These are the best headphones from Sony. Previously I used Sony headphones but they're entry-level headphones. I also used headphones from other brands like Sennheiser, One Audio and JBL but all of them are entry-level headphones. This is the first time I bought high-end headphones and I trust Sony. You can't go wrong with Sony as per my experience. Coming to the headphones, I already knew that these were best. However, I researched thoroughly on YouTube and read many articles for almost 3 months before buying these. I want to get the best value for the price. These headphones are costly and I don't want to go wrong with my purchase decision.Build quality: These are made of high-quality plastic and feel lightweight and comfortable to wear for longer durations. The only thing is, that the headband is thin and hurts a little on my head after wearing it for a few hours. Just move or adjust it a little and I'm good to go for another hour.Sound quality: It's Sony, no need to brag about sound quality. Sony is known for sound clarity. Every small musical instrument is heard in great detail. I can't forget my first experience of listening to music using these headphones. I'm blown away by the details and the clarity of sound.Battery life: It is mentioned 30 hours. Seems to be true. Headphones will easily last up to two days of mixed usage.Noise cancellation (N.C.): These headphones are my first experience with noise cancellation. When NC is turned on, it is silent. Zero noise. But after a few days, I realised that I could still hear voices from other people when they were shouting or talking loudly. It's good not to completely block all sound.Update on N.C.:I want to address one thing people who are saying that NC is not good. I think they feel like that because of the adaptive NC feature in the Sony headphones app. Due to this feature, the level of Noise cancelling is adjusted automatically according to the surroundings. I know it doesn't work 100% accurately every time. It works sort of 70 - 80 % accurately depending on the surroundings. That's why some people complain that NC is not completely silent or perfect. Some are complaining there is no option to disable the adaptive NC feature. It is available in the Sony headphones app after the latest update. We can also manually disable the adaptive NC of headphones using the app. I mentioned these details because some people may not be aware of these features available in the headphones app.Note: When NC is turned on, a sound pressure is created between ears and headphones. So there is a vacuum-like seal between ears and headphones and it blocks external sound. I'm not sure how NC works. This is the first time for me experienced noise cancellation. It was a shock and a surprise feeling when NC was on. My brother got scared due to this effect. I got used to it now. Check the Sony manual regarding the safety of NC. In the Sony Headphones Connect app, there is a safe listening setting. Please follow it and you don't need to worry about your ears getting damaged due to headphones. I have attached screenshots of the same. Please check.Final Verdict: I can say that these headphones are the best consumer headphones. Audiophile headphones are different that's why I mentioned them as the best consumer headphones. Most people who use them will love them.
