Active noise canceling has no way to deal with complex high pitched noise, such as a baby crying. Maybe in the future someone will reach that point but for now it's only good for predictable, and especially low frequency, noise.
- SlowRobotAhead 7y agoDo you own the 700s? Because I can tell you without a doubt there is noise canceling on the entire range, not as great as killing engine noise, but the difference between 10, 5, OFF is noticeable everywhere. In my example I had music on, but what the noise canceling does is allow for a very low volume of music vs trying to down everything out. I encourage you to try and put a newborn to sleep if you don’t think the crying can be predictable.
- eyegor 7y agoI haven't specifically used the 700s but I have tried tons of different nc implementations. And by predictable, I mean "a milliwatt chip can record, analyze, and reproduce an inverted signal in real time". What sounds predictable to a human ear can be awfully complicated when you actually look at the signal on a frequency plot. Audio engineering is hard. There aren't many things that active nc can handle well without horrible distortions. I haven't heard any audio tech that has tried to deal with complex signals due to this effect, which isn't really acceptable in headphones. It turns into a weird digital sounding blips randomly interspersed, occasionally canceling things out.
- SlowRobotAhead 7y agoOk, so just to recap; we have my first hand anecdote of compairing the hot Sony to the hot Bose, and to you telling me I’m wrong and I must be wrong because despite you having never touched the Bose 700, “it’s a technology”. Ok, just wanted to make sure I had that right.
