Review 1: ★★★★★

“The battery holds a charge well, and the true wireless earbuds connect easily. The charger is short, but I have so many USB-C chargers already. There are many features that you should know about like power saving, and an option to locate them if nearby which can be useful. I don’t have any deterring things to say about this that would make me not want to buy these or be a deal breaker, I would buy them if I were looking for Bluetooth earbuds.”

Review 2: ★★★★★

“I have been impressed with JBL since they were known for very good bookshelf speakers back in the ’60s. So, when they bragged about the base response of these wireless earbuds, I just had to try them. They sound really good. These have the best base response of any earbuds I have ever tried.

The studio monitor headphones I normally use have a clearer response in the vocal range. But I was surprised that the JBLs actually trumped them slightly in the base range. And those headphones cost many times what these JBLs do. These come with three additional pairs of sealing tips to get the correct ear seal for the best fit and base response. They are a pain to change but once they are on, they are secure and won’t come off without serious effort. Look for the small index lug. It is there to make sure you get them oriented correctly. Make sure that you try more than one as they do make quite a difference. Once I got the right size, they are way more secure in my ears, don’t move at all and sounded better too.”

Review 3: ★★★☆☆

“When making comparisons, the JBL buds are harder to get out of their case, due to the weird geometry of the case, and my fingers keep inadvertently snapping the case shut when I try to take the wireless earbuds out. As soon as my fingers make contact with the earbuds, I activate one of the “gesture” controls (which in my case is play/stop) as they’ve already connected to my Bluetooth. They also don’t stay in my ears as securely as my AirPods. I’ve tried all the different ear pieces these ship with and they just don’t work for me.

What’s more, is these do NOT support wireless charging. It seems like such a small complaint, but currently, when we’ve all been spoiled by wireless chargers, watches, and phone cases, it seems like JBL should’ve just included this feature instead of the standard 3" cable that no one ever uses.”

Review 4: ★★☆☆☆

“The skeleton body is so cool. However, I feel that the earphones themselves are slightly larger. The holes in my ears have been expanded, and water now constantly collects in my ears when I take a bath.

Also, the true wireless earbuds that come with the standard earbuds are poor and difficult to remove, and when you put them back on, there is a gap between the earbuds and the earphone body, and this gets caught in the hole in the ear, so the discomfort is tremendous. The interchangeable wireless earbuds weren’t very good either. I think the sound quality is normal.”

Review 5: ★★★★★

“As with most of my “personal sound” devices from JBL, these are FANTASTIC. Sound quality is top notch with great low-end response in such a compact package! Everything is clear from music sound to call quality. Love these and would highly recommend them! Only knock is the same I have with most wireless earbuds, the peak volume could be a little more, but I’m sure they are set this way to protect your ears. Noise canceling functionality worked great the few times that I used it, very happy!”

Review 6: ★★★★★

“I found these to be a great all-around set of true wireless earbuds. Noise Cancelling worked great and the case was easy to use. Has a USB C connector for charging making it easy to keep topped off. Paired easily with my Bluetooth device and gave instant great audio without any tweaking. The best part is JBL is a recognizable brand name and has a good reputation to uphold lending itself to trusting this product.”

Review 7: ★★★★☆

“I’ve been a user of those old school wired earbuds for a long, long time and I’m just starting to dip my toes into the wireless Bluetooth market. I’ve owned a different cheaper pair of Bluetooth earbuds in the $30 price range that I’ve been using for about the past year, but those were for sound only (no call functionality) and the sound quality for music is not great. They lacked bass and music just didn’t sound pure. I will give them credit though, the part that went into the ear is comfortable and the controls are reliable and intuitive.”

Review 8: ★★★★☆

“Fast forward to these JBL earbuds. The sound quality difference is immediately apparent. I’m really happy with the sound quality on these wireless earbuds for music which is what I use earbuds for most. There’s nice bass and the music is clear. It’s night and day compared to my $30 wireless earbuds. I’m a little indifferent towards them as far as call quality is concerned. The people I talk to regularly tell me that they hear wind or that it’s difficult to hear me if I’m outside. If I’m inside and in a quiet environment they work well, but they aren’t a substitute for just holding the phone up to your head if you’re after max sound quality as far as I’m concerned. I’ve been able to hear people ok on my end with them, but they’re a little quieter than I’d like.”

Review 9: ★★★★★

“They have built in mics so you can use them to talk on your phone. The mics sounded really good when I recorded a soundbite with them. The pocket case recharges the wireless earbuds when you put them inside. That extends the batteries without having to find a wall outlet.

I have been listening to them for hours now. Overall, they sound great. If sound components don’t sound good, I don’t care what they cost or who made them. These really are a good value and worth every star.”

Review 10: ★☆☆☆☆

“The battery life is abysmal. The call quality is choppy. I can’t believe I paid so much for something with the same quality as a Daiso product, probably worse. And it was such a pain to return I had to keep it. Don’t waste your money like I did. Buy a no name brand for much lesser and a better quality.”

Based on the positive and critical user reviews, we can know that there are still some issues with these earbuds even though it has good sound quality and affordable price. This is because they are a bit big in size and the battery life is terrible. Therefore, these wireless earbuds are not recommended to purchase.

If you need a practical headphone that works for you instead of the JBL Tune Flex wireless earbuds, you can spend about $100 to invest in a better performing headphone, like the Wissonly Hi Runner bone conduction headphones.

Recommended reasons are as follows:

I noticed Wissonly bone conduction headphones when they were first crowdfunded online. And later, I saw that some otologists were recommending them on online forums, so I bought them. This Hi Runner is their flagship product whose overall functionality is also the most perfect.

The headphone use the latest research from the Wissonly lab. It increases the vibrating area of the vibrator by 35% and optimizes the direction of sound transmission to make the sound more concentrated, resulting in a wider range and more spatial of the music.

The brand claims that its sound quality is Hi-Fi level, and I actually tested it myself. I thought that the sound quality was very close to Hi-Fi level, but it did not reach this level. Of course, the current sound quality is satisfactory enough.

Wissonly Hi Runner bone conduction headphones are also equipped with a new Bluetooth 5.0 chip that has stronger anti-interference ability, that can easily cope with various complex outdoor scenes, and ensures the good mood during exercise is not disturbed by disconnection.

Meanwhile, the stable connection also brings low latency performance, and there is no problem in listening to songs, following dramas, and playing games.

In terms of comfort, the Wissonly Hi Runner performs well, it is very light, only less than 30g, and it does not feel any weight to wear. The body is made of titanium alloy which makes it have a good fit, and you don’t need to worry about their falling off during sports.

What’s more, they have 32G of built-in memory that can store 5,000 songs. This helps you to enjoy music when you are exercising outdoors without your smartphone. The waterproof rating of the Wissonly Hi Runner deserves special mention, and it is IPX8 grade. It means that you can carry it underwater for up to 20 meters and still use it normally, which is crazy!
