Check the review of OH1 from these brand sites
When the OH1 is queued for review I paired it with the M11 to let the drivers run in so it has at least 100+ hours play time with different music. The OH1 is quite sensitive to power and it is recommended to use stronger outputs for more balanced and controlled bass performance.
This design is very common for IEMs that utilized dynamic drivers. Thanks to the two vents, I did not experience any driver flex when wearing these IEMs.
Midrange performance was the only part of this headphone that changed drastically with a bit of burn-in. At first it sounded too thin with dry voices and weak textures. In 4 hours, midrange was already much better, with much more weight to it, voices gone deeper and sounded more natural.
