Vacuum headphones are also called intra-channel. In principle, the features of the technology are more or less clear from the name. They are inserted into the ear canal and plug it. To achieve the necessary tightness and not cause inconvenience to the user, the silicone gasket helps.
Simply put, then any “droplets” with a silicone gasket can be considered vacuum. Thanks to this decision, this class of headphones managed to achieve excellent sound insulation and sound purity. After all, when you insert them into your ear, it turns out that from the speaker the sound goes directly to the membrane through a channel that is reliably isolated from external vibrations. The isolation indicators are encouraging - even, this technology was invented especially for musicians who need to perform on stage and listen to the producer’s orders at the same time. In general, vacuum headphones are the choice of true music lovers who want to enjoy high-quality music and not pay big money for it. Below are some tips to help you choose the best vacuum headphones for yourself.
1. Gaskets. Silicone inserts are a very important part of this device. Because of their shape, vacuum headphones become completely useless if lost. You simply cannot insert the headphones into your ear or they will be scratched. Therefore, it is very important to have a replacement kit. Vacuum headphones of acceptable quality were created in such a way as to tear off these silicone inserts was, to put it mildly, not easy, but situations can be different. In addition, the shape of the auricle of each person is individual. It may happen that the standard form is not suitable for you. Therefore, good manufacturers try to sell at least two sets of gaskets.
2. Depth of landing. Vacuum headphones vary in the depth of thrust into the ear - the so-called landing. Many are afraid to buy too impressive a unit, because immediately a logical question arises: "How do I put this in my ear?" Or they are afraid that too close the speaker to the ear membrane will damage your hearing. In fact, on the contrary, the harm from the headphones is greater, the greater the volume of listening to music, and vacuum headphones with a deep seat provide better sound insulation and can not increase the volume even in noisy places.
3. Logical design and ergonomics. The technology of this type of headphone is such that size does not affect quality. Therefore, it is quite possible to pick up headphones of this size, so that even while listening to music, you can safely wear a hat or not fall for the exam (for example). A separate point is to mention the wire. It is desirable that he had a roller where excess length is wound. In another case, a coiled ball of wires will not only bother you in your pocket, but will also begin to “break off” over time, which will lead to the premature death of a high-quality device.
4. Finally, you should specify the price. These gadgets use very few resources in production and, accordingly, are quite cheap. For example, even Apple’s vacuum earphones can be bought for around $ 30. Therefore, do not chase the super-duper with steep branded "ears" and listen to the excuses of sellers why they are so expensive. For a seemingly insignificant price, you can buy a super-unit. Well, if you still decide to buy expensive vacuum headphones, try not to hang donkey ears as a present.
