Just saw this response. By front chamber, do you mean the one coupled to ear canal or are there 2 chambers behind the driver? One to seal and one for connections etc. I get that any vent on the tip side would reduce bass and on the backside can increase it. I could see a lack of back pressure also being an issue with certain designs on insertion due to over excursion of a driver as well though likely rare.
I mean coupling to the ear canal, there is only one chamber behind the driver.... Yes you are right, vent on the tip side is useful in attempt to reduce pressure, occlusion effect, cable microphonics etc, and is normally associated to bass roll off....Anyhow, it might be a good thing from comfort point of view , however these front vents suits better for larger driver designs as they are easier to control and doesn't give that much bass roll off compered to smaller drivers... Regarding backside vent it is one of tuning parameters controlling the bass shape.

Great product, thanks! Too bad it doesn't appear to be bundled with sony phones anymore...
Yes, flat cables where fashion related at that time, and I would say these are the largest drawback in MH1 headset. If cable is not secured with a clip, they will eventually pull out the earpieces, especially left earpiece due some additional wight from the remote control. So, stiffness in MH1 flat cable is one nasty parameter, another one is cable area and surface structure as they will induce some cable microphonics.

I'm amazed at the research and engineering involved with producing this iem.
Was the target audience from the beginning the general consumer and not the so-called "hi-fi" seeking group?
I'm wondering because it is so conveniently priced.
I would have presumed that a device intended to be used with a smartphone would have its focus on functionality and comfort rather than audio quality.
Well, target audience where basically all smartphone users, looking for a great audio experience. Pricing, needs to be consumer friendly otherwise no one will buy it, especielly considering that market do not expect that kind great audio quality from a cheep headset. But i hope we can change that view a little bit.
