I also appreciated the cord which came with it in case you wanted to listen to music plugged in on the off chance your battery was weak or not topped off enough

Working an 8+ hour day wearing these does not stress the battery at all

So in short, great battery life, great audio, great bass but the highs were just not there for me.

so you're not depleting the battery

It sounds as good as or better than headphones costing three times as much
