I've spent a lot of time perusing online discussion threads, reviews, and videos. For a long time, I had serious worries because of all the negative recommendations, but after making the purchase, I am completely confident. I've never been a fan of this style of headphones because the quality is often terrible (hello, airpods, you have the worst sound in the history of ever). These 12k closed-type headphones have a sonic quality that blew my mind. Everything from the lows to the highs is spot on. Discovered to my delight. Second, it doesn't require any case opening or hand holding to utilize. I inserted it into my ears, and it immediately began functioning. Third, they claim there is no noise reduction despite the many positive reviews (guys, study up on how to properly place their rule; updated guidelines can be found on the web). These headphones' active noise cancellation is among the best I've used. The subway system is reliable. Although these ears may be lauded at length, I must warn anyone with small ears that these headphones are not a good fit.
