Elevate your listening with SpinFit Omni

SpinFit Omni for True Wireless Earbuds & IEMs offers replacement silicone eartips built around a patented spinnable 3D axis. This innovative axis bends to the natural angle of your ear canal, helping the eartips align with your ear for a tailored fit. The result is a seal that supports comfortable wear and directs sound along the canal’s path, delivering a more engaging listening experience without altering your device’s core performance.

Made from non-irritating silicone and SGS-certified after passing the OECD 439 Reconstructed Human Epidermis (RhE) test, SpinFit Omni combines comfort with safety. This certification signals a focus on material quality and skin-friendly use, making it suitable for extended listening sessions and everyday wear.

The Dual-Layer Tube Core and Triple-Segmented Core grip a variety of nozzle shapes securely, delivering a steady fit even during movement. This design helps the eartips stay in place as you commute, exercise, or simply enjoy a long-form listening session, while preserving a consistent sound delivery that respects your device’s original tuning.

Compatibility spans a broad range of popular earbuds, giving you a single upgrade option that fits many models. With a 3.7mm Eartip Tube Core diameter, SpinFit Omni fits nozzle diameters from 4.0 to 5.5 mm, covering models from Sony, InZone, XM4 and XM5, Beats Studio Buds+, Soundcore Liberty 5, Life A3i, Technics AZ100, JBL Tour Pro 3, Nothing Ear (1), CMF Buds 2 Plus, and more. This wide compatibility means you can confidently reuse the same eartips across several devices, simplifying upgrades and replacements.

What you may notice in daily use

In real-world listening, you may experience a more direct alignment of sound with your ear canal, potentially improving perceived coherence between the driver’s output and your ear’s geometry. Comfort is complemented by a secure fit that supports movement, whether you’re on a commute, working out, or relaxing at home. Individual results may vary based on ear anatomy and device compatibility.
