Key features to look for in running headphones:

• Secure fit: ear hooks, wing tips, or snug in-ear tips keep buds from falling out during movement.
• Sweat and water resistance: look for IP ratings to handle sweat and light rain.
• Battery life and quick charging: choose a model that fits your typical run length.
• Safety options: transparency or open-ear designs let you hear traffic; use with awareness of local safety rules.
• Simple controls and stable Bluetooth make on-run adjustments easier.
