The only downside I've noticed from these so far is that its slightly odd that to turn the volume up, you hold down the left earbud, and to turn in down you hold the right one, same for skipping songs forward you hold the left, and backwards you hold the right, seems sort of backwards, but I could get used to it

The left earbud died on me after 3 1/2weeks!

The left earbud would not work

Today, the left earbud wouldnt work or charge
