These earbuds are too big and uncomfortable for smaller/womens ears even when you twist them into your ears as instructed. They really should offer two sizes in small/medium or medium/large. As for sound quality, I can't comment as the speaker is covered by my ear since they do not fit properly. To sum it up, only buy these earbuds if you have larger ears.

Comfortable, styleish, and great sound range. Battery life was also good. My issue with these ear buds was that the fit in the rear was not super snug (like some with the rubber ear piece that his in the ear. Therefore, the noise cancelling was not good enough on an airplane and i could barely hear video i was watching.

Great earbuds, no problem charging up quick and connected quickly to iphone!

Nice sound, good bass, comfortable

[This review was collected as part of a promotion.] These buds sound AMAZING. Crystal clear audio on phone calls, which I use these for 99% of the time. Easy to set up and very comfortable in ears. These are really great ear buds, and I highly recommend these!

[This review was collected as part of a promotion.] The JBL Live Flex / Perfect Fit won't disappoint! Great sounding earbuds, with a super comfortable fit. These will definitely be my new "go to" buds. The fit is very comfortable and they stay in place quite well. Easy to pair with phone and take calls pretty seamlessly. The total charge time is off the chart, 8 hours in the buds plus another 32 hours charge in the case! I downloaded the app that comes with them, that allows you to customize the buds to your preferences. You can adjust the equalizer setting on the earbuds, but you have to exit the song, adjust, then go back to the music to see if they are set where you would like -- would be better if you could adjust while you were actually listening to the song, but still a great feature to have. I also like the fact that the case shows you with light bars how much charge is left in the case from 1 bar to 3 bars. Overall a very nice sounding comfortable bud at this price range.

[This review was collected as part of a promotion.] I have been using a lot of earphones over the last couple of years, and these JBL Live Flex are just up there dominating the heavy-weights. The fit snuggly for my large ears, and I did not feel even a bit uncomfortable wearing them of hours in stretch. The active noise cancellation is superior in quality and performs well to obstruct the surrounding sound. This helped me a lot concentrating in office work, even though I have nothing playing in them. The sound quality is crystal clear, and I have been able to answer calls during gym sessions, at cafeterias without any issues. The bass could be better though. The build quality is also good. I was worried about finger-print marks on the black body, but have not seen that issue over last 3 weeks. The battery life is beyond expectations. I never drained the batteries using the headphones throughout the work day. The Active Noise Cancellation is clearly superior to the first generation and the addition of Adaptive audio is super cool and very useful. The headphones change super fast, and I do not have to worry about them losing charge. Hope you find this helpful, if you have any questions please comment them!

[This review was collected as part of a promotion.] JBL is a class act. From the packaging and the overall feel and look of the product is fantastic without shouting, "Dig me" The JBL app just keeps getting better and better. The set up is very easy and the hearing test to configure the Live Flex to your ears was absolutely brilliant. In my experience the test had consistent results after 3 and more attempts. Bluetooth connection was immediate with a strong signal that did not drop out even with moving away from the source. However, I could not get a comfortable tight fit, (No rubber inserts), which negated the sound and had direct impact on the ANC with outside noise leakage. With all the positives, the lack of a proper fit degrades the sound quality and renders the ANC useless

[This review was collected as part of a promotion.] Never been a fan of earphones because they tend to fall out but let me tell you how comfortable these sit in your ears. They go for hours on a single charge and the noise canceling really works. The base on these things are extraordinary
