Frequently Asked Questions
🎧 What's the difference between the Day and Night earbuds?
🎧 What's the difference between the Day and Night earbuds?
Day Earbuds (with stems): Designed for active movement—running, gym, commuting. The stems provide a secure fit and easy handling. Perfect for when you're on the go.
Night Earbuds (without stems): Ultra-low profile design for sleeping, relaxing, or lying down. No stems means nothing pokes your ear when your head hits the pillow. Maximum comfort for rest.
Both pairs are included and work with the same charging case. Switch between them based on your activity.
👂 Will they fit if I have small ear canals?
👂 Will they fit if I have small ear canals?
Yes! The HZA™ Duo comes with 3 sizes of ear tips (S/M/L) for both the Day and Night earbuds. We designed them specifically for people with smaller ears who struggle with standard earbuds.
The Night earbuds (without stems) are especially popular with small-ear users because they're more compact and don't rely on bulk to stay in place.
🔒 Will they fall out during workouts or sleep?
🔒 Will they fall out during workouts or sleep?
Day Earbuds: Engineered with a secure-fit wing design that locks into your ear's natural contours. They stay put during running, jumping, HIIT workouts—we've tested them extensively.
Night Earbuds: The low-profile design actually helps them stay in place while sleeping because there's no stem to catch on your pillow. They nestle into your ear canal comfortably.
If one pair doesn't fit your activity perfectly, switch to the other—that's why we include both!
