The Jack started to become defective and within a month, no more sound.  Luckily, Amazon allowed me to return them.  I had them 32 days, and the cutoff was 30 days. 
 
I am torn with purchasing another one or searching for something else.
 
The sound quality was amazing.  I only needed them for home so they were not intended to be used at the gym or during commuting.
 
I did routinely connect it to my tablet for phone.  The weight of the cord wanted to drag my device around.  I had to secure the cord to ensure my phone or tablet did not get pulled to the floor from the table.
 
Keep these factor in mind.
