A:AnswerThese are Class 1 Bluetooth 5, which is the current state of the art--I think the rated distance is 33 feet.
Anyway, I use these with my Apple Watch, which is on my left wrist, and only get a very brief dropout once in a blue moon. Other, earlier technology BT buds that I have owned would drop out regularly and near the end of battery life. These easily handle a two hour session at the gym and they pair almost instantly.
A:AnswerActually the charge time is the biggest flaw with these ear buds. I only get 2-1/2 to 3 hours per charge with these. That is pretty poor compared to others on the market.
A:AnswerThey should be lit when charging is either occurring on the case or when you replace the earbuds. Try a different ac adapter, otherwise I would exchange the item. This is a great set, mine have been perfect since I bought them 8 months ago.
A:Answeri had those ear buds for one week and they stop working . It was frustrating getting them to work , they never did . Today , i try again and i only can hear music on my left ear and nothing on my right . i did all the jlab instructions both written and video and still nothing . I paid $50 for them and it was a waste of money.
A:AnswerFor my sorprise people at the other side of the line hear me way better then others expensive wireles headphones (beats over the head ) so YES they work perfect in making or receiving calls , I do have a little problem the size of the earbuds is little to big ,might be to keepem in place ,feels little uncomfortable at first,keep that in mind
