I was extremely skeptical, bc if you're anything like me, you're tryin 2 find a good deal, w/out havin 2 pay these OUTRAGEOUS prices for Sony, Beats by Dre, JBL, Bose @ like $200 or MORE for some, even on sale...but these will utterly shock u, they did me for SURE. If you're reading this, I'm guessing you're doin same thing I Was, basically lookin for ANY bad review, bc usually the only folks who comment on products are the UNhappy ones, but I had to scroll through literally like, 40 or 50, & STILL couldn't really find a SINGLE bad review, overwhelmingly positive. They charge quickly, u get USB-C charging, so it's fast, not sure If they do that "quick charge" thing the high-end ones do, where u can charge for like 5-10 minutes & get like 8 MORE hours, even from a partial charge, but even if not, these are STILL, WELL worth it. The one downside, is minor, the "transparency" mode, does kinda sound like you're underwater. If you're not familiar w/the newer tech, it let's u press a button, switches from 1) regular sound 2) Noise-cancelling mode 3) "Transparency" mode, which allows you to hear what's goin on around u, w/out havin to take the unit ? itself, off your head. I totally get what people meant by it sounding like you're underwater, but it still works relatively well...plus it's not really the type mode you're gonna spend much time in, kinda more for minor emergencies, or just an additional convenience to hear another person for example, w/out havin 2 physically take em off your ? ears. I'm sure like nearly all products, if you're not happy, u can return, but I can't imagine why u would. Oh, 1 thing, be CAREFUL about the color, for some reason, they had a few colors like Blue, I think like red or pink, & one other, they were 10$ cheaper I believe, but the black ones I think look better, & had a sale which saved quite a bit, I think it was like 50% off or somethin, PLUS ➕️ an ADDITIONAL 10% off coupon, not sure if that would be eligible for everyone, but was for me, which made it even MORE of a no-brainer ? to buy. The sound, even in "normal" mode, is SURPRISINGLY good, even it blocks ? out a decent amount of sound on its own, but when you hit into the Noise-cancelling mode, they sound EVERY bit as good, as my much older Bose ones, from back in the day. They were like maybe, 7 or 8 years old I guess, give or take, if anything these might be BETTER. I'm sure there's a few things the Sony/Bose ones do better, but here you're paying LITERALLY like 10% of that. I thought for SURE it sounded "too good to be true", but so far, I now understand why the reviews were so overwhelmingly positive, I had a hard time finding even ONE bad one. They fit well, pretty comfortable, my major in college basically required ?, & these sound just as good as the numerous Sony models we used. Of course the highest level ones, that cost like $250 or MORE, will probably sound a LITTLE better, but I've used probably a dozen or so different brands & models over the years, & if u did a "blind sound test", I'd say easily 9/10 people wouldn't be able to even tell ANY substantial difference. JBL has a pair for like 100$, I think that was even the sale price, but had MANY reviews that were horrific, & people even had several photos or videos showing how cheap they looked, & broke w/a QUICKNESS, I was honestly surprised ? the MORE expensive ones, had VASTLY worse overall reviews. I can't speak on Longevity yet, but they charge quickly, sound VERY good, feel comfortable enough to use for long time, & of course, the price is UNBELIEVABLY good. Others @ this price, have MANY bad reviews from unhappy customers, but here I struggled to find ANY. I don't even usually do many reviews, unless I'm VERY happy/surprised, or very unhappy w/a product, these are DEFINITELY worth taking a chance on. I recommend waiting on a sale, & keep an ? eye out, for the additional coupon thing u have to hit the ✔️ ✅️ check mark button to receive, but ANY price around 30$, you're gonna be straight up SHOCKED w/these, I was. That's about all I can think of, bass is solid, price is fantastic, comfortable, not very heavy or anything, even WITHOUT the Noise-cancelling, the sound is great & even STILL blocks a decent amount of sound, WITHOUT even activating the Noise-cancelling mode. I wasnt familiar w/the developers who made these, but so far, @ least short-term, I Would give em literally like a 9 to 9.5 out of 10. Even the higher end ones, like beats by Dre, have more bad reviews than these...possibly bc more people bought em overall? Not sure, but you'll not find a better set of headphones ? anywhere CLOSE to these, for this price. Very impressive. If anything, I'm usually MORE skeptical than most people, but I don't see how anyone could be disappointed w/these, especially for the price. Two thumbs ? up
