JBL Endurance Run 3C USB-C (JBLENDURRUN3CPURAM) Sport Earbuds, IP65, Purple

The in-ear format keeps the JBL Endurance Run 3C USB-C close and ready for training, while its wired USB-C connection suits compatible phones, tablets and desktops. The purple earbuds pair JBL Pure Bass Sound with Hi-Res certified audio for music during a workout.

Three sizes of ear tips help you find a comfortable fit, and the flexible design gives you two ways to wear them.

Quick sizing guide

The included ear tips come in three sizes, so you can choose the fit that feels comfortable and helps create an ear seal. TwistLock technology is designed to keep the earbuds secure during movement, while FlipHook lets you wear them in-ear or positioned behind the ear. That flexibility is useful when you want to adjust how the headphones sit for a run, gym session or other fitness activity.

The 8 mm dynamic driver delivers JBL Pure Bass Sound, and three EQ presets let you tailor the audio: use the default setting, select Bass to emphasize the low end, or choose Vocal to bring the midrange forward. Magnetic earbuds make it easier to keep the buds together around your neck when they’re not in use.

Why it makes sense

For exercise, a wired USB-C setup keeps music and call controls on the cable rather than requiring you to handle the earbuds each time. The three-button remote and built-in microphone let you manage playback, adjust volume, switch EQ presets and take calls. IP65 dustproof and water-resistant construction is designed for indoor and outdoor workouts, including sessions where dust or sweat is part of the setting.

Customer feedback often highlights a comfortable, secure fit, including for people who find it difficult to keep other earbuds in place. Views on sound and reliability are more varied, and some customers report durability concerns. The fit options, cable-mounted controls and workout-focused design are the features to weigh most closely when choosing these headphones.
