What I assume the other users complains are true about connectivity issues but some one suppose to guide them;
1)Connectivity issue is not the Anker or Zolo issue. Basicily its customers awareness issue. As every one knows all BT devices work on RF in case of music its one way but when you call (interact with device) its two way process. I personally tried some phone safety/protective cases and the result was negative, I barely listen the music or call. Reason.... All bt devices are designed to meet the standard mobiles without calculating the blockage caused by armour or other protective cases. So yes My Zolo Liberty works fine till I use the phone without any extra layer of protective case. But soon I mount a protective case the RF signals disturb due to extra layer.
2)The charging issue..
As per battery university a continuous caharge may decrease the battery life. Every one knows that all thypes of batteries having different but limited charge cycle (350 to 600) then they become weeker and weeker.
Ithease of Liberty or Plus Lets suppose the battery has a charge cycle of 600 so if I put them 3 times in the case its 90 cycles a month now you can calculate the battery life.
3)User say that the sound in not coming or slow from any of the earbud. If you consult with the hearing aid users you will come to know that they use to clean the earbud every week to keep them working.
So the users need to clean the earbuds to avoid choking.
And yes there might be some real faults but not in all units.
Mu humble adv to all friends complaining about the product; Plz check at your end first. Are you taking good care of your unit (its not Anker or Zolo unit any more because you paid for it and you have to take care) If yes and you are facing any prob Anker is always there for a aftersales service.
