Wired in-ear sports headset JBL Endurance Run 3C USB-C — intraaural, 20–40000 Hz, white/brown

Wired in-ear sports headset JBL Endurance Run 3C USB-C is designed for active use and connects via USB-C. Intraaural earbuds deliver a frequency response of 20–40000 Hz for clear reproduction of lows and highs. The lightweight construction (17.6 g) and secure wearing style with FlipHook™ and TwistLock™ technologies make these headphones suitable for workouts, running and daily commutes, while magnetic buds allow tidy storage around the neck when not in use.

Advantages

The FlipHook™ design lets you wear the earbuds in-ear or behind the ear for personal comfort, and TwistLock™ technology combined with soft ear tips provides a secure fit that resists falling out or causing discomfort. The IP65 rating offers dust protection and water resistance so the headphones withstand sweat and light splashes. Wired USB-C connectivity ensures compatibility with USB-C devices and delivers Hi-Res certified JBL Pure Bass sound. An in-line microphone with a 3-button remote and three EQ presets enables call handling and quick sound adjustments without accessing your device.

• Gym workouts and running
• Outdoor training in light rain or windy conditions

When it may not be suitable

The IP65 rating protects against dust and splashes but does not make them fully submersible, so they are not appropriate for swimming or prolonged exposure to heavy rain.
