I got the product Jan 10, by March, it was messing up. it now will only charge the headphones if they're in the case and the case is plugged in, even though the case stays at 100. If you only have the right bud in, your mic is barely audible. it doesn't take long to charge, maybe 15 mins. however, I use them for work and twice now it's rubbed against the inside of my ear until it bled. ive had it for almost 4 months now and it still leaves my ears red and hurting to take in and out. I use them mainly at work and they barley survive a 7 hour shift- if they do survive that is, the battery isn't good anymore.
for short term use, good product. for long term use, just invest a little more money in and get an actual good pair of headphones
