Here's a brief comparison of the Moondrop Chaconnes vs the Shozy BK Stardust earbuds:
I'm using
@antdroid's suggestion of donut foams over the top of full foams on the Chaconnes. (My Shozy BKs are just using single donut foams.) I like
@antdroid's double-foam trick for the Chaconnes, but it still doesn't entirely resolve the fit issue for me. Here are some pros/cons of the Chaconnes:
Pros:
One of the best-sounding earbuds I've ever heard. In fact, I think I'd say it is my favorite-sounding earbud so far. Overall, I think I even prefer it to the Shozy BKs, which have otherwise been my favorites for years. They have a slightly more natural timbre to my ears and a smoother-sounding treble. (They don't have that hole that the Shozy BKs have around 8-9 kHz.)
Cons:
Even with double foams, they have a little less sub-bass than the Shozy BKs. One word of caution about these graphs though. I measured these using a 711 coupler with an earbud canal extender. My setup won't match your ears, and, very likely, neither would a full anthropometric set of artificial pinna. While I can get very repeatable measurements from IEMs, earbuds with any kind of foams are a bit of a crapshoot, because the bass can easily go up or down by several dB according to the amount of pressure you apply to the earbud over the canal opening, i.e., it will depend on your external ear shape and how well they sit and seal in your ears. I can get a decent amount of bass with the Chaconnes, but their ergonomics aren't nearly as good as that of the Shozy BKs. I can run around and do backflips with the BKs in, and they don't go anywhere. Just walking around in the Chaconnes is enough to cause them to wobble around and come loose in my ears.
So, my Shozy BKs will still be my go-to portable set of earbuds, but if you're going to be sitting fairly still, the Chaconnes are a great choice.
Somebody had asked
@ClieOS a few pages back for his top 10. Now I haven't heard anywhere near the number of earbuds that
@ClieOS has (I've only owned about 40 pairs), but the Chaconnes and the Shozy BKs are easily my top two. Number three on my top 10 doesn't even come close to the SQ of these two earbuds. Every other earbud I own, or have owned, has some fairly wild peaks or troughs in the FR, resulting (to my ears) in a less natural sound. These two are both way ahead of any other competition I've heard so far.
