A good product, I advise you to try it.

After revision (read below) I enjoy the sound, who likes the sound andcomfort without this refinement - "I'm sorry for you. "
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

My ears in these headphones hear the range from 19 to 18500 Hz (this seems to be the limit of my ears).
The balance of the frequency response is slightly crooked (there is a slightly different frequency response in the left and right earphones).
An unbalanced wire is neither a plus nor a minus, depending on the situation, this is either + or -.
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.

Pros

0. Be sure to read my comment below. 1. DIY headphones, develops the work with hands (in the comment). 2. Frequency response (after "do it yourself"). Very good mids and highs, low as I need, without gouging "boom! boom! ", jamming the rest of the range. 3. The wires are very pleasant, they do not tan in the cold. These are two big pluses. 4. Wires get tangled very reluctantly, due to the thickness and rubberiness (a huge plus) 5. Very nice soft rubber bands. 6. Included is a handy little purse-feeder, in which the ears do not get confused at all and are safe. 7. Very small headphones - they do not stick out of the ears and are comfortable to wear under a hat in winter. 8. Excellent jack (an iron stick that fits into the phone / player), it is large, far from the device (it is convenient to pull it out) and almost never breaks.

Cons

1. As for the merits, here is "Do it yourself": without refinement, these headphones simply cannot be inserted into your ears - even try! It's dangerous, painful and uncomfortable, and the sound is like Grandpa Sennheiser himself gets up from the grave every time and defecates in your ears for your money. 2. And I can’t think of any more flaws :(
