I compared these headphones with Dali IO6, and so Dali, in my opinion, play an order of magnitude better. But in terms of manufacturability, noise reduction, Sony design is better in my opinion, in view of this, I took them. Pros below: Headphones are of good quality. Build for 5. They hold a charge for a long time. Convenient touch control on the earpiece. Possibility to adjust noise reduction according to different parameters. Function to stop playback when removing the headphones. etc. Has some cons After listening to the reviews of bloggers on the Internet, I decided to purchase "top" headphones in their price category. As a result, I am disappointed in the sound. The old Sennheiser 449s played better, at least the bass was richer and deeper. These Sony, no matter how I tried to adjust the equalizer, did not manage to get a voluminous rich sound. Yes, the sound is good, the highs do not crumble, the middle is also without dips, the bass is just good, but nothing more. Before buying, I recommend going to Dr. Head or Remote control and listening there, comparing with other brands.
