Here’s the honest truth about Under Armour headphones: Under Armour doesn’t build them — JBL does. Every pair of UA-branded headphones and earbuds was designed and engineered by JBL (Harman), with Under Armour contributing its sport-specific fabric technology and fit design. The partnership wound down a few years ago, which is why these are getting harder to find — but the remaining models are still some of the best-tuned workout audio you can buy, and several are still available on Amazon. After sorting through the full UA lineup, our top pick is the UA Sport Wireless React for runners, with the UA Sport Wireless Train taking the gym-headphone crown for lifters.

The UA × JBL Partnership, Explained
Before we get into the picks, a quick bit of context that most “best Under Armour headphones” roundups skip. Under Armour and JBL (owned by Harman) partnered around 2016 to build a line of sport audio gear: JBL handled the acoustics, Bluetooth engineering, and driver design, while Under Armour brought its textile know-how — breathable, washable, grip-lined fabrics — and athlete-tested fit design. The result was a genuinely good lineup with a distinct identity: workout-first tuning (bass-forward “JBL Charged Sound”), IPX water resistance, and TalkThru technology for chatting between sets.
That partnership has since wound down, and JBL folded its sport-audio efforts into its own Endurance line. That means most UA-branded models are no longer in active production — stock on Amazon comes from remaining inventory and third-party sellers, so availability shifts. The upside: the models you can still find are proven, athlete-tested designs that reviewers consistently praised, and several remain easy to get. Everything below is real, verified hardware — and where a model is hard to find, we say so outright.
1. UA Sport Wireless React — Best for Running

SoundMavericks verdict: The React is the pick we recommend most often for runners. It’s the lightest, simplest design in the UA lineup — in-ear buds with Sport Flex Fit tips and magnetic backs that clasp together around your neck when you’re not wearing them. There’s no neckband battery hump or bulky case to deal with, and the IPX7 Storm waterproofing means rain, sweat, and even a dunk won’t phase it. The 9-hour battery genuinely covers a full week of training runs on a single charge.
What sells it is the fit security. Between the winged ear tips and the lightweight aluminum buds, the React stays put through intervals and tempo work better than the bulkier True Wireless Flash, which some runners found fiddly. JBL’s Charged Sound tuning leans bass-forward — exactly what you want when your legs are dying at mile eight. Bionic Hearing with TalkThru lets you drop the volume and amplify speech to chat at a water stop or hear traffic, which matters for outdoor safety.
- Best for: runners who want a secure, no-fuss fit
- Water resistance: IPX7 (UA Storm waterproof)
- Battery: up to 9 hours per charge
- Standout features: Sport Flex Fit ear tips, magnetic buds, TalkThru, JBL Charged Sound
- Watch out for: no charging case — you charge via micro USB, so keep the cable in your gym bag
2. UA Sport Wireless Pivot — Best Secure Fit

