Design and Built Quality

JBL Tune 230NC TWS

As a matter of Design, JBL Tune 230NC truly wireless headphone built with only 10gram weight and also come with three sizes of silicone tips to choose from. My ears are a bit small so I find these headphones a little loose but if your ears are big then the size range will likely suit you very well.

The charging case of JBL Tune 230NC protects earbuds very securely. However, if you want to charge earbuds, you will need a charging case. – So don’t lose it. If you drop it, the lid will open and send the buds flying in random directions, too. Additionally, unlike the HyperX Cloud Buds, it come with an IPX4 ratings for water and sweat resistant. Which means the earpieces can withstand light splashes from any direction, so exposure to rain and sweat shouldn’t be a problem. The IPX4 rating doesn’t extend to the charging case, so you must fully dry the earpieces before docking them for charging

The charging case is a bit stuffy and hundram. But its exterior is a bit black and slippery. Its flip-top lid shows the charging docks. The front has a status LED, while the USB-C port (via USB-C-to-USB-A cable) sits behind for charging. Helpfully, the buds only fit properly in one orientation in the case.

Audio Quality

JBL Tune 230NC TWS

Coming to the audio quality, the Tune 230NC provides fairy better audio quality with good amount of bass with the 10mm Bass Boost Driver. JBL’s devices are world famous for its frequency response. Talking about the bass, the JBL Tune 230NC’s bass is very good and also pays close attention to its mids. However, it’s not a problem here. Presumably it’s a reference to the brand’s reputation for bass-heavy sound and inclusive ANC. Put the hype aside, if you remember that this is not a studio monitor. But rather travel and exercise earphones-you’ll enjoy what you hear.

Furthermore, with Active Noise Cancelling and smart ambient, you can hear more of what you want, less of what you don’t. ANC with two mics lets you minimize audio distractions. With ambient aware, you can tune into your surrounding at any time so that you feel safer when you’re out in the world, while TalkThru lets you stop for a quick chat without having to remove your headphone

Connectivity, Pairing and AI assistant

Moving to connectivity option, The JBL Tune 230NC TWS offer a Bluetooth 5.2. Thus, you connect with Android, iOS devices along with MP3 players with Bluetooth support. Additionally, it support SBC and AAC Bluetooth codecs. So, if you have Apple smartphone, you can take advantage of AAC, but Android users don’t get aptX or any other high-quality options. In an attempt to make up for this, the JBL Headphones app offers three playback modes: Normal, Audio, and Video. The last mode is meant to combat audio-visual lag, and while it is better than Audio mode, it’s hardly perfect.

Moreover, If you remove it from the charging case, it automatically enters the pairing mode. But, it did not support the Bluetooth multipoint. To put the earbuds into pairing mode once more, you must put them back in the case and take them out or tap and then tap-and-hold a bud until they re-enter syncing. Make sure the last device’s Bluetooth signal is off before doing so, otherwise they may connect to it again instead.

Battery Life

JBL claims that the Tune 230NC TWS earbuds can last up to 10 hours without sound cancellation plus another 30 hours from the charging case. Enabling noise cancellation reduces it to 8 hours for buds and 24 hours for case. These earbuds produce a tone once they have run out of 50% of the battery and run again after every 10% until they run out, which can be annoying. The application also does not have a clear way to disable this feature. You will need a case to charge the buds. They come with a short USB-A to USB-C cable, but not a power adapter. Note that the hole in the charging case is cut very close to the shape of the included cable, so the third-party cable may not fit.

Our standard headphone battery test uses continuous playing music with a maximum output level of 75dB (SPL) measured on the ear drum of our test head. Lasted 8 hours and 25 minutes with JBL Tune 230NC TWS ANC enabled. This means that JBL’s battery life estimate is very accurate and you can get it by listening to songs at work, but later you will need a charging case before facing the gym.


This earphone offer a very good active noise cancellation and audio performance for under $100. And because they’re sweat- and splashproof, using them during workouts won’t be a cause for concern, either. But as good as all this sounds, the JBL Tune 230NC TWS is not very comfortable. Also, its odd use is like a chirp with the battery sinking below 50% and the unstable charging case makes it completely less attractive.

What is the difference between 7mm and 10mm drivers in Bluetooth earbuds?

The size of the best driver depends on the specific headphone design. Earphone drivers are usually 8mm – 15mm in diameter while headphone drivers are usually 20mm – 50mm. Larger drivers produce stronger sound waves (especially in bass / sub-bass) but that doesn’t mean they sound better.

That’s why the 10mm driver produces stronger sound waves which means it will produce louder and better sound than the 7mm drivers.

Hopefully I have dispelled all your doubts but still if you have any doubts, or if you want more detailed explanation than feel free to ask, I will reply you in next 24 hours.

Do wireless Bluetooth headphones cause cancer?

Yes, the radiation emitted from your cell phone is transmitted through both wired and wireless headphones. It is believed that less is transmitted by wired than by phone but also less by wireless. It doesn’t matter if your immune system is slightly lower than yours, you run the risk of developing a rare tumor. In addition to the annual outbreak of the flu or cold, depression also lowers your immune system.

That thick instructional book about your phone contains 5 point font btw radiation information in the back. This is legally considered the full ad!

Think logically. What protects your brain from radiation coming from your eardrums? There is no muscle or fat in the straight canal of your brain.

When I was in high school I would fall asleep talking to my friends on my cell phone at least once a week. Since I am left handed always my left side. And it was in my left ear that I had my acoustic neuroma.

I know more people who had it or had it. All the other patients I was in the hospital with, along with family of friends and relatives who had my specific tumor, lived only a few months to a year after surgery. I am literally the only survivor out of 19. We were all between 23 and 35 at the time.

Prevention is always better than trying to cure the problem you are having. Buy an old school boom box, turn down the volume and go to bed with it.

I also want to tell you that recovering from brain surgery is awful. I was really mentally disabled for a moment, could not communicate my thoughts, could not walk because half of my body was paralyzed from head to toe including half of my face, could not eat food for a while, looking through one eye for a while I couldn’t, I couldn’t take a shower, I had to take big pills for my heartbeat, which was like hitting my head every second, I couldn’t sleep for months because I could get brain fluid leak = instant death and more. Is. Therapy was a bitch that involved electric shock. My eyelids were covered on my face because those muscles were also paralyzed. All this on cell phones.

What’s the difference between “wireless” and “true wireless” headphones?

“True wireless” connect the 2 ear buds wirelessly to each other. It means all this radiation is going through your brain for 3 hours continuously if you are using your lovely airpods for 3 hours.

I know, it is said Bluetooth 5.0 is very low energy. Still, I wouldn’t like any radiation going from my right ear to my left ear(through my brain), for such a long time.

Use true wireless ear buds with moderation, then.

“True wireless plus”, on the other hand, connect each earbud directly to your smartphone. It sems safer, however, still, there is 2 signals going to your brain(left and right ear), from your media device.

“Wireless” headphones, seems to be much safer, as each ear buds connect to each other via a cable(neckband).

Radiation is tricky and there are “researches” about the harmfulness or not about it, so take yourself your precautions.
