UA Project Rock Earbuds – Review!

Product: Under Armour True Wireless Flash:

Everyone understands how beneficial music for training sessions can be, you likely also understand how some headphones just don’t cut it.

The Project Rock True Wireless Flash Earbuds are a pair of truly wireless earbuds by Under Armour from the Project Rock line, with the audio coming from the reputable brand, JBL. Allow me to give you a durability, performance and appearance rating.

Durability Rating:

I have had these earbuds for almost a year now, here are my thoughts:

Everything from the case to the product has been functioning optimally with no issues. The case opens and closes fine, the caribeaner is functioning as it should and it charges the earbuds without difficulty. The earbuds themselves have not seen a reduction in performance, which is great!

The charging life has been very similar to what it says on the box which is 25 hours (fully charged earbuds and case). I have not noticed any decrease in battery life.

The only flaw I have found with the durability of this product is that the case scratches somewhat easily. If you are careful you will have no problems, but sometimes we are not careful, and this case will scratch. You can just use the small plastic carrying case when going out to reduce the potential to scratch the charging case, however, you need to ensure the headphones are connected to your phone, and that you won’t need beyond 4-5 hours of battery life without a recharge.

All in all, my durability rating is 9.5/10. Everything is functioning optimally and there are no reasons to believe things will breakdown anytime soon. Like most products from the Project Rock line, they are made with quality in mind! Let’s jump into the performance rating!

Performance Rating:

Let’s first talk about how sleek this product is. With the small and truly wireless earbuds that can be transported in a low profile plastic carrying case, this product certainly does not take up much space. Even when in the charging case, it is still an overall low-profile product.

As for its connectivity, I have not had any problems. VERY occasionally they will take a little time to connect, but this is a rare occurrence and they stay connected the whole time during use. They pair together with the phone almost instantaneously and never disconnect unless you get out of range, which is about 30 feet or so.

The sound quality of these headphones is phenomenal. The base is absolutely insane while they have the right amount of volume power to meet just about anyone’s standards. To be honest, I was pleasantly surprised by the sound quality and volume of this product, as that is typically an area that lacks with a truly wireless earbud.

By now, you can probably tell that these earbuds are meant for those who want a low profile headphone that functions great and has perfect sound quality. Click here to check them out on Under Armour’s website, or continue reading to learn more!

Let’s talk about battery life! When I first got these headphones, I went through 9-10 training sessions with them, while also using them in numerous other scenarios, and I did not have to recharge the battery case. Simply plug it in overnight and they’re good to go for another week to 10 days (at least for my schedule). I am truly impressed with the battery life of these headphones, as battery life is often exaggerated by companies.

When it comes to using these earbuds for training purposes, I have had zero issues. They have not once come out of my ears, whether I am performing powerlifting style movements, Olympic lifting or even plyometrics such as box jumps. I have also ran with these earbuds, and they stay snug in your ear, even when sweating! They may need a minor adjustment after a while, but they are very secure in your ear overall!

A Cool Feature and My Performance Rating:

Now let’s talk about a cool feature that these earbuds have. There are truly wireless earbuds on the market that allow you to play/pause, skip songs and activate tools like Siri all through the actual earbud(s). This product is no different, it does a great job of accomplishing these functions.

However, it has a super cool feature that no other truly wireless earbud has! This is bionic hearing, which is talk thru technology. This feature allows you to press the control button on the left earbud once, which automatically lowers the volume of your music and amplifies any outside noise or voice around you.

This allows you to have conversations without the need to turn off your headphones. Yes, that’s right, when talkative Ted tries to strike up a conversation, you can at least stay somewhat in the zone by not needing to turn off your music or take your earbuds out!

All in all, I give this product a perfect 10/10 on performance. This is saying something since I don’t throw perfect scores around lightly! The sleekness, impeccable connection, great audio, outstanding battery life and of course, the talk thru technology all work too perfectly and are far too cool for this product to not receive a perfect score in performance!

Appearance Rating:

When we are going to invest a significant amount of our hard-earned dollars into a product, it is ideal for the product to look great while we are using it!

We’ll start with the charging and carrying case. The charging case is made out of a flashy gold that has a matte finish. It has The Rocks signature bull logo and motto “Blood Sweat Respect” on the front. I personally love this. The low profile, black carrying case also has his logo on the outside with his motto on the inside. Both of these cases look fantastic and would make anyone proud to own this product!

Now onto the earbuds. They are black with his bull logo done in gold colouring on the outside button of each earbud. They have a nice knurl which adds great character to the product. I love the blacked-out look, with the gold logo tying everything in together to make the earbuds pop!

All in all, I give the appearance a 10/10 as well! Everything just looks too clean and streamlined with just the right amount of pop!

Concluding Remarks:

In my opinion, those who are athletic and want a great functioning product with perfect sound quality all while having a great product appearance is who these earbuds would suit best!