SoundMavericks verdict: If earbuds tend to fall out of your ears, the Pivot is the UA model built for you. It’s essentially the React’s more tenacious sibling: same JBL-tuned sound and 9-hour battery, but with a behind-the-ear hook and Sport Flex Fit tips that lock the buds in place. For HIIT, box jumps, burpees, and anything with violent head movement, the Pivot is the most secure option Under Armour ever made.
Under the hood it’s proper JBL engineering — 5.8mm dynamic drivers with the same bass-forward Charged Sound tuning, IPX7 waterproofing with an aluminum-and-fabric build, and Bionic Hearing (TalkThru + Ambient Aware) for situational awareness. The behind-ear hooks add a touch of bulk versus the React, but for CrossFit-style workouts they’re worth it. Availability note: the Pivot is one of the harder UA models to find new — stock comes and goes through third-party sellers, so if you see it in stock, don’t wait around.
- Best for: HIIT, CrossFit, and anyone whose earbuds never stay put
- Water resistance: IPX7 (UA Stormproof)
- Battery: up to 9 hours per charge
- Standout features: behind-ear hooks, 5.8mm drivers, Bionic Hearing, 12-month MapMyRun Premium included
- Watch out for: hooks can press on glasses arms; stock is limited
3. UA True Wireless Flash — Best True Wireless Earbuds
SoundMavericks verdict: The True Wireless Flash was the flagship of the UA earbud line, and it’s still the most complete package if you want a true wireless form factor with the UA treatment. You get 5 hours per charge with 25 hours total from the aluminum charging case — the case itself is a tank, with a slide-out design that’s genuinely hard to damage. IPX7 waterproofing, TalkThru, and Ambient Aware all carry over from the sport line.
Sound-wise, reviewers consistently praised the Flash for bold, energetic sound with deep bass that suits workout playlists, plus genuinely good passive isolation from the Sport Flex Fit tips. The trade-offs: the case is bulky by modern standards, and there’s no active noise cancelling — isolation is passive only. It’s also one of the models most affected by the partnership wind-down, so you’ll typically find it through third-party Amazon sellers rather than Prime-shipped stock. Check the listing carefully before buying.
- Best for: lifters and gym-goers who want true wireless with maximum durability
- Water resistance: IPX7
- Battery: 5 hours per charge, 25 hours total with case
- Standout features: aluminum charging case, Sport Flex Fit tips, TalkThru + Ambient Aware, 5.8mm drivers
- Watch out for: bulky case; no ANC; availability is patchy — buy from reputable sellers only
4. UA Sport Wireless Train — Best for the Gym
SoundMavericks verdict: This is our pick for serious lifters, and it’s the most “Under Armour” product in the lineup — the on-ear design is wrapped in UA’s actual fabric technology: breathable SuperVent cushions that stay cool under load, and a grip material lining the headband and cushions that keeps the headphones stable through heavy sets. The cushions are removable and hand-washable, which is a genuinely thoughtful touch for something that lives in a gym bag.
The Train runs on big 40mm JBL drivers with a 16-hour battery and Speed Charge (five minutes on the charger gives an hour of playback), and the TalkThru button on the ear cup drops the music so you can talk to your training partner without taking the headphones off. It folds flat, includes a wired backup cable for dead-battery days, and can pair with two devices at once. The catch, again, is availability: new units are scarce, so you’ll mostly find renewed or third-party listings. If you want the definitive UA gym headphone, this is it — just buy carefully.
- Best for: weightlifting and gym sessions
- Water resistance: IPX4 (sweatproof)
- Battery: up to 16 hours; Speed Charge for quick top-ups
- Standout features: UA SuperVent + grip fabric, washable cushions, 40mm drivers, TalkThru, multipoint, wired backup cable
- Watch out for: on-ear fit can get warm on long cardio sessions; new stock is scarce

5. UA Project Rock Over-Ear Training Headphones — Best Premium Pick
SoundMavericks verdict: The Project Rock over-ear is the flagship of the entire UA × JBL partnership — co-developed with Dwayne Johnson’s Project Rock line — and it’s the only UA headphone with adaptive noise cancelling. It’s a genuine over-ear training headphone: 45 hours of battery with ANC off (35 with it on), IPX4 sweat resistance, washable fabric cushions, and full support in the JBL Headphones app with a customizable EQ (including a Rock-tuned preset).
This is the one to get if you want UA branding with flagship-level features: hands-free voice control, USB-C fast charging, an included aux cable for wired listening, and a rugged build that reviewers praised as genuinely gym-proof. It’s also the rarest of the bunch — the partnership’s highest-end product sold in the smallest numbers, so finding one new is difficult. Most listings today are renewed units or reseller stock. If you spot a reputable listing, it’s still an excellent headphone; just go in knowing it’s a legacy product.
- Best for: buyers who want the ultimate UA training headphone with ANC
- Noise control: adaptive noise cancelling + Ambient Aware
- Battery: up to 45 hours (ANC off), 35 hours (ANC on)
- Standout features: 40mm drivers, USB-C, JBL app EQ, washable cushions, aux cable included, Brahma Bull branding
- Watch out for: 294g is noticeable on long sessions; hardest UA model to find — expect renewed/reseller stock

