packing, The IEM’s delivery all amazing. loved it
Thank you Sir/ma’am for this product worth every penny on ears
Great sound quality for the price. The bass is punchy, vocals are clear, and overall audio feels well-balanced. The different sound modes in the app make listening more fun and customizable. Definitely a solid Type-C IEM option.
The Audiocular Spark DAC genuinely impressed me with its sound quality and power. The audio is clean, detailed, and well-balanced, with no noticeable noise or distortion. What really stands out is how powerful it is—driving demanding IEMs effortlessly without struggling or sounding thin. Volume headroom is excellent, and the overall listening experience feels punchy and controlled. For its size and price, this DAC delivers far more than expected and is a solid choice for anyone using power-hungry IEMs.
Pretty good and compact Dac at this price range.
Using the KEFINE Delci AE 4.4mm primarily for competitive FPS gaming, and it’s honestly outstanding for the price. The imaging is excellent — footsteps are easy to pinpoint, directional cues are very clear, and separation in busy scenes is impressive. This makes a real difference in games like PUBG, Valorant, and CS where positional audio matters.
The tuning feels very well-suited for competitive play: clean mids, controlled bass that doesn’t mask details, and crisp highs that help with awareness without being overwhelming. Paired with a balanced source, it has plenty of headroom and sounds very resolving.
For under $100, it’s hard to think of anything that comes close in terms of imaging and competitive performance. I’ve had no real complaints using it for long gaming sessions, and it delivers exactly what you’d want from a serious FPS-focused IEM.
If your priority is competitive gaming and positional accuracy, the Delci AE is an easy recommendation in this price range.
Good Sound Clear Trebles And solid build qualityfor the budget.
These are my 3rd pair of IEMs and can't say anything bad about these!
Excellent smooth and balanced sound stage with clear vocals, totally worth it!
Bought these as an upgrade to my iem stock cables, totally worth it!
Excellent build quality and improved sound stage 💯
Writing this review after almost two months of use, I can confidently say this IEM is amazing for the price. It arrived within three days and in perfect condition. Describing the product in such a short review is difficult, but in one line, the sound quality is impressive, though it may vary based on personal taste.
The bass is controlled (not boomy), with good clarity and a balanced V-shaped sound signature. It feels like I am in a mini theater :). I really like this IEM—my IEM journey starts here.
Kefine klean is one of the best iem is this price ❤️❤️💕
IEM reviewer eargasmic3060 recommended me as per my taste. I had asked for an IEM with ideal bass, neutral mids, decent detail on highs without sibilance. This IEM checked all the boxes. Very highly recommended for long non tiring listening. You shall customise your listening by tip rolling. Additionally, you shall choose nozzles based on your preference. This provides huge versatility. Overall, I'm very happy with the purchase. You shall go for it if you prefer neutral warm sound with decent highs without sibilance.
Awesome 👍😎

Liked the sound quality and loved the build quality
Moondrop audio devices consistently deliver their best performance when tuned to Moondrop’s own target response. If you purchase a Moondrop product, it is recommended to apply the same VDSF target EQ curve to achieve optimal sound quality and full performance potential.
