Bought a pair in October of 2019 so I have used them for a while. The charge holds well before having to recharge. If they are fully charged, my iPhone can be in either pocket when I walk outside. Many times for the second use and on, the earphone I insert first determines which pocket (left or right) I have to put my iPhone in to otherwise the the sound is choppy/cuts in and out. When one of the earphones does not work when I first put them in, I have to put both back into the charger and then reinsert the earphones. The most I have had to do this at one time was three (3) times. The sound is good. At times, some people state they cannot hear me when I am making a call. I mostly use the earphones for listening to music. I like the comfort of the earpiece They are easy to clean.
Was really excited about these when buying them. Tried them for about 5 days, a couple hours each day, and my ears would hurt after 30 mins. I even tried 3 different ear tips and still got the same result. The sound quality was also not what I thought it would be for almost $400 after tax.
Sound quality is really good. The Bluetooth distance is pretty poor. The mic is really good, however; it does no block out a lot of outside noise. I would differently recommend these especially if you are doing any active that has you running,lifting, or jumping.
These headphones got sooo many problems. Charging these things is a nightmare. One day they work perfectly fine the next one of the earbud is dead... even if you double, triple check if they are correctly in place, they will be dead the next day... DO NOT BUY THIS PRODUCT.
