Summary: Bought one pair for myself for travel, and now I'm buying another pair for my husband. I was amazed about how good they sounded in a crowded waiting room amidst public address announcements and crying babies.
Pros: efficient, great sound, played some halestorm, sounded better than my klipsh ear buds. yeh yeh they are not comfy, look cheap, but for 11 bucks outstanding. probably would pay the 30 dollars just for the sound.
