question:
Don't waste your money on these. Sound quality is good for the price, but the headband broke within a month. I am extremely careful with my electronics, and barely even used these things... maybe a dozen or so times before the headband broke. Too bad, I thought I finally found a quality pair of BT headphones at a decent price.
answer:
negative


question:
I got this as part of a joke costume for a trip. Ironically I had numerous compliments on it from people who thought it was real. To be honest it is a pretty good fake from a passing glance. The best fake chain I've seen. I need to order more as my nephew broke it when playing with it.
answer:

positive
