I bought these when they first were released. I was curious because I have a few other IEM's from Advanced (M4, Model 3, Evo X, and 747).
The ceramic housing is interesting, they look like those shiny "rocks" found in floating candle holders. They're initially cool-to-the-touch but warm up pretty quickly. The wrapped wire is thin but very plyable and quiet. I use them with the provided foam tips, which are okay but not as nice as Comply.
The sound is pleasant and not fatiguing, which I think is the aim of the tuning. I don't listen to a ton of podcasts but I did listen to some streaming sportscast and these smoothed out the low-quality streams. I've found more detailed IEM's like the M4 or Model 3 really accentuate the noise artifacts in highly compressed streams like TuneIn or Pandora.
These are fine for casual music listening, like on the bus or maybe while doing another activity. There isn't anything offensive about the sound, but nothing spectacular either. However for $22 this is a pretty good deal.
The normal direct price of $29 is a little to close to vastly superior wired Model 3 from Advanced ($40).
