Review on Headphones Sennheiser CX 300-II, black by Jnis Stepi ᠌

0. After revision (read below) I enjoy the sound, who likes the sound andcomfort without this refinement - "I'm sorry for you. " 1. DIY: A must for everyone! Headphones do not have a hole, which means that when inserted into the ear, the eardrum may turn inside out (it hurts to insert, it is uncomfortable to wear), so you need to do a "bypass", i. E. hole. After this procedure, the frequency response changes beyond recognition, instead of porridge in medium and high - detail and purity, DAMING BASSES LOSE ! (maybe for some perverts this is a minus! ), inserting into the ears and wearing it becomes easy and simple, the noise isolation decreases (this is a plus): full instructions for making a hole and a review of the 300s: ? v=QPkOKIo4vs8 2. My ears in these headphones hear the range from 19 to 18500 Hz (this seems to be the limit of my ears). 3. The balance of the frequency response is slightly crooked (there is a slightly different frequency response in the left and right earphones). 4. An unbalanced wire is neither a plus nor a minus, depending on the situation, this is either + or -. 5. These headphones are entirely Chinese, only the label orders the sinheiser and then sells them. Identical headphones can be found in many othercompanies for 700-800, but I'm not sure if the materials are the same, but this is important.