How to Choose the Right UA Headphones
Pick your form factor first. Runners should lean toward the in-ear React or Pivot — lightweight, waterproof, and secure enough for road work. Lifters and gym regulars get more from the on-ear Train or the over-ear Project Rock, which stay put under a barbell and offer bigger drivers and longer battery. If you want true wireless buds with a case, the Flash is the pick.
Read the IP rating, not the marketing. IPX7 (React, Pivot, Flash) means genuinely waterproof — sweat, rain, even submersion. IPX4 (Train, Project Rock) means sweat-resistant — fine for the gym, not for downpours. Our IPX4 vs IPX7 guide breaks down exactly what each rating survives, and our waterproof headphones roundup has more options if swimming or heavy rain is in the mix.
Buy from reputable sellers. Because the UA × JBL line is discontinued, Amazon listings skew toward third-party and renewed stock. Check seller ratings, confirm the listing is for a new (not “for parts”) unit, and be wary of prices that look too good — counterfeit sport audio is common. The JBL sound signature is worth noting too: every UA model uses JBL’s bass-forward “Charged Sound” tuning, which you can hear in modern form in our JBL Tune 720BT review.
What to Buy If Your UA Pick Is Out of Stock
The honest reality of shopping the UA line in 2026: stock is finite and shrinking. If the model you want isn’t available from a seller you trust, don’t chase a sketchy listing — the JBL engineering underneath these headphones lives on in JBL’s own sport lineup. JBL’s Endurance series (Endurance Race, Endurance Peak) inherited the core DNA of the UA partnership: waterproof builds, Twistlock-style secure fit, TalkThru and Ambient Aware, and the same bass-forward Charged Sound tuning that made the UA models great workout companions.
Our take: the UA models are worth buying while they’re available because the fabric tech and fit details are genuinely unique — washable cushions and grip-lined headbands aren’t things you’ll find on standard JBL models. But if a listing looks dubious (no reviews, a brand-new seller, stock photos only), walk away and buy the closest JBL Endurance equivalent instead. The sound will be familiar, the warranty will be real, and you’ll actually be able to return it if something goes wrong.
Frequently Asked Questions
Are Under Armour headphones made by JBL?
Yes. Under Armour partnered with JBL (part of Harman) to design and manufacture its headphone line. JBL handled the acoustics, drivers, and Bluetooth engineering, while Under Armour contributed sport-specific fit design and its fabric technologies (like the breathable, washable SuperVent cushions). Every UA-branded headphone is, in engineering terms, a JBL product.
Are Under Armour headphones still being made?
No — the UA × JBL partnership has wound down and the models are no longer in active production. Remaining stock on Amazon comes from leftover inventory, third-party sellers, and renewed units, so availability varies by model. The Sport Wireless React is currently the easiest to find new; the True Wireless Flash, Sport Wireless Train, and Project Rock over-ear are scarcer.
Which Under Armour headphones are best for running?
The UA Sport Wireless React is our top pick for runners: IPX7 waterproofing, a secure winged-tip fit, magnetic buds that clasp together when not in use, and a 9-hour battery. If your earbuds tend to fall out, step up to the UA Sport Wireless Pivot with its behind-ear hooks. If fit is a persistent problem, also check our best earbuds for small ears guide.
Do UA headphones work with both iPhone and Android?
Yes. All UA × JBL models use standard Bluetooth and pair with both iOS and Android (plus laptops and tablets). The on-ear Train even supports multipoint pairing with two devices at once. TalkThru, Ambient Aware, and the JBL Headphones app features (on supported models) work on both platforms.
What’s the difference between the True Wireless Flash and Flash X?
The Flash X is the upgraded version: battery jumps from 5 hours per charge (25 total) to 10 hours per charge (50 total), Bluetooth moves to 5.0, and the case is a tougher aluminum design. Both share IPX7 waterproofing, TalkThru, and JBL Charged Sound tuning. The Flash X is harder to find today, so the standard Flash is the more realistic buy.
Are UA headphones good for the gym compared to regular JBL headphones?
For pure gym use, the UA models have real advantages: sweat-oriented fit design, washable cushions (Train, Project Rock over-ear), and IPX7 waterproofing on the earbuds. Modern JBL sport models like the Endurance line inherited much of this DNA. If you specifically want the UA branding and fabric tech, the remaining stock is worth it — otherwise JBL’s current sport line is the natural successor.

I am the founder of Sound Mavericks, where I provide the polite truth about audio equipment. I started this site because consumer electronics reviews are often too technical. Instead of using a silent lab, I test headphones, earbuds, and Bluetooth speakers in the real world – like on a noisy subway or in a busy coffee shop.
To stay independent, I buy my own review units (mostly from the United States) rather than accepting free gifts from brands. Once I finish testing a product, I sell it locally to our community. My goal is to help you understand sound quality, active noise cancellation (ANC), and battery life without the marketing hype.
