QuietCore Microbuds are built for the moments when normal earbuds are simply too bulky. Their ultra-small profile sits comfortably in the ear without pressure points, making them ideal for sleeping, long work sessions, or anyone who needs sound without distraction. With Bluetooth 5.3 stability and soft silicone seals, they stay secure while delivering clear audio at any volume.
Despite their size, they produce a warm, bass-rich sound that feels fuller than expected, paired with waterproof protection and a battery system that keeps up with your routine. Whether you're listening in bed, on a commute, or quietly at the office, QuietCore Microbuds give you private, comfortable listening without the irritation of traditional earbuds.

FAQs
Are these comfortable enough to sleep in?

The in-ear design with silicone tips helps keep them secure for light workouts, walks, and daily use.
How is the sound signature?
QuietCore Microbuds are tuned for warm, bass-forward listening with smooth mids and a clear, non-harsh top end.
Can I use them with both Android and iPhone?
Yes. Bluetooth 5.3 works with most modern smartphones, tablets, and laptops regardless of platform.
Are they waterproof?
They carry an IPX5 rating, which means they can handle sweat and light rain, but should not be submerged in water.
