In this video I review the brand-new Kefine Delci and compare it directly with some of the strongest single dynamic driver IEMs under $100: the Dunu Titan S, Moondrop Aria 2, TinHiFi T3 Plus, and Simgot EA500 (red filters). I go through the unboxing, build, cable quality, and fit, and then I focus on what really matters: the tuning and how it stacks up against the competition. Delci uses a 10 mm dynamic driver with a DLC + PU diaphragm, full metal shells, and a detachable 2-pin cable, and I have to admit the presentation is one of the best I’ve seen in this price bracket. Sound-wise, Delci is a warm and lush U-shaped IEM with a well-pronounced bass shelf, warm lower mids, relaxed upper mids, and a soft treble. It’s an easy listen with no harsh peaks, and if you’re sensitive to treble, it can be a safe choice. The stage is below average in width and depth, but imaging and separation are good for the price, and the overall presentation feels coherent. In comparisons, Delci comes across as the most rounded, coherent, and “balanced” option here if you love bass and want a non-fatiguing tuning without upper-mid glare. It’s not a detail monster, and I personally wanted a bit more air and sparkle, but after using it for over two weeks for music, gaming, and office work, I’m impressed—and it earned a spot on my best IEMs under $100 list for 2024.