  1. I definitely subscribe to this theory, needing some tunes playing to keep me going as I work out, and this one has such a sleek gold look to it.

    The combined battery life and durability of the Under Armour True Wireless Flash makes it a ripper of a product and a must have.

    Your review is detail and provides a great sounding board for allowing us to take all factors into consideration, and I will use it to compare against other like products to finalise my decision.



  2. First thing I observed about  Under Armour True Wireless Flash is it’s sleek and sporty look. As I read your article, I was impressed with its battery life. The ones I am using now for almost a year would only last for a day. Before it would last for 3-5 days depending on its use. Though I am not athletic person, my work requires me to move around the building and holding a phone in my hand is really awkward that why I bought an earbuds for that purpose. I have to agree on this product outstanding feature. It is great too for a working environment wherein you can hear what’s happening around while listening to your music. Keeps you get going while working! Thanks for sharing infos you got in this product. Will surely check this out.

    • Hi there, this sounds like a product that may be beneficial for you! Thank you so much for checking out the article, I am very glad it was able to help you!

  3. Hi kohl, I agree with you that there’s need to have a wireless earphone on that enhances and boost morale while having a workout session. I like mountain running but i hate it when my earphone just kept on sliding out of my ears due to the movement of the wire. In true, I have heard about this under armour wireless earbud and I think it’s high time I got one for myself. Going by this review, they seem to be top notch and the cool feature of being able to take note of the environment without killing the music is unique and new. The pricing seems okay considering the performance and quality. I’d surely give it a try

    • Hi Tracy, it sounds like this product would be great for you! Thank you so much for checking out the article, I am glad it was able to give you beneficial information!

  4. This sounds like a perfect match for me…I’ve always ended up with one side of my earpiece not functioning due to breaks in the wires. With this wireless earbud not only will be saved of line breakage but dangling of the wires whenever I’m on the run. I like the gold colour of the Under Armour True Wireless Flash….it makes it look classic. 

    Sharing your personal experience on it has been helpful but would like to find out about the effect of long hours of contact with sweat. Does it affect it in any way? Thanks for the information.

    • Hi there, I am so glad you were able to benefit from my review! 

      So far, I have not noticed any implications from the sweat. They are rated to be sweat and waterproof at IPX-7, which means they are ok to take splashes of sweat/water, they just can not be immersed in it for longer than 30 minutes at a depth of no more than 1 metre.

      I hope this answers your question!

  5. I’m glad I found this review, it’s really helpful – thank you.  I didn’t even know that Under Armour was making headphones/earbuds, but it’s good to hear that they’re partnering with JBL.  My daughter has a JBL wireless speaker.  It’s tiny, and probably at the lowest end of their price range, but the sound quality is really impressive, so I’m not surprised that you found the same with the earbuds.  With other earbuds, I’ve always had issues with fit especially when working out; I was very happy to read your comments about that.  I’ve been thinking about springing for a nice set of earbuds, and based on your review, these are a top contender.  Thanks again.

  6. Hi, those are a beautiful set of earphones. I love that they are wireless and I love that gold case.  How long is the battery life for these?  How log does it take to charge these?  Is the sound quality worth the price? I like that I dont need too have the wires annoying me while I am working out and getting in my way. 

    • Hi Jake, I agree, they look great! The battery life with a full charge of the earbuds and case is supposed to be 25 hours. I am actually not sure about the charging time and I don’t see it listed on their website. I just plug mine in overnight and they are ready to go in the morning. I would say the tremendous sound quality is defintley worth the price! The true wireless aspect of these headphones is very, very awesome!

  7. I love JBL products! I have their wireless speaker and it actually is functioning great as my speaker system in my Subaru right now. But my partner and I have been researching wireless earbuds recently because we both do a lot of group calls on a weekly basis, some with video and some without. 25 hours seems to be plenty of charge time to always keep these headphones useful! 

    • Hey Tucker, JBL products certainly are very well known for their quality and great performance!

      I’m sure these headphones would work great for what you would be using them for. Another pair that I think would suit your needs perfectly are the AirPods. If you would like, you can check out my review of them by clicking here.

  8. I have to say, that is a lot of money for a pair of ear buds.  They would truly have to be amazing for me to get them!

    For my job we are allowed to listen to music with one ear bud in and the other ear free.  I wonder how they would do if you could only use one of them.

    However, this is the third review that I have checked out on your site and I think you do a fantastic job at selling your products.  I very much trust your opinion because of how detailed you are with everything.

    • Hi Annie, they are quite expensive. However, I feel the value certainly justifies the price!

      These earbuds wouldn’t be perfect for listening with only one as you may miss out on some of the functions that the button on the other earbud provides. Seeing as they are so easy to use and have very strong sound quality, they would still work great if only using one of them!

      I am glad you are able to trust the information I provide, that makes me very happy!

      Take care!
