Amazing headphones. The build quality is very good, which is why they are a bit heavier than the QC35ii. However, I would say the weight is ideal, meaning it didn't bother me even after prolonged use. The sound quality is truly indescribable. The best I have ever heard. Excellent detail in the highs and mids, meaning you will notice sounds in your music that you didn't know were there. The bass is incredibly clean and not overpowering. Overall, the sound is flat, meaning it plays the music exactly as it is, without any extra bass, highs, or mids. In other words, the sound is flat. But most likely, if you are reading this review, you are interested in the active noise-canceling (ANC) feature. The headphones do an exceptional job of isolating noise. Through the app, you can adjust the noise isolation on a scale from 0 (none) to 10 (maximum). Noise from cars, computers, and conversations around you disappear. Additionally, there is an Ambient Sound mode where, when you wear the headphones and someone speaks to you, you can activate it with the press of a button. This stops the music and activates the microphones, allowing you to hear the person speaking without hearing the surrounding noise. Overall, the headphones are exceptional. The only negative is their price. If you are interested in buying headphones with active noise-canceling at a lower price, I would recommend the Sony WH-1000XM3. Also, for hip-hop and music in general where you want to enjoy the bass, I would not recommend the Bose 700. The Sony headphones have a punchier bass, and through the app, there is an equalizer adjustment, something that these headphones do not have, and you would need to use another app. I would recommend JetAudio+ and Wavelet for apps with excellent equalizers.
August 2020
The headphones received an update that includes an equalizer, and the app (Android) has improved significantly. With the new update, I would recommend the headphones for their sound, active noise-canceling, and convenience. They are worth every penny. If you have the budget and desire the best sound and active noise-canceling, it is an excellent choice that you will not regret.
CAUTION REGARDING COLOR
I bought the white color, which is very beautiful, but it did not withstand prolonged exposure to the sun. The headband started turning yellow, which I was able to remove with a little rubbing. However, this is something I did not expect from a company like this. That's why I searched a bit online and couldn't find another user who had a similar problem with the white color. Overall, it's not very noticeable, and personally, it doesn't bother me because I chose this company for the sound, and it left me extremely satisfied.
