The JBL Tune Flex are decent for commuting and travelling. They're very light, portable, and have a comfortable fit for most people. They last for around 6.5 hours of continuous use with ANC on and come with a case with four extra charges, so you can always pop them in for a quick recharge during...

I’ve written recently, this model seems to stand out most, especially given the budget-friendly price. What can you expect in terms of sound and design from the

The JBL Tune Flex are some of the most versatile true wireless earbuds you can buy because they can be used as open-ear headphones or as in-ear headphones thanks to the included set of silicone tips. Granted the former won't give you top-quality sound but it's great to have the option.

I have had the JBL Flex for 4 weeks and now I would like to share my experience. When I was looking for new headphones, I came across the JBL Flex. When they arrived I was pleasantly surprised. they are very light and have a great velvety smooth surface.
Battery life is excellent. I can get 8 hours charge and you can use one bud at a time if needed. Sound quality is 5/10 materials is probably a 3/10 Battery is 9/10. I have some trouble actually gripping the buds when taking them out of the case and its a very low friction slippery plastic case.
These can be aggravating to connect as the frequently need to be put in and out of the case to start. Once connected, the sound is okay but the noise cancelling is barely noticeable.
The sound quality is good but what I didn't like is the gesture confirmation/layout, whoever designed hate the brand, you are not able to change volume, change music or select noice cancelling, you are only able to use 2 of those optios on the headphones, but the voice assistant option is available...
The different attachments allow the headphones to fit the ear wonderfully. Slipping out is therefore almost impossible. I find the sound excellent and the anti-noise cancelling works wonderfully. The app is also super easy to use. Unfortunately, I did not find the range particularly good.
Exactly what i needed. Doesn't fall out of my ears. Sounds good and the microphone is clear on the other end
Good bass response. Noise canceling picks up plenty wind noise when used outside. Best to turn it off if you’re planning to use it outside. Buttons little too sensitive as I keep toggling the noise canceling & play/pause when adjusting position in my ear - but I guess that’s better than having it...
Disappointed with these. They don’t fit in your ears and will fall out. Sound quality and noise cancelling is pretty good if you can manage to fit them properly in your ears. I’ve tried all the different sized rubber bits they give you but I think it’s an issue with the shape and size of the actual...
Really did not like these. My ears were aching in the first five minutes and the ambient noise feature did not work at all. They are stylish and I like the overall look but for my ears, they’re not comfortable.
JBL did the thing with these headphones. Easy to connect to my iPhone. Came with helpful setup information. The app for these headphones provide the ultimate experience. I work in a loud environment at times and the app allows me to control how the headphones react to the noise around me.
