I had wanted to get the Plus for quite a while, but two things keep me from doing so: their high price and the ugly cable that everyone complained about. But when I saw that both of those issues had been taken care of, I had no reason not to try them out. And I am glad I did.
Before the Plus, my Drop IEM collection was composed of the Nuforce EDC3, the Pinnacle PX, and the Planamic. Out of those, I liked the EDC3 the most, but I did find that it lacked some bottom-end and that it sounded a bit cold and unnatural. For me, the Plus resolves all of these issue, while being just as light and comfortable as the EDC3. These factors, in addition to the Plus offering better noise isolation than the other three I own (at least when coupled with Spinfit tips), makes it my favorite Drop IEM so far (I have yet to try the JVC IEM.)
But even when I like the Plus a lot, I still feel that it is not my endgame, even though I honestly hoped it would. Something is still missing. I am starting to realize that I will need to make a huge leap and start looking for options that cost three to four times as much for that missing 5 or 10% (Yes... It does look like I have fallen into the audiophile trap...) Out of the Drop catalog, the Noble and Zeus multi-driver offerings are my target now.
For its current discounted price, I do think the Plus is worth it. If you can afford it and are looking for IEM options within the Drop realm, I would recommend that you get these over the rest of models in the $200-and-under range.
Would recommend to a friend.
