this charger doesn't work

I always wipe them down after a hard run and only charge them on a basic 1A charger or my laptop as I have reader larger chargers (say, my phone's 2A fast charger

I am not sure as to why the charger that they sent works more efficiently than other universal chargers, so that is the only negative, I did find one other universal charger that would work

Also, I lost the charger that came with the headphones, which seems to charge the most efficiently, and they sent me a replacement quickly and without cost

/c every once in a while there is like a scratchy sound and I have to disconnect and reconnect

Good as always,..
