I got the Earfun Pro 4's but the listening time is really not what it's promised to be...At all...

After a few months of being part of this sub it seemed to me the airfun pro 4's were getting the most positive feedback of all the pods (in their price range) overall, so it seemed like a no brainer for the price and just the overall feedback.

Another main reason if not the main reason I got them is because they say in the product description "Experience up to 11 hours of battery life on a single charge" and I really needed buds that had a longggg playing/battery life from 100% charged.

I got em - Charged em to 100% - Set em up as directed - And overall they were decent but then they (power/battery) died after 6-7 hours tops.

I did set it to "Strong ANC" / noise cancelling which is the only thing I heard takes a bit extra battery energy - But 6 hours?

I know allllllot of you guys have these so is this me doing something wrong or does it sound like they are defective ?

Please advise and thnx in advance.
