Premium Sound with Tunable Versatility: 10mm DLC+PU Dual-Cavity Dynamic Driver + Interchangeable Nozzles
Powered by the proven 10mm dual-cavity dynamic driver featuring a Diamond-Like Carbon (DLC) dome and PU suspension, the Delci AE delivers exceptional clarity, deep sub-bass impact, textured low-end, and smooth, fatigue-free highs. The DLC ensures rigid, precise treble with sparkling detail and excellent resolution, while the PU adds warmth, richness, and atmospheric extension for punchy, controlled bass that feels visceral yet refined.
What truly sets the AE apart is the innovative detachable tuning nozzles (two interchangeable sets included):
-
Silver nozzles (pre-installed): Emphasize the original Delci's signature warm, organic, and musical tuning—deeper, more textured bass, thicker note weight, lush mids, and smoother, non-offensive treble for relaxed, immersive listening (very close to the OG Delci but with slight improvements in control and technicalities).
-
Gold nozzles: Introduce brighter energy, enhanced resolution, forward sparkle, airier presentation, greater transparency, macro-dynamics, and technical performance (better separation, staging, clarity, and treble extension) without harshness or excessive sibilance.
This dual-tuning system lets you switch between a cozy, bass-rich Harman-ish vibe (silver) and a more energetic, detailed profile (gold), making the Delci AE incredibly versatile across genres—from bass-heavy electronic, hip-hop, and gaming (where its imaging and separation shine) to vocal-focused tracks, acoustic, and rock.
The result is a warm-yet-clean signature with powerful, controlled bass, full-bodied mids, natural timbre, and refined treble—praised for musicality, fun factor.
Striking Silver Design & Ultra-Lightweight CNC Aluminum Build
Retaining the feather-light 5.3g per side comfort that made the original legendary, the Delci AE features a fresh, premium silver anodized finish on aviation-grade aluminum shells. Crafted via single-piece CNC machining, polishing, and anodizing, it offers elevated aesthetics, scratch-resistant durability, an elegant high-end look with no chipping or wear concerns, and an ergonomic shape for secure, all-day fit with strong passive isolation.
Upgraded Premium Cable & Expandable Performance
The included high-purity silver-plated copper cable (upgraded over the original) provides cleaner signal transmission, better clarity, and enhanced warmth to complement the driver's characteristics.
- 0.78mm 2-pin detachable connectors for easy aftermarket cable swaps and balanced upgrades.
- Available in 3.5mm single-ended (with some variants offering 4.4mm balanced options for even better dynamics and staging).

Comparing the Delci AE with the Original Delci
The KEFINE Delci and Delci AE share the same core foundation: lightweight (~5.3g per side) CNC-machined aviation aluminum shells, ultra-comfortable ergonomic design, and a proven 10mm dual-cavity dynamic driver with DLC dome and PU suspension for powerful, textured bass, clear mids, and smooth treble. The original Delci offers a warm, musical U-shaped tuning with rich, atmospheric bass, natural timbre, and fatigue-free listening.
The Delci AE builds on this as a refined evolution with key upgrades: a striking silver anodized finish, an upgraded silver-plated copper cable (often with balanced 4.4mm option), and most notably interchangeable tuning nozzles—silver for a warmer, thicker, more organic sound very close to the original (with slight improvements in control and technicalities), and gold for a brighter, airier, more energetic profile with enhanced resolution, transparency, sparkle, separation, and dynamics.
Overall, the AE provides greater versatility and marginal technical edges (better imaging, staging, and clarity, especially on gold nozzles), positioning it as an excellent sidegrade or tunable all-rounder—ideal for users wanting customization, gaming, or a bit more polish—while the original remains unbeatable for pure musicality on a tighter budget. Both deliver exceptional value in the sub-$70–$90 range, with the AE feeling like a thoughtful enhancement rather than a drastic overhaul.
Whether you're discovering the Chi-Fi scene, upgrading from the original Delci, or seeking a tunable all-rounder for music, gaming, or daily use, the KEFINE Delci AE x Angel Ears collaboration edition delivers refined performance, customizable sound, premium build, and unbeatable musical enjoyment in a lightweight, durable package.
