Project Rock Over-Ear Training Headphones
- Understated, all-black aesthetic
- IPX4 rating
- Comfortable and breathable ear cushions
Look at the Project Rock headphones and there’s no mistaking that their use isn’t for any venue other than a gym. The all-black design coupled with the two bull icons on both ear-cups show they mean business. Without a discernible stylistic flourish, they’re not going to catch anyone’s attention on the street; but I really enjoy the overall aesthetic.

- Lots of variations for ANC and Ambient mode
- Disappointing ‘Project Rock’ equalizer
- Battery lasts for ages
If Under Armor can be thanked for the design, it’s clear JBL’s sound-engineering expertise drives the device’s feature set.
Active noise cancellation is present, and there are two modes to choose from: Everyday and Active. Active mode is best saved for runs, retaining a degree of noise-cancelling whilst letting in some ambient sounds to establish awareness of surroundings.
- Great overall sound quality that’s a pleasure to hear
- Vocals can get lost in bass-heavy songs
- Non-workout tracks fare just fine
So the build quality of these headphones is great, and the feature set – despite a few issues – is largely solid – but what about the Project Rock headphones’ sound quality? Well, given their intended use, let’s kick things off with one of my favourite workout tracks: Godzilla by Eminem.
