Headphones Sennheiser CX 300-II Precision: reviews, specs, photos

Today we will review the Sennheiser CX-300 II Precision headphones. Let's talk about their technical characteristics, advantages and disadvantages, as well as ways to distinguish fake. In addition, we compare them with the next in the series model - CX-400.

Basic parameters

Let's start with an external examination. The first thing that catches your eye is the lack of a wheel that adjusts the sound. On the one hand, this is a huge drawback, because every time you get the player to change the volume, it's very inconvenient, but here it is worth looking at reviews of the CX-400. It turns out that users of the newer version are very unhappy with the fact that their model has a sound controller, because it turned out to be extremely sensitive and reacts to the slightest touch. There are often cases when he switches under clothes. In addition, there are problems when the CX-400 starts to mess up the sound, and this is corrected only by changing the position of the regulator. Thus, Sennheiser CX-300 II Precision, rather, wins compared to the next generation, because he has such problems simply can not be.

To connect to the gadget, the CX-300 uses an L-shaped contact, but it's an amateur. Someone is more comfortable with the plug being straight and sticking out of the way, but it's much better for someone to walk parallel to the phone's case.

To the same dubious merits-disadvantages is the asymmetrical wire. For those who do not understand: the length of the wire of each earpiece is different, so that the junction is somewhere near the cheek, and not under the clothes.


Complete with the Sennheiser CX-300 II Precision, there is a set of three-pair ear cups, unlike the CX-400, which have as many as 6. On the one hand, it allows at least a little, but lower the price, on the other, it will be a bit harder for you to pick up Most convenient for you personally.

Also, according to reviews, the native ear cups do not hold very well, so losing them is a trifling affair. It is recommended to immediately buy an additional set, so that later there were no surprises.

In general, the headphones provide a good sound insulation, no complaints about their quality. According to one of the comments, the CX-300 at 2/3 of the volume allows you to hear ads in the subway, but overlap with outside noise. In addition, at this level of sound, they do not cut a hearing and do not cause a headache.


And now let's look at the technical parameters of the Sennheiser CX-300 II Precision. Despite the fact that we are dealing with ordinary headphones, "bananas", their characteristics can be envied by many "monitors."

Sennheiser CX-300 II Precision headphones (in-channel) black (and any other colors) have a narrower frequency range than their successor - CX-400, and is limited to 19-21 thousand Hz. According to the comments of users, this parameter does not greatly affect the sound quality, especially if a normal player is used. At the same time, these headphones receive a huge number of negative feedback from the rockers. The sound is "like a pipe" and is suitable for listening except that club music.

Impedance 16 OM is the same for both models we are considering, which allows us to speak about equal sound. The sensitivity varies by only 1 dB and is not able to significantly affect the difference in sound. Moreover, according to customers, the Sennheiser CX-300 II Precision White has a wonderful sound and does not cause any complaints from bass lovers.


The headphones are connected via a 1.2 meter long cable. This allows you to store the sound source in any convenient place, whether it is a backpack, a pocket of pants or a jacket lining.

The connection is made via a 3.5 mm mini jack. So you can use the Sennheiser CX-300 II Precision Silver as an audio output with the vast majority of modern multimedia technology.

Also worth noting is the quality of these components. If the owners of the model CX-400 left complaints about the brittle wires and the bursting rubber cover of the plug, in this case, no negative feedback was received.


In the standard kit, headphones are supplied as follows:

  • Three pairs of ear-cups;
  • Storage and transportation case;
  • Headphones of a certain color.

As you already guessed from the article, the colors of the CX-300 are not very diverse. In most cases, you can choose from black, white or silver models. But there are also more extravagant options. However, here you can already think about whether the headphones you offer are counterfeit.


We have already voiced part of the reviews during the review, but, perhaps, something was missed. So let's gather the opinions of buyers in one place and decide how much this product corresponds to the declared characteristics and quality.

Most users of the CX-300 note the following positive aspects of this device:

  • build quality;
  • equipment;
  • Sound, which, despite the too heavy bass, remains at altitude.

It is quite expected, given the average price of this device 1800 rubles. However, in every barrel of honey there is a fly in the ointment. We are talking about flaws that can discourage the desire to buy the Sennheiser CX-300 II Precision Black, even among the most gambling consumers.

The main problem of these headphones was the left speaker. According to users, it is he who comes first out of order, because of which further use becomes impossible. However, the source of this problem was found. One of the buyers dismantled the broken earpiece. It turned out that the manufacturer does not make knots on the wires, so that they do not come off and are not pulled out the capsules. Accordingly, due to regular physical impact, they are out of order.

However, this defect is often found on other models of this manufacturer, which allows you to think about the integrity of the manufacturer. But here it is everyone's business whether or not to buy the Sennheiser CX-300 II Precision black, the reviews of which allow them to assess 4.5 points.


The main question that interests the buyers of Sennheiser CX-300 II Precision: "How to distinguish a fake?" We will start from the very first aspect. How not to buy a fake, because in stores often do not even let you listen to the sound of the device? How not to fall into the clutches of scammers? Let's look at some external signs.

  • Packing . The plastic container in which the headphones are located should have flaps on each side - special holders that do not allow them to fall off the shelf if the package is installed vertically.
  • The original container is 1 centimeter thinner than the counterfeit container. Of course, on the spot you will have nothing to compare with, but even by eye you can see the excessive massiveness of the package.
  • On the reverse side you can see two inscriptions - Enhanced Bass and Noise Isolation. Their absence may indicate that you have a Chinese-made product in your hands.
  • The inner liner also includes a warranty for the device - 2 years. There are no such copies on counterfeit copies.
  • Another important feature is the presence on the packaging of the QR code and the identifier. The manufacturer maintains a record of each individual product, therefore, counting the code, you can find out if you have the original in your hand. If this is not possible, then try comparing the IDs on different packages. Stores selling fakes often print the same sequence.
  • The package itself should not have a Russian language. But there must be a sticker indicating the importer - LLC "Sennheiser Audio".

Forgery or ...

Of course, after buying headphones in the store, you will no longer be concerned about their authenticity. After all, money is spent, and you need only use the goods for their intended purpose. But some minds still went further and dismantled the headphones by their components in order to reveal all possible inconsistencies:

  • If you cut the cable, then the original Sennheiser CX-300 II Precision will have four wires, and for the forgery - three. At the same time, real ones are used to increase the strength of the Kevlar vein of yellow color. The "left" headphones use white plastic.
  • If you carefully examine the "gags" yourself, you can find signs of polishing rings for fakes. They will look more shiny, while the original has a more matte color.
  • You can pay attention to the quality of the grille in the headphones. These Sennheiser have a straight, but slightly bent at the edges of the form, and Chinese consumer goods - absolutely smooth grating.
  • Consider the capsule. The first thing that catches your eye is glue of different colors. In the original, it should be black. And the fake itself is more flimsy. Also, real headphones in the center of the core should have a small ledge.


What can I say at last? The CX-300 is a high-quality, high-quality headphone that fully complies with its price category. Those shortcomings that occur in people are often associated with the fact that in pursuit of cheapness fakes are bought. So be careful. The original CX-300 has long been withdrawn from sale, and it is possible to purchase only the CX-300 II. We hope, our advice will help you, and you will not fall for the tricks of scammers.
