The seal offers excellent noise isolation, once you fit the correctly sized tips. Tonal balance is reasonably good and the use of redesigned 6mm milled drivers mean the Vista are noticeably more distortion free than past Jaybird sets I’ve tested.

Jaybird almost completely overhauled the Vista the second time around, making it even more durable than before. In fact, the Jaybird Vista 2 are the most resilient true wireless sports headphones on the market with their IP68 rating (the Vista was 'only' IPX7). Read more about it here: what are the best waterproof headphones for running? The most important thing with any wireless earbuds is how they fit — and that's even more true when it comes to workout earbuds. If they don't stay in your ears and you're bobbing and weaving, squatting and planking, then you're doomed. This is important as nothing is worse than worrying about buds falling out of your ears or getting soaked when you work out. The only thing workout headphones should do is to distract you from other people working out around you by blasting music in your ears; that's it. If I can feel the headphones in my ears, especially as they travel out of my ear canals, that'll make me lose focus.While ballistics are not typically part of most iron-distance events, many of the other aspects of the list above are a normal part of endurance sports training and racing. Which again, is probably why Jaybird units are known to last a while. These sorts of certifications are often used in marketing (as is exactly the case here). But at the same time, passing even the bulk of these types of certifications requirements means enough engineering to not kill the device through any given test. And more importantly, these tend to have surprisingly similar overlap to sports, especially endurance sports. control buttons on full wireless models usually require pressure to activate the button which jams the headphone deeper into your ear or use too-sensitive touch controls, while the wired between the ears models have a control box that doesn’t need to be jammed into the ear.

If you're looking for a pair of serious workout earbuds, the Jaybird Vista 2 are my winner. They have a more secure fit, and they are really rugged, so there's less chance of your sweat killing them. Their tiny charging case that comes with a lanyard is a nice bonus, too. Audio and connection quality for phone calls with these Jaybird headphones is very clear, responsive and also in stereo. I have experienced no lag at all while using these earbuds for phone calls. I know this because I received a rather annoying telemarketing call while out on a run! haha. Durability and Dirt/Waterproof rating It’s nice not worrying about accidentally damaging an earbud due to the rugid durability. Running with Jaybird wireless earbuds is a real pleasure due to the comfort in fit, and rich sound quality The Vista, Tarah and Tarah Pro offer the same waterproofing as the Vista 2, just without the dust resistance.Battery Life –Vista 2 now how less battery life (24 hours) than Vista due to the extra processing of the active noise canceling. If you take the app route to setting up, you’ll have access to some additional features you may want to have a play around with. The Jaybird app is available on Android and iOS and it’ll prompt you to connect the buds before letting you into the app. Inside you’ll find battery status for each bud and the case. You won’t find some noise-cancelling or ambient sound features here, like the Sennheiser Momentum True Wireless, which uses external microphones to play outside noise inside the drivers, keeping you more in tune to your surroundings. We’re told that Jaybird wouldn’t have been able to keep the dimensions down if it included these kinds of features, which holds true when we consider the bulkier earbuds of those other models. Our verdict Vista 2 wireless earbuds are ultra-lightweight and the shape of the earbuds offer a really secure in-ear fit when you use the correct silicone tip and wing to fit your ear perfectly. You’ll probably never worry about an earbud dropping out while running ever again.
