I haven't seen many people talk about this so I wanted to ask.

One of my main dislikes with earphones and IEMs is that when they fully plug your ear, all the noises in your body get enhanced by a ton. I'm talking about heartbeat, walking, talking, breathing or whenever you accidently touch the cable. I thought all in ears are like this that create a full seal until I got to try a pair of Airpods Pros. They feel like they are not in your ears, probably due to vents that let air in and out.

The only recommendation I've seen for IEMs that are similar are the 7hz Timeless. I was wondering if there are any others. Are there any other ones that don't create this pressure feeling?
