The quality is top notch, be sure to try it.

Right out of the box, the headphones do not sound as good as we would like. Initially, sibilants are really present and quite a bit there is not enough bottoms.
In order for the headphones to reveal their full potential, they need to be warmed up with special sound files. Warm-up files and a description of how to properly warm up the headphones are easy to find on the Internet.
I warm up like this:
- At a volume of 70-75% - 48 hours,
- The next 48 hours at 75-80% volume.
- And another 24 hours at a volume of 80-85%. Total: 120 hours.
After warming up:
- The sibilants are gone completely and all the cymbals and the rest of the percussion sound very natural.
- Low frequencies have changed by an order of magnitude, not only quantitatively but also qualitatively. There is a lot of bass, but at the same time it does not clog the mids.
- The middle was good. Became even better, even more detailed.
In general, the headphones sounded in the entire frequency range by five plus.
- The sound pressure has also increased and now when listening, you need to set a lower volume on the player.
In my opinion, at the moment, these are the best (after proper warm-up) wired, dynamic, in-ear headphones in the price category up to 4000.

Pros

Sennheiser's new CX 300S headphones outperform the outgoing CX 300-II in almost every way. I have both models of these headphones in stock at the same time, so I can compare them. So, in order: 1. The quality of the wire is excellent. The wire is flat and moderately thick. It does not tangle and almost does not tan in the cold. 2. There was a small, light remote control with one button and a good microphone for answering calls. The remote control with a microphone is located just below the chin. 3. The L-shaped plug has also been improved. It has become more accurate and at the same time more reliable. The contacts on the plug are gold-plated. 4. Headphones are small, comfortable and light. They stay in the ears very well, they do not stick out of the ears. The ears do not get tired of them for a long time. Thanks to their ergonomic design and compact size, they can be worn even in winter under a hat. 5. There are 4 pairs of ear pads, so you can choose the right ones. 6. Sound insulation from external noise is good. 7. Invariable convenient branded leatherette case for storage and carrying is also included. 8. Now about the most important thing - the sound quality. The sound has changed in all respects for the better. Improved and frequency response, and detail, and an imaginary scene. There is no porridge, all instruments sound separately as they should sound. The rest is in the comments.

Cons

There are practically no disadvantages. Rather, these are minor quibbles. 1. Complete ear pads sometimes work as vacuum suction cups. 2. Require warming up. However, any dynamic headphones costing over $50 should be warmed up before use.
