Customer Reviews for JBL Endurance Race True Wireless Waterproof Active Sport Earbuds
[Microphone]: It's fine when used in quiet or not-so-busy areas but can't say the same about loud environments. The other side on the call struggled to hear me when I was outside and around a lot of background noise or on the bus.
Charging Case: It is a bit on the bulky and cheap side compared to my JBL Reflect Mini NC and Tune 115 TWS's cases. To put the size in a perspective, it is small in width but large in length and height. That was probably done in order for the earbuds to fit since they're shaped a bit differently and stick out of the ear more than other earbuds. The case is very lightweight but it doesn't feel high quality. The flip feels like it's going to snap in half and come out of its hinge when opening/closing the case. I also found it hard to open with one hand for convenience. The magnets and pins inside the case, however, snap the earbuds right into place and they start changing right away. There's an LED battery indicator on the charging case so you can see the charging process or how much charge the case has. However, the indicator is very small and it's hard to figure out exactly what percentage of battery the case is on. I definitely prefer LED dots over strip/horizontal indicators. The battery of the case is also not visible on the JBL Headphones app. So, it's a bit of a guessing game for the exact battery percentage of the case.
Battery life: By far, one of the best features of these earbuds. These do not die! The earbuds also fast charge so just in case you're able to kill them, you'll get the juice you need in minutes. Then, since these connect to the JBL Headphones app, you can see the battery percentage on each earbud. This comes in handy if you're using only one of them during your commute or working out, etc.
Side note: The orange USB Type-C charging cable that came in the box is very short.
On-earbud control buttons: I love that they are customizable in the JBL Headphones app. There are different presets you can assign to each earbud such as one touch on the right to stop the music and tap twice to go to the next track and the same with the left earbud. However, I would've liked it a lot better if each tap was customizable instead of the presets. So, the playback control preset just focuses on stopping the track, going next and previous. Then, the volume control preset specifically focuses on volume. It would've been more convenient if one, two, three taps, and tap & hold gestures were left to the user to decide instead of compromising in between different options. Also, the earbuds have a large surface area on the outside where the touch controls work and the battery is located. So, it takes a little bit to find the exact spot of the touch controls but it's easy once you get used to it. Other than that, having the app connection definitely plays a huge role in enhancing the earbud experience.
Fit: Although these are sports earbuds, they fit quite nicely and comfortably. It is the most comfortable earbuds I have owned from JBL (compared to Reflect Mini NC, Live 300 TWS, Tune 115 TWS). Every part of the earbuds that go in your ear is covered by rubbers (soft ear tips material). Naturally, they feel more comfortable than other earbuds that do not have that rubber/padding. I had no problems having these on for a long period of time. I found the earbuds to be more comfortable by taking off the extra hook that they come with. Because of the twistlock feature, the earbuds stay in their place tightly so the hook felt unnecessary for me. It also made the earbuds more comfortable. But, the earbuds come with only one enhancer that has a hook. Providing another enhancer with a smaller hook might have allowed a better fitting. I'm using the earbuds with the no-hook enhancer but would've loved to see how much of a difference a comfortable hook could've made. Lastly, although the earbuds seem bulky, they are very lightweight and don't hang down or feel like they are going to fall. But, I would've preferred a slimmer structure/fit like the Reflect Mini NC.
Ambient Aware & WalkThru: Ambient Aware function is actually very useful on public transportation such as NYC subways, and busses or when you're taking a walk/running around a busy area. It enables you to be "aware" of your surroundings by allowing more outside noise. I would've preferred more noise to be let in but they get the job done. On the other hand, I don't use WalkThru a lot. I just pause the content and listen what’s around so I didn't find WalkThru convenient because you just don't hear any of the content when it's turned on. You are better off just pausing the music than having this feature on.
Overall, these are well-designed, lightweight, long-lasting (battery), comfortable, waterproof earbuds that I would easily wear every day. There are a few features that can be added such as noise cancelation, adding more customization for on-earbud controls, or adjusting the outside look, but at this price range, I have no problems. I would recommend this pair.
Earbuds now are so technically advanced it is incredible and this pair is no exception. They pack a load of features:
JBL Sound, Secure Fit Twist lock, Dual Connect, IP67 rated, Smart Ambient Tec, Clear Call Mics and Multi Voice Assistant Ready….oh yeah one more thing, they work with the JBL Headphones App.
Opening the box is easy with just one security tab to cut. Minimal packaging, all recyclable, one notable improvement, neither the USB charging cable nor the extra ear cushions are in plastic bags. Kudos.
CONNECTIVITY Bluetooth 5.2 My Windows laptop and my Android phone both connected instantly. Google assistant was easy to set-up as well. I was hooked up and “OK Googling” in less than 10 minutes.
I have talked about twist lock and Dual Connect before. No surprises here, they are comfortable, stay in place and will work with one bud or both. With other earbuds I did prefer wearing just one while working or outdoors but with these I use both now because of….
SMART AMBIENT This function allows outside sound into the mix and has two settings. Ambient Aware: One can listen to music and still hear some of their surroundings. Traffic, for example. TalkThru: With this setting you can have a natural conversation without removing ones headphones. Wayloud quote, “Both of these settings work but can be overridden if you are listening to music way loud.”
IP67 WATERPROOF & DUSTPROOF. According to the manual these buds can sink into 1 meter of water for 30 minutes…I did not have the heart to fully test this claim. I do feel the need to prove they remain operational when wet. Some of you may remember my apple bobbing video, this time I showered with them in and rocking! I will spare you that video but they got wet and I am here to tell you, they still work.10
CLEAR CALL MICROPHONES That is correct microphones. There are four total mics on these two buds. Calls sound crystal clear and everyone I spoke to remarked about the clarity of my melodious voice. Another advantage of clear call is when talking to voice assistant. Texting by voice is actually advantageous when it understands the words I am saying…the first time.
SOUND These earbuds sound fantastic! Bass you can feel. Very articulate from bottom to top and they pass the Wayloud test. Yes. They can get way, way loud! A definite example of JBL sound.
The JBL Headphones app is pretty cool. You can control Smart Ambience, program how you want the buttons to function and there is a 10 band graphic equalizer. (Something I have been waiting for) There are several eq presets with space available for custom settings. While not necessary to use the buds, it is a great tool to make them sound the way you like and behave the way you need.
I like the way they look too. This is a great set of earbuds. Recommended by Wayloud.
