Here is the full Monster Supertips review with piccies
I've tried every foam under the sun for a variety of reasons: primarily because my sensitive ears prefer soft, plush, and luxurious. Secondly, some foams have less an effect on music. My favourites outside of Monster's Supertips are the low density Shure yellow foams, but while they have a very minimal impact on sound, they get nasty (full of earwax and grease) quickly.
The Supertips have several advantages: they don't get nasty from earwax and body grease; their sound tube stretches all the way to the tip, so the foam doesn't close around the sound tube; and they tend to last a long time.
These aren't the same as the Supertips which have shipped till now with Monster's Turbine Pro earphones. They retain hybrid characteristics, but rather than silicon-sandwiched gel, the new foam material encloses a central silicon pole.
These tips are more comfortable than Shure's Olives, less abrasive to the inner ear, and almost on par with Comply's soft foams. They isolate less than either though and the Olives will last longer. But whereas Olives and Comply eartips tend to muck up the sound, the Monster Supertips keep the same pretty linear silicon sound. It isn't perfect of course: silicon is softer than acrylic and has some reverberation, but these are probably the best I've used among hybrid foams and I don't see that changing soon.
Would be great to get some more impressions/reviews of these up here.
