How do these headphones balance audio quality with an open-ear design?

The AC228 uses 13mm dynamic drivers and directional audio engineering to focus sound toward your ear while reducing leakage. You’ll get balanced mids and highs appropriate for music, podcasts, and calls without isolating you from surroundings.

• 13mm drivers for richer tonal clarity and balanced output
• Directional sound path aims audio into the ear for better focus
• Open-ear format preserves environmental awareness and conversation ability

Are these comfortable and secure for exercise and long wear?

Yes — the AC228 clips use flexible nickel-titanium memory alloy and liquid-silicone contact points to adapt to different head and ear shapes. They are lightweight and designed to sit pressure-free so you can wear them for hours without discomfort.

• Flexible memory alloy frame conforms to fit and resists slipping
• Skin-friendly liquid silicone prevents irritation during extended wear
• Ergonomic, pressure-free design reduces fatigue on long outings

What wireless and durability features should I expect on the AC228?
