I bought these for $88. For that price, they're pretty good. Maybe a pair of sennheiser or some other brand would have been better. I don't know; I'm not going to go looking for reasons to regret a purchase that I'm largely satisfied with.Pros:Battery Life: Battery life is excellent. I didn't keep track of the exact number of hours I used them, but I used them most days my 3-week winter break without having to charge them until I got back to school.Sound quality: They sound different than my other headphones. Not necessarily better or worse, just different. I like themBluetooth Connectivity and Physical Buttons: Connection is stable with a really good range. I can wear them on almost the other side of my house from my phone/laptop. That said, I've had a couple skips just walking down the street with my phone in my pocket. Weird, but it's barely noticeable. Physical buttons for play/pause/skip and volume are nice, as well as a headphone jack.My favorite part of these headphones is being able to just turn them on and start listening almost immediately. Not having to deal with wires is SO much better than I thought. (I still like to wear more comfortable headphones if I'm gaming/sitting at a desk, but if I'm walking to class, these are just SO convenient)Cons:Comfort: The original earpads that came with these were pretty bad. They are small and my ears touch the plastic frame inside. You don't notice it at first, but I could only wear the headphones for about 40mins-1hour before my ears started to hurt. That said, I have pretty large ears and a pretty large head. You may have noticed from the pictures that I put a different pair of pads on them (Audio Technica ATH-m40x). Now they are nice and comfortable. The headband can be a bit uncomfortable after ~1hour but it's not bad.Sort of related to Comfort: I can't wear these to work out because the pads get sweaty and gross.Noise Cancelling: If you're buying these *soley* because they're ANC, don't waste your money. The noise cancelling doesn't do much at all. I can only notice a difference if I turn NC off and back on again. Worst of all, if your outside and it's even *slightly* windy, the ANC will amplify the wind and make it roar unbearably loudly like you stuck your head out a car window. Apparently the more expensive sony headphones have Ambient Sound and Wind Noise Reduction, but these have no such feature, and I always turn ANC off. My biggest annoyance with these is that I can't set ANC to be off by default.No Case: I don't really care about this, since it fits in my backpack just fine, and I'm not worried about it getting damaged. They seem pretty sturdy, and since they're not as expensive it's not a big deal.Overall: You should only buy these if they're under $100. Full stop. You should NEVER buy these at full price ($190). The higher-end sony headphones are only ~$50-60 more than these and (presumably) are better than these in every way. If you do find them on sale, maybe check out some other wireless headphones in that price range. All that said, for the $88 I paid for them, these are pretty great with the new pads. They're convenient, sound good, and are *reasonably* comfortable.
