[EX Q]: Do not replace your Bose headphones. Get these replacement pieces, throw the stock ones away. These will make your headphones sound the way you hoped they’d sound when you got them. I went for a 20 mile bike ride with them stock and when I got home I checked the mail. My replacement (nibs?) were delivered. I put the new ones on and threw out the old ones. The sound is incredible. Get them. Even if you aren’t sick of the stock nibs. Get these. You won’t be sorry.
[EX A]: positive

[EX Q]: I ordered these for my beach wedding. It is supposed to come with a PAIR, meaning two, one for each foot. When it arrived it had only one of the two in the package. I tried contacting the seller 2 weeks ago and still have not gotten a response.
[EX A]: negative

[EX Q]: Item was not delivered and returned to sender, still waiting on details and whether I'll get a refund! Should have read the review first before ordering!
