These are Lime Ears new Terra IEMs supports a 7mm titanium dynamic handling the sub notes. dual BA for Low-mid + dual BA mid to highs+RAU knowles BA for upper trebles. 4way crossovers. Apparently, this RAU knowles can perform up to 25Khz with no distortion. Basically is used a bit like ESTs. I was also told they modified it a bit to perform a bit similarly to ESTs.
Tuning is a reference U with a deep organic low hitting sub bass rumble and features some sparkly extended treble notes. Folks that love technical sets would do well with something like the Terras. It's all metal shells are classy and has enough room to house the 6 drivers inside. The shells are surprisingly light for an all metal build. Isolates decently too. Premium IEM in build and its sound is high class. Unlike the many Chifi IEMs with short nozzles these are the opposites with a decidedly longer nozzle.
I think if Geek Wold actually made a refined sounding IEM it would be something like Terras. Terras strengths are in its wide and immersive deep stage. Highly detailed nature, clean tonal character and excellent extension going both ways. Its mids while not forward in the mix are proper clean tonal and timbre characteristics. The sound is airy and definitely has a higher end sheen to the sound going on for IEM builds. Apparently, the gang at Lime Ears has been making high end IEMs since 2012. Company started in 2010. This particular IEM is priced at $1200ish and this is yet another compelling IEM in the highly competitive mid fi arena.
I know Lime Ears here has some stiff competition, especially at the upper mid fi level but these guys have the pedigree to be competitive. I have to admit I had no idea about these guys till I did some research. You will see some of the most respected headfiers all having a part in either owning or reviewing their wares in the past.
I would say 95% of my collection is either Chi fi or Asian made IEMs but hearing an IEM from a high end Polish maker was actually refreshing. Lol. Something a bit different but a bit familiar at the same time. These are a tweaked harmon tuned IEM with a bit extra in the sub bass and treble extension. The Chinese has more or less cornered the IEM market so it is very cool to see talented folks from other parts of the world who are passionate about their sound making very nice IEMs. I will have much more to say in my review but for now. It has been fun to get to know these.
I encourage you guys to look into Lime Ears and their IEMs. I know Emil the owner and founder of Lime Ears will be reading this and I want to send you a message. The thread you are reading has a whole lot of people reading it. This thread is about underdog companies that never got the big lime light that bigger manufacturers do. Its the whole foundation for the thread here hence the name "Discovery" Now that I know you can make high end IEMs. How's about making something that will be in the $200 range that will blow the doors off what the Chinese are doing? Because if you do. I guarantee your companies name will skyrocket to fame here on the discovery thread and naturally worldwide. Just a thought. Or maybe a challenge? Something to think about.
Thank you for kind words!
Haha, I loved how you used the term 'Polish-Fi' a while ago—what an analogy for Chi-Fi! It's interesting how Poland has such a rich audio tradition, especially for such a small country, and an exceptionally vibrant earphone scene. I have many friends in China that I’ve met over the years, and they are doing fantastic work! At the same time, it is sure we will have some differences in approach, which could be really fascinating for the audience!
When it comes to more budget-friendly products, believe me, something's brewing there! I still remember the earphones I bought for my Walkman; they cost $75 back then and were a serious upgrade from the stock ones. That was something that opened the doors to Hi-Fi for me! But it was, erm, like thirty years ago!
At the same time, my experience is such—at least the way It worked in our story—that first, products are created where costs don’t matter; only performance is what counts. It’s thanks to these that part of the experience and technology can later be used in things aimed at a wider audience. It’s like technologies developed at the edge of human capabilities, whether in space, military, or sports, that then transition into products with broader reach. And since we’ve already gained "some" experience...

But let's not rush the story; everything happens in its own time.
Some people who listen to Shocking Blue prefer this one over Venus.
I like these semi-utilitarian look of their shells with those zesty colourway on its faceplate.
Hah, thank you! Yeah, this faceplate can play such a peek-a-boo.

Like this calm plain aluminum from one side, and on the other side, bang, you get these amazing reflections, just pure spring garden! Kudos to the people that came up with this lab-grown-opals.
Amen to bringing the price down, like Dita did with the Project M and Elysian with the Pilgrim. Both of those companies struck GOLD with affordable IEMs when their history was kilobuck products. BTW Emil, gorgeous IEMs. Thumbs up!
Thank you, you know, sometimes I think of myself I'm kind of lazy dude by nature (or maybe the teachers told me so, and I partially believed), but this project took us by storm and we went above and beyond, first making black acrylic shells, later adding glitter to the acrylic, to come up with an idea of going to aluminum, redesigned everything, added opals, figured out how to cover them with reisin, yeah, it turned out more fun than expected.
