I posted here last year after I bought the 700’s when they first came out. I was having repetitive issues with crackling noises, and it was really a bummer. Like most of you here, I posted my frustration, tried to troubleshoot, and was left feeling like I made a bad investment. However, 2-3 months after, the cracking noise never came back. Its been a long time now (technically, since avengers end game came out on iTunes, lol) and still no cracking sound. I use my headphones every day for work now, and have no gripes. I hope this gives readers some faith that it might get better! Also, fyi, I’ve not been compensated by Bose or anyone in any way.
