The battery life isn't as good/long as suggested. Calls are not totally clear on either end BUT they get me through my work day listening to music so I like them.
I love the battery; compact and well built; I use them every day with no problem; I have bought four pairs, 2 for my girls, one I keep at home to connect with my smart TV, and another one for work; you can't beat the price.
I just received my new wireless earbuds and cannot get enough. They are small, comfortable, and sound amazing!!! The bonus is that they do not lose charge after 4 hours and can be used independently. LOVE THEM! I had purchased some JBL earbuds previously and was quickly disappointed on their quick ability to lose charge. I also love that the charger is built in. No need to carry extra wires. This is my 2nd time purchasing Jlab and I'm hooked with the quality, crisp sound and phenomenal bass these products produce.
I bought these because the Lenovos that I previously bought kept dropping the signal when my phone was in its belt-mounted carrier... but these do exactly the same thing. I listen to audiobooks when I take my daily walk and these true wireless earbuds just cannot perform up to snuff. If I simply turn my head to the left they lose the signal from my phone, which is only a couple of feet away mounted on my belt. Very disappointing.
If I put my phone in my breast pocket all is well. If I hold my phone in my hand all is well. If my phone is in my belt carrier I get more-or-less constant dropouts, perhaps 8 or 10 per hour, and that is not fine. My $12 drugstore Bluetooth earbuds with a connecting wire between them have never had a dropout issue... not even once.
