It only takes two hours to charge the case fully, though there is no speed charge feature – like with the Jaybird Tarah Pro, which can cram in a workout’s worth of battery in only a few minutes. Performance READ NEXT: Our favourite Bluetooth headphones JBL Under Armour True Wireless Flash review: Price and competition The Sennheiser Momentum True Wireless earbuds, by comparison, probably have superior audio, but include difficult and imprecise touch controls, when it would have been simpler to remove some from the equation.

Utilizing Bluetooth version 4.2 and supporting A2DP, AVRCP, and HFP Bluetooth profiles, these earphones ensure seamless wireless connectivity with various devices. They offer a range of up to 10 meters, allowing for freedom of movement without losing connection quality.The JBL Under Armour True Wireless Flash earphones are designed for active lifestyles and are built to withstand rigorous workouts. They are constructed with premium materials, ensuring durability and longevity. These earphones are also sweat and water-resistant, making them suitable for outdoor use.

There’s also a function button on the left-hand ear-cup to summon the preferred digital assistant on a mobile device, or toggle between the Everyday and Active ANC modes. While I appreciate the button being there, it would have been nice had it delivered a bit more functionality, such as the ability to toggle various EQ presets. The JBL Under Armour True Wireless Flash do hold some attraction. They’re the first water-resistant true wireless earphones I’ve seen from a major manufacturer and, for that, both JBL and Under Armour should be commended. I’m pleased that JBL has considered outdoor activities; however, personally I’ve had more use out of the dedicated Ambient mode. There are a couple of options to choose from: Ambient Aware pulls in all external noise to be heard alongside music; TalkThru lowers the volume and hones in on nearby conversations so you can engage in chit-chat without removing the headphones. In the effort to make the ear cushions comfortable, UA hasn’t forgotten about hygiene, either; these cushions can be removed and hand-washed. On the design front, UA clearly understands the needs of its users, and the only issue I had was a slight looseness around the ears when lying on a workout bench.Everyday is the go-to default, and it does a fine job of keeping unwanted noise at bay. It isn’t quite as powerful as the noise-cancelling on Sony’s premium headphones, but it extinguishes the gym radio to a barely audible hum. The Under Armour True Wireless feature Bluetooth 4.2 rather than the latest Bluetooth 5.0 standard, and there are occasions when the connection feels a bit patchy – though we never found it cut out entirely. Active mode is best saved for runs, retaining a degree of noise-cancelling whilst letting in some ambient sounds to establish awareness of surroundings. However, as a result of the proficiency of the other presets on offer, this isn’t a dealbreaker; but it does make me wonder how such an oversight could have occurred. After all, Dwayne Johnson’s involvement is all over the box and is the main attraction for anyone after a pair of gym-ready headphones.
