Noise canceling works only in transport and in noisy places. In the office, in a working environment, the efficiency is close to 0. If you have a strong enough sound source (I have an ibasso dx80), then noise reduction is not needed in transport either. I bought ears on ebay for 2022. They are definitely worth the money. Has some pros Build quality, ease of use, fit in the ears, pleasant sound. Different cons: These are not shortcomings, but rather nit-picking: the need to mount the control panel so that there is no discomfort from wearing; long cable, had to be wound into a coil; inability to listen in windy weather on the street with noise reduction turned on (the wind blows into the microphones and sounds in the ears).
