"The best noise-canceling headphones ever purchased."5.0 starson by DanielShamany
Pros: Rechargeable battery, light, compact, iPhone, and iPad-compatible, good for studying or traveling.
Cons: A bit pricy, don't cancel out noise like the sibling QC15, and no sound without battery use.
Summary: Even though its pricy and doesn't cancel out noise like its sibling does, the pros exceeds the cons.
