Coincidence indeed. I certainly like what it does with the bass. Aside from giving a great seal without a vacuum, the foam dampens the resonance from the occlusion so that the bass is really clean and doesn't intrude on the Lab 1's considerable acoustic ambience. (I think that this is why Complys are the default included tip with the Flat-4 Kaede, an IEM with powerful timbrous bass.)
I am particularly interested in your impressions of the LABs, especially considering you took a break for a few days from them. Tip rolling aside, how do you think/feel/enjoy/etc. their sound when compared to your other phones (including the VIs)?
I know you are taking your time with these, but I'm not a terribly patient HF'er. ;)
:-) Give me some time. I want to focus on rolling music instead of tips.
The Lab 1 is an obsessive IEM. I cannot take them out of my ears. I do like them very much. Getting a comfortable fit; getting the sound signature just right; figuring out what Takai-san intended; hold true to it or evolve... these are the issues/questions. It will take some more time.
I have decide that to figure out what is really going on, I have to allow myself to enjoy these instead of just testing them, i.e. listen to full albums in different genres. So far, so good.
I do have some thoughts already in relation to the Heaven VI but it is early days early. They are certainly both keepers. (Hint: M + both Lab 1 and Heaven VI looks to be a versatile and fine road rig.)
