Today, no modern person can do without headphones. Their main purpose is listening to music. Therefore, they should be distinguished by high-quality sound, be inexpensive and convenient, so that you can take with you anywhere. And precisely because of such requirements, the Sennheiser series was born - wireless headphones from a German manufacturer.
Signal transmission method
I must say that the Sennheiser series (wireless headphones) is only gaining its popularity, but it has a great future ahead. The sound signal is transmitted to the device, depending on its type, by radio waves or via Bluetooth technology.
The first method is significantly ahead in terms of the quality of the transmitted signal and range. The thing is that no household object can prevent the propagation of radio waves - they easily penetrate concrete walls, wooden partitions, and metal. In connection with this interference, there is simply nowhere to appear.
On the other hand, Sennheiser RS wireless headphones using wave type data transfer are very expensive and rather bulky - professional devices are usually available on the market.
Gadgets using Bluetooth technology cannot boast a large range. They are designed to listen to music from the phone in your pocket. In this situation, you do not have to worry about sound quality. At the same time, their cost is much less than radio wave devices.
Golden mean
The German company is just starting to increase its production in the field of mobile devices and has released a small line of models. Among all the representatives it is worth highlighting the Sennheiser 120 wireless headphones, located between 110 and 140 representatives.
I immediately want to note their stylish design and convenient layout - under the three pillows made of foam rubber that envelope the inside of the headband made of plastic, there are two steel plates that charge the batteries. The ear pads are finished with viscose fabric, tightly “clasp” the auricles, but at the same time they do not make them sweat, do not squeeze and do not rub the skin.
One cannot but rejoice at the price-to-sound quality ratio - for a budget option, the quality of the output sound is quite high. Sennheiser devices - wireless headphones - transmit signals in the radio frequency range. To do this, a transmitter-base is connected to a laptop, a music center, which is also a charger.
The disadvantages of wireless headphones
The first drawback that should be mentioned is inconvenient control. On the speaker housing are volume and key controls, which are not very easy to hit with your fingers. But if you adapt, this problem will practically disappear.
The second disadvantage is the small radius of action. The manufacturer announced a 100-meter communication range, in practice, the signal quality begins to fall after 30 meters, if you are in the room.
As a minus, one can note the relatively low sound quality that Sennheiser (wireless headphones) possess in relation to wired devices. Among the radio equipment, they certainly occupy a leading position.
