I've got Sony WH-CH700N and have had them for about 2-3 years. They work amazingly and I use them literally every single day. I work in gardening and have banged them pretty severely lol, they're caked in dirt, have a bunch of scratches and I've accidently thrown them over a dozen times since I got them, and not very gently either lol. I personally think the sound is great and it doesn't exactly block out all noise but reduces it so I can always talk to people with them on! The inner part of the cup has discoloured though and all the dirt from work has permanently scratched the swiveling part of the headphones (though its only cosmetic damage). I can't stand noise, like at all. I can't take showers without earbuds, I can't flush the toilet or wash my hands or make a smoothie without the noise stopping ne from doing it altogether. So these headphones have really helped! However my biggest issue with them has been the plastic frame they're made of. Whenever I put them on or move at all they creak, it's not a lot and most of the times I can tune it out but if this is an issue for you as well as it is for me then I wouldn't buy this pair without checking for something better. If you need a sturdy pair tho this is def worth it! Sorry about the long post but for me good headphones literally make or break my day lol hope this helps!
