Enhance the sound quality and protect your earphones with AUDIOCULAR Grey IEM Nozzle Filters, precision acoustic dampers designed for universal and CIEM in-ear monitors. Available in three sizes — 4.2×2.7mm, 4.5×3.4mm, and 4.8×3.4mm — these filters feature a finely calibrated 100-micron acoustic mesh and premium grey non-woven material to smooth treble, control bass and midrange response, and reduce harshness without altering the original character of your earphones. Built for long-term use in humid environments, they resist dust, oil, and moisture while maintaining stable performance. Easy peel-and-stick installation and broad compatibility with dynamic, balanced armature, and hybrid drivers make this 10-pair pack an essential tuning and maintenance accessory for audiophiles, modders, and daily listeners alike.

Three Precision Sizes for Universal IEM Fit: AUDIOCULAR Grey IEM Filters are available in 4.2×2.7mm, 4.5×3.4mm, and 4.8×3.4mm sizes to match nearly all universal and CIEM nozzle designs. Compatible with popular brands like Shure, Moondrop, KZ, Truthear, and similar models, these precision IEM nozzle filters ensure accurate fit and consistent acoustic damping. The multi-size design reduces guesswork, making them ideal for replacements, tuning projects, and DIY modifications.

100-Micron Acoustic Mesh for Balanced Sound: Each AUDIOCULAR filter uses a finely tuned 100-micron acoustic mesh that regulates airflow between the nozzle and driver. This helps reduce treble sharpness, smooth sibilance, and improve bass control without muting details. Designed for natural tonal balance, these IEM acoustic dampers enhance clarity across bass, mids, and highs while maintaining the original character of your earphones during long listening sessions.

Premium Grey Non-Woven Filter Material: The grey non-woven synthetic material resists oil buildup, moisture, and fine dust far better than traditional paper filters. Ideal for Indian weather conditions, these dust-resistant IEM filters maintain stable acoustic performance over time. The neutral grey color hides dirt accumulation, while the strong adhesive backing ensures secure installation without leaving residue or damaging the nozzle surface.

Universal Nozzle Compatibility & Safe Design: Designed for 4–5mm nozzle diameters, AUDIOCULAR Grey Filters work seamlessly with dynamic driver, balanced armature, and hybrid IEMs. The non-conductive filter material is completely safe and does not interfere with impedance or driver performance. Perfect for audiophiles upgrading cables, adjusting tuning, or restoring clogged nozzles without risking internal components.

Anti-Resonance Tuning for Cleaner Audio: These grey nozzle filters help suppress unwanted resonance and turbulence inside the IEM nozzle, resulting in tighter low-end response, smoother treble extension, and improved soundstage perception. AUDIOCULAR acoustic dampers are ideal for transforming overly bright or thin-sounding IEMs into a more musical and balanced listening experience without permanent modifications.

Complete DIY Audiophile Filter Pack: Each pack includes 10 pairs of filters per selected size, making it suitable for multiple IEMs, long-term replacements, or repeated A/B tuning tests. AUDIOCULAR IEM filter accessories are perfect for hobbyists, reviewers, and modders looking to experiment with sound tuning at a low cost. Compact storage keeps filters organized and ready for use.
