I have the WH-CH700N you mentioned. It was more of an impulse buy at Amazon, but they are fine headphones. I compared them in the meantime to other NC headphones in the low to medium price category and I think they compare favorable there. I found them more comfortable to wear than others (e.g. the Sennheisers), the physical control buttons are nice, Bluetooth works flawlessly, battery life is good, and sound is also decent. The downsides are that one can only pair them with a single device at a time (all Sony headphones do that), whereas others can do two devices, and that the noise cancellation is a lot weaker than on the class leaders (Sony 1000XM3 and Bose QC35). Sound quality might be bit weaker too, but I doubt most people would notice. I might want to upgrade to one of those at some point of time. If you have the money, use the headphones more often in noisy environments or just wear them often enough that the pricy doesn't matter too much investing in the class leaders certainly won't be a regrettable decision. I wouldn't go for a non noise cancelling option now anymore. Even in my apartment the sound is better when I can block out the outside street noise.
