Anyway folks, recieved some info from the Aliexpress rep. More specs, graph and info on the upcoming Audiosense AQ7 here. Sorry they appear a bit small but u can double click and view it in enlarged view.
Hmm the vent filter hole thing is probably part of the tuning design, but not sure if it will let wind noise in and affect isolation? I had a set with a large vent (BLON Cardinal), and whenever wind blew parallel to it, the music would be swallowed by a whirlpool of whirling wind, otherwise when wind blew perpendicular to it, it was ok for isolation.
AQ7 looks V shaped and may be quite bassy from graphs. Not sure if upper mids will be hot. Good to see the stuff incorporated inside is of quite high quality eg Knowles BAs, resin shell etc.
The titanium DD thing may be interesting. The previous titanium DD sets I've tried had very fast bass speed and accuracy and extension, though they suffered a bit in the timbre department.
