Let's get one thing out of the way right off the bat: 3D printed shells are not a bad thing. Yes, the ABS plastic may have some dismiss these as just another set of cheap plastic IEMs, but there is nothing cheap about the Campfire Audio Satsuma, or inexpensive at $199. I was not sure what to expect going in, having only read the press release, and even in hand, these were so light and small that they surely could not be any good, right?

Wrong. The 3D printing has allowed Campfire Audio to individually manufacture left and right channels that sound basically identical. It's right in line with the company's history of using different materials and experimenting with various techniques, and the deliberately shaped ABS acoustic chamber contributes significantly to the tuning here. It does not have to be large either, having a single rear-ported full-range balanced armature driver inside. The bottom line for you is that if you like a punchy bass, definitely look elsewhere. I hear the Campfire Audio Honeydew might be more for you. The Satsuma's strength lies in its detailed upper mids and treble response, so much so that I forgot these might have been getting hot in the ears over time. Pop, jazz, rock, and R&B all work very well here, so this is the target audience that should be interested.

There are more technically competent IEMs in this price range, in terms of the employed driver system. The recently reviewed Ikko OH1S is one, which I wasn't particularly a fan of because of the similar tuning that isn't all to my liking and the inconsistency not only between the two channels of the same set, but also the same channels of different sets. I can't claim all the Satsuma IEMs will sound alike, but at least with 3D printing, Campfire Audio has a better shot at it. It is not going to look pretty, there are no color pigments or resin in play. There is not even a change in color from the all-orange shell unless you consider the steel spout for contrast, and the unboxing experience could be better with those unnecessary drawstring bags replaced. But for an ultra-low weight, comfortable, and well-tuned set of IEMs, you could do worse for the money.
