Just bought these 1MORE Quad drivers in response to their $99 three-day sale ($199 list). I was looking for some every day IEMs, that I did not have to b e careful with (i.e. inexpensive) with Apple in-line remote that had better sound than my Apple In Ear Headphones, which are (or were) the Apple upgrade to the Ear Pods that they include with their iPhones.
Here are some impressions vs. the 1MORE Triple driver ($149 list), the Apple In-Ear earphones (the dual driver fully sealed ones, not the ones that come with your iPhone or iPod... $79), and the Sennheiser IE800 ($865 list on Amazon, more usually available new for $599, but now supplanted by the IE800S).
As with the Triples, the unboxing experience is wonderful, with a plastic-sealed sleeved box sliding open via a magnetic catch to show the headphones, a leather(-ette?) carrying case, a multiplicity of tips with sizes actually quantified in millimeters, and a 1/8" - to - 1/4" adapter. I have heard that 1MORE is as meticulous with their packaging and unboxing experience as Apple... I believe it!
I had gotten the 1MORE Triple drivers about a year ago in a similar sale for $99, but listened to them no longer than an hour before I determined they were not for me. The sound was too rolled off in the treble for me. I sold them within a day.
The 1MORE Quad drivers are brighter than I recall the Triple drivers as being... there is no dullness about the Quads.
Like the Sennheiser IE800, the cord has Kevlar multicolor threads, providing a subtle rainbow effect. Unlike the Sennheisers, these include a 3-button inline remote suited for the Apple iPhone and iPod (and I understand, Android devices as well).
The Apple in-ear headphones are brighter than the quads but have a greatly reduced soundstage and a bit less bass. They of course have a beautifully-functioning in-line remote, the indentation of which gives you better tactile orientation to the direction of the three buttons than does the quad.
The Sennheiser IE800 is just a bit less bright than the 1MORE Quads (i.e., 1MORE triple < Sennheiser IE800 < 1MORE Quad < Apple In Ear Headphones for brightness). Its bass is similar, and in fact the difference between the 1MORE Quad and the Sennheiser IE800 is much harder to perceive than between the Apple In Ear and the 1MORE Quad. I suspect that over time, I would prefer the IE800, as my initial impression of it was higher than of these Quads, but it is a small difference.
This was with only about 10 min of use on the 1MORE Quad, with all others being fully burned in. The Quads are bulkier in the ear than either the Apple or Sennheisers, perhaps making them a bit painful if you listen while lying on your ear (didn't try this.. just speculating, but it is a criterion for me).
I used my iPhone SE (like an iPhone 5S) as source, with Neville Mariner's Handel's Messiah, finale "Amen" as my music, listening to bass, to the bite (if any) of bow on string in the violin fugue perhaps 1 min in, and the surround effect of orchestra and chorus.
In short, these are well worth the $99, hard to distinguish from $599 IE800s (at least for this brief test), and have the advantages of three-button remote, sufficiently low replacement cost that you don't feel you have to baby them, and great looks and accessories.
