Great product. My only concern is the left ear piece. The right ear piece is clear and has great sound quality. Unfortunately the left ear piece is full of static. I would rate this a 5/5 but the left ear piece shot it down 2 stars.
No instructions ame with the buds. Need instructions on how to use them???

Thank you for your question. You can search for the JBL Tune Flex on our website. Below the documents section, you will find and be able to download the quick start guide.
Sound is great, but they don't always disconnect when put in case. When they were new they didn't like to charger either. Also I use only one earbud at work and the functions when using only one side are limited, would be nice if in single mode the left and/or right had the same functionality.

I accidentally put these headphones though the washer and dryer… I thought they were done for… I took them ear buds out of the case and let them sit for over 12 hours so they dry out and they are working normally now!
I like the look of these headphones, and the battery life is great. However, I have small ears and these earbuds are too big for me, so the fit is very loose and they are prone to falling out. Also something is really wacky with the sound levels. I've had them for less than 3 months and the right ear bud is significantly quieter than the left. There is nothing blocking the speaker, I've checked. If i turn up the volume it seems to switch sides, like lower volume it predominantly comes out the left side, and if I turn it up more the right side will be louder?? I don't really know what's up, but it is annoyine especially because I am on noisy public transit a lot of the time. If I'd known I'd have these issues I would not have purchased,

Thanks for bringing this to our attention. We recommend cleaning the contact pins on the case and earbuds using a cotton swab with alcohol. Charging issues are frequently caused by foreign matter on the metal charging contacts. This can include sweat, grease, ear wax, etc. Please ensure the pins are dried before placing them back on the case. If cleaning doesn't solve the problem, the next thing to check is the balance control by checking the balance control on your source device by going to the "Accessibility" settings, on your music player app, commonly found in the playback or EQ settings, and the balance control on the JBL Headphone App. Lastly, try to connect the headphones to a different device (phone/tablet/music player) to see if it fixes the problem. If the troubleshooting steps do not work, we'd like to work with you directly to address the issues you're experiencing with your JBL Tune Flex TWS. Please contact our customer support.
