Edit: I ended up returning them due to the pressure feeling of the anc and lackluster comfort.Alright, so I have them in hand now and used them for 7 hours consistently. Here are my brief thoughts.These headphones are great imo. But I wouldn't necessarily pay more than $80 because it's good, but there are places where you can see where they definitely skimped on quality. TLDR: Good sound, ok design, good noise cancelling, excellent ambient sound mode, comfort is meh and is somewhat lacking, but not uncomfortable, controls are easy to use.SOUND: Alright, so first the sound. These sound great, they include punchy bass and clear highs. Vocals are nice and bright. Bass is emphasized and detailed, also there is nice sub-bass. Treble is slightly silenced and sounds smushed or weird in my opinion. A simple eq can fix that though. Overall good sounding, could be better, but not complaining.NOISE CANCELLING: The active noise cancelling is not bad on these headphones. The do block out a significant amount of background noises. There is 3 levels to the ANC. With 3 being the strongest, it cancels lots of outside noise, but there is also lots of white noise. There is a pressure feeling with level 3 and you feel like you should pop your ears, but it's only really noticeable while not listening to anything; with music it's fine. Level 2 is the best mode in my opinion because there is the least white noise and it cancels out a decent amount of noise. Level 1 has the least amount of noise cancellation, and somehow has more white noise than level 2. This mode is good for when you want to block out background noises, but still want to hear outside noises like on a street. Overall decent noise cancellation.DESIGN: The design of these headphones is aesthetically pleasing. They look great with a simple minimalistic approach. They are made mostly of leather and plastic. There is no metal on the build of these headphones at all. This surprised me as theses retailed for $250. The extension arm and the hinge are both made of plastic. The extension arm is alright with clicks that are ok, but sometimes I over extend it or close it all the way accidentally. I feel that it would be much more premium with metal extension arms. The hinge is also made of plastic, but feels solid with a nice firm open and close. The outside of the ear-cups are made out of plastic also, and the edges of it are a different cheap plastic. The part of the headphones that you would hold to put them on and take them off slightly sharp and doesn't feel premium.Comfort: The comfort and wearing feel is where this pair headphones lacks the most. This pair of headphones looks really great and super premium in the pictures, but I feel like they forgot to consider the wearing comfort of these. That being said, they still are decently comfortable. The whole headband is leather which is nice, but the padding on it seems pretty thin. Occasionally I feel most of the weight on the crown of my head. The ear-pads are nice and soft and my ears got warm after wearing them for 4+ hours, but no sweat or any real discomfort from the leather pads. The padding beneath the ear-pads should have thicker padding because my ear touches the plastic driver cover every so often. This gets annoying because the plastic cover sticks out too much in my opinion. After slightly adjusting the headphones, me ears don't touch the driver cover. The ear-pads are a bit small in the inside, and I wish that they were more roomy inside so that I wouldn't have to adjust them up and down a little with the 3d ear-cup thing every so often when putting them on. And btw, don't even think about having them lay flat on your neck, there is lot's of clamping force that it practically chokes you. You can have them around your neck normally, but I find that uncomfortable also. The clamping force on these headphones is quite strong, and you can't really loosen it because the headband isn't made of metal. I'm hoping that it will lessen overtime. Though there is lots of clamping force, the ear-pads nicely distribute the weight around the sides of your head. This makes it easy and not bothersome to wear glasses because the pressure is distributed and not in the middle. The leather is soft which lets you slide your glasses on and off without struggle.AMBIENT SOUND MODE: Strongest point of these headphones, really. To activate the ambient sound mode, you simply place your right hand on the right ear-cup, and it will lower the sound of your music and play what the microphones are hearing on the outsides. When you remove your hand from the ear-cup, your music will go back to the original volume and your noise cancelling will resume. This makes it so you can hear your surroundings well and make a quick conversation. To toggle this mode you have to hold your hand on the right ear-cup and hold the noise cancellation button for 5 seconds.Controls: The buttons to control the noise cancellation, music, etc..., are all very simple to use. No complaints here, there is a rocker for volume which doubles as a play pause button and skip/previous track button. Noise cancellation can be toggled on and off with holding the noise cancellation button for 2 seconds. Press once to toggle between different noise cancellation modes. Power button works as intended, but it's hard to distinguish which is the power and which is the noise cancellation button because both have the same little bump and there is no gap between the buttons.Accessories: This set of headphones comes with a nice leather carrying case, a 3.5mm cable to use them wired for the high res audio, a micro usb cable to charge them, and the usual manual/papers. The carrying case is nice with small organization pockets inside and is hardshell; zipper is nice and smooth. I just wish they didn't use leather on the outside because it will get scratched up since it is a case. The high res audio is said to work only wired online, but the box says high res wireless. I have no real way to test this as I don't have any high res audio compatible devices. The micro usb cable supports quick charge and gives these cans 2 hours of listening with only 15 minutes to charge.Conclusion: Great pair of headphones that are worth picking up, but I wouldn't purchase them over $80. Checks all the boxes for a pair of headphones I was looking for. Decently comfortable, great sound quality, build is ok, accessories are nice, everything works as intended, no real gimmicks.
