To get started, decide where you will use wireless headphones more often: listen to music on the street and in noisy public places or play at the computer. Consider whether you really need a model that weighs more and needs to be recharged.
Next, think about sound quality. For watching TV programs or videos on a computer, the medium model is suitable. Another thing is if you need headphones to listen to music and feel all the nuances of high-quality recordings. You will have to pay more for this. Be sure to try and listen. Some devices are packaged and must not be damaged prior to sale. If the seller is not ready to open the package and let you check the model, then look at another one. Devices may not fit or may not be satisfied with the sound quality. Will have to go back and change.
If you need headphones to listen regularly and for a long time, then choose models with in-ear plugs. Look for the ones that have multiple seals in the kit to find the ones that fit your ears. If you want to walk or listen to music near the household, then choose closed-type devices with good sound insulation.
Regular Bluetooth devices are not capable of delivering the same good sound quality as wired ones. So, if you want clear, surround sound lossless audio recordings, then it is better to pay attention to either expensive models or wired mid-range ones. If both sound quality and convenience when walking and playing sports are important, then you need to look for the best option that will combine all the requirements.
In terms of sound quality, devices with an infrared port or a radio channel show themselves best. They have a narrow frequency range, stereo separation, and noise-to-signal ratio. Expensive models use highly sophisticated sound transmission technologies and offer studio-like quality.
Wireless headphones come in two types of batteries: removable and built-in. Pay attention to this when choosing a device. Removable batteries can be removed and replaced with fresh ones, while built-in batteries need to be recharged. Usually, the reserve of work is enough for 8-12 hours of listening at medium volume.
Manufacturers do not provide exact data. You will have to find out in the process of using it. It is enough to charge at the end of the day so that they are enough for the next. Removable is better to choose AA or AAA standard. These are the most common types of batteries.
Soundproofing, that is, cutting off the listener from extraneous noise, is provided by a noise reduction system. It works according to the way the brain works. Schematically, it looks like this: the loudness depends on the amplitude of the sound waves. The larger it is, the higher the vibrations that meet with the eardrums in the ears scatter. Accordingly, the louder we feel the sound. We reduce it by reducing the amplitude of the sound wave. There are also waterproof headphones available where there is sound and waterproofing both.
There are several ways to do this. The simplest: a partition. Noises from behind the wall and when the door is closed are quieter. The fact is that they are partially extinguished when they encounter a physical barrier. The baffle is a passive way of noise reduction.
Since the use of headphones primarily implies that a person will listen to music a lot, and at the same time actively move, you need to:
- Pick up “gags” in size. They should not fall out, sink into the ear canal or put pressure on it. External ones should also fit snugly to the ears and at the same time not give a big load. That’s why it’s so important to try them on before buying. Don’t be afraid to look stupid, at least jump in place. That’s why you buy wireless headphones.
- Pick up devices with good noise reduction so that they cut off extraneous noise. So you can stay alone with the music, despite the loud extraneous sounds. Be sure to remove your headphones when crossing the road and in other potentially dangerous situations.
Radius of action
Devices that connect via radio can operate hundreds of meters from the source. They are not hindered by obstacles in the form of walls. This is especially important when playing sports. You can put the player nearby and practice quietly.
The radius of devices that use Bluetooth technology is limited to 20 meters, but the quality of communication is not affected by obstacles.
