I bought these headphones and took care of them the way you are supposed to. About a month after I purchased them, The telescoping arms broke. See attached pictures. I had to glue the pieces together to use them.

I bought this JBL LIVE 650BTNC 5 months ago and still working on it perfectly. It has an amazing sound. It is worth the price. Good built quality. Also, its Bass is very cool. It can use up to 30 hours without active noise cancellation. And only we have to charge it for two hours. Also, it supports quick charging. And it has a good active noise cancellation system. My headphones are too useful because also they are built-in Alexa.

I have been using this product for just over a month, the sleek design is very comfortable and the features on it are good with the alexa app. However it is difficult at times to work with the alexa and JBL app, when pressing the button on the side of the headphones it can be temperamental, by this point it is easier to have just used your phone in the normal way. I have used these in the gym and they are great, however I have also used them when running and they give a wind noise through them which then distorts the sound. The volume of these is not able to counteract this as it is quite low. All in all, great for times where you are still and sat down, but not for activity.
