Depending on your taste of course, this is my take away from a bunch of reading, haven't heard any of them yet but have spent some time with most of the phones they get compared to (HD280, HD650, AKG Q701, AKG K550, Momentum):
Most Neutral:
Sony MDR-7520
Focal Spirit Pro
A bit more/warm bass:
V-Moda M-100
Shure SRH-1540
Look for a used Audioquest Dragonfly to make your laptop less of an issue without sacrificing portability, then an HD650 is workable along with other phones that benefit tremendously from just a bit more juice than the typical laptop headphone jack. I don't think any headphone is ideal as a single reference for music production (maybe HD800 according to some, but not from a laptop...), but the above, along with the ATH-M50 would be a good place to start. I have the M-100 arriving any day now, and anxious to try the other three on my list as well. Bringing the HD-650 back into the fold in the next month or two. I have heard and dismissed: B&W P7 and Momentum due to comfort/fit problems, K550 due to slightly wonky mids/highs, HD280 and M50 just a bit too closed in for me... So I am looking forward to continuing my quest. I like a lot of genres and do a little recording/mixing/production for fun so I am hoping to find 2 or 3 that are long term keepers. I personally find the B&O Play H6 to be very comfy and good from a phone/laptop, but like the K550 not neutral enough if your priority is music production.
