I bought a couple of weeks ago and the earbuds are not what I would have expected. Unfortunately they are extremely hard to get charged as well as the battery life is only 3 hrs. The sound quality is great but ugh I'm very disappointed in the charging difficulties.

I bought these a few months ago, and wow have they delivered. I have worn them in the pouring rain, and not just a quick run into the gym. These babies withstood miles after mile in multiple rainstorms. The best thing is the sound quality has stayed consistent after each shower. Although you may have to sacrifice some sleekness and style, the headphones make up for it in durability and sound.

I normally love all JBL products. But I think I knew these were going to be bad the moment I booted them up. The left earpiece was fully dead. Looks like TA dropped the ball on this one. There is no application support to see if it has any updates. But let me get to my actual few days of actually using them: (After fully charging, went to the gym. Thought I was pretty cool with my first truly wireless headphones. Getting it connected was familiar since I have one of the speakers. But I believe a new user would not have an easy time connecting these for the first time. ) Day 1: Fast track to a workout session; they keep losing connection for some reason. Didn't think nothing of it cause it Bluetooth.. After about 30 mins of a normal paced workout, the left ear was at 20%... Wow. Strange. But okay, maybe I didn't fully connect the prongs. Day 2: Okay... I fully prepared myself to have a good workout! Connect and begin the elliptical. Move my head to the left a bit, they start disconnecting. Whoa.. Move to the right, more disconnections. Okay.. Wow. I turn Bluetooth off and on. Connection seems smooth. Bam, starts disconnecting again. Not cool. My thoughts are that there may be some interference near by(its Bluetooth) Day 3: Fully charged. Ready to have a good workout. Songs are just skipping. I have Spotify downloaded offline songs, no way its Spotify. I am trying my best to ignore the disconnections.. But when you're in the middle of a set and they keep disconnecting, it is very annoying. The worse part today was that after ~30 mins they were both at 30% battery life!!! Day 4: I test these at work today and the phone is literally in front of me, no one is using any Bluetooth devices near me. I hop on YouTube to watch this upcoming MMA fight Embedded videos. Aaand... They start disconnecting right away. I am packing these up after I finish this and returning them back to BestBuy. Not sure if I want to replace them or just go with something with a wire. I understand Bluetooth technology isn't always stable, but it is a game-changer when you can't even get a good workout in. I may have got a set of defective ones. It can happen. But the last straw was the horrendous battery life.
