Tri StarLight
First IEM that really needed the least amount of tweaking (*EQ, added a smidge to the low shelf) on my part, for my preferred sound signature (an authoritative low end, with a relatively clean mid bass). Reading some of the reviews, I was concerned that I would have to dampen the 8khz range; but that didn't come to pass. In comparison, the Tri i3 (using same model cable & foam tips), sounded thin and bright, with the same settings on the MonoPrice THX DAC/Amp.
TLDR:
All around usage, not limited to a specific genre. Has an expansive sweet spot. Favors all of the vocalists that I could think to throw at 'em.
Admittedly, I don't do Heavy Metal, so that could be an outlier, as well as (one of my favorites) DanceHall Reggae, as the recordings are rarely of a high quality and a highly resolving set like the StarLight only highlights this.
Soundstage & detail
"Come Together", The Beatles: In the 1st 5 seconds, there's a rolling drum beat that clearly goes from center to right. The drums are really what highlight the detail. I can clearly distinguish between the kick drum and the distinctive lingering note of the snare.
"Wicked Game:, Chris Isaak: This is 3D. It's playing outside of the confines of my noggin: up, down, left, right. For a minute detail, that stands out, there's a constant drum brush that is near perfect.
"A Time to Say Goodbye" Sarah Brightman & Andrea Bocelli: You really are at a live performance, three rows deep, center stage.
"Blue Bayou", Roy Orbison: A very unique artist, with a three\four octave range. On other IEMs, his unique signature gargle/yodel (no idea what it's called) can get lost, not so on the StarLight.
"Ain't No Sunshine", Bill Withers: Vocals and most instruments are centered, but the violins have a perceived presence (width & height) well outside of the earphones.
Overall Playback
"Me and Mrs. Jones", Billy Paul: To use a catch phrase from that era, it's a panty dropper. Sooo sultry. The lower notes are just the right amount of thick and the vocals sound like a live performance
"House of the rising Sun", The Animals: There is a clear and discernable hiss, on every lyric that ends with an "s", in the 1st 30 seconds. I use this song as my measurement for sibilance. While still over pronounced, the Sssss are not fatiguing.
"Blue Bayou", Roy Orbison: A very unique vocalist, with 3-4 octave range; his full range is well represented
"Un-break My Heart", Tony Braxton's contralto voice (had to look this up), there are **lyrics where she hits so low and slow that it would be comical on a set with lower definition.
"I Will Always Love You", Dolly Parton: The clarity in details and overall presentation of the vocals are a clear demonstration that the StarLights can accurately hit the full vocal range.
Final thoughts:
If you look at the prior reviews, one thing becomes apparent, we all hear things differently. Some of the reviews found the upper bands to be a bit fatiguing or a set intended for "Trebleheads". For myself (someone who is hypersensitive to the 2khz - 4khz range), I wore the StarLights for well over an hour, without any fatigue. Two tangents that could attribute to the lack of needles in my ears, is my choice of a high purity copper cable and foam tips; but that's what I had on hand.
Diminishing returns: This is my third dip into this price tier, the other two being the original Dunu Zen and the FiiO FD7; while those two definitely were a notch up and were worth the purchase, the breadth, width and clarity of the Starlights make them worth a steady diet of beans and toast.
