Good sound quality and noise cancellation but let down by build quality
First impression is impressive packaging. Packaging has a quality look and worthy of much more expensive headphones. Unpacking the box you find the headphones, a USB-C charging cable, and a manual. Unfortunately no case for the headphones. So you’ll either have to shell out more money for the case or find an aftermarket solution.The headphones are, for the lack of a better term, chunky. The ear muffs are very large. The head band is comfortable with a very soft foam liner. The ear pads feel nice and are likewise very soft and have the very thin leather feel to them. The typical adjustability you’d expect is there and you can adjust the ear pads up and down and they pivot to fit your ears. One side is hinged so you can kind of fold them up to save a little space. This is how they’d go in a case if there was one included.On the right headphone are the controls and the USB-C charging connector. The controls have a combination volume up/down and power switch (in the center), and a function/pairing button. Press and hold the power button to turn on/off. The function button can be set to change the noise cancelling mode and audio modes based on single or double presses (use the app).Bluetooth pairing was painless. On initial power up it automatically entered pairing mode and I simple went to the bluetooth settings in my phone, found it and it paired immediately. You can also pair a second device by pressing and holding the function/pairing button.Audio quality is quite good. Sounds are rich and there’s surprisingly good bass. Using the app you can customize the sound a little as it has some preset modes and a rudimentary equalizer. The built-in modes are music, gaming, and “spatial sound”. Music mode is basically unaltered but you can adjust the equalizer yourself. Gaming mode pumps up the bass and treble. Spatial sound mode tries to make it sound 3D but really just adds reverb effects. I’ll never use this mode.Noise cancelling is good. On a scale of 1-10 for headphones I’ve tried I’d rate this about a 7. Does a good job of killing background noise but some quieter sounds still get through. The noise cancelling is sensitive to the direction the sound is coming from. Probably needs more microphones like high-end units have. You can adjust the noise cancelling from high, medium, wind reduction. Then there’s an “ambient sound” mode that basically amplifies the outside sound. Lastly you can completely turn off noise cancelling.Overall build quality is a mixed bag. Some things like the comfort items like the head band and ear pads are very good so the headphones are very comfortable to wear. However the plastic used feels very thin and not very high quality. The tradeoff I guess is that these headphones are very light so that’s good from a comfort perspective, but not so great for build quality.The huge problem though is that the hinges and pivot points where where the ear cups attach to the band creak and pop anytime you move your head. And it’s quite loud in the headphones. Seems to get amplified by the noise cancelling. So this is a huge problem for such a decent product to be let down by this simple build quality problem. Nobody wants their headphones to be creaking and popping when they move their head!Sound quality and noise cancellation are good enough that if they could just fix the build quality issues and maybe add a carrying case (or at least a bag) these would be excellent low end and inexpensive headphones.

I have only used the headphones for the setup and half a dozen songs will give it a full shakedown soon get the headphones finely tuned with the app but they sound great fit well 😁👍

値段に見合った商品だと思います。サウンドモードを立体音響に設定するとコンサートホールにいるような感覚になり感動したのですが、音が若干のびている感じ(音が下がる)がして残念でした。それ以外は問題なく満足です。
