrosity of its current stock form.
Otherwise it is apparently a pretty comfortable headphone, with many reviewers enjoying the ear-shaped pads. However, I think it's probably worth experimenting with an alternate material to see if that will yield positive sound-signature changes. Some modders out there have experimented with that, to varying levels of success.
Others, feel free to chime in about the sound-sig. I'm hoping this can be the humble start of some much needed love for a very polarizing and somewhat overlooked headphone.
