Under Armour Project Rock Over-Ear Training Headphones – Black

Project Rock Over-Ear Training Headphones are tested and approved by Dwayne Johnson himself, built to help you grind harder—with Adaptive Noise Cancelling for ultimate focus, and a durable sweatproof construction.

Washable Supervent ear cushions stay dry, and UA Storm Super Grip provides maximum stability.

JBL Charged Sound is tuned to maximize motivation, and Bionic Hearing features TalkThru Technology for talking to training partners, and Ambient Aware Technology to hear surroundings.

Give voice assistants quick commands and customize your sound with the JBL app.

With up to 45-hours of playtime and a hardshell case there’s nothing that will hold you back.

In the spirit of good, real-world testing, I broke out my dumbbells and put on the Project Rock headphones. The IPX4 rating promises sweat-proofing. You’ll appreciate having the IP rating on the UA Project Rock alongside the removable, and therefore washable, ear cushions.

For the most part, the headphones stay put during my workout, except when I lie on my bench to do dumbbell presses, at which point they fall off my head. The only upsides of this are that auto play/pause detection pauses my audio, and that the headset only slips onto the bench, as opposed to flying off while doing something else.

Possibly the best feature in the My JBL Headphones app is customizable EQ settings, which you can draw in for yourself. This flexibility allows you to diverge from bass-focused frequency responses. Though, it’s very fun and amusing to tap “Activate The Rock,” the associated EQ profile basically masks a lot of the mids and highs. Fortunately, you can rescue it with an alternate EQ, or go ape with it and turn it up if you want even more bass.

Bluetooth 5.0 connects to the Under Armour Project Rock when you activate the slider on the right ear cup and hold it for two seconds. An icy blue light indicates through blinking that pairing mode has initiated, Project Rock also does a great job maintaining a steady connection. You could probably leave your phone in the locker room and hit the weights without a hitch—depending on how large the gym is, of course.

Battery Life

You get an impressive 41 hours and 13 minutes of battery life with the Project Rock. That figure is with ANC activated too, so you can block out the world for nearly two days straight. With a USB-C connection and the cable included in the box, a five-minute speed charge provides you 120 minutes of battery power. That’s enough time to charge it, while you brush your teeth and tie your shoes on the way to the gym or work.

Noise Cancelling

For the most part, noise canceling works best at attenuating low-pitched frequencies that repeat with little variation, like airplane din. The Project Rock headset focuses ANC efforts on low and midrange frequencies, complementing the passive isolation’s treble attenuation. You don’t get silence, but JBL has done a good job of quieting the environment across the audio spectrum.

JBL Headphones App

Out of the box and over the ears with Project Rock

Project Rock’s build is a sturdy, almost rubber-feeling plastic affair with hints of an internal metal framework. It’s clear special attention is being paid to ear cushions, which sport a vinyl and foam mesh covering. The Project Rock Over-Ear Training Headphones holds on tight, but stays fairly comfortable for over an hour when worn with glasses. The vinyl can get hot even without exercise, which is a bit weird for fitness headphones. I wonder why Under Armour and JBL did not use the mesh foam for the entire ear cushion, as we see with the AirPods Max. Vinyl and light padding comprise the headband, which doesn’t provide much stability.
