Just got my Headroom Ms16 which are open earbuds. These really surprised me. They definitely have a bit of soundstage. I prefer them to my Monk Plus. These are slightly mid centric profile, they are definitely leaning towards bass and mids. I am really surprised they seem to have exceptional clarity and detail for a $7 open back earbuds. They have a spacey and airy sound. I would highly recommend these as an alternative to the Monk Plus. I personally bought the Monk Plus and never touched them after some sessions, just wasn't for me. These I think rival them pretty well. They are not the best per se, but at around $7 they definitely punch above their weight.
These are actually great for edm, funk, disco, and hip hop and specially rock. Several tracks that shine on these:
Baccara - Yes, sir I can boogie.
Jamiroquai - Starchild,
Maniac - Michael Sembello,
T.I. - How life changed.
Ice Cube - It was a good day.
MF Doom - Doomsday.
Bou Yah - Busy signal.
Drake - Passion fruit ( these shined in this). The Cranberries - Zombie ( These shined I incredibly ),
nightwish - wish master.
Overall I think these do scale with recordings. In some they're so crisp and clear and some are just a bit off, I think it might have to do with mixing. The only issue I found is in the mids, the mids sometimes can seem shouty and sometimes airy whispery and sometimes distant. Again I think this is per recording as in some songs they shine and some they feel off.
I would definitely recommend these as an alternative to the Monks Plus!!
P.S. for a bonus my favorite track: Pendulum - The Island pt. 1 actually sounded great. Usually that track sounds like sht on bright headphones, and sometimes isn't reproduced great in some others. These have great retrieval, for example was listening to Pendulum - FKA Twigs, these almost scared me since there are some sounds in the background that came through with great detail and I thought someone was knocking on something.
