Review on Sennheiser HD 4.50 BTNC Bluetooth Wireless Headphones Featuring Active Noise Cancellation in Black and Silver by Wiktor ygado ᠌

These ears should be tried on before buying, as they really do not fit every head. Mine is medium in size, but with large ears, I was afraid that the ears would not fit, but everything fit right into the and does not cause discomfort. If there was a bigger head, then the earplugs would press on the ears for sure. About noise canceling They say that noise canceling is a marketing trick and ing out the dough. I wear them on the subway and on the train. Most of the dull and resonant noises do go away, which is a nice fact if you're watching or listening to something at medium volume. If the noise reduction is turned on, then the sound changes a little, but this is felt only at high volumes. At medium and low volumes, you will not feel this and fully experience the beauty of noise reduction, which will cut off all unnecessary noise. BUT! If you are one of those who listen to music at high volumes and enjoy good b, then all your external noise is blocked and without any noise cancellation due to good pive sound isolation, so I just turn it off and enjoy.
