Spear Labs nFORM™ XTR Series 500 Foam Ear Tips (2 Pairs) – Extreme Temperature Resistant
Experience uncompromising audio clarity and all-day comfort in any climate with the Spear Labs nFORM™ XTR Series 500 Foam Eartips. Featuring a distinctive signature purple finish, these next-generation anti-microbial nanocell foam ear tips are engineered for X-treme Temperature Resistance (XTR) and designed to fit in-ear monitors (IEMs) and earphones with 5mm and larger sound nozzles.
How Does nFORM™ XTR Technology Improve Comfort and Sound Quality?
Conventional memory foam ear tips often turn rock-hard in cold weather or overly mushy in high heat and humidity—breaking your acoustic seal and degrading bass response. Built with Spear Labs’ proprietary XTR formula, nFORM™ XTR Series 500 maintains consistent pliability across extreme temperature and humidity fluctuations. This creates a reliable, positive acoustic seal that blocks external noise and elevates sound quality anytime, anywhere.
