High volume level seems like medium level and medium is low.

Thank you for bringing this to our attention. To get the best possible sound from our JBL Endurance Race TWS, the most important step is achieving a secure, airtight seal by angling the earbud downward and gently twisting it into place. We recommend experimenting with all the provided ear tip sizes to find your perfect fit, as a proper seal instantly improves bass and clarity. If you’ve found that perfect fit but still notice a volume difference, the issue is typically caused by minor debris on the ear tip screen, a balance setting that needs to be centered in your app's accessibility menu, or a temporary glitch with your source device. Taking a moment to clean the tips or test them with another device usually resolves this quickly and gets your audio back to a balanced, high-quality level. If the steps didn't work, please contact our customer support for further assistance.
I thought this would be noise cancelling but it is not. I have loud mouthed guys that come in at night and I need to drawn them out. I still can hear every word spoken.

Thank you for your feedback. Our JBL Endurance Race TWS does not have a noise cancelling feature. It is designed with Ambient Aware where you can enjoy listening to music while increasing ambient sounds, and TalkThru, it lowers music and speech is amplified. If you're interested, you may check out our JBL Tune series earbuds which has noise cancellation features.
A month after getting these, and being EXTREMELY CAREFUL to not get them wet or drop them (yes I know they’re sport buds so technically you can), the right earbud completely stopped charging or connecting to the case/phone. Waste of money and I don’t have a lot of that right now

I bought these earbuds about a year ago, this was my second time buying them as the first were not as sweat resistant as advertised-thought I just got a faulty pair. But I didn't feel the need to leave a review then, now I do. These current earbuds were not playing music out of nowhere. I reconnected them/troubleshooted, but they BLASTED A HIGH PITCH NOISE IN MY EAR! Nearly damaged my eardrum! It started playing the noise it plays when you lose an earbud when i was just pressing play on Spotify. These are so dangerous! Highly recommend spending more for the other more reliable brands like Beats or Apple - your eardrums will thank you!
I have it for a year. But lately started exercising more often, and it's getting warmer as well.
So, this is NOT waterproof earbuds as it claims to be ! It can't handle some sweat and earwax when you're running and sweating.
Right one is lower volume. I tried nipping it into water and soap, worked for some time, until i got sweaty again, and I guess not so much sweatproof.
It may be "waterproof" in way most buds are, if you splash it on whole casing, but its not waterproof in keeping same sound or even volume quality if you simply get sweaty from exercise and sweat doesnt evaporate as quickly
(i even tried immediatelly drying it off, after running, also cleaning my ears (i guess i looked weird cleaning ears like that in public, but to take off any sweat, but still made no difference)
