Comfortable, long battery life, great for workout

I bought these a couple weeks ago and absolutely love them! I have historically sworn by the Apple Airpods, but these blow the Airpods out of the water. Battery life is (significantly) longer, bluetooth is never choppy, they're super comfortable in my ears (I use the smallest ear pieces they provide) and they're way more secure when I'm working out (running, lifting, circuit training). Oh and they're waterproof so I'm not stressed about sweat or water ruining them.
I would recommend this to a friend!

Got these a couple of weeks ago and use them all of the time. Great for working out and way more stable than my wife's airpods. Sound quality is very impressive for bluetooth. I highly recommend them.

First Investment Into True Wireless
on February 14, 2019
Posted by: Spencet33
from Kildare, Ireland
I am so happy I took the risk in getting these shipped to Ireland (Via a friend), it is my first venture into truely wireless earbuds and these don't disappoint. No issues with pairing to my Mighty Audio device or Phone, the sound quality is excellent and the balance is just right to bring the music to life. The bass is perfect and gives enough of a thump to get you in the zone for runs or workouts. The fit is perfect with these, they are lightweight, I didn't have to fix them back into my ear at any stage during any of my workouts and I even forgot I had them in at one stage. (Such a difference from constanly having to adjust my wired headphones). Highly recommended!

Excellent wireless buds for fitness enthusiasts.

[This review was collected as part of a promotion.] I have used many wireless ear buds, I workout a lot and I sweat too much at the gym. Enter JBL UnderArmour buds. I was skeptical before trying these buds. when I first opened the box, it looked premium. The charging case is sturdy, looked like it can withstand occasional droppings. The earbuds looks stylish with underarmour logo.
Positives :
* The fit is excellent
* The sound is amazing, especially the bass
* Talk thru and bionic hearing are cool features
* 20 + hours charging. ( thank god , cuz I am lazy to charge lol)
* Its really sweat proof
* Bluetoooth connection is solid with no droppings
Cons :
* The charging case is not much attractive
Finally, I will rcomend this product to all fitness freaks out there and they dont dissaopint.
I would recommend this to a friend!

A match made in fitness heaven

[This review was collected as part of a promotion.] A surprising Under Armour x JBL collab produces one of the best pair of user-friendly, active lifestyle earbuds!
Younger athletes at the gym pointed in my direction, saying “what are those?!” and they weren’t making fun of my shoes! Seriously, people were stopping me mid-workout asking about my wireless earbuds, especially when they saw me slide the metallic case open and remove them from the “drawer.” Speaking of the case, as soon as I touched it, I knew I was holding something special. Although it initially reminded me of a portable charger, the premium metal outer cover, sleek design, and unique mechanism put these above any other charging case I’ve seen. Advertised total listening time is 25 hours (5 hours for the earbuds plus 20 additional hours through the charging case), but I feel like it’s a little closer to 30!
I own 6 pairs of wireless earbuds and headphones, and these are very close to producing the best sound. The booming bass (does not drown out the mids and highs)adds that extra push to any workout. The responsiveness and clarity of sound was affected a little by the quality of the audio file. The bass really thumps without making my eardrums hurt, and I know I shouldn’t be surprised - these are JBLs after all - but I am truly impressed with the sound quality in such a small package. I played every genre of music I could think of on these, and all sounded great. I would also describe these as passive noise canceling - they work almost as well as a pair of protective earplugs! It’s worth noting there is a bit of a delay when viewing videos on portable devices, but not enough to ruin my workout. However, if you are considering buying these solely for media consumption, I would take the half second delay on videos into account. I watched movies on my iPad and streamed Netflix on the treadmill and the audio delay wasn’t enough to turn me off from the earbuds, but I’m hoping this is something that can be resolved in a firmware update.
Some describe the earbuds as “chunky,” but in the ear, they remind of a little volume nob (so I can turn my workouts up to a 10!). I found it really easy to grab them in-ear and make adjustments or take them in and out due to the shape. However, I could see smaller people, or those with small ear openings having a harder time adjusting to how “filling” these are in the ear. The “tips” that go in the ear canal are separate from the “wing” section of the earbuds that help lock them in the ear. There is a small, medium, and large version of each of the pieces in the box, making it easy to mix and match to create the perfect fit. I also enjoyed the little fitness-inspired design features (I see that barbell-inspired knurling around the outer edge!). And I know they probably don’t want to call them fully waterproof so that people don’t complain about mics not working as well when wet, or people shorting them out when trying to charge them soaked, but I swam and showered with them in and had no issues! These are perhaps the best fitness-focused headphones I’ve tried - and I’ve just about tried them all!
For what is worth: To look for a few cons(not many to be found), the Bionic hearing and talk through functions work, but not enough to distinguish the two features apart. It also felt like they were just reducing the music volume more than enhancing voices or the ambient sounds around me. I would enjoy improvement in these areas.
Overall, one of the best “sports” wireless earbuds/headphones currently on the market!
I would recommend this to a friend!

New fav pair of headphones
on January 14, 2019
Posted by: kch0725
from Boston, MA
These are my new favorite pair of headphones. I wanted a pair that had great sound quality, fit well/stayed snug for workouts, and also had great call quality. This pair checks all the boxes!
These fit perfectly in my small ears and are secure during my runs and HIIT workouts with lots of jumping. The sound quality is amazing and better than any other headphones I’ve tried.
The technology is also great - there’s an awesome feature where you can press a button on the left earpiece and it allows ambient noise in - so if you’re running you can hear cars, background noise and even have conversations with your running partner.
The storage case/charger is also so convenient. The case is small and lightweight, and chargers the earbuds automatically, which is awesome!
Would definitely recommend these to anyone.

Good product standard features

[This review was collected as part of a promotion.] I have used this for about two weeks, and I am enjoying this product. The earbuds are robust, light-weight. It takes time to get used to the clicks for different features. The ambient aware is really helpful for exterior runs. The earbuds sometimes face connection drops in crowded areas. Overall, it is a good product with some reliable features.
I would recommend this to a friend!
