JBL Endurance Peak 4 True Wireless Sport Earbuds with IP68 and TwistLock Fit

For workouts where a secure in-ear fit and resistance to water and dust matter, the JBL Endurance Peak 4 is built around a TwistLock ear hook and an IP68 rating. Adaptive noise cancelling can reduce distractions, while Smart Ambient helps you hear more of your surroundings. Want to keep your earbuds in for a run and still take a call? The six-microphone system is designed to make your voice clearer outdoors.

Tips for day-to-day use

The TwistLock design pairs JBL OvalTubes with liquid silicone ear hooks and memory wire. The hooks are described as adaptable to different sizes, which may help keep the earbuds in place during movement, fit is still personal, so the shape of the hooks and in-ear tips will matter to your comfort. For a workout that moves from a gym to a rainy outdoor route, the IP68 rating is intended to protect against water and dust, including sweat, rain, salt water and sand.

Noise control is adjustable rather than all-or-nothing. Four noise-sensing microphones support Adaptive Noise Cancelling, while Smart Ambient lets more outside sound through for awareness or conversation without removing the earbuds. The JBL Headphones app provides custom levels, workout presets for light, medium or intense activity, and sound personalization through Personi-fi 3.0. It also includes five Relax Mode sounds for winding down after exercise.

Why it’s worth it

The appeal is the combination of a sport-focused fit with features often useful beyond training. JBL Pure Bass comes from 10 mm dynamic drivers, and Spatial Sound is included for stereo listening. During an outdoor run, the six microphones—three per earbud—use beamforming to help capture your voice and reduce unwanted background noise. A wind-resistant design is also intended to limit distortion from air friction, which is relevant for calls outside, though it cannot guarantee the same call quality in every setting.

Battery life depends on the listening setup. JBL states up to 48 hours of total playback with ANC off, including the earbuds and charging case, with ANC on, the stated figure is 8 hours in the earbuds plus 24 hours from the case. A 10-minute charge is listed as providing four additional hours. Compared with simpler workout earbuds that focus mainly on playback and fit, the Peak 4 adds adjustable awareness, noise cancelling and app-based sound options. Those extras are useful if you expect to switch between exercise, calls and everyday listening.

Should you buy it?

It makes sense if you want sport-oriented earbuds that combine a stabilizing ear hook, an IP68 rating and controls for adjusting how much of the outside world you hear. They also suit someone who expects to use earbuds for calls as well as music, since voice pickup and wind reduction are part of the design. The app adds options for tuning sound and choosing activity modes, rather than leaving you with one fixed listening profile.

It might not be a great match if you want a compact, hook-free in-ear design, the ear hooks are a defining part of this model. Also keep the ANC setting in mind when comparing the advertised playback figures: the 48-hour total is specified with ANC off, while the listed total is lower with it on. Choose the Peak 4 for a workout-first fit with flexible listening features, a simpler pair may be a better fit if you do not need the hooks, ambient modes or app adjustments.
