I am basing this review from my experience with several pair of True Wireless In-Ear headphones. Overall, this is a high-quality product for a reasonable price, produces great sounds even if the ear buds are slightly more bulky than the competition with a charging case that is slightly larger than others too.

Overall these JBL earbuds are great at what they do and that is play music or videos, and phone calls. All in all these are a good buy if you want something reliable and easy to use. There is a lot to like and very little to dislike. The BTB on the motherboard uses OCN (Yaqi Technology) high-current connectors, model: OK-35F006-04, with a pitch of 0.4mm, a height of 0.6mm, and a current of 3A.

Using wireless headphones / earbuds is absolutely incredible and, not being tethered or having your movement restricted by cords is truly freeing. While the wireless experience is incredible overall, I don’t believe that JBL took the appropriate time to design earbuds to be comfortable, or to fit well. JBL did not make any effort to ensure these buds stay in your ears. They are bulky and insert just as any average pair of earbuds – no rubber hook, flap, etc. Just press into your ear and hope they stay in place. If you have every had difficulty keeping earbuds in your ears – these will absolutely have the same problems. I was pleasantly surprised to discover that the case supports wireless charging! Yay! Out of the box, the charging case showed two bars. Charging was complete in about 30 minutes. The controls are simple on these. You just take them off, they auto turn on, connect to your device, and you’re off! I used them with a few different devices and I never had any connectivity issues which was great. There is a small lag when trying to play/pause something with the buttons on the earbuds but it wasn’t a big deal.

On that note, there is not great way to tell what the battery level is at. The earbuds won’t tell you but the case does have an indicator but it’s for the case not the buds. JBL is an excellent company that sells fantastic products. If it’s been within a year and one side of your JBL earbuds/headphones is still not working, they will likely send you a replacement model. They will ask for your JBL earbud model number, which will be on the case. You will be asked to explain what you’ve done. They may even have additional suggestions to try. There are four primary reasons why one earbud may not be working. The first comes down to a pairing/connection issue, the second is a battery issue, and the third is a settings issue; primarily, the settings on the device you’re connecting to would need to be adjusted or reset. And the fourth is a hardware issue; this can be from damage or obstruction. If for whatever reason, the reset process hasn’t worked. You can also reset any JBL earbud via the app. Here’s how:According to 52audio, a large number of true wireless earphones from brands such as Huawei, Samsung, Xiaomi, OPPO, JBL, 1MORE, Honor, Baidu, and OnePlus have adopted BES solutions. One thing I did notice was using these earbuds to watch video content on Netflix, there appeared to be a millisecond delay from what you see and what you hear on the screen. It could be just a poor connection with the Netflix server, but there was just the slightest of lags between what you saw and the sound you heard. This is of course negligible when listening to music as there is nothing of any note to sync with. Sounds obvious, but most JBL Bluetooth headphones earbuds don’t have a huge range. You need to remain close to the transceiver for the connection to maintain. And the earbuds need to stay close together as well. After installing both the gel "sweatshield" and the smaller ear tips, I feel these are very secure in my ears. Not sure I could play basketball, but the treadmill weightlifting poses no issues. Other earbuds I've had I felt like I was always adjusting so they don't fall out. These seem good!
