Appearance: They are not nearly as gold as they appear on the website picture and are more of a dull silver/gunmetal (like a well circulated quarter/dime), which I much prefer. This picture is closer to how they actually appear:

Sound: I am new to this price/quality range of iems so I don't have much to compare to or an ear for the acoustic nuances that most of the reviewers here are able to pick up on and describe properly. My overall impression is that the detail is much better than anything else I've heard across a wide range of genres (funk, rock, edm, and classical so far) and I am easily able to distinguish or 'listen to' different instruments without them being distorted or overpowered by the other instruments/vocals. The bass isn't loud and muddy or annoyingly faint like it was on various Bose Klipsch (s4) and Shure iems I have used (not sure which models, for bose and shure but in the $70-$150 price range). These are easily the best sounding iems I have owned or used and I got a big fat grin when I first plugged them in and hit play.
Sources: So far I have used my iphone 6 (headphone jack) and my desktop computer (audio jack on the z170-a motherboard w/ Crystal Sound 3 and usb 3.0 port via the Turtle Beach Ear Force PX22 Headset Audio Controller)
. Most of my music listening has been on the iphone which sounds as I described above. The desktop audio jack I have only used for game/voice communication, but both those sound fine with no issues. The desktop usb port via the turtle beach audio controller has constant hiss/static sound that is especially annoying when the game/voice volume is turned down low. This hiss is not audible when I plug in my turtle beach headphones, skullcandy or RHA iems. I am not sure why this happens (maybe has to do with impedance/sensitivity?), but the Turtle Beach controller was probably primarily designed to match/function best with their headsets rather than act as a universal usb controller.
Fit Issues: The only real downside so far is that the silicone tips either don't fit comfortably or don't provide a good enough seal to remove outside noise. The bi-flange (right term?) ones scrunch up completely when inserted such that they provide less seal and insertion than the regular silicone tips (not sure if this is because of the material/design or them not being the right size for my ears). The more foam-like tips only come in two sizes and the smaller size is too big for me. When it's inserted deep enough to provide good isolation any movement of my jaw will pinch the end closed and mute the music almost completely if that makes sense. I placed an order for some small comply tips that will hopefully fix this issue.
Sorry for what I am sure is an extremely amateur review of these iems, but I figured I'd put something up here since I couldn't find much on the Tridents when I was initially deciding on which iems to go with and one of you might be in the same boat I was in a month ago.

Somewhat related...I'm interested in picking up a bluetooth microphone and remote since I will be using these primarily when I am walking/commuting to work. Does anyone here have any experience with the Noble BTS, and are there better options out there for <$100 ?
